2. Description of the Related Art Conventionally, an automatic operation control device that executes automatic operation control is known. As an example of this type of automatic operation control apparatus, there is one described in Patent Document 1, for example.
In the automatic driving control method described in claim 1 of Patent Document 1, after it is determined that the control computer is ready to execute the automatic driving control of the vehicle, the user (driver) is notified of the fact, Thereafter, automatic operation control is engaged when a first input indicating that the user (driver) is ready is received.
As described above, the automatic operation control device described in Patent Document 1 requires the first input indicating that the user (driver) is ready in order to start the automatic operation control. Therefore, in the automatic driving control device described in Patent Document 1, the operation of the user (driver) at the start of the automatic driving control becomes complicated.
For drivers who do not want complicated operations, it is necessary to reduce the complexity of driver operations at the start of automatic driving control.
On the other hand, if the driver desires to perform manual driving, the driver does not want automatic driving control to be automatically started. That is, some drivers do not want automatic driving control to be automatically started.
In view of the above problems, the present invention provides a driver's request that the automatic driving control is desired to be started without the need for complicated operations, and a driver's request that the automatic driving control is not desired to be automatically started. An object of the present invention is to provide an automatic operation control device that can meet both requirements.
Specifically, an object of the present invention is to provide an automatic driving control device that can construct an appropriate user interface for each driver having different demands.
According to the present invention, in the automatic driving control device that executes the automatic driving control of the host vehicle,
A first determination unit that determines whether or not automatic operation control can be started;
Automatic operation control start trigger input section,
Trigger that starts automatic driving control when an automatic driving control start trigger is input by the driver to the automatic driving control start trigger input unit after the first determining unit determines that automatic driving control can be started De-engage mode,
An automatic engagement mode for automatically starting automatic driving control when the first determination unit determines that automatic driving control can be started;
There is provided an automatic operation control device comprising a switching unit for switching between the triggered engagement mode and the automatic engagement mode.
That is, in the automatic operation control device of the present invention, an automatic engagement mode for automatically starting automatic operation control is provided.
Therefore, in the automatic operation control device of the present invention, automatic operation control can be automatically started. That is, the automatic driving control can be started without the input of the automatic driving control start trigger by the driver.
As a result, in the automatic operation control device of the present invention, the automatic operation described in Patent Document 1 requires a first input indicating that the user (driver) is ready to start the automatic operation control. Compared with the control device, it is possible to reduce the complexity of the driver's operation at the start of the automatic driving control, and to improve the operability for starting the automatic driving control.
In view of this point, in the automatic driving control device of the present invention, a triggered engagement mode that starts automatic driving control when an automatic driving control start trigger is input by the driver after it is determined that automatic driving control can be started. However, it is provided separately from the automatic engagement mode. That is, in the triggered engagement mode, automatic driving control is not started unless an automatic driving control start trigger is input by the driver.
Furthermore, in the automatic operation control device of the present invention, a switching unit that switches between the triggered engagement mode and the automatic engagement mode is provided.
That is, in the automatic operation control device of the present invention, for example, when the driver does not want automatic operation control to be automatically started, the driver selects the triggered engagement mode via the switching unit. As a result, the automatic operation control is not automatically started, and the automatic operation control is started when the automatic operation control start trigger is input by the driver after it is determined that the automatic operation control can be started.
Therefore, in the automatic driving control device of the present invention, it is possible to suppress the possibility that the automatic driving control is automatically started even though the driver desires to execute the manual driving.
In other words, in the automatic driving control device of the present invention, the driver's request that the automatic driving control is desired to start even if the automatic driving control start trigger is not input by the driver, and the automatic driving control is automatically started. It is possible to meet both the demands of drivers who do not want to. As a result, it is possible to construct an appropriate user interface for each driver having different demands.
In other words, in the automatic driving control device of the present invention, the driver has a triggered engagement mode in which the driver determines the automatic driving control start timing and an automatic engagement mode in which the automatic driving control device determines the automatic driving control start timing. It can be switched and used properly.
In the automatic operation control device of the present invention, whether or not the automatic operation control in the first determination unit can be started when the automatic engagement mode is selected, compared to when the triggered engagement mode is selected. The criterion for judging whether or not may be set strictly.
That is, in the automatic operation control device of the present invention, it is easier to determine that the automatic operation control can be started when the triggered engagement mode is selected than when the automatic engagement mode is selected. Therefore, the time zone in which it is determined that the automatic driving control can be started is longer than when the automatic engagement mode is selected. As a result, the driver can have time to input the automatic driving control start trigger, and automatic driving control can be easily started as requested by the driver.
According to the present invention, both the request of a driver who desires automatic driving control to be started without the need for complicated operations and the request of a driver who does not want automatic driving control to be automatically started are met. Can do.

Hereinafter, a first embodiment of an automatic operation control device of the present invention will be described. FIG. 1 is a schematic configuration diagram of the automatic operation control apparatus according to the first embodiment.
In the example shown in FIG. 1, the automatic driving control device 100 is mounted on a host vehicle (not shown) such as a passenger car. The automatic driving control device 100 executes automatic driving control of the host vehicle. The automatic driving control means control in which driving operations such as acceleration, deceleration and steering of the own vehicle are executed without depending on the driving operation of the driver of the own vehicle.
The automatic driving control includes, for example, lane keeping support control. In the lane keeping assist control, a steered wheel (not shown) is steered automatically (that is, not by a driver's steering operation) so that the own vehicle does not depart from the traveling lane. That is, in the lane keeping assist control, for example, even when the driver does not perform the steering operation, the steering wheel is automatically steered so that the host vehicle travels along the traveling lane.
