     TECHNICAL FIELD 
     This application relates to the intelligent vehicle or self-driving field, and in particular, to a vehicle-mounted device information display method, an apparatus, and a vehicle. 
     BACKGROUND 
     A self-driving technology relies on cooperation of artificial intelligence, visual computing, radar, a monitoring apparatus, and a global positioning system, so that a motor vehicle can implement self-driving without an active manual operation. Because the self-driving technology does not require a human to drive a motor vehicle, can theoretically avoid human driving mistakes effectively, reduce traffic accidents, and improve road transportation efficiency, the self-driving technology attracts increasing attention. 
     During self-driving, a vehicle-mounted device inside a vehicle may display a self-driving interface. A lane in which the vehicle is located and other vehicles located near the vehicle may be displayed on the self-driving interface. However, as a road surface environment becomes increasingly complex, display content of an existing self-driving interface cannot satisfy requirements of a driver. 
     SUMMARY 
     Embodiments of this application provide a vehicle-mounted device information display method, an apparatus, and a vehicle, to enrich display content of a self-driving interface. 
     According to a first aspect, this application provides a vehicle-mounted device information display method, including: obtaining information about lane lines of a road surface on which a first vehicle is located, where the lane lines are at least two lines on the road surface that are used to divide different lanes; and displaying, based on the information about the lane lines, virtual lane lines whose types are consistent with those of the lane lines. 
     In an embodiment of this application, the virtual lane lines consistent with the lane lines corresponding to the obtained information about the lane lines are displayed on a self-driving interface, so that a driver can see, from the self-driving interface, the virtual lane lines corresponding to the types of the actual lane lines of the traveling road surface in this case. This not only enriches display content of the self-driving interface, but also improves driving safety. 
     It should be noted that “consistent” herein does not emphasize that the virtual lane lines are exactly the same as the lane lines of the road surface, and there may always be some differences between the virtual lane lines displayed by using a computer screen and the actual lane lines. This application is intended to indicate an actual lane to the driver for reference. The lane lines indicated in an indication manner are close to the actual lane lines as much as possible. However, presented effects of the lines may be different from those of the actual lane lines in terms of a color, a shape, a material, and the like. Further, other indication information may be displayed in addition to the virtual lane lines. 
     In an embodiment, the obtaining information about lane lines of a road surface on which a first vehicle is located includes: obtaining information about lane lines of a lane in which the first vehicle is located. 
     In an embodiment, the lane lines include at least one of the following lane lines: a dashed line, a solid line, a double dashed line, a double solid line, and a dashed solid line. It should be noted that types of the virtual lane lines displayed on the self-driving interface may be consistent with those of the actual lane lines, for example, shapes thereof are consistent. 
     In an embodiment, the lane lines include at least one of the following lane lines: a dashed white line, a solid white line, a dashed yellow line, a solid yellow line, a double dashed white line, a double solid yellow line, a dashed solid yellow line, and a double solid white line. It should be noted that shapes and colors of the virtual lane lines displayed on the self-driving interface may be consistent with those of the actual lane lines. 
     In an embodiment, the method further includes: obtaining information about a non-motor vehicle object on the road surface; and displaying, based on the information about the non-motor vehicle object, an identifier corresponding to the non-motor vehicle object. 
     In an embodiment, the method further includes: 
     receiving a sharing instruction, where the sharing instruction carries an address of a second vehicle; and

     In an embodiment, the method further includes: 
     receiving first shared information sent by a server or the second vehicle, where the first shared information includes the location information of the non-motor vehicle object; and 
     displaying an obstacle prompt on a navigation interface when the first vehicle enables navigation, where the obstacle prompt is used to indicate the non-motor vehicle object at a location corresponding to the location information. 
     In an embodiment, the non-motor vehicle object includes at least a road depression, an obstacle, and a road water accumulation. 
     In an embodiment, the method further includes:

This improves driving safety. 
     In an embodiment, the method further includes: 
     displaying a ninth area based on a first traveling speed of the first vehicle; and

     The radar  126  may include an electromagnetic wave transmitting portion and receiving portion. The radar  126  may be implemented as a pulse radar mode or a continuous wave radar mode in a principle of radio wave transmission. The radar  126  in the continuous wave radar mode may be implemented as a frequency modulated continuous wave (FMCW) mode or a frequency shift keying (FSK) mode based on a signal waveform. 
     The radar  126  may use an electromagnetic wave as a medium, to detect an object based on a time of flight (TOF) manner or a phase-shift manner, and detect a location of the detected object, a distance from the detected object, and a relative speed of the detected object. To detect an object located before, behind, or beside a vehicle, the radar  126  may be configured at an appropriate location of an exterior of the vehicle. The radar  126  may use a laser as a medium, to detect an object based on a TOF manner or a phase-shift manner, and detect a location of the detected object, a distance from the detected object, and a relative speed of the detected object.

     In an embodiment, to obtain a video of the exterior of the vehicle, the camera  130  may be at an appropriate location of the exterior of the vehicle. For example, to obtain a video of a front of the vehicle, the camera  130  may be configured in close proximity to a front windshield inside the vehicle. Alternatively, the camera  130  may be configured around a front bumper or a radiator grille. For example, to obtain a video of a rear of the vehicle, the camera  130  may be configured in close proximity to rear window glass inside the vehicle. Alternatively, the camera  130  may be configured around a rear bumper, a trunk, or a tailgate. For example, to obtain a video of a side of the vehicle, the camera  130  may be configured in close proximity to at least one side window inside the vehicle. Alternatively, the camera  130  may be configured around a side mirror, a mudguard, or a car door. 
     The control system  106  controls operations of the self-driving apparatus  100  and components of the self-driving apparatus  100 . The control system  106  may include various elements, including a steering system  132 , a throttle  134 , a brake unit  136 , a sensor fusion algorithm  138 , a computer vision system  140 , a route control system  142 , and an obstacle avoidance system  144 .

In another embodiment, the brake unit  136  may convert kinetic energy of the wheels  121  into a current. The brake unit  136  may alternatively use another form to reduce a rotational speed of the wheels  121 , so as to control the speed of the self-driving apparatus  100 . 
     The computer vision system  140  may operate to process and analyze an image captured by the camera  130 , so as to recognize objects and/or features in the ambient environment of the self-driving apparatus  100 .

The peripheral device  108  may include a wireless communication system  146 , a vehicle-mounted computer  148 , a microphone  150 , and/or a speaker  152 . 
     In some embodiments, the peripheral device  108  provides means for a user of the self-driving apparatus  100  to interact with the user interface  116 . For example, the vehicle-mounted computer  148  may provide information for the user of the self-driving apparatus  100 . The user interface  116  may further operate the vehicle-mounted computer  148  to receive user input. The vehicle-mounted computer  148  may perform operations through a touchscreen. In other cases, the peripheral device  108  may provide means used by the self-driving apparatus  100  to communicate with another device located in a vehicle. For example, the microphone  150  may receive audio (for example, a voice command or another audio input) from the user of the self-driving apparatus  100 . Likewise, the speaker  152  may output audio to the user of the self-driving apparatus  100 . 
     The wireless communication system  146  may communicate with one or more devices directly or through a communication network. For example, the wireless communication system  146  may use third generation (3G) cellular communication such as code division multiple access (CDMA), EVDO, or global system for mobile communication (GSM)/general packet radio service (GPRS), or fourth generation (4G) cellular communication such as long term evolution (LTE), or fifth generation (5G) cellular communication. The wireless communication system  146  may communicate with a wireless local area network (WLAN) by using Wi-Fi. In some embodiments, the wireless communication system  146  may directly communicate with a device by using an infrared link, Bluetooth, or ZigBee. For other wireless protocols such as various self-driving apparatus communication systems, the wireless communication system  146  may include, for example, one or more dedicated short-range communication (DSRC) devices. These devices may include self-driving apparatuses and/or apparatuses at roadside stations that perform public and/or private data communication with each other. 
