Crowdsourced driver feedback

Methods, systems, and devices for wireless communications are described. A human user, such as a pedestrian, cyclist, or driver, may provide a feedback message to a vehicle whose behavior they observe. The feedback message and the recipient may be manually identified by the human user or may be suggested by the system or device. The feedback message may be broadcast and filtered by vehicles within the broadcast radius based on a vehicle identifier. A vehicle that receives the feedback message may discard the feedback message if it applies to another vehicle or may take responsive action if the feedback message applies to the vehicle. For example, the recipient vehicle may display the feedback message, store the feedback message to support related analysis, or relay the feedback message to other vehicles or network devices.

BACKGROUND

The following relates generally to wireless communications, and more specifically to crowdsourced driver feedback.

Fully autonomous driving, which may leverage wireless communications systems, is an ongoing area of research. Fully autonomous driving may, however, be at least some time away from marketplace acceptance and saturation, thus, many vehicles may be driven at least in part by humans for at least some time.

SUMMARY

The described techniques relate to improved methods, systems, devices, and apparatuses that support crowdsourced driver feedback. Generally, the described techniques provide for an application by which a human user can provide a feedback message to a driver whose behavior they observe. The feedback message could be a simple message (e.g., thumbs up, thumbs down) or a more complex message (e.g., providing information about the behavior that prompted the feedback). The feedback message could be broadcast within a vicinity of the transmitting device, and recipient devices could filter feedback based on vehicle identifiers to act on relevant feedback messages and discard irrelevant feedback messages.

DETAILED DESCRIPTION

Fully autonomous driving may be at least some time (e.g., years) away from marketplace acceptance and saturation, so many vehicles will likely still be driven at least in part by humans for some time. There is currently not a convenient and reliable mechanism for humans (e.g., pedestrians, cyclists, other motorists) to provide feedback (positive or negative) to human drivers they observe.

Autonomous vehicles based on vehicle-supported wireless communications (e.g., vehicle-to-vehicle (V2V) and vehicle-to-anything (V2X) communications) are two technologies that are actively being integrated into future vehicles. During the transition period to fully-autonomous vehicles, human-driven vehicles and partially self-driving vehicles may be present together on roadways for some time. However, vehicle-supported wireless communications technologies may see widespread deployment ahead of full autonomous driving. Thus, leveraging vehicle-supported wireless communications to help improve the behavior of humans that are operating vehicles may help ease potential problems with this transitionary period.

The present techniques provide ways for users to provide feedback messages to a driver whose behavior they observe. Examples of the feedback message may include a symbol or other brief message such as a thumbs up or thumbs down. In some cases, the feedback message may include a reason code (e.g., a code mapped to a particular vehicle operation) or information that details the observed behavior. In some cases, the feedback message may be broadcast within a vicinity of a device transmitting the feedback message. In some cases, recipient devices may filter received feedback messages based on certain criteria. In some cases, recipient devices may take action on relevant feedback messages. In some cases, recipient devices may discard irrelevant feedback messages. The certain criteria may include a vehicle identifier included in the feedback message, or device information associated with the device sending the feedback message, or user profile information associated with a user sending the feedback message, or privacy issues associated with anonymity of the user sending the feedback message, etc., or any combination thereof.

An application in a vehicle may take one or more of a wide range of possible actions upon receipt of a feedback message for the vehicle. Such actions include displaying the feedback message to an occupant of the vehicle, or storing the feedback message for compilation with prior feedback messages for the driver or vehicle to develop a composite score (which may also be displayed), or storing the feedback message to the cloud, or relaying the feedback message or composite score to nearby vehicles as guidance (e.g., a warning or an alert) about the vehicle, or taking control of the vehicle (e.g., adjusting speed, pulling over, or disabling the vehicle, etc.), or relaying the feedback message or composite score to other entities (e.g., a corporate owner for fleet vehicles, parents, owner of the vehicle, insurance companies, etc.), or any combination thereof. The action of a recipient application may depend on severity/content of the feedback message. The recipient application may also account for multiple feedback messages received within a threshold amount of time or account for a profile of the sending application (e.g., whether the sending application (user) only sends negative feedback) when determining a responsive action. The recipient application may also seek to protect the anonymity of a vehicle, device, or user sending feedback (e.g., delay display of feedback messages) when no other vehicles or users are detected to be within some vicinity of the vehicle receiving the feedback.

In some examples, a transmitting application (e.g., in a sending vehicle or smartphone device) may support manual selection of one or more target vehicles and of a related feedback message by a user. In some cases, a transmitting application also may suggest feedback messages or one or more target vehicles based on sensor data (e.g., included in the transmitting vehicle) and related observations of nearby vehicles including the one or more target vehicles. In some cases, a transmitting application may be configured to mitigate abuse of feedback messages (e.g., restricting excessive messages by a user).

