Autonomous vehicles as referred to herein include fully autonomous vehicles, as well as vehicles having an autonomous mode. The autonomous vehicle to which the present disclosure is applicable has the following basic features: for example, such vehicles are mounted with a plurality of sensors or positioning devices, such as image pickup devices, laser radars, millimeter wave radars, ultrasonic sensors, vehicle-to-anything communication (V2X) devices, highly automated driving (HAD, highly Automated Driving) maps, etc., which are capable of detecting the environment around the vehicle, such as surrounding objects, obstacles, infrastructure, etc.; these vehicles are capable of detecting the position of the current vehicle by one of a Global Navigation Satellite System (GNSS) and a sensor detection result and a HAD map or a combination thereof; the vehicles can acquire navigation paths through an online server; these vehicles are able to plan a route to be travelled based on the perception and location results; such vehicles can also send control signals to the power system, steering system, braking system, etc., based on the planned route.
Fig. 1 shows a schematic view of a system 100 for post-highway traffic accident handling according to an embodiment of the present disclosure. As shown in fig. 1, the system 100 for post-processing of highway traffic accident includes an information acquisition unit 110, a calculation unit 120, an information distribution unit 130, and an execution unit 140.
In fig. 1, the information collection unit 110 is configured to collect information of a traffic accident scene in response to confirming that a current vehicle encounters the traffic accident. The traffic accident may be a unilateral or multiparty traffic accident between the current vehicle and other vehicles or roadside facilities, or may be a situation that the current vehicle fails and cannot run, or a situation that an obstacle in front hinders the current vehicle from passing. In one example, the determination of the encounter with a traffic accident is made manually by an onboard person. The occupants of the vehicle include the driver and/or occupants, and for an unmanned vehicle, there is no driver, but there may be occupants in the vehicle. The person on the vehicle is not limited to being located on the vehicle, but is still referred to as the person on the vehicle after the person on the vehicle gets off the vehicle. In the case where the system 100 is located on a mobile device of an onboard person, by means of the application installed on the mobile, it can be determined that a traffic accident is encountered by clicking a button of the application. For example, the onboard personnel manually select to launch an application on the touch screen of the display device.
In another example, the determination of the occurrence of a traffic accident is made by the information collection unit 110. The information acquisition unit 110 may comprise a speed measuring device and/or a sensor for detecting the speed or acceleration of the current vehicle and/or for detecting the distance of the current vehicle from surrounding objects; the information collection unit 110 may also obtain information detected by a speed measuring device and/or a sensor installed on the current vehicle through wireless communication. The speed measuring device can be used for detecting the speed or acceleration of the current vehicle, and the sensor can be used for detecting the distance between other objects and the current vehicle. For example, the speed measuring device may be a mobile device of the person on the vehicle or a speed measuring device mounted on the current vehicle, such as a smart phone or an acceleration sensor mounted on the current vehicle. The current vehicle speed on the high-speed traffic lane is reduced to 0km/h from the normal running speed, for example, 120km/h in a short time, and the current vehicle can be judged to encounter a traffic accident and is in danger of being collided with by the rear-running vehicle. The acceleration of the current vehicle or the object in the vehicle can be detected through the acceleration sensor, so that the vehicle is judged to encounter a traffic accident according to the acceleration. For example, it may be determined that the current vehicle has an external collision, if the linear acceleration of the current vehicle or the object in the vehicle suddenly goes backward or forward is greater than a threshold value, or if the angular acceleration of the rollover or yaw is greater than a threshold value. In one example, a sensor (e.g., an imaging device, a laser radar, a millimeter wave radar, and an ultrasonic sensor) installed outside the current vehicle detects that the current vehicle is less than a threshold value, e.g., 5cm, from other objects around, and it may be determined that the vehicle has suffered a traffic accident. If the information collection unit 110 is located on a mobile device, it may determine that a traffic accident has been encountered by communicating wirelessly with the current vehicle. The wireless communication is for example via a mobile network, wi-Fi or bluetooth.
In one example, the information of the traffic accident scene includes information of the current vehicle and information of the person on the vehicle. The information of the vehicle may include any one or a combination of any of the following: the type of traffic accident, the damage condition of the current vehicle and the position of the current vehicle. The current vehicle location may include a lane in which the current vehicle is located. The information of the personnel on the vehicle may include any one or a combination of any of the following: the actions, positions and movement directions of the personnel on the vehicle. The location of the person on the vehicle may be used to determine whether it enters a safety zone; the actions of the personnel on the vehicle can be used to determine whether photographing of the accident scene is completed. The information acquisition unit 110 includes a combination of any one or more selected from the following sensors installed in the current vehicle: imaging devices, lidar, millimeter wave radar and ultrasonic sensors.