     The power supply  110  may supply power to the components of the self-driving apparatus  100 . In an embodiment, the power supply  110  may be a rechargeable lithium-ion or lead-acid battery. One or more battery packs of such a battery may be configured as a power supply to supply power to the components of the self-driving apparatus  100 . In some embodiments, the power supply  110  and the energy source  119  may be implemented together, for example, in some pure electric vehicles. 
     Some or all functions of the self-driving apparatus  100  are controlled by the computer system  112 . The computer system  112  may include at least one processor  113 . The processor  113  executes instructions  115  stored in a non-transitory computer-readable medium such as a memory  114 . The computer system  112  may alternatively be a plurality of computing devices that control individual components or subsystems of the self-driving apparatus  100  in a distributed manner. 
     The processor  113  may be any conventional processor, such as a commercially available central processing unit (CPU). Optionally, the processor may be a dedicated device, for example, an application-specific integrated circuit (ASIC) or another hardware-based processor. Although  FIG. 1  functionally illustrates the processor, the memory, and other elements of a computer  110  in a same block, a person of ordinary skill in the art should understand that the processor, the computer, or the memory may actually include a plurality of processors, computers, or memories that may or may not be stored in a same physical housing. For example, the memory may be a hard disk drive, or another storage medium located in a housing different from that of the computer  110 . Therefore, a reference to the processor or the computer will be understood as including a reference to a set of processors, computers, or memories that may or may not operate in parallel. Different from using a single processor to perform the operations described herein, some components such as a steering component and a deceleration component may include respective processors. The processor performs only computation related to a component-specific function. 
     In the aspects described herein, the processor may be located far away from the self-driving apparatus and perform wireless communication with the self-driving apparatus. In other aspects, some of the processes described herein are performed on the processor disposed inside the self-driving apparatus, while others are performed by a remote processor. The processes include necessary operations for performing a single operation. 
     In some embodiments, the memory  114  may include the instructions  115  (for example, program logic), and the instructions  115  may be executed by the processor  113  to perform various functions of the self-driving apparatus  100 , including those functions described above. The memory  114  may also include additional instructions, including instructions used to send data to, receive data from, interact with, and/or control one or more of the travel system  102 , the sensor system  104 , the control system  106 , and the peripheral device  108 . 
     In addition to the instructions  115 , the memory  114  may further store data such as road maps, route information, a location, direction, and speed of the self-driving apparatus, data of other self-driving apparatuses of this type, and other information. Such information may be used by the self-driving apparatus  100  and the computer system  112  when the self-driving apparatus  100  operates in an autonomous mode, a semi-autonomous mode, and/or a manual mode. 
     The user interface  116  is configured to provide information for or receive information from the user of the self-driving apparatus  100 . In an embodiment, the user interface  116  may include one or more input/output devices within a set of peripheral devices  108 , such as the wireless communication system  146 , the vehicle-mounted computer  148 , the microphone  150 , and the speaker  152 . 
     The computer system  112  may control functions of the self-driving apparatus  100  based on input received from each of the subsystems (for example, the travel system  102 , the sensor system  104 , and the control system  106 ) and from the user interface  116 . For example, the computer system  112  may use input from the control system  106  to control the steering system  132  to avoid an obstacle detected by the sensor system  104  and the obstacle avoidance system  144 . In some embodiments, the computer system  112  is operable to provide control over many aspects of the self-driving apparatus  100  and the subsystems of the self-driving apparatus  100 . 
     In an embodiment, one or more of the foregoing components may be installed separately from or associated with the self-driving apparatus  100 . For example, the memory  114  may be partially or completely separated from the self-driving apparatus  100 . The foregoing components may be communicatively coupled together in a wired and/or wireless manner. 
     In an embodiment, the foregoing components are merely examples. In actual application, components in the foregoing modules may be added or deleted based on an actual requirement.  FIG. 1  should not be understood as a limitation on this embodiment of this application. 
     A self-driving car traveling on a road, such as the foregoing self-driving apparatus  100 , may recognize an object in an ambient environment of the self-driving apparatus  100  to determine adjustment on a current speed. The object may be another self-driving apparatus, a traffic control device, or another type of object. In some examples, each recognized object may be considered independently, and a speed to be adjusted to by a self-driving car may be determined based on features of the object, such as a current speed of the object, an acceleration of the object, and a distance between the object and the self-driving apparatus. 
     In an embodiment, the self-driving apparatus  100  or a computing device (for example, the computer system  112 , the computer vision system  140 , and the memory  114  in  FIG. 1 ) associated with the self-driving apparatus  100  may predict an action of the recognized object based on features of the recognized object and a status of an ambient environment (for example, traffic, rain, or ice on a road). In an embodiment, all the recognized object depends on behavior of each other, and therefore, all the recognized objects may be considered together to predict behavior of a single recognized object. The self-driving apparatus  100  can adjust the speed of the self-driving apparatus  100  based on the predicted behavior of the recognized object. In other words, the self-driving car can determine, based on the predicted action of the object, a specific stable state (for example, acceleration, deceleration, or stop) to which the self-driving apparatus needs to be adjusted. In this process, another factor may also be considered to determine the speed of the self-driving apparatus  100 , for example, a horizontal location of the self-driving apparatus  100  on a road on which the self-driving apparatus  100  travels, a curvature of the road, and proximity between a static object and a dynamic object. 
     In addition to providing instructions for adjusting the speed of the self-driving car, the computing device may further provide instructions for modifying a steering angle of the self-driving apparatus  100 , so that the self-driving car can follow a given track and/or maintain safe horizontal and vertical distances from objects (for example, a car on a neighboring lane of the road) near the self-driving car. 
     The self-driving apparatus  100  may be a car, a truck, a motorcycle, a bus, a boat, an airplane, a helicopter, a lawn mower, a recreational vehicle, a playground vehicle, a construction device, a trolley, a golf cart, a train, a handcart, or the like. This is not limited in this embodiment of this application. 
       FIG. 1  is a functional block diagram of the self-driving apparatus  100 . The following describes a self-driving system  101  in the self-driving apparatus  100 .  FIG. 2  is a schematic diagram of a structure of a self-driving system according to an embodiment of this application.  FIG. 1  and  FIG. 2  describes the self-driving apparatus  100  from different perspectives. For example, the computer system  101  in  FIG. 2  is the computer system  112  in  FIG. 1 . 
     As shown in  FIG. 2 , the computer system  101  includes a processor  103 , and the processor  103  is coupled to a system bus  105 . The processor  103  may be one or more processors, and each processor may include one or more processor cores. The system bus  105  is coupled to an input/output (I/O) bus  113  through a bus bridge  111 . An I/O interface  115  is coupled to the I/O bus. The I/O interface  115  communicates with a plurality of I/O devices, such as an input device  117  (such as a keyboard, a mouse, or a touchscreen), a multimedia compact disc (multimedia compact disc)  121 , such as a CD-ROM or a multimedia interface. A transceiver  123  (which may send and/or receive a radio communication signal), a camera  155  (which may capture a scenery and a dynamic digital video image), and an external USB port  125  are included. Optionally, an interface connected to the I/O interface  115  may be a USB port. 
     The processor  103  may be any conventional processor, including a reduced instruction set computing (“RISC”) processor, a complex instruction set computing (“CISC”) processor, or a combination thereof. Optionally, the processor may be a dedicated apparatus such as an application-specific integrated circuit (“ASIC”). Optionally, the processor  103  may be a neural-network processing unit (Neural-network Processing Unit, NPU) or a combination of a neural-network processing unit and the foregoing conventional processor. Optionally, a neural-network processing unit is disposed on the processor  103 . 
     The computer system  101  may communicate with a server  149  through a network interface  129 . The network interface  129  is a hardware network interface, for example, a network interface card. A network  127  may be an external network such as the Internet, or an internal network such as the Ethernet or a virtual private network (VPN). Optionally, the network  127  may alternatively be a wireless network, for example, a Wi-Fi network or a cellular network. 
     The server  149  may be a high-precision map server, and the vehicle may obtain high-precision map information by communicating with a high-precision map server. 