Further, the automatic operation control includes, for example, navigation control. In navigation control, for example, when there is no preceding vehicle ahead of the host vehicle, constant speed control is performed to drive the host vehicle at a constant speed at a preset speed, and there is a preceding vehicle ahead of the host vehicle. In addition, follow-up control is performed in which the vehicle speed of the host vehicle is adjusted in accordance with the inter-vehicle distance from the preceding vehicle.
In the example illustrated in FIG. 1, a comparison target used for determining whether to perform switching from automatic operation control to manual operation (specifically, the comparison target is quantified to be compared with a threshold value). However, if it is equal to or greater than a threshold value used for determining whether to perform switching from automatic driving control to manual driving, the automatic driving control device 100 switches the running automatic driving control to manual driving.
Specifically, for example, the operation amount of the steering operation, the accelerator operation, and the brake operation by the driver of the own vehicle during the automatic driving control (this operation amount includes the steering work amount) is equal to or greater than the threshold value. In this case, the automatic operation control device 100 switches the automatic operation control being executed to manual operation. The above-described steering work amount is described in detail in, for example, Japanese Patent Application Laid-Open No. 2015-063244.
Manual driving is, for example, a driving state in which the vehicle is driven mainly by the driving operation of the driver. The manual driving includes, for example, a driving state in which the vehicle travels based only on the driving operation of the driver. In addition, the manual driving includes a driving state in which driving operation support control is performed to assist the driving operation of the driver while mainly driving the driving operation of the driver.
The case where the driving operation support control is performed at the time of manual driving means that, for example, the driver performs any one of vehicle steering, accelerator operation, and braking operation, and the automatic driving control device 100 performs the main driving operation by the driver. A mode in which any of steering control, engine control, and brake control that has not been performed is included. Alternatively, a mode in which the operation amount is further added or subtracted by the driving operation support control with respect to the steering operation of the manual driving performed by the driver and the operation amount of the accelerator and the brake is also included.
In the example shown in FIG. 1, the automatic operation control device 100 includes an external sensor 1, a GPS (Global Positioning System) receiver 2, an internal sensor 3, a map database 4, a navigation system 5, an actuator 6, and an HMI (Human Machine Interface) 7. , A monitoring device 8, a shift lever 9, an auxiliary device U, and an ECU (electronic control unit) 10.

The external sensor 1 includes at least one of a camera, a radar (Radar), and a rider (LIDAR: Laser Imaging Detection and Ranging).
The camera is an imaging device that captures an external situation of the host vehicle. For example, the camera is provided on the back side of the windshield of the host vehicle. The camera may be a monocular camera or a stereo camera. The stereo camera has, for example, two imaging units arranged so as to reproduce binocular parallax. The imaging information of the stereo camera includes information in the depth direction. The camera outputs imaging information relating to the external situation of the host vehicle to the ECU 10. The camera may be an infrared camera as well as a visible light camera.
The radar detects obstacles outside the host vehicle using radio waves. The radio wave is, for example, a millimeter wave. The radar detects the obstacle by transmitting a radio wave to the surroundings of the host vehicle and receiving the radio wave reflected by the obstacle. For example, the radar can output the distance or direction to the obstacle as obstacle information regarding the obstacle. The radar outputs the detected obstacle information to the ECU 10. In addition, when performing sensor fusion, you may output the reception information of the reflected electromagnetic wave to ECU10.
The rider uses light to detect an obstacle outside the host vehicle. The rider transmits light around the vehicle and receives the light reflected by the obstacle, thereby measuring the distance to the reflection point and detecting the obstacle. For example, the rider can output the distance or direction to the obstacle as obstacle information. The rider outputs the detected obstacle information to the ECU 10. In addition, when performing sensor fusion, you may output the reception information of the reflected light to ECU10. The cameras, riders, and radars do not necessarily have to be provided in duplicate.
In the example shown in FIG. 1, the GPS receiver 2 receives signals from three or more GPS satellites, and acquires position information indicating the position of the host vehicle. The position information includes, for example, latitude and longitude. The GPS receiving unit 2 outputs the measured position information of the own vehicle to the ECU 10.
In another example, instead of the GPS receiving unit 2, other means that can specify the latitude and longitude in which the host vehicle exists may be used.
In the example shown in FIG. 1, the internal sensor 3 has information corresponding to the traveling state of the host vehicle and an operation amount of any one of a steering operation, an accelerator operation, and a brake operation by the driver of the host vehicle (this operation amount includes The steering work amount is also included). The internal sensor 3 includes at least one of a vehicle speed sensor, an acceleration sensor, and a yaw rate sensor in order to detect information corresponding to the traveling state of the host vehicle. The internal sensor 3 includes at least one of a steering sensor, an accelerator pedal sensor, and a brake pedal sensor in order to detect an operation amount.
The vehicle speed sensor is a detector that detects the speed of the host vehicle. As the vehicle speed sensor, for example, a wheel speed sensor that is provided for a wheel of the host vehicle or a drive shaft that rotates integrally with the wheel and detects the rotation speed of the wheel is used. The vehicle speed sensor outputs vehicle speed information (wheel speed information) including the speed of the host vehicle to the ECU 10.
The acceleration sensor is a detector that detects the acceleration of the host vehicle. The acceleration sensor includes, for example, a longitudinal acceleration sensor that detects acceleration in the longitudinal direction of the host vehicle and a lateral acceleration sensor that detects lateral acceleration of the host vehicle. The acceleration sensor outputs acceleration information including the acceleration of the host vehicle to the ECU 10.
The yaw rate sensor is a detector that detects the yaw rate (rotational angular velocity) around the vertical axis of the center of gravity of the host vehicle. For example, a gyro sensor is used as the yaw rate sensor. The yaw rate sensor outputs yaw rate information including the yaw rate of the host vehicle to the ECU 10.