The transmitting application may enable a user to provide feedback for positive vehicle operations (e.g., letting a pedestrian or bicyclist cross the street, leaving space for another vehicle to change lanes or merge onto the highway) and for negative vehicle operations (e.g., passing on the right, weaving in and out of traffic, tailgating, not properly signaling path changes, cell phone use while driving, personal grooming while driving, reading map/newspaper while driving).

In some examples, an occupant in vehicle A may observe vehicle B make an unsafe lane change. The occupant may select vehicle B as a potential recipient of a feedback message. The occupant of vehicle A may configure a feedback message with a thumbs-down and transmit the feedback message to vehicle B. The feedback message may be broadcasted from vehicle A to one or more vehicles within some vicinity of vehicle A, including vehicle B. A descriptor included in the feedback message may identify vehicle B. Accordingly, vehicle B may receive the message, identify the descriptor, and determine that the feedback message is intended for vehicle B. In some examples, vehicle B may display the feedback message on a display in vehicle B. Vehicle C, another vehicle in the vicinity, may receive the message, identify the descriptor, and determine the feedback message is not intended for vehicle C. Accordingly, vehicle C may discard the feedback message.

Aspects of the disclosure are initially described in the context of a wireless communications system. Aspects of the disclosure are further illustrated by vehicles employing wireless communications systems. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to crowdsourced driver feedback.

In some cases, a UE115may also be able to communicate directly with other UEs115(e.g., using a peer-to-peer (P2P), device-to-device (D2D) protocol, V2X protocol, or V2V protocol). One or more of a group of UEs115utilizing direct UE-to-UE communications may be within the geographic coverage area110of a base station105. Other UEs115in such a group may be outside the geographic coverage area110of a base station105, or be otherwise unable to receive transmissions from a base station105. In some cases, groups of UEs115communicating via direct UE-to-UE communications may utilize a one-to-many (1:M) (broadcast) system in which each UE115transmits to every other UE115in the group. In some cases, a base station105facilitates the scheduling of resources for direct UE-to-UE communications. In other cases, direct UE-to-UE communications are carried out between UEs115without the involvement of a base station105.

In some examples, a UE115may be included in a vehicle (e.g., a vehicle computing device and one or more interfaces such as one or more displays, one or more microphones, one or more speakers, etc.). In some cases, a first UE115(e.g., a smartphone or a wireless device integrated in a first vehicle) may receive an input from a user. In some cases, the first UE115may identify a second UE115(e.g., a computer integrated in a second vehicle) based on the input. In some cases, the first UE115may generate a feedback message for the second UE115based on the input. In some cases, the first UE115may transmit the feedback message to the second UE115based at least in part on identifying the motor vehicle and the feedback message.

FIG. 2illustrates an example of a system200that supports crowdsourced driver feedback in accordance with aspects of the present disclosure. In some examples, system200may implement aspects of wireless communication system100. In some cases, system200may include at least one vehicle and at least one transmitting device associated with a feedback message. The exemplary components of system200may include hardware, or software, or firmware, or any combination thereof, to implement communication between each component. In the illustrated example, the components of system200may include a base station105-a, a UE115-aoperated by a user215, a vehicle205(e.g., a first vehicle), and a vehicle210(e.g., a second vehicle). Non-limiting examples of vehicle type for vehicle205or vehicle210may include coupe, sedan, hatchback, wagon, crossover, sport utility vehicle, truck, van, minivan, sports car, bus, shuttle, semi-trailer truck, limousine, motorcycle.

As shown, vehicle205and vehicle210may each include a wireless communication device that enables vehicle205and vehicle210to communicate with each other, or with base station105-a, or with UE115-a. It is noted that reference to vehicle205or vehicle210may refer to a wireless communication device integrated into vehicle205or vehicle210.

In some cases, vehicle205and vehicle210may be configured to communicate using wireless communication protocols. The wireless communication protocols may be implemented in at least one of a wireless local area network (WLAN), a cellular network (e.g., LTE, 5G, etc.), or any combination thereof. In some cases, vehicle205and vehicle210may communicate with each other over a vehicular ad-hoc network.