     The server  149  may be a vehicle management server. The vehicle management server may be configured to process data uploaded by the vehicle, and may deliver data to the vehicle through a network. 
     In addition, the computer system  101  may perform wireless communication with another vehicle  160  (V2V) or a pedestrian (V2P) through the network interface  129 . 
     A hard disk drive interface is coupled to the system bus  105 . A hardware driver interface is connected to a hard disk drive. A system memory  135  is coupled to the system bus  105 . Data running in the system memory  135  may include an operating system  137  and an application  143  of the computer system  101 . 
     The operating system includes a shell  139  and a kernel  141 . The shell  139  is an interface between a user and the kernel of the operating system. The shell  139  is an outermost layer of the operating system. The shell  139  manages interaction between the user and the operating system: waiting for input of the user, explaining the input of the user to the operating system, and processing output results of various operating systems. 
     The kernel  141  includes components of the operating system that are configured to manage a memory, a file, a peripheral, and system resources. The kernel directly interacts with hardware. The kernel of the operating system usually runs processes, provides communication between the processes, and provides CPU time slice management, interruption, memory management, I/O management, and the like. 
     The application  143  includes a self-driving-related program, for example, a program for managing interaction between a self-driving apparatus and an obstacle on a road, a program for controlling a driving route or speed of a self-driving apparatus, or a program for controlling interaction between a self-driving apparatus  100  and another self-driving apparatus on the road. 
     A sensor  153  is associated with the computer system  101 . The sensor  153  is configured to detect an ambient environment of the computer system  101 . For example, the sensor  153  can detect animals, automobiles, obstacles, pedestrian crosswalks, and the like. Further, the sensor can detect ambient environments of the animals, the automobiles, the obstacles, or the pedestrian crosswalks. For example, the sensor can detect the ambient environment of animals such as other animals in the ambient environment, a weather condition, and brightness of the ambient environment. In an embodiment, if the computer system  101  is located on the self-driving apparatus, the sensor may be a camera, an infrared sensor, a chemical detector, a microphone, or the like. When being activated, the sensor  153  senses information at preset intervals, and provides the sensed information for the computer system  101  in real time or near real time. 
     The computer system  101  is configured to: determine a driving status of the self-driving apparatus  100  based on sensor data collected by the sensor  153 ; determine, based on the driving status and a current driving task, a driving operation that needs to be executed by the self-driving apparatus  100 ; and send, to the control system  106  (which is shown in  FIG. 1 ), control instructions corresponding to the driving operation. The driving status of the self-driving apparatus  100  may include a driving situation of the self-driving apparatus  100 , for example, a head direction, a speed, a location, and an acceleration, and may also include a status of the ambient environment of the self-driving apparatus  100 , for example, a location of an obstacle, a location and a speed of another vehicle, a location of a pedestrian crosswalk, or a signal of a traffic light. The computer system  101  may include a task abstraction network and a shared policy network that are implemented by the processor  103 . Specifically, the processor  103  determines a current self-driving task. The processor  103  inputs at least one group of historical paths of the self-driving task to the task abstraction network for feature extraction, to obtain a task feature vector representing features of the self-driving task. The processor  103  determines, based on the sensor data collected by the sensor  153 , a status vector representing a current driving status of the self-driving apparatus. The processor  103  inputs the task feature vector and the status vector into the shared policy network for processing, to obtain a driving operation that needs to be performed currently by the self-driving apparatus. The processor  103  performs the driving operation through the control system. The processor  103  repeats the foregoing operations of determining and performing the driving operation, until the self-driving task is completed. 
     In an embodiment, the computer system  101  may be located far away from the self-driving apparatus, and may perform wireless communication with the self-driving apparatus. The transceiver  123  may send a self-driving task, the sensor data collected by the sensor  153 , and other data to the computer system  101 , and may further receive control instructions sent by the computer system  101 . The self-driving apparatus may execute the control instructions received by the transceiver from the computer system  101 , and perform a corresponding driving operation. In other aspects, some of the processes described in this specification are performed on a processor disposed inside a self-driving vehicle, and others are performed by a remote processor, including taking actions required to perform a single operation. 
     As shown in  FIG. 2 , a display adapter  107  may drive a display  109 , and the display  109  is coupled to the system bus  105 . The display  109  may be used for visual display and audio playing of information entered by or provided for a user, and various menus of a vehicle-mounted device. The display  109  may include at least one of a liquid crystal display (LCD), a thin film transistor liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display, a 3D display, and an electronic ink display (e-ink display). The touch panel may cover the display  109 . When detecting the touch operation on or near the touch panel, the touch panel sends the touch operation to the processor to determine a type of a touch event, and then the processor provides corresponding visual output on the display  109  based on the type of the touch event. In addition, the touch panel and the display  109  may alternatively be integrated to implement input and output functions of the vehicle-mounted device. 
     Moreover, the display  109  may be implemented by a head-up display (HUD). Furthermore, the display  109  may be provided with a projection module to output information by projecting an image on a windshield or a car window. The display  109  may include a transparent display. The transparent display may be attached to the windshield or the car window. The transparent display may display a specified picture with specified transparency. To make the transparent display have transparency, the transparent display may include at least one of a transparent thin film electroluminescent (TFEL) display, a transparent organic light-emitting diode (OLED), a transparent LCD, a transmissive transparent display, and a transparent LED (Light Emitting Diode) display. The transparency of the transparent display is adjustable. 
     In addition, the display  109  may be configured in a plurality of areas inside the vehicle.  FIG. 3 a    and  FIG. 3 b    show an internal structure of a vehicle according to an embodiment of this application. As shown in  FIG. 3 a    and  FIG. 3   b,  the display  109  may be configured in areas  300  and  301  of a dashboard, an area  302  of a seat  308 , an area  303  of pillar trims, an area  304  of a car door, an area  305  of a center console, an area of a head lining, or an area of a sunvisor, or may be implemented in an area  306  of a windshield or an area  307  of a car window. It should be noted that the foregoing configuration locations of the display  109  are merely examples, and do not constitute any limitation on this application. 
     In an embodiment of this application, the display may display a human-computer interaction interface, for example, may display a self-driving interface during self-driving of the vehicle. 
       FIG. 4 a    is a schematic flowchart of a vehicle-mounted device information display method according to an embodiment of this application. As shown in  FIG. 4   a,  the vehicle-mounted device information display method includes the following operations. 
       41 : Obtain information about lane lines of a road surface on which a first vehicle is located, where the lane lines are at least two lines on the road surface that are used to divide different lanes. 
     In an embodiment of this application, the lane line may be a traveling vehicle line, a vehicle line next to the traveling vehicle line, or a traveling vehicle line of a crossing vehicle. The lane lines may include left and right lines (lines) that form a lane (lane). In other words, the lane lines are at least two lines on the road surface that are used to divide different lanes. 
     In an embodiment, the first vehicle may obtain an external image or video of the vehicle by using a camera or another photographing device carried by the first vehicle, and send the obtained external image or video to a processor. The processor may obtain, according to a recognition algorithm, the information about the lane lines included in the external image or video. 
     In an embodiment, after obtaining an external image or video of the vehicle by using a camera or another photographing device carried by the first vehicle, the first vehicle may upload the image or video to a vehicle management server. The vehicle management server processes the image, and delivers a recognition result (the information about the lane lines) to the first vehicle. 
     In an embodiment, the first vehicle may detect an ambient environment of a vehicle body by using a sensor (for example, a radar or a laser radar) carried by the first vehicle, and obtain the information about the lane lines outside the vehicle. 
     In an embodiment, the first vehicle may obtain, from a high-precision map server, the information about the lane lines of the road surface on which the first vehicle currently travels. 
     In an embodiment, the first vehicle may determine lane line-related information based on other data (for example, based on a current traveling speed or historical traveling data). 
     In this embodiment of this application, the information about the lane lines may be image information of the lane lines. 
       42 : Display, based on the information about the lane lines, virtual lane lines whose types are consistent with those of the lane lines. 
