Step 73: and receiving feedback information sent by at least one second vehicle, and adjusting the running state of the vehicle.

Steps 71 to 73 have the same or similar technical schemes as any embodiment of the present application, and are not described here.

Step 74: in the course of adjusting the running state of the vehicle, a vehicle collision detection is performed.

Step 75: and determining whether to continuously adjust the running state of the vehicle according to the vehicle collision detection result.

And continuing to adjust the vehicle running state in response to the vehicle collision detection result being lower than the preset value. If the vehicle collision detection result is lower than the preset value, which indicates that no collision occurs at this time, the first vehicle can continuously adjust the running state of the vehicle.

And responding to the fact that the vehicle collision detection result is higher than or equal to a preset value, carrying out collision reminding or automatically stopping adjusting the running state of the vehicle. If the vehicle collision detection result is higher than or equal to the preset value, the collision is easy to occur at the moment, and the collision reminding is carried out so that the first vehicle driver stops adjusting the vehicle running state.

If the vehicle collision detection result is higher than or equal to the preset value, the first vehicle automatically stops adjusting the vehicle running state, wherein the situation that the collision is easy to happen at the moment is indicated.

If the vehicle collision detection result is higher than or equal to a preset value, the collision is easy to occur at the moment, collision reminding is carried out, and if the first vehicle driver does not make a stopping operation, the first vehicle automatically stops adjusting the vehicle running state.

In an application scenario, in response to the radar sensor detecting the presence of a third vehicle within a preset range, the third vehicle is located between the first vehicle and the target second vehicle, the first vehicle establishes a communication connection with the third vehicle using the communication device, and disconnects the connection with the target second vehicle. The description is given with reference to fig. 2 and 8:

in fig. 2, vehicle a is the first vehicle, and vehicles B, C, D, and E may be the second vehicle. At this time, it appears that the vehicle F is within the preset range of the vehicle a as shown in fig. 8, and the vehicle F is located between the vehicle a and the vehicle D. When the vehicle F has direct contact with the vehicle A, the vehicle A establishes a communication connection with the vehicle F by using the communication device and disconnects the vehicle D. I.e. vehicles within the preset range of vehicle a at this time are vehicle B, vehicle C, vehicle F and vehicle E.

When the vehicles in the range change, the connection relation of the directly-related vehicles is switched in time, so that the communication with the directly-related vehicles is facilitated, the timely communication between the vehicles is improved, and the problem that the vehicles cannot communicate timely due to the change is solved.

In an application scenario, a first vehicle sends yielding information to a target second vehicle to yield the target second vehicle. Referring to fig. 2, in fig. 2, a vehicle a is the first vehicle, and a vehicle B, a vehicle C, a vehicle D, and a vehicle E may be the second vehicle. Vehicle a sends yielding information to vehicle E to yield vehicle E. The vehicle a can travel quickly. For example, when the vehicle a is a special vehicle, the yielding information may be sent to the target second vehicle to yield the target second vehicle. For example, the vehicle A can be any special vehicle such as a fire truck, a police car, an ambulance and the like.

By giving out the yielding way to the front vehicle, the yielding way of the front vehicle is realized, the operations of lane changing, overtaking and the like of the vehicle can be reduced, the running efficiency of the vehicle is improved, and the processing efficiency is improved under special conditions such as patient rescue and fire disaster scene.

In an application scenario, a first vehicle sends forward road information to at least one second vehicle located behind the first vehicle to cause the at least one second vehicle behind to adjust a vehicle driving state. Referring to fig. 2, in fig. 2, a vehicle a is the first vehicle, and a vehicle B, a vehicle C, a vehicle D, and a vehicle E may be the second vehicle. The vehicle a transmits forward road information to the vehicle D so that the vehicle D adjusts the vehicle running state. If the vehicle A sends the front road jam information to the vehicle D, the vehicle D adjusts and reduces the running speed of the vehicle.

The communication capability is used for transmitting road condition information to avoid rear-end collision or other secondary accidents of the rear vehicles.

In a certain scene, the vehicles need to communicate with other road participants in the driving process, more information cannot be transmitted in the current unidirectional limited communication mode, and meanwhile, information transmission under special conditions cannot be met. For devices such as wireless communication devices and radar sensors arranged in the vehicle, other vehicles in the front-back left-right direction can be identified in the running process of the vehicle, when the detection range can be limited within 150m, the vehicle exceeding the detection range can be automatically disconnected, and the vehicle exceeding the detection range can not directly influence the running structure of the vehicle.

The vehicle in the front, back, left and right directions can be judged based on the radar and the sensor in the running process of the vehicle, if the vehicle needs to overtake and change the lane, the lane change notification can be sent to the vehicle in the adjacent lane through the communication equipment, the default non-starting condition can be triggered through the turn signal lamp, the vehicle can send information to the vehicle in the lane in the steering direction after turning the turn signal lamp, the information can also be triggered through the voice in the vehicle, the other vehicle can receive the information, the vehicle can be recovered, if the lane change of the vehicle is not allowed, the information can be directly returned, and the situation that the lane change vehicle cannot know the state of the vehicle behind is avoided.

In the same way, the emergency matters occur as front traffic accidents, and the vehicles in case of accidents can transmit information to the rear vehicles through the communication equipment, so that secondary accidents are avoided.

Specifically, the vehicle uses the own vehicle-mounted sensor and the radar to scan the nearby vehicle, and when other vehicles enter the 150m range and no shielding object exists in the middle of the front, rear, left and right directions of the vehicle, the vehicle belongs to the vehicle which directly affects the composition of the vehicle.

Specifically, for a vehicle that constitutes a direct influence of the running of the own vehicle, the own vehicle uses the vehicle-mounted communication device to communicate with the own vehicle in a link, and if the vehicle exceeds the range or other vehicles or obstacles are inserted in the middle during the running, the own vehicle is disconnected from the own vehicle, and a vehicle that newly enters the direct influence range is connected as a new direct influence vehicle.

Specifically, after the connection between the vehicle and the directly affected vehicle is completed, other behaviors such as steering, overtaking, braking, lane changing and the like of the vehicle occur, and related information is sent to cooperatively communicate with the vehicle at the rear, when the running of the vehicle is inconsistent with the communication result, such as the vehicle at the rear is suddenly accelerated in the lane changing process, the system detects the risk of collision, such as the possibility of collision of the vehicle caused by the crossing of the running direction, the driver is warned of danger, if the situation that the collision driver is not interfered is judged to exist finally, the vehicle can automatically intervene, and the lane changing is stopped to avoid accidents.

The vehicle can use the scheme to carry out cooperative communication in the running process, so that accidents caused by misunderstanding or unknown information are reduced, or the communication capacity is used for carrying out the transmission of road condition information to avoid rear-end collision or other secondary accidents of the rear vehicle, and meanwhile, the ambulance and the fire truck can give off the running road for the front vehicle, so that the influence on patient rescue and fire disaster treatment is avoided.