In some cases, vehicle205and vehicle210may support wireless communications via one or more protocols (e.g., V2X, V2V, vehicle-to-infrastructure (V2I)), which may enable vehicle205to communicate with vehicle210. V2I communication protocols may enable vehicle205or vehicle210to communicate with any combination of traffic lights, traffic signs, lane and road markings, parking structures, parking meters, buildings, etc. In some cases, V2X includes vehicle-to-network (V2N) communication protocols that enable vehicle205or vehicle210to communicate with wireless or cellular infrastructure (e.g., base station105-a), to the cloud, to the Internet, etc. In some cases, V2X may include vehicle-to-pedestrian (V2P) communication protocols that enable vehicle205or vehicle210to communicate with devices of pedestrians such as UE115-aof user215. In some cases, a pedestrian may include at least one of a person on foot (e.g., person walking, jogging, sitting, standing with a wireless device), a cyclist (e.g., wireless device integrated in a bicycle), person in a wheelchair (e.g., wireless device integrated in a wheelchair), an animal (e.g., wireless device integrated in the collar of a service animal), etc. Though certain examples may be described herein in terms of vehicle-to-vehicle communications, it is to be understood that the techniques described herein may also be applied to support feedback messages for vehicles from non-vehicle sources. For example, a feedback message for a vehicle may be generated, transmitted to the vehicle, or both by any type of device that supports wireless communications with the vehicle, regardless of whether the other device is also included in or associated with a vehicle (e.g., the other device may be any type of UE115, base station105, or other wireless device).

In some cases, system200may enable a user to provide feedback to a vehicle when the user observes the vehicle performing a vehicle operation. In some cases, system200may enable a device to autonomously (without user input) provide feedback to a vehicle when the device autonomously detects the vehicle performing a vehicle operation. In one example, system200may to prompt an occupant of a motor vehicle with a candidate complement to send to another motor vehicle. In another example, user215may observe vehicle205not stop for a pedestrian (e.g., user215) at a marked crosswalk. Accordingly, user215may use UE115-ato identify vehicle205, enter information (e.g., user input) regarding vehicle205not stopping at the crosswalk, generate a feedback message based on the entered information (e.g., the feedback message indicating the failure to stop), and transmit the feedback message to vehicle205. In some cases, the feedback message may be transmitted from device115-adirectly to vehicle205(e.g., via a wireless communications link that is directly between device115-aand vehicle205). Additionally or alternatively, the feedback message may be transmitted from device115-ato base station105-a, and from base station105-ato vehicle205. Although the exemplary illustration does not show direct communication between UE115-aand base station105-a, it is understood that UE115-amay transmit data to and/or receive data from base station105-a.

In another example, an occupant of vehicle210may observe vehicle205change lanes without signaling and cutting off another vehicle. Accordingly, an occupant of vehicle210may identify vehicle205, enter information (e.g., user input) in an interface of vehicle210(e.g., user interface displayed on a display of vehicle210integrated with the wireless communication device of vehicle210), generate a feedback message based on the entered information (e.g., the feedback message indicating improper lane change), and transmit the feedback message to vehicle205. In some cases, the feedback message may be transmitted from vehicle210directly to vehicle205(e.g., via a wireless communications link that is directly between device115-aand vehicle205). Additionally or alternatively, the feedback message may be transmitted from vehicle210to base station105-a, and from base station105-ato vehicle205.

In another example, vehicle210(e.g., a computing device of vehicle210integrated with the wireless communication device of vehicle210) may detect vehicle205speeding in a school zone when the school zone lights are flashing. For example, vehicle210may detect that the lights of a school zone light system are flashing (e.g., via a sensor detecting the lights are flashing, the school zone light system communicating with vehicle210, etc.), may detect vehicle205in a school zone associated with the school zone light system (e.g., vehicle210determines its own location and determines a relative position of vehicle205based on a heading of vehicle205and a heading of vehicle210), and may determine a speed of vehicle210(e.g., a sensor of vehicle210sensing a speed of vehicle205relative to vehicle210, vehicle205communicating its speed to vehicle210, etc.). Based on the autonomous detections of vehicle210, vehicle210may determine that vehicle205is speeding in a school zone. Accordingly, vehicle210may autonomously generate a feedback message based on the determination (e.g., the feedback message indicating that vehicle205is speeding in a school zone), and autonomously transmit the feedback message to vehicle205. In some cases, vehicle210may display information regarding the vehicle205speeding in the school zone and prompt an occupant of vehicle210for permission to transmit the feedback message.