     In an embodiment of this application, during self-driving of the vehicle, the display  109  may display a self-driving interface. Specifically, after the information about the lane lines of the road surface on which the first vehicle is located is obtained, the virtual lane lines whose types are consistent with those of the lane lines may be displayed on the self-driving interface. 
       FIG. 4 b    is a schematic diagram of a self-driving interface according to an embodiment of this application. As shown in  FIG. 4   b,  the self-driving interface includes a first vehicle  401 , virtual lane lines  402 , and virtual lane lines  403 . The virtual lane lines  402  are lane lines of a lane in which the first vehicle is located. The virtual lane lines  403  are not virtual lane lines corresponding to the lane lines of the lane in which the first vehicle  401  is located, but are also virtual lane lines corresponding to lane lines of a road surface on which the first vehicle  401  is located. 
     In an embodiment, only the virtual lane lines corresponding to the lane lines of the lane in which the first vehicle  401  is located (for example, the virtual lane lines  402  shown in  FIG. 4 ) may alternatively be displayed on the self-driving interface. 
     In this embodiment of this application, types of the virtual lane lines displayed on the self-driving interface may be consistent with those of the actual lane lines, and specifically, shapes thereof may be consistent. Specifically, the lane lines include at least one of the following lane lines: a dashed line, a solid line, a double dashed line, a double solid line, and a dashed solid line. 
     In an embodiment, types of the virtual lane lines displayed on the self-driving interface may be consistent with those of the actual lane lines, and specifically, shapes and colors thereof may be consistent. Specifically, the lane lines include at least one of the following lane lines: a dashed white line, a solid white line, a dashed yellow line, a solid yellow line, a double dashed white line, a double solid yellow line, a dashed solid yellow line, and a double solid white line. 
     For example, a double solid yellow line is drawn on a center of a road to separate a traffic flow traveling in opposite directions. 
     A solid yellow line is drawn on a center of a road to separate a traffic flow traveling in opposite directions, or serves as a marking line for a bus or school bus special stop and is drawn on a roadside to indicate prohibition of parking on the roadside. 
     A solid white line is drawn on a center of a road to separate motor vehicles and non-motor vehicles traveling in a same direction or indicate an edge of a lane, and is drawn on an intersection to serve as a guide lane line or a stopline or guide a vehicle traveling track. 
     A dashed solid yellow line is drawn on a center of a road to separate a traffic flow traveling in opposite directions. A solid line side prohibits vehicles from crossing the line, and a dashed line side allows vehicles to cross the line temporarily. 
     In addition, the lane lines may further include a diversion line, a grid line, and the like. The diversion line may be one or more types of lines, that is, a V-shaped white line or a diagonal line area, disposed based on an intersection terrain, is used for excessively wide or irregular crossroads or crossroads with relatively complicated traveling conditions and interchange ramps or other special places, and indicates that vehicles need to travel along a stipulated route without traveling on the line or across the line. The yellow grid line indicates an area in which parking is prohibited, and indicates exclusive parking spaces when used as a marking line for parking spaces. This means that vehicles are allowed to pass through the line normally, but are not allowed to stay on the line. 
     It should be understood that the self-driving interface may further include other display elements, for example, a current traveling speed of the first vehicle, a speed limit of a current road surface, and other vehicles. This is not limited in this application. 
     It should be noted that “consistent” in this embodiment does not emphasize that the virtual lane lines are exactly the same as the lane lines of the road surface, and there may always be some differences between the virtual lane lines displayed by using a computer screen and the actual lane lines. This application is intended to indicate an actual lane to a driver for reference. The lane lines indicated in an indication manner are close to the actual lane lines as much as possible. However, presented effects of the lines may be different from those of the actual lane lines in terms of a color, a shape, a material, and the like. Further, other indication information may be displayed in addition to the virtual lane lines. 
     In an embodiment of this application, the virtual lane lines consistent with the lane lines corresponding to the obtained information about the lane lines are displayed on the self-driving interface, so that the driver can see, from the self-driving interface, the virtual lane lines corresponding to the types of the actual lane lines of the traveling road surface in this case. This not only enriches display content of the self-driving interface, but also improves driving safety. 
     In an embodiment, the first vehicle may further obtain information about a non-motor vehicle object on the road surface; and display, based on the information about the non-motor vehicle object, an identifier corresponding to the non-motor vehicle object. 
     In an embodiment of this application, the non-motor vehicle object includes at least a road depression, an obstacle, and a road water accumulation, and may further include a pedestrian, a two-wheeled vehicle, a traffic signal, a street lamp, various plants such as a tree, a building, a utility pole, a signal lamp, a bridge, a mountain, a hill, and the like. This is not limited herein. 
     In an embodiment, the first vehicle may obtain the external image or video of the vehicle by using the camera or the another photographing device carried by the first vehicle, and send the obtained external image or video to the processor. The processor may obtain, according to the recognition algorithm, the information about the non-motor vehicle object included in the external image or video. 
     In an embodiment, after obtaining the external image or video of the vehicle by using the camera or the another photographing device carried by the first vehicle, the first vehicle may upload the image or video to the vehicle management server. The vehicle management server processes the image, and delivers a recognition result (the information about the non-motor vehicle object) to the first vehicle. 
     In an embodiment, the first vehicle may detect the ambient environment of the vehicle body by using the sensor (for example, a radar or a laser radar) carried by the first vehicle, and obtain the information about the non-motor vehicle object outside the vehicle. 
     In an embodiment of this application, after the information about the non-motor vehicle object on the road surface is obtained, the identifier corresponding to the non-motor vehicle object may be displayed on an autonomous navigation interface. Specifically, the information about the non-motor vehicle object may include a location, a shape, a size, and the like of the non-motor vehicle object. Correspondingly, the identifier corresponding to the non-motor vehicle object may be displayed at a corresponding location of the non-motor vehicle object based on the shape and the size of the non-motor vehicle object. 
     It should be noted that the identifier corresponding to the non-motor vehicle object may be consistent with the non-motor vehicle object, or may be used as an example and is merely used to indicate the shape and the size of the non-motor vehicle object. 
       FIG. 5 a    is a schematic diagram of a self-driving interface according to an embodiment of this application. As shown in  FIG. 5   a,  the self-driving interface further includes a non-motor vehicle object  501  (a road depression). 
       FIG. 5 b    is a schematic diagram of a self-driving interface according to an embodiment of this application. As shown in  FIG. 5   b,  the self-driving interface further includes a non-motor vehicle object  501  (a road water accumulation). 
       FIG. 5 c    is a schematic diagram of a self-driving interface according to an embodiment of this application. As shown in  FIG. 5   c,  the self-driving interface further includes a non-motor vehicle object  501  (an obstacle). 
     In an embodiment, a lane change indication may further be displayed when the non-motor vehicle object is located on a navigation path indicated by a navigation indication, where the navigation indication is used to indicate the navigation path of the first vehicle, and the lane change indication is used to instruct the first vehicle to avoid a traveling path of the non-motor vehicle object. 
     In an embodiment, when the first vehicle is in a navigation state, the first vehicle may display the navigation indication based on navigation information, where the navigation indication is used to indicate the navigation path of the first vehicle. In this case, when recognizing that the non-motor vehicle object is located on the navigation path indicated by the navigation indication, the first vehicle displays the lane change indication used to instruct the first vehicle to avoid the traveling path of the non-motor vehicle object. 
     It should be noted that, in an embodiment of this application, the first vehicle may obtain the external image or video of the vehicle by using the camera or the another photographing device carried by the first vehicle, and send the obtained external image or video to the processor. The processor may obtain, according to the recognition algorithm, the information about the non-motor vehicle object included in the external image or video. In this case, the information about the non-motor vehicle object may include the size, the shape, and the location of the non-motor vehicle object. The processor may determine, based on the obtained size, shape, and location of the non-motor vehicle object, whether the non-motor vehicle object is on the current navigation path. 