The steering sensor is a detector that detects a steering operation amount of a steering operation on the steering wheel 30 (see FIG. 7) by a driver of the host vehicle, for example. The steering operation amount detected by the steering sensor is, for example, the steering angle of the steering wheel 30 or the steering torque with respect to the steering wheel 30. A steering sensor is provided with respect to the steering shaft of the own vehicle, for example. The steering sensor outputs information including the steering angle of the steering wheel 30 or the steering torque for the steering wheel 30 to the ECU 10.
The accelerator pedal sensor is a detector that detects the amount of depression of the accelerator pedal AP (see FIG. 6), for example. The amount of depression of the accelerator pedal AP is, for example, the position (pedal position) of the accelerator pedal AP with reference to a predetermined position. The predetermined position may be a fixed position or a position changed by a predetermined parameter. The accelerator pedal sensor is provided with respect to the shaft portion of the accelerator pedal AP of the host vehicle, for example. The accelerator pedal sensor outputs operation information corresponding to the depression amount of the accelerator pedal AP to the ECU 10.
The brake pedal sensor is a detector that detects the amount of depression of the brake pedal BP (see FIG. 6), for example. The amount of depression of the brake pedal BP is, for example, the position (pedal position) of the brake pedal BP with a predetermined position as a reference. The predetermined position may be a fixed position or a position changed by a predetermined parameter. The brake pedal sensor is provided for the brake pedal BP, for example. The brake pedal sensor may detect an operating force of the brake pedal BP (such as a pedaling force against the brake pedal BP or a pressure of the master cylinder). The brake pedal sensor outputs operation information corresponding to the depression amount or operation force of the brake pedal BP to the ECU 10.
In the example shown in FIG. 1, the map database 4 is a database provided with map information. The map database 4 is formed in, for example, an HDD (Hard Disk Drive) mounted on the host vehicle. The map information includes, for example, road position information, road shape information, and intersection and branch point position information. The road shape information includes, for example, a curve, a straight line type, a curve curvature, and the like. Further, when the automatic operation control device 100 uses the position information of a shielding structure such as a building or a wall or SLAM (Simultaneous Localization and Mapping) technology, the map information may include the output signal of the external sensor 1. Good.
In another example, the map database 4 may be stored in a computer of a facility such as an information processing center that can communicate with the host vehicle.
In the example shown in FIG. 1, the navigation system 5 is a device that guides the driver of the host vehicle to the destination set on the map by the driver of the host vehicle.
The navigation system 5 calculates a route traveled by the host vehicle based on the position information of the host vehicle measured by the GPS receiver 2 and the map information in the map database 4. The route may be, for example, a route that specifies a traveling lane in which the host vehicle travels in a section of multiple lanes. For example, the navigation system 5 calculates a target route from the position of the host vehicle to the destination, and notifies the driver of the target route by displaying the display 5a (see FIG. 8) and outputting sound from a speaker. For example, the navigation system 5 outputs information on the target route of the host vehicle to the ECU 10.
In the example shown in FIG. 1, the navigation system 5 uses the position information of the host vehicle measured by the GPS receiver 2 and the map information in the map database 4. In other examples, the navigation system 5 instead uses the position information of the own vehicle. Information stored in a computer of a facility such as an information processing center that can communicate with the vehicle may be used. Alternatively, part of the processing performed by the navigation system 5 may be performed by a facility computer.
In the example shown in FIG. 1, the actuator 6 is a device that executes traveling control of the host vehicle. The actuator 6 includes at least a throttle actuator, a brake actuator, and a steering actuator.
In the example shown in FIG. 1, the throttle actuator controls the amount of air supplied to the engine (throttle opening) in accordance with a control signal from the ECU 10 to control the driving force of the host vehicle.
In another example in which the host vehicle is an electric vehicle, the actuator 6 does not include a throttle actuator, the actuator 6 has a motor as a power source, and a control signal from the ECU 10 is input to the motor. The driving force is controlled.
The brake actuator controls the brake system according to a control signal from the ECU 10 and controls the braking force applied to the wheels of the host vehicle. As the brake system, for example, a hydraulic brake system can be used.
The steering actuator controls driving of an assist motor that controls steering torque in the electric power steering system in accordance with a control signal from the ECU 10. Thereby, the steering actuator controls the steering torque of the host vehicle.
In the example shown in FIG. 1, the HMI 7 is an interface for outputting and inputting information between a passenger (including a driver) of the own vehicle and the automatic driving control device 100. The HMI 7 includes, for example, a display panel for displaying image information to the occupant, a speaker for audio output, and an operation button or a touch panel for the occupant to perform an input operation. The HMI 7 may output information to the occupant using a wirelessly connected portable information terminal, or may accept an input operation by the occupant using the portable information terminal.
In the example shown in FIG. 1, the monitoring device 8 monitors the state of the driver. The monitoring device 8 can check the manual driving preparation state of the driver. Specifically, the monitoring device 8 can confirm whether or not the driver has completed preparations for starting manual operation, for example. Moreover, the monitoring apparatus 8 can confirm whether the driver has the intention to perform a manual driving | operation, for example.
The monitoring device 8 may be, for example, a camera that can image a driver, and is used, for example, to estimate the degree of eye opening and the line-of-sight direction of the driver. The monitoring device 8 may be, for example, a camera that captures the hand of the driver. For example, whether or not the driver is holding the steering wheel 30 (see FIG. 7) is obtained by image analysis. Alternatively, the monitoring device 8 may be a touch sensor (distortion sensor) that detects the strength of the force to grip the steering wheel 30 as described in, for example, Japanese Patent Application Laid-Open No. 11-091397.

Based on the above, a travel plan for the host vehicle is generated.