FIG. 3illustrates an example of a system300that supports crowdsourced driver feedback in accordance with aspects of the present disclosure. In some examples, system300may implement aspects of wireless communication system100. In some examples, system300may include motor vehicle305, UE115, and base station105. In the illustrated example, motor vehicle305may include interface310, transceiver315, at least one antenna320, storage325, communication manager330, at least one processor335, memory340, and at least one sensor345. Examples of sensor345may include at least one of one or more image sensors, one or more motion sensors, one or more proximity sensor, one or more gyroscope sensors, one or more accelerometers, one or more radar sensors, one or more light detection and ranging (LIDAR) sensors, one or more global positioning system (GPS) sensors, one or more local positioning system (LPS) sensors, one or more ultrasonic sensors, or any combination thereof.

In some cases, motor vehicle305may include a wireless device. It is noted that reference to motor vehicle305performing an operation may include motor vehicle305performing an operation in conjunction with the wireless device of motor vehicle305. In some examples, the wireless device of motor vehicle305may include at least one of hardware (e.g., customized processors, customized memory, customized storage), or firmware (e.g., customized drivers that enable motor vehicle305to interface with hardware of the wireless device), or software (e.g., customized software code, customized software applications, customized user interfaces, etc.), or any combination thereof. In some examples, the wireless device of motor vehicle305may include at least one of interface310, or transceiver315, or at least one antenna320, or storage325, or communication manager330, or at least one processor335, or memory340, or at least one sensor345, or any combination thereof. Examples of the wireless device of motor vehicle305may include UE115ofFIG. 1orFIG. 2, or vehicle205or vehicle210ofFIG. 2.

In one example, motor vehicle305may receive an input from an occupant of motor vehicle305. In some cases, the input may include one or more descriptors of a motor vehicle other than motor vehicle305. As one example, the occupant of motor vehicle305may enter at least a portion of the input on a touchscreen display of interface310, or speak the input to a voice-control interface of interface310, or both. In some cases, the occupant of motor vehicle305may enter at least a portion of the input on a handheld mobile computing device (e.g., a smartphone, UE, etc.). Examples of the one or more descriptors include at least one of a make, or a model, or a vehicle type, or a year, or a color, or at least a portion of an identifier of a vehicle registration plate, or a descriptive name associated with the motor vehicle, or at least a portion of a vehicle identification number, or an owner code, or a vehicle class, or any combination thereof.

In some cases, motor vehicle305may identify a second motor vehicle (e.g., a motor vehicle other than motor vehicle305) based on the one or more descriptors from the input. In one example, the input entered by the occupant may include at least “a red truck with license plate XYZ did not stop at a crosswalk on 123 Main street.” Motor vehicle305may identify the second motor vehicle based at least in part on the specified red color of the vehicle, or the specified truck vehicle type, or the specified license plate XYZ, or the specified 123 Main street location, or any combination thereof.

In some cases, motor vehicle305may generate a feedback message for the second motor vehicle based at least in part on the input. In some cases, motor vehicle305may transmit the feedback message to the second motor vehicle based at least in part on motor vehicle305identifying the second motor vehicle. In some cases, the input from the occupant may include positive feedback, negative feedback, information indicating one or more actions performed by the second motor vehicle, a code mapped to a particular vehicle action, or any combination thereof.

In one example, motor vehicle305may generate a feedback message that includes a comment (e.g., “A user observed a red truck with license plate XYZ fail to stop at the crosswalk on 123 Main street. The observation was confirmed to match this vehicle.”). Additionally or alternatively, motor vehicle305may generate a feedback message that includes one or more symbols. For example, the feedback message may be configured by the occupant or by motor vehicle305to include a negative symbol (e.g., a thumbs down, a red X, a minus sign, etc.) based on motor vehicle305identifying negative-feedback information in the input entered by the occupant. In some cases, motor vehicle305may generate a feedback message that includes a positive symbol (e.g., a thumbs up, a green checkmark, a plus sign, etc.) based on motor vehicle305identifying positive-feedback information in the input entered by the occupant.

In some cases, motor vehicle305identifying the second motor vehicle may include motor vehicle305identifying one or more motor vehicles within a radius of motor vehicle305, where the one or more motor vehicles include the second motor vehicle. In some cases, motor vehicle305may display a map of the one or more motor vehicles via interface310based at least in part on trajectory information of the second motor vehicle. In some cases, the second motor vehicle may send its trajectory information to motor vehicle305. In some cases, motor vehicle305may determine the trajectory information of the second motor vehicle via sensor345. In some cases, the trajectory information may include a speed, or a heading, or a location, or any combination thereof. In one example, trajectory information of the second motor vehicle may be determined based at least in part on a GPS sensor of the second motor vehicle. Similarly, trajectory information of motor vehicle305may be determined based at least in part on a GPS sensor of motor vehicle305(e.g., sensor345).