     In an embodiment, after obtaining the external image or video of the vehicle by using the camera or the another photographing device carried by the first vehicle, the first vehicle may upload the image or video to the vehicle management server. The vehicle management server processes the image, and delivers a recognition result (whether the non-motor vehicle object is on the current navigation path or whether the non-motor vehicle object obstructs vehicle traveling) to the first vehicle. 
       FIG. 5 d    is a schematic diagram of a self-driving interface according to an embodiment of this application. As shown in  FIG. 5   d,  a non-motor vehicle object  501  (an obstacle) is located on a navigation path indicated by a navigation indication  502 , and then a lane change indication  503  used to instruct the first vehicle to avoid the traveling path of the non-motor vehicle object is displayed. 
     It should be noted that, the lane change indication  503  may be a strip-shaped path instruction, or may be a linear path instruction. This is not limited herein. 
     In an embodiment of this application, the first vehicle may directly pass through a road depression and a road water accumulation, which is different from an obstacle. If there is an obstacle, the first vehicle needs to circumvent the obstacle. When the navigation indication is displayed, if there is an obstacle on the navigation path indicated by the navigation indication, the lane change indication  503  used to instruct the first vehicle to avoid the traveling path of the non-motor vehicle object may be displayed. The lane change indication  503  may be displayed in a color and/or shape different from those/that of the current navigation indication. The navigation indication  502  may be displayed as a curved indication (as shown in  FIG. 5 e   ) when the first vehicle detours and makes a lane change according to the lane change indication  503 . The navigation indication  502  may be re-straightened for display (as shown in  FIG. 5 f   ) when the first vehicle circumvents the obstacle. 
     In an embodiment, a first alarm prompt may further be displayed when a distance between the first vehicle and the non-motor vehicle object is a first distance; and a second alarm prompt may further be displayed when the distance between the first vehicle and the non-motor vehicle object is a second distance, where the second alarm prompt is different from the first alarm prompt. 
     In an embodiment, a color or transparency of the first alarm prompt is different from that of the second alarm prompt. 
     Specifically, in this embodiment of this application, the first vehicle may obtain the distance between the first vehicle and the non-motor vehicle object by using a distance sensor, and display the alarm prompt based on the distance between the first vehicle and the non-motor vehicle object. The alarm prompt may change with at least two colors based on a distance to an obstacle (a collision danger level), and a smooth transition is made between two adjacent colors as the distance between the first vehicle and the obstacle increases/decreases. 
     In an embodiment, the first vehicle may further receive a sharing instruction, where the sharing instruction carries an address of a second vehicle; and send second shared information to the second vehicle in response to the sharing instruction, where the second shared information includes location information of the non-motor vehicle object. 
     In an embodiment, the first vehicle may further receive first shared information sent by a server or the second vehicle, where the first shared information includes the location information of the non-motor vehicle object; and an obstacle prompt is displayed on a navigation interface when the first vehicle enables navigation, where the obstacle prompt is used to indicate the non-motor vehicle object at a location corresponding to the location information. 
     It can be understood that if a road depression or a road water accumulation is relatively severe or an obstacle is relatively large, vehicle traveling may be seriously affected, and the driver may prefer to know the situation earlier rather than know it until the vehicle approaches the road depression, the road water accumulation, or the obstacle. In this case, predictions cannot be made by using only the sensor of the vehicle. 
     In an embodiment, after information about the road depression, the road water accumulation, or the obstacle is obtained by using a surveillance camera in a traffic system or a sensor of a vehicle that has traveled on the road surface, the information may be reported to the vehicle management server. The server delivers the information to vehicles on roads that include the road depression, the road water accumulation, or the obstacle in a navigation route, so that the vehicles can learn the information in advance. 
     If obtaining the information (the location, the shape, the size, and the like) about the non-motor vehicle object by using the sensor, the first vehicle may send the information about the non-motor vehicle object to another vehicle (the second vehicle). Specifically, the driver or a passenger may perform an operation on the self-driving interface (for example, triggering a sharing control on the display interface and entering the address of the second vehicle, or directly selecting the second vehicle that has established a connection to the first vehicle). Correspondingly, the first vehicle may receive the sharing instruction, where the sharing instruction carries the address of the second vehicle, and send the second shared information to the second vehicle in response to the sharing instruction, where the second shared information includes the location information of the non-motor vehicle object. 
       FIG. 6 a    is a schematic diagram of a self-driving interface according to an embodiment of this application. As shown in  FIG. 6   a,  if a driver A and a driver B agree to travel to a specific place, the driver A starts first, and finds that there is a road depression on a road surface on a passing path. Then, the driver A may touch a display to click a depression prompt, select a sharing control  601  “send to a friend” (as shown in  FIG. 6 a   ), and select “the driver B” (which is equivalent to entering the address of the second vehicle in this case), so that the driver B can receive the road depression prompt in advance. 
     Correspondingly, an example in which the first vehicle receives shared information is used. The first vehicle receives the first shared information sent by the server or the second vehicle, where the first shared information includes the location information of the non-motor vehicle object; and the obstacle prompt is displayed on the navigation interface when the first vehicle enables navigation, where the obstacle prompt is used to indicate the non-motor vehicle object at the location corresponding to the location information. 
       FIG. 6 b    is a schematic diagram of a self-driving interface according to an embodiment of this application. As shown in  FIG. 6   b,  a right figure in  FIG. 6 b    is a navigation interface, the navigation interface includes a navigation map, a thick solid line in the figure is a navigation route, an arrow indicates a current location to which the vehicle travels, a location marked by a black dot on the thick solid line indicates road depression information collected by the vehicle management server or road depression information sent by another vehicle, and a depression prompt  602  is displayed on the current navigation interface of the first vehicle. 
     In this embodiment of this application, the first vehicle may further display different navigation indications based on traveling speeds. 
     In an embodiment, the first vehicle may further obtain the navigation information of the first vehicle, and display the navigation indication based on the navigation information, where the navigation indication is used to indicate the navigation path of the first vehicle. 
     In an embodiment of this application, the navigation indication includes a first navigation indication or a second navigation indication. The first navigation indication is displayed based on a stationary state of the first vehicle; and the second navigation indication is displayed based on a traveling state of the first vehicle, where the first navigation indication is different from the second navigation indication. 
     Specifically, a display color or display transparency of the first navigation indication is different from that of the second navigation indication. 
       FIG. 7 a    is a schematic diagram of a self-driving interface according to an embodiment of this application. As shown in  FIG. 7   a,  the self-driving interface includes a navigation indication  701 , and the navigation indication  701  indicates a navigation path of the first vehicle. A first navigation indication  701  is displayed (as shown in  FIG. 7 b   ) when the first vehicle determines that a current state is a stationary state or that a traveling speed is lower than a preset speed. A second navigation indication  701  is displayed (as shown in  FIG. 7 c   ) when the first vehicle determines that a current state is a traveling state or that a traveling speed is higher than a preset speed. A color of the second navigation indication  701  shown in  FIG. 7 c    is different from that of the first navigation indication  701  shown in  FIG. 7   b.    
     In an embodiment of this application, different navigation indications are displayed based on traveling statuses of the first vehicle, so that the driver or a passenger can determine a current traveling status of the vehicle based on display of the navigation indication on the navigation interface. 
     In an embodiment of this application, the first vehicle may further enable visual elements (e.g., virtual lane lines, road surfaces of lanes, navigation indications, and the like) on the autonomous navigation interface to change in at least one of a color, brightness, and a material based on a current environment (e.g., information about weather, time, and the like) in which the first vehicle is situated. 
     In an embodiment, the navigation indication includes a third navigation indication or a fourth navigation indication. The first vehicle may display the third navigation indication based on a first environment of the first vehicle; and display the fourth navigation indication based on a second environment of the first vehicle, where the first environment is different from the second environment, and the third navigation indication is different from the fourth navigation indication. 
     In another embodiment, the first vehicle may display a first lane based on the first environment of the first vehicle, and display a second lane based on the second environment of the first vehicle. The first lane and the second lane are lanes in which the first vehicle travels, or lanes of the road surface on which the first vehicle is located. The first environment is different from the second environment, and the first lane is different from the second lane. 