The travel plan is a trajectory that the host vehicle travels on the target route. The travel plan includes, for example, the speed, acceleration, deceleration, direction, steering angle, and the like of the host vehicle at each time.
The travel plan generation unit 13 generates a travel plan such that the host vehicle travels on a target route that satisfies standards such as safety, legal compliance, and travel efficiency. Furthermore, the travel plan generation unit 13 generates a travel plan for the host vehicle so as to avoid contact with the obstacle based on the situation of the obstacles around the host vehicle.
In the example illustrated in FIG. 1, the calculation unit 14 is based on the operation amount of the driver of the own vehicle during the automatic driving control acquired by the acquisition unit 11 (this operation amount includes the above-described steering work amount). A threshold value used for determining whether to perform switching from automatic operation control to manual operation is calculated.

For example, the determination unit 16b2 determines whether to switch from automatic driving control to manual driving based on the accelerator or brake operation amount of the driver of the host vehicle during the automatic driving control acquired by the acquiring unit 11. Judgment is performed.
When at least one of the M determination units 16b1, 16b2,..., 16bM determines that switching from automatic operation control to manual operation should be executed, the determination unit 16b It is determined that switching to manual operation should be executed.
As described above, each of the determination units 16a1, 16a2, ..., 16aN and the determination units 16b1, 16b2, ..., 16bM has basically different determination criteria.
In the example illustrated in FIG. 2, the control unit 16 (see FIGS. 1 and 2) includes a determination unit 16 c that comprehensively determines whether or not automatic operation control can be performed, and an automatic operation control unit that performs automatic operation control. 16d.
The determination unit 16c determines that the automatic operation control can be started when it is determined that the automatic operation control can be started in all of the N determination units 16a1, 16a2, ..., 16aN.
When the determination unit 16c determines that the automatic driving control can be started, the automatic driving control unit 16d starts the automatic driving control, as will be described in detail later.
On the other hand, when at least one of the M determination units 16b1, 16b2,..., 16bM determines that the switching from the automatic operation control to the manual operation is to be performed, the determination unit 16c performs the automatic operation control. It is determined that switching to manual operation should be executed, automatic operation control by the automatic operation control unit 16d is stopped, and manual operation by the driver is executed. That is, the determination that switching from the automatic operation control to the manual operation in any of the M determination units 16b1, 16b2,..., 16bM functions as a trigger for stopping the automatic operation control.
In the example illustrated in FIG. 2, the presenting unit 15 (see FIGS. 1 and 2) is provided with a control state notification unit 15 a that notifies the driver that automatic driving control is being performed.
When the automatic operation control is started, the fact that the automatic operation control is being executed is displayed on the display of the HMI 7, for example, by the control state notification unit 15a.
When switching from automatic operation control to manual operation is executed, the control state notification unit 15a indicates that, for example, automatic operation control is not being executed (that is, manual operation is being executed) Displayed on the display.
In the example illustrated in FIG. 2, the automatic operation control start trigger input unit 7 a is provided in the HMI 7, for example.
Furthermore, for example, the automatic operation control unit 16d has a triggered engagement mode and an automatic engagement mode.
Specifically, in the triggered engagement mode, when the automatic driving control start trigger is input to the automatic driving control start trigger input unit 7a by the driver after the determining unit 16a determines that the automatic driving control can be started. The automatic operation control is started by the automatic operation control unit 16d.
In the automatic engagement mode, when the determination unit 16a determines that the automatic operation control can be started, the automatic operation control unit 16d automatically starts the automatic operation control.
In the example shown in FIG. 2, the triggered engagement mode and the automatic engagement mode are switched according to the shift position of the shift lever 9. That is, in the example illustrated in FIG. 2, the shift lever 9 functions as a switching unit that switches between the triggered engagement mode and the automatic engagement mode.
In the example illustrated in FIG. 2, for example, when the shift lever 9 is disposed at the shift position “D (drive)”, the triggered engagement mode is set. When the shift lever 9 is disposed at the shift position “A (automatic)”, the automatic engagement mode is set. That is, in the example shown in FIG. 2, the shift position “A (automatic)” for the automatic engagement mode is provided, for example, at a position adjacent to the shift position “D (drive)” for the triggered engagement mode.
FIG. 3 is a flowchart for explaining the start of the automatic operation control in the triggered engagement mode and the start of the automatic operation control in the automatic engagement mode of the automatic operation control device of the first embodiment.
When the routine shown in FIG. 3 is started, first, in step S100, it is determined by the determination units 16a and 16c (see FIG. 2) whether or not the automatic operation control can be started. If YES, the process proceeds to step S101, and if NO, this routine is terminated.
In step S101, based on the shift position at which the shift lever 9 (see FIG. 2) is arranged, for example, by the determination unit 16c (see FIG. 2), whether it is the triggered engagement mode or the automatic engagement mode. Determined. When the shift lever 9 is disposed at the shift position “D (drive)”, the determination unit 16c determines that the trigger engagement mode is set, and the process proceeds to step S102. When the shift lever 9 is disposed at the shift position “A (automatic)”, the determination unit 16c determines that the automatic engagement mode is set, and the process proceeds to step S106.
In step S102, the driver is notified through the speaker and / or display panel of the HMI 7 (see FIGS. 1 and 2), for example, that automatic driving control can be started.
Next, in step S103, it is determined whether or not an automatic driving control start trigger is input to the automatic driving control start trigger input unit 7a (see FIG. 2) by the driver. If YES, the process proceeds to step S104, and if NO, this routine is terminated.
In step S104, automatic driving control is started by the automatic driving control unit 16d (see FIG. 2).
During execution of automatic operation control, an override determination is executed in step S105.