In some cases, motor vehicle305may receive a selection of the second motor vehicle from an occupant of motor vehicle305. For example, motor vehicle305may receive the selection via interface310(e.g., an operating system, a display, a touchscreen interface, an onscreen keyboard, a physical keyboard, a pointer device, a voice-controlled interface) based at least in part on displaying the map of the one or more motor vehicles.

In some examples, the motor vehicle305may provide suggestions of feedback messages or target vehicles, or both (e.g., based on heuristics and analysis of sensor data harvested and obtained by the motor vehicle305). For example, identifying the second motor vehicle may include motor vehicle305identifying an outlier criteria associated with the second motor vehicle in relation to one or more motor vehicles within a radius of motor vehicle305. In some cases, based on the outlier criteria, motor vehicle305may output or display (e.g., via interface310) a suggested motor vehicle to receive the feedback message (e.g., the second motor vehicle). In some cases, the input from the occupant of motor vehicle305may confirm that the motor vehicle suggested by motor vehicle305is the intended recipient of the feedback message (e.g., second motor vehicle). In some cases, the outlier criteria may be based on at least one of a speed differential between the second motor vehicle and at least one of the one or more other vehicles, or a speed differential between the second motor vehicle and a speed limit, or a change in speed for the second motor vehicle, or braking activity of the second motor vehicle, or a lane change by the second motor vehicle, or a quantity of lane changes by the second motor vehicle, or any combination thereof.

In one example, the outlier criteria may include one or more thresholds, or tables, or algorithms, or any combination thereof that motor vehicle305uses to determine whether the operations of a vehicle are within a range that is predetermined to indicate safe driving (e.g., driving under a speed limit, braking at a rate predetermined to be moderate, accelerating at a rate predetermined to be moderate, yielding to pedestrians, obeying traffic lights and traffic signs, etc.) or indicate unsafe driving (e.g., driving above a speed limit, braking at a rate predetermined to be excessive, accelerating at a rate predetermined to be excessive, failing to yield to pedestrians, disobeying traffic lights and traffic signs, etc.). The outlier criteria may enable motor vehicle305to identify an outlier (e.g., a vehicle driving in a predetermined unsafe manner).

In one example, motor vehicle305may determine the current speed of the second motor vehicle (e.g., via sensor345) or the second motor vehicle may transmit to motor vehicle305the current speed of the second motor vehicle and motor vehicle305may determine that the second motor vehicle is traveling substantially faster than other nearby vehicles (e.g., vehicle within some radius of motor vehicle305or a communication range of transceiver315and antenna320). In another example, motor vehicle305may determine its current location (e.g., via sensor345) and determine the speed limit for the current location and determine a speed differential between the second motor vehicle and the determine speed limit. In some cases, motor vehicle305may determine a rate of deceleration of the second motor vehicle and compare the deceleration rate to a deceleration rate threshold to determine whether the braking of the second motor vehicle is excessive (e.g., the measured deceleration rate exceeds the deceleration rate threshold). In some examples, motor vehicle305may sense that the second motor vehicle is braking, but that one or more brake lights of the second motor vehicle are not functioning properly (e.g., not turning on, flickering, etc.). In some examples, motor vehicle305may sense (e.g., via an image sensor such as sensor345) that the second motor vehicle changes lanes without using a turning signal.

In some cases, based on the outlier criteria, motor vehicle305may output or display (e.g., via interface310) a suggested feedback message. In some cases, the input from an occupant of motor vehicle305may confirm the suggested feedback message as the feedback message. For example, interface310may display the generated feedback message and prompt the occupant to approve sending the feedback message. In some cases, interface310may allow the occupant to modify the suggested feedback message before transmitting the feedback message (e.g., via touchscreen, voice controls, etc.).

In some examples, motor vehicle305identifying the second motor vehicle may include motor vehicle305identifying a vehicle identifier based on the input received from the occupant of motor vehicle305. In some cases, motor vehicle305may identify a match between the vehicle identifier and a known attribute or determined attribute of the second motor vehicle (e.g., a vehicle color from the input matches the vehicle color of the second motor vehicle, a vehicle type from the input matches the vehicle type of the second motor vehicle, etc.). In some cases, motor vehicle305may obtain from the second motor vehicle or a server associated with motor vehicle305and the second motor vehicle one or more attributes or descriptors of the second motor vehicle. Additionally or alternatively, motor vehicle305may determine in real time (e.g., via sensor345) one or more attributes or descriptors of the second motor vehicle before motor vehicle305receives the input or after motor vehicle305receives the input. For example, sensor345may capture an image of the second motor vehicle and processor335may analyze the captured image to determine a color of the second motor vehicle.