     In an embodiment, the first vehicle may enable the visual elements (the virtual lane lines, the road surfaces of the lanes, the navigation indications, and the like) on the autonomous navigation interface to change in the at least one of a color, brightness, and a material based on the current environment (the information about weather, time, and the like) in which the first vehicle is situated. 
     In an embodiment, the first environment includes at least one of the following environments: a weather environment in which the first vehicle is situated, a road surface environment in which the first vehicle is situated, a weather environment of a navigation destination of the first vehicle, a road surface environment of the navigation destination of the first vehicle, a traffic congestion environment of a road on which the first vehicle is located, a traffic congestion environment of the navigation destination of the first vehicle, or a brightness environment in which the first vehicle is situated. 
     The weather environment may be obtained by connecting a network to a weather server. The weather environment may include a temperature, humidity, a strong wind, a rainstorm, a snowstorm, and the like. The brightness environment may be brightness of the current environment in which the vehicle is situated, and may indicate current time. For example, if the current time is a morning, colors of the virtual lane lines, the road surfaces of the lanes, the navigation indications, and the like are increased compared with normal brightness or become lighter than normal brightness. If the current time is an evening, colors of the virtual lane lines, the road surfaces of the lanes, the navigation indications, and the like are decreased compared with normal brightness or become deeper than normal brightness. 
     For example, if the current time is a snowy day, materials of the virtual lane lines, the road surfaces of the lanes, the navigation indications, and the like are displayed as being covered by snow. 
     For example, when the current weather environment is severe weather (such as a strong wind, a rainstorm, or a snowstorm), the visual elements such as the virtual lane lines, the road surfaces of the lanes, and the navigation indications are enhanced for display. For example, colors are brighter (purity is improved), or brightness is increased, or enhanced materials are used. 
       FIG. 8 a    is a schematic diagram of a self-driving interface according to an embodiment of this application. As shown in  FIG. 8   a,  a road surface environment in which the first vehicle travels is snow, and correspondingly a road surface material on the autonomous navigation interface is displayed as being covered by snow. 
       FIG. 8 b    is a schematic diagram of a self-driving interface according to an embodiment of this application. As shown in  FIG. 8   b,  a road surface environment in which the first vehicle travels is desert, and correspondingly a road surface material on the autonomous navigation interface is displayed as desert. 
     In an embodiment of this application, the first vehicle may display the first lane based on the first environment of the first vehicle, and display the second lane based on the second environment of the first vehicle. The first lane and the second lane are the lanes in which the first vehicle travels, or the lanes of the road surface on which the first vehicle is located. The first environment is different from the second environment, and the first lane is different from the second lane. The driver or a passenger can obtain, based on display of the autonomous navigation interface, the current environment in which the vehicle is situated, especially at night or in other scenarios with relatively low brightness. This improves driving safety. 
     In an embodiment of this application, the first vehicle may display a corresponding image on the self-driving interface based on a geographical location of a navigation destination. 
     In an embodiment, the first vehicle may obtain a geographical location of the navigation destination of the first vehicle, and display a first image based on the geographical location, where the first image is used to indicate a type of the geographical location of the navigation destination of the first vehicle. The type of the geographical location may include at least one of the following: city, mountain area, plain, forest, or seaside. 
     In an embodiment of this application, the first vehicle may obtain the geographical location of the navigation destination of the first vehicle by using a GPS system, or obtain the geographical location of the navigation destination of the current vehicle by using a high-definition map, and further obtain attribute information (types) of the geographical locations. For example, the geographical location of the navigation destination of the first vehicle may belong to a city, a mountain area, a plain, a forest, a seaside, or the like. The attribute information (types) of the geographical locations may be obtained from a map system. 
     In an embodiment of this application, after obtaining the geographical location of the navigation destination and the type of the geographical location of the navigation destination, based on the type of the geographical location, the first vehicle may present a long-shot image (the first image) at a lane end location used to identify the visual elements of the lane, or change the materials of the visual elements of the lane. 
     It can be understood that a length, a width, and a location of a display area of the first image are all changeable. This embodiment provides only several possible examples. The first image may be displayed next to a speed identifier, may be displayed by overlapping the speed identifier, may fully occupy an upper part of an entire display panel, or the like. 
       FIG. 8 c    is a schematic diagram of a self-driving interface according to an embodiment of this application. As shown in  FIG. 8   c,  if the geographical location of the navigation destination of the first vehicle is located on a seaside, a first image (which may include, for example, a coconut tree and seawater) used to indicate the seaside may be displayed on the self-driving interface. 
       FIG. 8 d    is a schematic diagram of a self-driving interface according to an embodiment of this application. As shown in  FIG. 8   d,  if the geographical location of the navigation destination of the first vehicle is located in a mountain area, a first image (which may include, for example, a mountain) used to indicate the mountain area may be displayed on the self-driving interface. 
       FIG. 8 e    is a schematic diagram of a self-driving interface according to an embodiment of this application. As shown in  FIG. 8   e,  if the geographical location of the navigation destination of the first vehicle is located in a forest, a first image (which may include, for example, a plurality of trees) used to indicate the forest may be displayed on the self-driving interface. 
     The foregoing first images are merely examples, and do not constitute any limitation on this application. 
     In an embodiment, the first vehicle may further detect a third vehicle; obtain a geographical location of a navigation destination of the third vehicle; and display a second image based on the geographical location of the navigation destination of the third vehicle, where the second image is used to indicate a type of the geographical location of the navigation destination of the third vehicle. 
     In an embodiment of this application, if a driver of another vehicle (the third vehicle) is willing to disclose information about a destination (type) of the another vehicle, the type of a geographical location of the destination of the another vehicle may further be displayed on the self-driving interface. 
       FIG. 8 f    is a schematic diagram of a self-driving interface according to an embodiment of this application. As shown in  FIG. 8 f   , the first vehicle (the largest vehicle in the figure) can learn, by using the self-driving interface, that a vehicle ahead and a left-hand vehicle rather than a right-hand vehicle are going to a same type of destination (forest) as the first vehicle, because the vehicle ahead and the left-hand vehicle are identified by a special color and/or texture or a second image (including trees) indicating types of geographical locations of navigation destinations of the third vehicles is displayed around these vehicles. 
     In an embodiment of this application, the first vehicle may obtain the geographical location of the navigation destination of the first vehicle, and display the first image based on the geographical location, where the first image is used to indicate the type of the geographical location of the navigation destination of the first vehicle. The first vehicle may display a corresponding image on the self-driving interface based on a geographical location of a navigation destination, to enrich content of the self-driving interface. 
     In an embodiment of this application, the first vehicle may display an intersection stop indication on the self-driving interface when traveling to an intersection stop area. 
     In an embodiment, the first vehicle may detect that the first vehicle travels to the intersection stop area and display the intersection stop indication  901 . In an embodiment, the intersection stop area may be an area to which the first vehicle travels within a preset distance (for example, 20 m) from a red light intersection. 
     In an embodiment, the first vehicle may determine, based on an image or a video, that the first vehicle currently enters the intersection stop area, or may determine, based on the navigation information, that the first vehicle currently enters the intersection stop area. 
     In an embodiment, the first vehicle may obtain a status of a traffic light that is corresponding to the first vehicle and that is at a current intersection, and display a first intersection stop indication when the status of the traffic light is a red light or yellow light state. 
       FIG. 9 a    is a schematic diagram of a self-driving interface according to an embodiment of this application. As shown in  FIG. 9   a,  when the first vehicle travels to an intersection stop area, an intersection stopline is displayed on the self-driving interface. 
     It should be noted that, if the first vehicle is in a navigation state, a navigation indication  701  may further be displayed, and a part that is of the navigation indication  701  and that is beyond the intersection stopline is weakened for display. A weakening manner may be displaying only an outline of the navigation indication  701 , increasing transparency of the navigation indication  701 , or the like. This is not limited herein. 