Specifically, in the override determination in step S105, whether or not there has been a driver's operation (specifically, a driver operation contrary to automatic driving control) during execution of automatic driving control, for example, the internal sensor 3 (see FIG. 1). For example, the ECU 10 (see FIG. 1) determines the amount of the driver's operation detected by the above (the operation amount includes the above-described steering work amount).
When there is an operation by the driver during execution of the automatic driving control, it is determined whether or not the operation amount of the driver is equal to or larger than the threshold calculated by the calculation unit 14 (see FIGS. 1 and 2). 2).
If the operation amount of the driver is greater than or equal to the threshold value, it is determined that the driver desires to perform switching from automatic driving control to manual driving, and automatic driving is performed by the control unit 16 (see FIGS. 1 and 2). Control is released and switching from automatic operation control to manual operation is executed.
On the other hand, when the operation amount of the driver is less than the threshold, it is determined that the driver desires to maintain the automatic driving control, and the automatic driving control by the automatic driving control unit 16d (see FIG. 2) is maintained.
In step S106, automatic driving control is automatically started by the automatic driving control unit 16d (see FIG. 2) without being operated by the driver.
Next, in step S107, the control state notification unit 15a (see FIG. 2) displays that the automatic operation control is being executed, for example, on the display of the HMI 7.
While the automatic operation control that has been automatically started is being executed, an override determination is executed in step S108.
Specifically, in the example shown in FIG. 2, after automatic operation control is automatically started in step S106 (see FIG. 3), switching from automatic operation control to manual operation is performed in step S108 (see FIG. 3). Whether to execute or not is determined by the determination unit 16b.
For example, in the determination unit 16b1, the automatic driving control is performed based on the steering operation amount of the driver of the host vehicle during the automatic driving control that is automatically started (this operation amount includes the above-described steering work amount). Whether to switch from manual operation to manual operation is determined.
For example, the determination unit 16b2 determines whether or not to switch from the automatic driving control to the manual driving based on the accelerator or brake operation amount of the driver of the host vehicle during the automatically started automatic driving control. Is executed.
That is, the determination unit 16b performs manual operation from the automatic driving control based on the operation amount of the driver of the own vehicle during the automatic driving control that is automatically started (this operation amount includes the steering work amount described above). A determination is made as to whether or not to switch to operation.
Further, in the example shown in FIG. 2, the adjustment unit 14 a that adjusts the threshold value used for determining whether or not the switching from the automatic operation control to the manual operation in the determination unit 16 b is performed is the calculation unit 14 (FIG. 1 and FIG. 2).
Specifically, before the predetermined period elapses after the automatic operation control is automatically started, the switching from the automatic operation control to the manual operation is more easily performed than after the elapse of the predetermined period. The threshold value used for determination in the determination unit 16b is adjusted by the adjustment unit 14a.
Specifically, the threshold value used for determination in the determination unit 16b is adjusted to the first threshold value by the adjustment unit 14a before a predetermined period of time elapses after automatic operation control is automatically started. After the elapse of the predetermined period, the threshold value used for determination in the determination unit 16b is adjusted to a second threshold value that is larger than the first threshold value by the adjustment unit 14a.
The second threshold value may be set as a fixed value in advance. Further, the second threshold value may not be set as a fixed value in advance, but may be set as a function that fluctuates according to the state of motion of the host vehicle such as the vehicle speed, or the state of the driver such as the arousal level. Alternatively, the second threshold value may be a value that is set in advance as a fixed value and then fluctuates in accordance with the state of motion of the host vehicle such as the vehicle speed or the state of the driver such as the arousal level. Specifically, the second threshold value is a threshold value used for determining whether or not there is an override. At least the second threshold value is a value obtained regardless of the start / end timing of the automatic operation control.
In the example shown in FIG. 2, the driver's operation amount (this operation amount includes the above-described steering work amount) exceeds the second threshold during a period in which the manual operation by the driver is being executed. The magnitude of the second threshold is set so that there is an instant.
In the example shown in FIG. 2 and FIG. 3 to which the automatic operation control device of the first embodiment is applied, for example, the threshold value used for the override determination in step S105 (see FIG. 3) and the step S108 (see FIG. 3) Although the second threshold value used for the override determination is set to an equal value, in another example to which the automatic operation control device of the first embodiment is applied, it is used instead for the override determination in step S108. The second threshold value can be set to a value smaller than the threshold value used for the override determination in step S105.
That is, in another example to which the automatic driving control device of the first embodiment is applied, the automatic driving control is started by the driver's intention even after a predetermined period has elapsed since the automatic driving control was automatically started. This makes it easier to switch from automatic operation control to manual operation.
FIG. 4 is a flowchart for explaining the override determination in step S108 of FIG.
When the routine shown in FIG. 4 is started, first, in step S200, whether or not there has been a driver's operation (specifically, a driver's operation contrary to automatic driving control) during execution of the automatically started automatic driving control. However, for example, the ECU 10 (see FIG. 1) determines the amount based on the driver's operation amount detected by the internal sensor 3 (see FIG. 1) (this operation amount includes the above-described steering work amount). If YES, the process proceeds to step S201, and if NO, the process proceeds to step S205.
In step S201, for example, the ECU 10 determines whether or not a predetermined period has elapsed since the automatic operation control was automatically started. If YES, the process proceeds to step S202, and if NO, the process proceeds to step S203.
In step S202, it is determined by the determination unit 16b (see FIG. 2) whether or not the driver's operation amount (this operation amount includes the above-described steering work amount) is equal to or greater than the first threshold value. If YES, it is determined that the driver wishes to execute switching from automatic driving control to manual driving, and the process proceeds to step S204. On the other hand, when the determination is NO, it is determined that the driver desires to maintain automatic driving control, and the process proceeds to step S205.