In some cases, the vehicle identifier includes at least one of a make, or a model, or a vehicle type, or a year, or a color, or at least a portion of an identifier of a vehicle registration plate, or a descriptive name associated with the motor vehicle, or at least a portion of a vehicle identification number, or an owner code, or a vehicle class, or any combination thereof. Examples of the vehicle type include coupe, sedan, hatchback, wagon, crossover, sport utility vehicle, truck, van, minivan, sports car, bus, shuttle, semi-trailer truck, limousine, motorcycle, etc. In some cases, the vehicle identifier includes information from the input that is manually entered by the occupant of motor vehicle305.

In some examples, motor vehicle305may probe the second motor vehicle (e.g., wirelessly harvest information about the second motor vehicle). Probing may refer to an information querying or discovery technique supported by a vehicle-supported wireless communications protocol. In some cases, motor vehicle305may probe one or more motor vehicles detected by sensors included in motor vehicle305. For example, motor vehicle305may scan for motor vehicles unprompted by the user (e.g., periodically scan for motor vehicles based on some scanning schedule) or based on a prompt from the user (e.g., based on a command entered by the user to perform the scan). In some cases, motor vehicle305may detect a motor vehicle based on the scan and probe the motor vehicle. Probing the motor vehicle may yield information about the motor vehicle, such as at least one of a descriptive name associated with the motor vehicle, or at least a portion of a vehicle identification number (VIN), or an owner code, or a vehicle class.

In some cases, a probed motor vehicle may opt not to respond to the probe by motor vehicle305(e.g., to maintain anonymity), or the probed motor vehicle may respond with only limited information (e.g., only the vehicle class). If however, the probed motor vehicle does respond with information, motor vehicle305may use the obtained information when prompting the user with a suggestion of a target motor vehicle for feedback (e.g., motor vehicle305may supplement information used as a vehicle identifier with information obtained through the probing). Additionally or alternatively, motor vehicle305may be able to obtain additional information based on the information obtained through the probing (e.g., may be able to decode a VIN obtained through probing to obtain the make, model, or year of the probed motor vehicle).

In some examples, motor vehicle305identifying the second motor vehicle may include motor vehicle305identifying a photograph of the second motor vehicle (e.g., captured in real time by sensor345before motor vehicle305receives the input or after motor vehicle305receives the input), motor vehicle305comparing the photograph to a database of vehicle photographs, and motor vehicle305identifying a match based on the comparison (e.g., determine at least one of a vehicle type, or a vehicle make, or a vehicle model, or any combination thereof).

In some examples, motor vehicle305transmitting the feedback message to the second motor vehicle may include motor vehicle305transmitting the feedback message as part of a broadcast message that is configured to reach any motor vehicle within some radius of motor vehicle305(e.g., a communication range of transceiver315and antenna320). In some cases, motor vehicle305may transmit a warning about the second motor vehicle to one or more other motor vehicles within some vicinity of motor vehicle305.

In some examples, motor vehicle305may implement one or more techniques to limit abuse or excessive use of feedback mechanisms. For example, motor vehicle305may restrict a number of feedback messages a user (e.g., the occupant of motor vehicle305) is allowed to send based on a time period, or a token bucket mechanism, or a geographic area (e.g., whether a number of feedback message sent within the geographic area exceeds a threshold), or any combination thereof. In one example, after motor vehicle305transmits a feedback message from an occupant of motor vehicle305, motor vehicle305may allow the occupant to send another feedback message after some number of miles drive or some amount of driving time. In some cases, motor vehicle305may allow the occupant to send some number of feedback messages for a period of time (e.g., up to 10 messages per hours, etc.).

In some examples, motor vehicle305may provide protection against feedback message spamming or feedback message trolls. For example, motor vehicle305may access user profile information for the occupant, identify that a quantity of negative feedback messages sent by the occupant satisfies a threshold. For example, motor vehicle305may determine that an occupant has only sent negative feedback messages for at least some time period (e.g., the number of negative feedback messages exceeds a time threshold), or that the occupant has sent a number of negative feedback messages in a row (e.g., the number of negative feedback messages exceeds a quantity threshold) or that occupant has sent a number of negative feedback message to the second motor vehicle (e.g., the number of negative feedback messages exceeds a receiving-vehicle threshold). In some examples, when motor vehicle305detects a negative feedback message for the second motor vehicle, motor vehicle305may display (e.g., via interface310) a suggested positive feedback message for the second motor vehicle based on the quantity of negative feedback messages satisfying the threshold. In some cases, the feedback message may include the suggested positive feedback message (e.g., a thumbs up, a smiley face, a waving hand, etc.).