     In an embodiment, the intersection stop indication includes the first intersection stop indication or a second intersection stop indication.

     In an embodiment of this application, when the vehicle head of the first vehicle exceeds the intersection stop indication  901 , display content of the first intersection stop indication  901  may be changed. For example, the intersection stop indication may be weakened for display. A weakening manner may be increasing transparency of the intersection stop indication or the like. This is not limited herein.

       FIG. 9 c    is a schematic diagram of a self-driving interface according to an embodiment of this application. As shown in  FIG. 9   c,  the first vehicle may detect that the first vehicle travels beyond an intersection stop area (the vehicle head of the first vehicle exceeds the intersection stop area), and correspondingly a weakened intersection stop indication and an enhanced navigation indication  701  (that is, displaying an outline of the complete navigation indication  701 , changing a color, or reducing transparency of the navigation indication  701 ) are displayed on the self-driving interface. 
     In another embodiment, the intersection stop indication includes a third intersection stop indication or a fourth intersection stop indication. The first vehicle may display the third intersection stop indication when detecting that the first vehicle travels to the intersection stop area and that a traffic light corresponding to the intersection stop area is a red light or a yellow light; and display the fourth intersection stop indication when detecting that the first vehicle travels to the intersection stop area and that a traffic light corresponding to the intersection stop area is a green light, where the third intersection stop indication is different from the fourth intersection stop indication. 
     In an embodiment of this application, the first vehicle displays the intersection stop indication when traveling to the intersection stop area, and information about the traffic light at the current intersection is further considered. Specifically, the first vehicle displays the third intersection stop indication when the first vehicle travels to the intersection stop area and the traffic light corresponding to the intersection stop area is a red light or a yellow light; and displays the fourth intersection stop indication when the first vehicle travels to the intersection stop area and the traffic light corresponding to the intersection stop area is a green light. For example, the fourth intersection indication may be an enhanced third intersection indication (that is, changing a color or reducing transparency of the navigation indication  701 ). 
     In an embodiment of this application, the first vehicle may display a vehicle alarm prompt on the self-driving interface based on a distance between a nearby vehicle and the current vehicle. 
     In an embodiment, the first vehicle may detect a fourth vehicle; and display a vehicle alarm prompt when a distance between the fourth vehicle and the first vehicle is less than a preset distance. 
     In an embodiment, the vehicle alarm prompt includes a first vehicle alarm prompt or a second vehicle alarm prompt. The first vehicle may display the first vehicle alarm prompt when the distance between the fourth vehicle and the first vehicle is the first distance; and display the second vehicle alarm prompt when the distance between the fourth vehicle and the first vehicle is the second distance, where the first distance is different from the second distance, and the first vehicle alarm prompt is different from the second vehicle alarm prompt. 
     In an embodiment of this application, the first vehicle may obtain distances between other vehicles and the first vehicle by using the distance sensor carried by the first vehicle, and display the vehicle alarm prompt after detecting that the distance between a vehicle (the fourth vehicle) and the first vehicle is less than the preset distance. 
     In an embodiment of this application, when another vehicle (the fourth vehicle) is around the first vehicle, an alarm alarm prompt (a danger prompt graphic) may be displayed on the self-driving interface by using a nearest point at which the current vehicle approaches the fourth vehicle as a center of a circle.  FIG. 10  is a schematic diagram of a self-driving interface according to an embodiment of this application. As shown in  FIG. 10 , the first vehicle may detect a fourth vehicle  1001 , and display a vehicle alarm prompt  1002  on the self-driving interface when a distance between the fourth vehicle  1001  and the first vehicle is less than the preset distance. 
     In an embodiment, colors of the alarm prompts may be different based on the distance between the fourth vehicle and the first vehicle. For example, the alarm prompt is displayed in red when the distance is particularly short, and is displayed in yellow when the distance is relatively short. 
     In an embodiment, when the distance between the fourth vehicle and the first vehicle continuously changes, the color of the danger prompt graphic may be changed gradually, instead of suddenly changing from red to yellow (or from yellow to red) when the corresponding threshold is exceeded. 
     In an embodiment of this application, the first vehicle may display a vehicle alarm prompt on the self-driving interface based on a distance between a nearby vehicle and the current vehicle, so that the driver can know a collision risk between the first vehicle and the another vehicle by using the alarm prompt displayed on the self-driving interface. 
     In an embodiment of this application, when the first vehicle changes from a turning state to a straight-driving state, or when the first vehicle changes from a straight-driving state to a turning state, the first vehicle may change a current display field of view of the self-driving interface. 
     Specifically,  FIG. 11 a    is a schematic diagram of a self-driving interface according to an embodiment of this application. As shown in  FIG. 11   a,  the first vehicle may display a first area based on a straight-driving state of the first vehicle.

     In this embodiment of this application, before turning right, the driver pays more attention to right-front information, to mainly determine whether there is a pedestrian. Therefore, the right-front scene area  1102  that is included in the second area and that is in the traveling direction of the first vehicle is greater than the right-front scene area  1101  included in the first area. 
       FIG. 11 c    is a schematic diagram of a self-driving interface according to an embodiment of this application. As shown in  FIG. 11 c   , the first vehicle may display a third area based on a right-turning state of the first vehicle.

     In an embodiment of this application, after turning left, the driver pays more attention to right-rear information, to mainly determine whether there is an incoming vehicle. Therefore, the right-rear scene area  1103  that is included in the third area and that is in the traveling direction of the first vehicle is greater than the right-rear scene area  1104  included in the fourth area. 
       FIG. 11 e    is a schematic diagram of a self-driving interface according to an embodiment of this application. As shown in  FIG. 11   e,  the first vehicle may display a fifth area based on a straight-driving state of the first vehicle.

     In an embodiment of this application, before turning left, the driver pays more attention to left-front information, to mainly determine whether there is a pedestrian. Therefore, the left-front scene area  1105  that is included in the fifth area and that is in the traveling direction of the first vehicle is greater than the left-front scene area  1106  included in the sixth area. 
       FIG. 11 g    is a schematic diagram of a self-driving interface according to an embodiment of this application. As shown in  FIG. 11 g   , the first vehicle may display a seventh area based on a left-turning state of the first vehicle. 
       FIG. 11 h    is a schematic diagram of a self-driving interface according to an embodiment of this application. As shown in  FIG. 11 h   , the first vehicle may display an eighth area based on a change of the first vehicle from the left-turning state to a straight-driving state, where a right-rear scene area  1107  that is included in the seventh area and that is in a traveling direction of the first vehicle is greater than a right-rear scene area  1108  included in the eighth area. 
     In an embodiment of this application, after turning left, the driver pays more attention to right-rear information, to mainly determine whether there is an incoming vehicle. Therefore, the right-rear scene area  1107  that is included in the seventh area and that is in the traveling direction of the first vehicle is greater than the right-rear scene area  1108  included in the eighth area. 
     It should be noted that the scene areas obtained through division in  FIG. 11 a    to  FIG. 11 h    are merely examples, and do not constitute any limitation on this application. 
     In other words, in this embodiment of this application, the first vehicle may change, based on an intersection turning area, a display field of view at which information is displayed on the display. Specifically, the turning area may be obtained by sensing whether a steering wheel rotates left or right. Alternatively, whether high-precision map navigation is enabled during vehicle traveling is determined and then whether the vehicle has traveled to an intersection requiring a left turn or a right turn is determined by using a navigation route. Alternatively, during vehicle traveling, only a high-precision map is enabled but no navigation is used, and the driver drives the vehicle instead; in this case, whether the vehicle needs to turn left or turn right is further determined by determining whether the vehicle travels at a preset distance close to an intersection and travels in a left-turn lane or a right-turn lane. 
     The field of view in this embodiment is a field of view at which information is displayed on the display. Specifically, a location of the current vehicle (e.g., the first vehicle) may be tracked by using a virtual camera, to present an object that can be seen in the field of view of the camera. Changing the display field of view means changing a location of the virtual camera relative to the current vehicle (x-axis, y-axis, and z-axis coordinates and angles in various directions), to present, on the display, a change of the object that can be seen in the field of view of the virtual camera. 