In fig. 1, the computing unit 120 is configured for planning an evacuation route of personnel on the vehicle, guidance for taking a picture of the traffic accident scene and a target parking position of the current vehicle based at least on the information of the traffic accident scene. The information of the traffic accident scene is, for example, the type of traffic accident and the condition of the current vehicle. The types of traffic accidents may be single accidents, double or multiple accidents, vehicle faults and obstacles in front. Planning the evacuation route of the person on the vehicle may include determining the evacuation route of the person on the vehicle based on the information and/or map data of the traffic accident scene. Planning the target parking position of the current vehicle may include determining the target parking position of the current vehicle based on information and/or map data of the traffic accident scene. In one example, the target parking location of the current vehicle is on an emergency lane. Preferably, a trajectory from the position of the current vehicle to the target parking position of the current vehicle may be planned according to the target parking position of the current vehicle.
In this example, determining how to photograph the traffic accident scene is based on the type of traffic accident and the current situation of the vehicle to meet the requirements of the insurance company or the traffic management department. Moreover, the requirements for taking photographs may be different in different areas or for different insurers. Therefore, the guidance for photographing the traffic accident scene may be performed according to a rule stored in advance, and photographing at a plurality of angles, for example, photographing from 3 angles, is sometimes required. The requirements for photographing the vehicle may be different for single-party accidents, double-party or multi-party accidents, vehicle faults and situations with obstacles in front, and may not even be required for photographing the vehicle, such as for example, vehicle faults and situations with obstacles in front. And the personnel on the vehicle photographs the traffic accident scene according to the guidance of photographing the traffic accident scene. The direction for photographing the traffic accident scene comprises the photographing position and/or angle.
In fig. 1, the information issuing unit 130 is configured to issue an evacuation route of the person on the vehicle to the person on the vehicle and a guide to photograph the traffic accident scene. The information distribution unit 130 may include a display device that distributes visual information to the person on board and/or a speaker device that distributes audible information, for example, via a display device and/or a speaker of the person on board's mobile device. In the case where the information distribution unit 130 includes a display device, the in-vehicle person can confirm that the current vehicle encounters a traffic accident through the display device in the information collection unit 110. The released evacuation route may be a target place of releasing the evacuation, such as a safety zone. The safety zone is, for example, outside of the isolation zone. Thus, the release evacuation route may include text, such as "please stand outside the isolation zone". Preferably, after the evacuation route is issued to the onboard person and the onboard person is evacuated to the safety zone, guidance for photographing the traffic accident scene is issued to the onboard person. The evacuation of the occupants to the safety zone may be detected by the information collection unit 110 or may be manually confirmed by the occupants, such as by a display device. As described above, the instruction to take a photograph of the traffic accident scene is issued to the person on the vehicle including the case where the photographing is required and the case where the photographing is not required. For situations where photographing is not required, the current vehicle is provided with driving assistance to the current vehicle target parking position directly by the execution unit 140. The personnel on the vehicle can take a picture according to the guidance of taking a picture of the traffic accident scene, and the end of the picture can be detected by the information acquisition unit 110, or can be manually confirmed by the personnel on the vehicle, for example, by a display device.
In fig. 1, the execution unit 140 is configured to provide the current vehicle with assisted driving to the current vehicle target parking position in response to detecting that the person on the vehicle has completed photographing the traffic accident scene. The personnel on the vehicle having completed photographing the traffic accident scene includes a situation in which photographing the traffic accident scene is not required. In one example, the assisting driving includes automatically controlling a steering system, an acceleration system, and a deceleration system to cause the current vehicle to travel to a target parking location of the current vehicle along a trajectory to the target parking location. In one example, the current vehicle is automatically parked alongside by remote control. For example, after photographing the traffic accident scene is completed, the personnel on the vehicle confirms and presses a button on the mobile phone to activate remote control automatic side parking, and automatically control steering and accelerating to run along the determined track. During automatic side parking, surrounding objects, such as vehicles coming from the rear, can be detected by the information acquisition unit 110. The braking is automatically controlled if a vehicle is detected that has arrived at the rear in a certain time (e.g. 5 s) on the lane before entering the other lane. Preferably, the turn signal is turned on during automatic driving; and (5) starting a hazard alarm flash lamp after stopping by the side.