In some examples, motor vehicle305may transmit a message to a device (e.g., UE115, base station105) included in a wireless communications network based on the feedback message. In some cases, the feedback message may be sent using a vehicle-to-everything or vehicle-to-vehicle protocol.

In some examples, motor vehicle305may receive a feedback message, identify a vehicle identifier in the feedback message, and determine that the feedback message is intended for motor vehicle305based on identifying the vehicle identifier. In some cases, motor vehicle305may display on a display of the motor vehicle305(e.g., interface310) information based on the feedback message. In some examples, motor vehicle305may display a notification that the feedback message has been received. In some cases, motor vehicle305displaying information associated with the feedback message may include motor vehicle305displaying a notification of the feedback message, or information from the feedback message, or a warning based on the feedback message, or information indicating one or more actions performed by motor vehicle305, or a code mapped to a particular vehicle action, or any combination thereof. In some examples, motor vehicle305may receive the feedback message as part of a broadcast message configured to reach any motor vehicle within a radius of a user associated with the feedback message

In some cases, motor vehicle305may maintain an anonymity of a sender of a feedback message or a receiver of a feedback message (e.g., to avoid any potential incidents of road-rage or retribution, etc.). In some examples, motor vehicle305may delay display of the information until the motor vehicle comes to a stop, or until the motor vehicle is shifted into park, or until a source of the feedback message is separated from the motor vehicle by a first threshold distance, or until a quantity of motor vehicles within a second threshold distance satisfies a threshold quantity. As one example, motor vehicle305and the second motor vehicle may be driving in a remote or rural road, or during off-peak hours, where revealing the identity of motor vehicle305may be unavoidable (e.g., the second motor vehicle receives negative feedback and motor vehicle305is the only other vehicle on the road). Accordingly, the second motor vehicle may determine that motor vehicle305is the only other vehicle on the road and based on this determination the second motor vehicle may delay notifying an occupant of the second motor vehicle of the negative feedback.

In some examples, motor vehicle305may determine an aggregate driving score for motor vehicle305based on the feedback message and one or more prior feedback messages received by motor vehicle305, and display (e.g., via interface310) the aggregate driving score on the display of the motor vehicle. In some cases, motor vehicle305may indicate that the feedback message is positive or negative. In some cases, motor vehicle305may store the feedback message in storage325and accumulate multiple received feedback messages over some time period. In some cases, motor vehicle305may calculate a cumulative feedback score based on motor vehicle305analyzing the accumulated multiple received feedback messages. In some examples, motor vehicle305may display the cumulative feedback score (e.g., via interface310). In some cases, motor vehicle305may transmit (e.g., via transceiver315) one or more feedback message to cloud storage and/or to other vehicles within some radius of motor vehicle305.

In some cases, motor vehicle305may execute a command (e.g., alter a behavior of or prompt an action by motor vehicle305) based on the feedback message or the accumulated multiple received feedback messages. Examples of the executed command may include limiting a speed of motor vehicle305, altering a speed of motor vehicle305, autonomously pulling motor vehicle305off the road, disabling motor vehicle305. In some cases, motor vehicle305may transmit a notification based on the feedback message or the accumulated multiple received feedback messages. For example, motor vehicle305may transmit a notification to a person that is financially responsible for motor vehicle305, to parents of a driver of motor vehicle305, to a corporation that owns motor vehicle305, etc.

In some cases, motor vehicle305determining that motor vehicle305is an intended recipient of the feedback message may include motor vehicle305identifying an attribute or descriptor of motor vehicle305that is stored in storage325and/or storage in a cloud storage, comparing the vehicle identifier to the attribute of motor vehicle305, and identifying a match between the vehicle identifier and the attribute of motor vehicle305.

In some cases, motor vehicle305may receive a second feedback message, determine that the second feedback message is intended for motor vehicle305based on information in the second feedback message, and identify a correlation between a previous feedback message and the second feedback message. In some cases, motor vehicle305may correlate reception of multiple feedback messages from two or more users (e.g., at least one pedestrian and at least one occupant of a motor vehicle, or at least one occupant of a motor vehicle and at least one occupant of a second motor vehicle, etc.) before processing or displaying the correlated feedback message. In some examples, feedback message may be correlated based on time and location of the users sending the feedback messages (e.g., to filter out any spurious negative feedback reports). As one example, an aggressive driver weaving in and out of traffic down a freeway would likely receive multiple negative reports in a short amount of time from multiple users, resulting in corroborations of the observed behavior. Accordingly, correlating multiple similar reports as relating to the same incident or behavior provides corroboration that feedback messages are valid, reducing the potential for abuse. For example, motor vehicle305may display or take any other responsive action described herein based on a number of correlated and consistent feedback messages satisfying or a threshold, or may discard or otherwise refrain from taking any other responsive action described herein based on a number of correlated and consistent feedback messages failing to satisfy the threshold or based on a number of correlated and inconsistent feedback messages satisfying a second threshold.