In step S203, the determination unit 16b (see FIG. 2) determines whether or not the driver's operation amount (this operation amount includes the above-described steering work amount) is equal to or greater than the second threshold value. If YES, it is determined that the driver wishes to execute switching from automatic driving control to manual driving, and the process proceeds to step S204. On the other hand, when the determination is NO, it is determined that the driver desires to maintain automatic driving control, and the process proceeds to step S205.
As described above, in the example shown in FIG. 4, the first threshold value in step S202 is set to a value smaller than the second threshold value in step S203.
That is, in the example shown in FIG. 4, the automatic operation control is automatically started before the predetermined period elapses before the predetermined period elapses after the automatic operation control is automatically started. The threshold value used for the determination in the determination unit 16b (see FIG. 2) is set so that the switching from the operation control to the manual operation is easy to be executed (that is, YES is easily determined in step S202). (See FIG. 2), the first threshold value in step S202 is set to a value smaller than the second threshold value in step S203.
In the example illustrated in FIG. 4, the predetermined period is set to 2 seconds, for example, and the first threshold value is set to, for example, one third of the second threshold value.
In step S204, automatic operation control is canceled and switching from automatic operation control to manual operation is executed.
In step S205, the automatic operation control by the automatic operation control unit 16d (see FIG. 2) is maintained.
In the example shown in FIG. 4, the first threshold value is fixed to a constant value after the automatic operation control is automatically started until the predetermined period elapses. When the first threshold value at the time when the driving control is automatically started is set to, for example, one third of the second threshold value, and a predetermined period elapses after the automatic driving control is automatically started. In addition, the value of the first threshold can be gradually changed so that the first threshold becomes equal to the second threshold.
As described above, in the example shown in FIG. 2 to which the automatic operation control device of the first embodiment is applied, for example, when the shift lever 9 is disposed at the shift position “D (drive)”, When the engagement mode is set and the shift lever 9 is disposed at the shift position “A (automatic)”, the automatic engagement mode is set.
That is, in the example shown in FIG. 2 to which the automatic operation control device of the first embodiment is applied, the mode switching between the triggered engagement mode and the automatic engagement mode can be easily performed without the driver visually observing the hand. In addition to being able to be performed, the shift position “A (automatic)” of the shift lever 9 indicates to the driver whether or not the automatic engagement mode can be automatically started even after the mode switching operation. Therefore, the driver can grasp whether or not the automatic engagement mode can automatically start the automatic operation control by simply touching the familiar shift lever 9 without having to visually observe the shift lever 9. it can.
That is, in the example shown in FIG. 2 to which the automatic operation control device of the first embodiment is applied, for example, whether or not the automatic engagement mode is able to automatically start the automatic operation control during the execution of the manual operation. It is possible to make the driver know whether or not the automatic engagement mode is capable of automatically starting the automatic operation control more safely than when the driver indicates it by means other than the shift lever 9. The driver who grasps that the automatic operation mode is capable of automatically starting the automatic operation control is switched from the automatic operation control to the manual operation after the automatic operation control is automatically started in step S106 (see FIG. 3). Can be prepared in advance.
In the example shown in FIG. 2 to which the automatic operation control apparatus of the first embodiment is applied, as described above, the driver does not need to visually observe the shift lever 9 and only touches the shift lever 9 that is familiar with the operation. It is possible to grasp whether the automatic engagement mode or the triggered engagement mode is set.
In another example to which the automatic operation control apparatus of the first embodiment is applied, instead, the display of the HMI 7 (see FIG. 1) indicates whether it is the automatic engagement mode or the triggered engagement mode. It is possible to notify the driver by displaying it, or notify the driver by sound output from the speaker of the HMI 7.
Specifically, in another example to which the automatic operation control device of the first embodiment is applied, the notification of the automatic engagement mode for the driver can be made more conspicuous than the notification of the triggered engagement mode for the driver. Specifically, when the automatic engagement mode or the triggered engagement mode is displayed on the display of the HMI 7, for example, the brightness of the color, the size of the drawing, and the type of color (prominent color) Or not), the presence or absence of blinking, the blinking speed, and the like can be made different between the automatic engagement mode and the triggered engagement mode. Furthermore, the number of means for notifying the driver whether the automatic engagement mode or the triggered engagement mode is set can be made different between the automatic engagement mode and the triggered engagement mode. Specifically, the driver is informed of the triggered engagement mode only by displaying the display of the HMI7, and the automatic engagement mode is displayed on the display of the HMI7, the sound output of the speaker of the HMI7, and the steering. The driver can be notified by vibration of the wheel 30 (see FIG. 7) or the like.
In the example shown in FIG. 3 to which the automatic driving control apparatus of the first embodiment is applied, the automatic driving control start trigger does not need to be input by the driver when the automatic engagement mode is set, and the automatic driving control is performed in step S106. Operation control starts automatically.
For this reason, in the example shown in FIG. 3 to which the automatic driving control device of the first embodiment is applied, for example, when the driver has a margin such as when the host vehicle is traveling straight or stopped (that is, the driver) Even when there is no room for inputting the automatic operation control start trigger), the automatic operation control can be started. As a result, it is possible to meet the driver's desire to rely on automatic driving control.
Further, in the example shown in FIG. 3 to which the automatic operation control device of the first embodiment is applied, there is no need to input an automatic operation control start trigger when the automatic engagement mode is set. It is possible to eliminate the need for the driver to continue to check the determination result of step S100 in order to input the start trigger.
In other words, since the automatic operation control apparatus of the first embodiment is provided with the automatic engagement mode for automatically starting the automatic operation control, even if there is no input of the automatic operation control start trigger by the driver, the step is performed. In S106 (see FIG. 3), the automatic operation control can be automatically started.