Referring to fig. 2, an application example of a system for post-processing of highway traffic accidents according to an embodiment of the present disclosure is shown. In fig. 2, the system for post-processing of a highway traffic accident is installed on a mobile device in the form of an application program or application software (APP) or the like, for example, on a smartphone 2 of a person 3 shown on the vehicle. In the case where the system 100 is located on a mobile device of the person 3 on the vehicle, by means of an application installed on the mobile device, it is possible to determine that a traffic accident is encountered by clicking a button of the application; it is also possible to detect a traffic accident by a sensor (e.g., an image pickup device, a laser radar, a millimeter wave radar, an ultrasonic sensor, or an acceleration sensor) mounted on the current vehicle 1, and transmit information of the detected surrounding objects to the information acquisition unit 110 to determine whether the current vehicle 1 has suffered a traffic accident. After it is determined that a traffic accident is encountered, information of the traffic accident scene may be detected by a sensor (e.g., an image pickup device, a laser radar, a millimeter wave radar, or an ultrasonic sensor) mounted on the current vehicle 1, and the detected information of the traffic accident scene may be transferred to the information collection unit 110. The computing unit 120 is located in the smart phone 2, and is configured to plan an evacuation route of a person on the vehicle, a guidance for photographing a traffic accident scene, and a target parking position of the current vehicle 1 based on the type of traffic accident and the condition of the current vehicle 1. The information release unit 130 is configured to release the evacuation route of the person on the vehicle to the person on the vehicle 3, and after the person on the vehicle 3 is evacuated to the safety zone according to the evacuation route, the traffic accident scene is photographed according to the direction of photographing the traffic accident scene. After the photographing is completed, the execution unit 140 provides the current vehicle 1 with the assisted driving to the target parking position. The mobile device 2 is connected to the current vehicle 1 by wireless communication, such as mobile network, wi-Fi or bluetooth.
A method of post-processing of an expressway traffic accident according to an embodiment of the present disclosure will be described below with reference to the accompanying drawings. Fig. 3 is a flowchart illustrating a method S100 of post-highway traffic accident processing according to an embodiment of the present disclosure. The method S100 of post-highway traffic accident treatment is performed by the system 100 of post-highway traffic accident treatment described above.
As shown in fig. 3, in step S110, information of a traffic accident scene is collected in response to confirming that a current vehicle encounters the traffic accident. The traffic accident may be a unilateral or multiparty traffic accident between the current vehicle and other vehicles or roadside facilities, or may be a situation that the current vehicle fails and cannot run, or a situation that an obstacle in front hinders the current vehicle from passing. In one example, the determination of the encounter with a traffic accident is made manually by an onboard person. The occupants of the vehicle include the driver and/or occupants, and for an unmanned vehicle, there is no driver, but there may be occupants in the vehicle. The person on the vehicle is not limited to being located on the vehicle, but is still referred to as the person on the vehicle after the person on the vehicle gets off the vehicle. By means of the application installed on the mobile, it is possible to determine that a traffic accident is encountered by clicking a button of the application. For example, the onboard personnel manually select to launch an application on the touch screen of the display device.
In another example, the determination of a traffic accident is judged by the state of the current vehicle. The state of the current vehicle includes a speed or acceleration of the current vehicle and/or a distance of the current vehicle from surrounding objects. The speed or acceleration of the current vehicle is detected by a speed measuring device, and the distance between the current vehicle and surrounding objects is detected by a sensor; information detected by the speed measuring device and/or the sensor mounted on the current vehicle can also be obtained through wireless communication. For example, the speed measuring device may be a mobile device of the person on the vehicle or a speed measuring device mounted on the current vehicle, such as a smart phone or an acceleration sensor mounted on the current vehicle. The current vehicle speed on the high-speed traffic lane is reduced to 0km/h from the normal running speed, for example, 120km/h in a short time, and the current vehicle can be judged to encounter a traffic accident and is in danger of being collided with by the rear-running vehicle. The acceleration of the current vehicle or the object in the vehicle can be detected through the acceleration sensor, so that the vehicle is judged to encounter a traffic accident according to the acceleration. For example, the current vehicle or in-vehicle object is present. The sudden backward or forward linear acceleration is greater than a threshold value, or the rollover or yaw angular acceleration is greater than a threshold value, it may be determined that the current vehicle has an external collision. In one example, a sensor (e.g., an imaging device, a laser radar, a millimeter wave radar, or an ultrasonic sensor) mounted on a current vehicle detects that the current vehicle is less than a threshold value, e.g., 5cm, from other objects surrounding the current vehicle, and may determine that the vehicle has suffered a traffic accident. The mobile device may determine that a traffic accident is encountered by communicating wirelessly with the current vehicle. The wireless communication is for example via a mobile network, wi-Fi or bluetooth.
In one example, the information of the traffic accident scene includes information of the current vehicle and information of the person on the vehicle. The information of the vehicle may include any one or a combination of any of the following: the type of traffic accident, the damage condition of the current vehicle and the position of the current vehicle. The current vehicle location may include a lane in which the current vehicle is located. The information of the personnel on the vehicle may include any one or a combination of any of the following: the actions, positions and movement directions of the personnel on the vehicle. The location of the person on the vehicle may be used to determine whether it enters a safety zone; the actions of the personnel on the vehicle can be used to determine whether photographing of the accident scene is completed. The information of the traffic accident scene can be detected by any one or a combination of any plurality of the following sensors installed on the current vehicle: imaging devices, lidar, millimeter wave radar and ultrasonic sensors.