In some cases, motor vehicle305displaying the information is based on the correlation between the previous feedback message and the second feedback message. In some examples, motor vehicle305may identify a correlation between a previous feedback message and the second feedback message and allow information from the previous feedback message or the second feedback message, or both, to be received or stored or displayed on motor vehicle305based on the correlation between the previous feedback message and the second feedback message.

In some examples, motor vehicle305may receive a third feedback message, determine that the third feedback message is not intended for the motor vehicle, and discard the third feedback message based on motor vehicle305determining that the third feedback message is not intended for motor vehicle305. In some examples, motor vehicle305may receive a fourth feedback message, identify user profile information for a source of the fourth feedback message, and discard the fourth feedback message or adjust display of information from the fourth message based at least in part on the user profile information.

At405, motor vehicle205-amay identify a driving behavior. In one example, an occupant of vehicle205-amay enter information in a device (e.g., a smartphone, a computer integrated in vehicle205-a, etc.) and vehicle205-amay identify a driving behavior based on the entered information.

At410, motor vehicle205-amay identify motor vehicle210-abased on the entered information. At415, motor vehicle205-amay generate a feedback message based on identifying vehicle210-a.

The input may include information (e.g., a vehicle identifier) that identifies vehicle210-a. Examples of the vehicle identifier may include at least one of a make, or model, or vehicle type, or year, or color, or at least a portion of an identifier of a vehicle registration plate, or a descriptive name associated with the motor vehicle, or at least a portion of a vehicle identification number, or an owner code, or a vehicle class, or location of motor vehicle210-a, or location of motor vehicle205-a, or any combination thereof. In some cases, the input may include a driving behavior associated with motor vehicle210-a.

At420, motor vehicle205-amay broadcast the feedback message to motor vehicles within a communication range of motor vehicle205-a. At420, motor vehicle210-aand motor vehicle210-bmay be within the communication range of motor vehicle205-a. Accordingly, at420motor vehicle210-aand motor vehicle210-bmay receive the broadcast feedback message.

At425, motor vehicle210-amay determine that motor vehicle210-ais an intended recipient of the feedback message. For example, motor vehicle210-amay analyze the feedback message and determine that information in the feedback message identifies motor vehicle210-a.

At430, motor vehicle210-amay optionally delay displaying information from or information based on the feedback message. For example, motor vehicle210-amay delay displaying any related information based on a detected privacy or anonymity concern (e.g., motor vehicle210-adetermines that motor vehicle205-aand motor vehicle210-aare the only two motor vehicles within some radius of motor vehicle210-a).

At435, motor vehicle210-amay display information from or information based on the feedback message. For example, motor vehicle210-amay display a notification that the feedback message has been received.

At440, motor vehicle210-bmay determine that motor vehicle210-bis not an intended recipient of the feedback message. For example, motor vehicle210-bmay analyze the feedback message and determine that information in the feedback message does not match any attribute or descriptor associated with motor vehicle210-b.

At445, motor vehicle210-bmay discard the feedback message based on motor vehicle210-bdetermining that motor vehicle210-bis not an intended recipient of the feedback message.

In some cases, the probing manager730may probe one or more motor vehicles detectable by a device associated with communications manager705(e.g., a motor vehicle, a mobile computing device, etc.). For example, probing manager730may scan for a motor vehicle unprompted (e.g., periodically scan for motor vehicles based on some scanning schedule) or based on a prompt from a user (e.g., based on a command entered by the user to perform the scan). In some cases, probing manager730may detect a motor vehicle based on the scan and probe the motor vehicle. Probing the motor vehicle may yield information about the motor vehicle.

In some examples, the feedback reception manager735may receive a second feedback message. In some examples, the analysis manager740may determine (e.g., at a vehicle) that the second feedback message is intended for the motor vehicle based on information in the second feedback message. In some examples, the analysis manager740may identify a correlation between the feedback message and the second feedback message, where displaying the information is based on the correlation between the feedback message and the second feedback message.

In some examples, the feedback reception manager735may receive a third feedback message. In some examples, the analysis manager740may determine (e.g., at a vehicle) that the third feedback message is not intended for the motor vehicle. The analysis manager740may discard the third feedback message based on determining that the third feedback message is not intended for the motor vehicle.

In some examples, the feedback reception manager735may receive a fourth feedback message.