In the automatic driving control device of the first embodiment, when it is determined in step S100 (see FIG. 3) that automatic driving control can be started, an automatic driving control start trigger is input by the driver, step S104. A triggered engagement mode for starting automatic operation control in (see FIG. 3) is provided separately from the automatic engagement mode. That is, in the triggered engagement mode, automatic driving control is not started unless an automatic driving control start trigger is input by the driver.
Further, in the automatic operation control device of the first embodiment, a shift lever 9 (see FIGS. 1 and 2) that functions as a switching unit that switches between a triggered engagement mode and an automatic engagement mode is provided.
That is, in the automatic operation control apparatus of the first embodiment, for example, when the driver does not want automatic operation control to be automatically started, the shift lever 9 is moved to the shift position “D (drive)” by the driver. Placed and the triggered engagement mode is selected. As a result, the automatic operation control is not automatically started, and after it is determined in step S100 that the automatic operation control can be started, the automatic operation control start trigger is input by the driver to the automatic operation control start trigger input unit 7a (see FIG. 2). ), Automatic operation control is started in step S104.
Therefore, in the automatic driving control device of the first embodiment, it is possible to suppress the possibility that the automatic driving control is automatically started even though the driver desires to execute the manual driving. In other words, both a request from a driver who wants automatic driving control to start even if there is no automatic driving control start trigger input by the driver, and a request from a driver who does not want automatic driving control to start automatically Can respond. That is, the driver can selectively use the triggered engagement mode in which the driver determines the automatic driving control start timing and the automatic engagement mode in which the automatic driving control device determines the automatic driving control start timing.
When the automatic operation control is automatically started in step S106 (see FIG. 3) even though the driver desires to execute the manual operation, the driver executes the switching from the automatic operation control to the manual operation. I hope. At this time, if it is difficult to switch from automatic operation control to manual operation, there is a situation where the driver cannot execute manual operation even though the driver desires to perform manual operation. It is not preferable.
In view of this point, in the automatic operation control device of the first embodiment, the driver's operation amount (this operation amount is described above) before a predetermined period has elapsed since automatic operation control was automatically started in step S106. Step S204 (see FIG. 4), when it is determined in step S202 (refer to FIG. 4) that the steering work amount is also greater than or equal to a first threshold value smaller than a second threshold value that is a threshold value after the predetermined period. In (see FIG. 4), switching from automatic operation control to manual operation is executed.
That is, in the automatic operation control device of the first embodiment, before the predetermined period elapses after the automatic operation control is automatically started in step S106, the driver operates the smaller operation amount (after the predetermined period elapses). The operation amount includes the above-described steering work amount), and switching from the automatic operation control to the manual operation can be executed. That is, before the predetermined period elapses after the automatic operation control is automatically started in step S106, switching from the automatic operation control to the manual operation is more easily performed than after the elapse of the predetermined period.
Therefore, in the automatic operation control apparatus of the first embodiment, before the predetermined period elapses after the automatic operation control is automatically started in step S106, it is easier, that is, quicker than after the elapse of the predetermined period. In addition, the driver can perform manual operation. As a result, it is possible to reduce the possibility of a situation in which the driver cannot execute the manual operation even though the driver desires to execute the manual operation.
Furthermore, in the example shown in FIG. 2 and FIG. 3 to which the automatic driving control device of the first embodiment is applied, it is indicated in step S107 (see FIG. 3) that automatic driving control is automatically started in step S106 (see FIG. 3). 3), a control state notification unit 15a (see FIG. 2) is provided that functions as a notification device that notifies the driver. Therefore, in the example shown in FIG. 2 and FIG. 3 to which the automatic driving control device of the first embodiment is applied, it is possible to reduce the possibility that the driver does not notice that the automatic driving control is automatically started.
In another example to which the automatic driving control device of the first embodiment is applied, instead, a control state notification unit 15a that functions as a notification device that notifies the driver that automatic driving control has been automatically started (see FIG. 2) can be omitted.
In the example shown in FIG. 2 and FIG. 4 to which the automatic operation control device of the first embodiment is applied, the threshold value used for the determination in steps S202 and S203 (see FIG. 4) by the determination unit 16b (see FIG. 2) is A control state notification unit 15a (see FIG. 2) that functions as a notification device that notifies the driver that the change has occurred before and after the lapse of the predetermined period by being adjusted by the adjustment unit 14a (see FIG. 2). ) Is provided.
That is, in the example shown in FIGS. 2 and 4 to which the automatic operation control device of the first embodiment is applied, a predetermined period elapses after the automatic operation control is automatically started in step S106 (see FIG. 3). Before, the driver is informed that the size of the threshold used to determine whether to perform switching from automatic driving control to manual driving is smaller than after the lapse of the predetermined period, Even when the automatic driving control is automatically started against the driver's intention, it is possible to give the driver a sense of security that the switching from the automatic driving control to the manual driving can be easily performed within the predetermined period.
As means for notifying that the threshold value before the predetermined period has elapsed and the threshold value after the predetermined period have elapsed, for example, sound, visual display, vibration of the steering wheel 30 (see FIG. 7), or the like is used. it can.
In another example to which the automatic driving control device of the first embodiment is applied, the control state notification unit 15a that functions as a notification device that notifies the driver of a change in threshold value can be omitted instead.
In the example shown in FIGS. 1, 2 and 4 to which the automatic operation control device of the first embodiment is applied, the state of the driver is monitored by the monitoring device 8 (see FIG. 1). Furthermore, the length of the predetermined period of step S201 (see FIG. 4) is changed by the adjusting unit 14a (see FIG. 2) according to the state of the driver monitored by the monitoring device 8.