In step S120, an evacuation route of personnel on the vehicle, guidance for photographing the traffic accident scene, and a target parking position of the current vehicle are planned based at least on the traffic accident scene information. The information of the traffic accident scene is, for example, the type of traffic accident and the condition of the current vehicle. The types of traffic accidents may be single accidents, double or multiple accidents, vehicle faults and obstacles in front. Planning the evacuation route of the person on the vehicle may include determining the evacuation route of the person on the vehicle based on the information and/or map data of the traffic accident scene. Planning the target parking position of the current vehicle may include determining the target parking position of the current vehicle based on information and/or map data of the traffic accident scene. In one example, the target parking location of the current vehicle is on an emergency lane. Preferably, a trajectory from the position of the current vehicle to the target parking position of the current vehicle may be planned according to the target parking position of the current vehicle.
In this example, determining how to photograph the traffic accident scene is based on the type of traffic accident and the current situation of the vehicle to meet the requirements of the insurance company or the traffic management department. Moreover, the requirements for taking photographs may be different in different areas or for different insurers. Therefore, the guidance for photographing the traffic accident scene may be performed according to a rule stored in advance, and photographing at a plurality of angles, for example, photographing from 3 angles, is sometimes required. The requirements for photographing the vehicle may be different for single-party accidents, double-party or multi-party accidents, vehicle faults and situations with obstacles in front, and may not even be required for photographing the vehicle, such as for example, vehicle faults and situations with obstacles in front. And the personnel on the vehicle photographs the traffic accident scene according to the guidance of photographing the traffic accident scene. The direction for photographing the traffic accident scene comprises the photographing position and/or angle.
In step S130, an evacuation route of the person on board is issued to the person on board, and in response to detecting that the person on board has evacuated according to the evacuation route, guidance for photographing the traffic accident scene is issued to the person on board. Visual information may be distributed to the on-board personnel via a display device and/or audible information may be distributed to the on-board personnel via a speaker device. The released evacuation route may be a target place of releasing the evacuation, such as a safety zone. The safety zone is, for example, an isolation zone. Thus, the release evacuation route may include text, such as "please stand outside the isolation zone". Preferably, after the evacuation route is issued to the onboard person and the onboard person is evacuated to the safety zone, guidance for photographing the traffic accident scene is issued to the onboard person. The evacuation of the personnel on the vehicle to the safety zone can be confirmed by detecting the position of the personnel on the vehicle by a sensor, or can be confirmed manually by the personnel on the vehicle, for example by a display device. As described above, the instruction to take a photograph of the traffic accident scene is issued to the person on the vehicle including the case where the photographing is required and the case where the photographing is not required. In the case where photographing is not required, S140 is directly performed to provide the current vehicle with the auxiliary driving to the current vehicle target parking position. The personnel on the vehicle can take photos according to the guidance of taking photos of the traffic accident scene, and the shooting end can be confirmed by detecting the actions of the personnel on the vehicle through a sensor, or can be manually confirmed by the personnel on the vehicle, for example, through a display device.
In step S140, in response to detecting that the person on the vehicle has completed photographing the traffic accident scene, the current vehicle is provided with assisted driving to the current vehicle target parking position. The personnel on the vehicle having completed photographing the traffic accident scene includes a situation in which photographing the traffic accident scene is not required. In one example, the assisting driving includes automatically controlling a steering system, an acceleration system, and a deceleration system to cause the current vehicle to travel to a target parking location of the current vehicle along a trajectory to the target parking location. In one example, the current vehicle is automatically parked alongside by remote control. For example, after photographing the traffic accident scene is completed, the personnel on the vehicle confirms and presses a button on the mobile phone to activate remote control automatic side parking, and automatically control steering and accelerating to run along the determined track. During automatic side parking, surrounding objects, such as vehicles coming from behind, can be detected by sensors mounted on the current vehicle. The braking is automatically controlled if a vehicle traveling backward in a certain time (e.g., 5 s) is detected on the lane before entering the other lane. Preferably, the turn signal is turned on during automatic driving; and (5) starting a hazard alarm flash lamp after stopping by the side.
The method of the present disclosure may be completed by using a computer program, by collecting information of the traffic accident scene in step S110, the information of the traffic accident scene may be obtained by obtaining a sensor installed outside the current vehicle through wireless communication; in step S120, an evacuation route of personnel on the vehicle, guidance for photographing a traffic accident scene, and a target parking position of the current vehicle are planned; in step S130, firstly, issuing an evacuation route of the personnel on the vehicle to the personnel on the vehicle, and then issuing a guidance for photographing the traffic accident scene to the personnel on the vehicle; in step S140, assisted driving to the target parking position is provided to the current vehicle.