     For example, the current vehicle is used as an origin of coordinates, a direction facing a front side of the vehicle is a positive direction of a y-axis, and the traveling direction of the vehicle is a negative direction of the y-axis; and facing the vehicle, a right-hand side of the vehicle is a positive direction of an x-axis, and a left-hand side of the vehicle is a negative direction of the x-axis. The location of the virtual camera is above a z-axis, and is in a positive direction of the z-axis and in the positive direction of the y-axis. A field of view in this default state is referred to as a default field of view (referred to as a “default forward field of view” in the following embodiment). 
     It can be understood that a location of the origin and directions of various axes can be customized by a developer. 
     Turning right is used as an example. Before turning right, the driver pays more attention to right-front information, to mainly determine whether there is a pedestrian; and after the turning, the driver pays more attention to left-rear information, to mainly determine whether there is an incoming vehicle. If it is determined that the driver is about to turn right, the field of view of the virtual camera is changed from the default forward field of view to look right first (e.g., the virtual camera rotates right, and rotates from a direction facing the negative direction of the y-axis to the negative direction of the x-axis), and then the field of view of the virtual camera is changed to look left (e.g., the virtual camera rotates left, and rotates to the positive direction of the x-axis). After the turning ends and straight driving starts, the default forward field of view is restored (as shown in  FIG. 11 d   , the virtual camera faces the negative direction of the y-axis). 
     In an embodiment of this application, when the first vehicle changes from a turning state to a straight-driving state, or when the first vehicle changes from a straight-driving state to a turning state, the first vehicle may change a current display field of view, so that the driver can know information about an area that may have a safety risk when the vehicle turns. This improves driving safety. 
     In this embodiment of this application, the first vehicle may change the current display field of view of the self-driving interface based on a change of a traveling speed. 
     In an embodiment, the first vehicle may display a ninth area based on a first traveling speed of the first vehicle, and display a tenth area based on a second traveling speed of the first vehicle, where the ninth area and the tenth area are scene areas in which a traveling location of the first vehicle is located, the second traveling speed is higher than the first traveling speed, and a scene area included in the ninth area is greater than a scene area included in the tenth area. 
       FIG. 12 a    to  FIG. 12 d    are schematic diagrams of a self-driving interface according to an embodiment of this application. As shown in  FIG. 12 a    to  FIG. 12   d,  a case in which a vehicle speed is increasingly low is described from  FIG. 12 a    to  FIG. 12   d.  It can be learned that as the traveling speed of the first vehicle decreases, a scene area in which the traveling location of the first vehicle is located becomes smaller on the self-driving interface. 
     In an embodiment of this application, the first vehicle may make a road field of view displayed on the self-driving interface larger when the traveling speed of the vehicle increases, and correspondingly a road display range is larger. As the traveling speed of the vehicle decreases, more road information (buildings on both sides of a lane, pedestrians, roadside traffic facilities, and the like) displayed on a display panel becomes more obvious, and a road field of view displayed on the display panel becomes smaller, leading to a smaller road display range (the scene area in which the traveling location of the first vehicle is located). 
     For details about how to obtain through transformation the road field of view displayed on the self-driving interface, refer to the descriptions in the foregoing embodiment. Details are not described herein again. 
     As shown in  FIG. 12 a    to  FIG. 12   d,  from the case in which the vehicle speed is increasingly low, as described from  FIG. 12 a    to  FIG. 12   d,  it can be learned that the field of view is increasingly small. The field of view is large when the first vehicle travels at a high speed (a z-axis value of the location of the virtual camera is large), and the field of view is small when the first vehicle travels at a low speed (a z-axis value of the location of the virtual camera is small). It should be noted that the speed values in  FIG. 12 a    to  FIG. 12 d    are merely examples, and do not constitute any limitation on this application. 
     In addition, when the vehicle speed is relatively low, for example, when the vehicle travels in a street, the driver pays more attention to information about the surroundings of the vehicle, such as details of collision information. In this case, the field of view is closer to the vehicle, so that the driver focuses on information as the driver wants. As more road information (e.g., buildings on both sides of a lane, pedestrians, roadside traffic facilities, and the like) displayed on the display panel becomes more obvious, the road field of view displayed on the self-driving interface becomes smaller, leading to a smaller road display range. As shown in  FIG. 12 a    to  FIG. 12 d   , the traveling speed of the first vehicle is higher in  FIG. 12 a   , and then buildings on a roadside are weakened for display (e.g., through color lightening, transparency increase, and/or the like), while the traveling speed of the first vehicle is lower in  FIG. 12 d   , and then buildings on a roadside are enhanced for display (through color deepening, transparency decrease, and/or the like). 
     In an embodiment of this application, the first vehicle may display the ninth area based on the first traveling speed of the first vehicle, and display the tenth area based on the second traveling speed of the first vehicle, where the ninth area and the tenth area are the scene areas in which the traveling location of the first vehicle is located, the second traveling speed is higher than the first traveling speed, and the scene area included in the ninth area is greater than the scene area included in the tenth area. In the foregoing manner, when the traveling speed of the first vehicle is relatively high, a larger scene area may be displayed, so that the driver can know more road surface information when the traveling speed is relatively high. This improves driving safety. 
     In an embodiment of this application, the first vehicle may display, on the self-driving interface, a prompt indicating that a vehicle beside the first vehicle is inserted into the current traveling lane. 
     In an embodiment, the first vehicle may detect a fifth vehicle; display, when the fifth vehicle is located on a lane line of a lane in front of the traveling direction of the first vehicle, a third image corresponding to the fifth vehicle; and display, when the fifth vehicle travels to the lane in front of the traveling direction of the first vehicle, a fourth image corresponding to the fifth vehicle, where the third image is different from the fourth image. 
     In an embodiment of this application, when detecting that a vehicle (the fifth vehicle) is located on the lane line of the lane in front of the traveling direction of the first vehicle, the first vehicle determines that the fifth vehicle will overtake the first vehicle. 
     In an embodiment, the first vehicle may further determine, when the fifth vehicle is located on the lane line of the lane in front of the traveling direction of the first vehicle and a distance between the fifth vehicle and the first vehicle is less than a preset value, that the fifth vehicle will overtake the first vehicle. 
     In an embodiment, the first vehicle may process a photographed image or video, to determine that the fifth vehicle is located on the lane line of the lane in front of the traveling direction of the first vehicle. The first vehicle may send the photographed image or video to the server, so that the server determines that the fifth vehicle is located on the lane line of the lane in front of the traveling direction of the first vehicle, and then the first vehicle receives a determining result sent by the server. 
     In an embodiment of this application, for example, the fifth vehicle may be located behind the first vehicle (as shown in  FIG. 13 a   ). If detecting that the fifth vehicle is carrying out an overtake action, the first vehicle may display, on the self-driving interface by using a special color identifier (such as white), an image corresponding to the fifth vehicle (for a fifth vehicle  1301  shown in  FIG. 13 b   , in this case, the fifth vehicle  1301  is located on the lane line of the lane in front of the traveling direction of the first vehicle), indicating that the fifth vehicle hinders the speed of the first vehicle. 
     In an embodiment of this application, after detecting that the fifth vehicle completes overtaking, the first vehicle may change display content of the fifth vehicle. Specifically, the first vehicle may display, when the fifth vehicle travels to the lane in front of the traveling direction of the first vehicle (for a fifth vehicle  1301  shown in  FIG. 13 c   , in this case, the fifth vehicle  1301  is located on the lane in front of the traveling direction of the first vehicle, but is not located on the lane line), a fourth image corresponding to the fifth vehicle. A color and/or transparency of the fourth image may be different from that of the third image. 
     It should be noted that, the third image in  FIG. 13 b    and the fourth image in  FIG. 13 c    are merely examples. Display content of the third image and the fourth image is not limited in this application, provided that vehicles presented during overtaking and overtaking completion may be distinguished between each other.
