Vehicle fleet collision avoidance system and method based on fish streaming

Abstract

The invention discloses a vehicle fleet collision avoidance system and method based on fish streaming and belongs to the field of vehicle active safety. The system comprises an information acquisition module, a communication module, an information interaction module and a man-machine interaction module. The information acquisition module comprises a vehicle-mounted CAN bus, a millimeter wave radar distance measurement sensor and a longitudinal acceleration sensor which is used for acquiring the speed, the acceleration and the vehicle distance of a corresponding vehicle; the communication module comprises a vehicle-mounted unit OBU which is used for transferring motion state data among vehicles; the man-machine interaction module comprises a display unit and a voice prompt unit which is used for displaying dangerous information to a driver; the information processing module calculates acceleration information of vehicle collision avoidance according to the information transferred by the information acquisition module and the communication module through a kinematic model based on fish streaming, the information is provided to the driver through the man-machine interaction module, and collaborative collision avoidance of a vehicle fleet is achieved. By means of the vehicle fleet collision avoidance system and method, the active safety of vehicle fleet driving can be effectively improved.

Description

technical field [0001] The invention belongs to the field of automobile active safety, and in particular relates to a team cooperative collision avoidance system and method based on fish school escape behavior. Background technique [0002] With the development of my country's economy, the number of cars has increased rapidly, and the number of traffic accidents has remained high. In the traditional environment, the collision avoidance strategies of all vehicles in the fleet are mainly formulated based on the feedback of their own sensors in a short time, especially when the car is driving at high speed, when a vehicle in the fleet brakes suddenly or there are other vehicles When being merged into the convoy, it is easy to cause a series of rear-end collisions, which poses a great threat to people's personal safety and property loss. Based on the above-mentioned content, the main defects in this field are summarized as follows: [0003] (1) The active safety of vehicles bas...

AI Technical Summary

Problems solved by technology

[0003] (1) The active safety of vehicles based on sensors cannot fully meet people's requirements for automobile safety. not playing well

[0004] (2) In the traditional environment, when a vehicle brakes suddenly, the reaction time of the driver of the vehicle behind it has a "chain reaction", and the driver of the vehicle behind it cannot identify the dangerous vehicle at the same time

[0005] (3) Generally speaking, building a control model for cooperative collision avoidance of fleets is extremely complex and has poor reliability;