Specifically, in the example shown in FIGS. 1, 2, and 4 to which the automatic operation control device of the first embodiment is applied, for example, the driver may not yet complete preparations for starting manual operation. When confirmed by the monitoring device 8, the length of the predetermined period that facilitates switching from automatic operation control to manual operation is extended. On the other hand, for example, when the monitoring device 8 confirms that the driver does not intend to perform manual driving, the length of the predetermined period during which switching from automatic driving control to manual driving is easily performed is shortened. The
Therefore, in the example shown in FIGS. 1, 2, and 4 to which the automatic driving control device of the first embodiment is applied, there is a risk that switching from automatic driving control to manual driving will be executed against the driver's intention, Further, it is possible to reduce the possibility that the automatic driving control is continued against the driver's intention as compared with the case where the length of the predetermined period is not changed.
In another example to which the automatic operation control device of the first embodiment is applied, the monitoring device 8 can be omitted or the length of the predetermined period can be made unchanged.
In the example shown in FIG. 2 and FIG. 3 to which the automatic driving control device of the first embodiment is applied, when the automatic engagement mode is selected by the driver and when the triggered engagement mode is selected by the driver. In both cases, it is determined by the determination units 16a and 16c (see FIG. 2) whether or not the automatic operation control can be started in step 100 (see FIG. 3). In other words, the criterion for determining whether or not automatic driving control can be started when the automatic engagement mode is selected is equal to the criterion for determining whether or not automatic driving control can be started when the triggered engagement mode is selected. Is set.
In another example to which the automatic operation control device of the first embodiment is applied, instead, the determination criterion for determining whether or not the automatic operation control can be started when the automatic engagement mode is selected is the trigger engagement mode. It is set more strictly than the criterion for determining whether or not automatic operation control can be started at the time of selection. That is, in another example to which the automatic operation control device of the first embodiment is applied, it is determined that the automatic operation control can be started when the automatic engagement mode is selected, compared to when the triggered engagement mode is selected. 16c is difficult to determine. In other words, when the triggered engagement mode is selected, it is easier for the determination units 16a and 16c to determine that the automatic operation control can be started than when the automatic engagement mode is selected.
Therefore, in another example to which the automatic operation control device of the first embodiment is applied, the driver selects the triggered engagement mode even in an operation situation where the automatic operation control is not started when the automatic engagement mode is selected. By inputting the automatic operation control start trigger via the automatic operation control start trigger input unit 7a (see FIG. 2), the automatic operation control can be started by the automatic operation control unit 16d (see FIG. 2).
In another example to which the automatic operation control device of the first embodiment is applied, it is not determined that the automatic operation control can be started when the automatic engagement mode is selected, but the triggered engagement mode is selected. Sometimes, when the automatic engagement mode is selected by the driver in the driving situation where it is determined that the automatic driving control can be started, the driver automatically uses the automatic driving control start trigger input unit 7a (see FIG. 2). When an operation control start trigger is input, the automatic operation control unit 16d (see FIG. 2) can also start automatic operation control.
Furthermore, in another example to which the automatic operation control device of the first embodiment is applied, it is easier to determine that the automatic operation control can be started when the triggered engagement mode is selected than when the automatic engagement mode is selected. Therefore, the time zone in which it is determined that the automatic operation control can be started is longer than when the automatic engagement mode is selected.
As a result, in another example to which the automatic driving control apparatus of the first embodiment is applied, the driver can have a time margin for inputting the automatic driving control start trigger, and in step S104 (see FIG. 3) Automatic operation control can be easily started as requested by the driver.
If it is easily determined that the automatic driving control can be started when the automatic engagement mode is selected, for example, the behavior of the host vehicle such as when the host vehicle is traveling on a road with a large curvature. As a result, the driver starts to feel uneasy (incorrect impression) that the behavior of the vehicle is likely to be disturbed when the automatic driving control is automatically started. There is a risk of having.
In view of this point, in another example to which the automatic operation control device of the first embodiment is applied, as described above, when the automatic engagement mode is selected, the automatic operation control is started more than when the triggered engagement mode is selected. It is difficult to determine that it is possible.
Therefore, in another example to which the automatic driving control device of the first embodiment is applied, it is possible to suppress the possibility that the behavior of the host vehicle is disturbed when the automatic driving control is automatically started. When the vehicle is automatically started, it is possible to reduce the possibility that the driver has anxiety (incorrect impression) that the behavior of the vehicle is likely to be disturbed.
In the example shown in FIG. 1 and FIG. 2 to which the automatic operation control device of the first embodiment is applied, as described above, the shift position “D (drive)” of the shift lever 9 corresponds to the triggered engagement mode. Although the shift position “A (automatic)” of the shift lever 9 corresponds to the automatic engagement mode, in another example to which the automatic operation control device of the first embodiment is applied, instead, for example, the shift position “ A shift position “T (trigger)” is provided at a position adjacent to “A (automatic)” or shift position “D (drive)”, and automatic operation control is turned off (invalid) for the shift position “D (drive)” of the shift lever 9. The shift position “A (automatic)” of the shift lever 9 is made to correspond to the automatic engagement mode, and the shift position “T (trigger)” of the shift lever 9 is set to the triggered engagement mode. It may correspond to de.
The determination of suspension (cancellation) of automatic driving control is not limited to comparing the amount of driver operation with a threshold value as described in the example above, but based on the presence or absence of driver operation itself. It is also possible to determine whether to cancel (cancel). An example of a driver operation that is not a driver operation amount is, for example, a winker operation by a driver.
In the embodiment of the invention related to the present invention, if the predetermined period of step S201 (see FIG. 4) has elapsed after the automatic driving control is started, it is determined even if the driver performs the blinker operation. The unit 16b (see FIG. 2) does not determine that switching from automatic operation control to manual operation should be performed. On the other hand, if the predetermined period has not elapsed, the determination unit 16b determines that switching from the automatic operation control to the manual operation should be executed when the winker operation is performed by the driver.
