A multi-vehicle cooperative collision avoidance system and method based on vehicle-vehicle communication

Abstract

The invention discloses a multi-vehicle coordination collision avoidance system and method based on vehicle-vehicle communication, and belongs to the field of vehicle active safety. The system comprises an information collection module, a communication module, an information processing module, and a voice prompt module. The method provided by the invention comprises the steps: collecting the movement data of a target vehicle and a front vehicle in real time through the information collection module, comparing the safety distance of the target vehicle with the distance from the target vehicle to the front vehicle, and judging the danger state of the two vehicles; and starting to judge whether the target vehicle and the front vehicle meet a coordination collision avoidance condition of two vehicles or not when a danger signal is received. When the target vehicle and the front vehicle meet the coordination collision avoidance condition, the time of coordination collision avoidance of the two vehicles and the expected speed are calculated, and are transmitted to other coordination collision avoidance vehicles, thereby achieving a purpose that the vehicles at the same lane achieve the expected speed in a collision time range and move at a constant speed, and achieving the coordination collision avoidance.

Description

Technical field [0001] The invention belongs to the field of vehicle active safety, and in particular relates to a system and method for multi-vehicle coordinated collision avoidance in a vehicle-to-vehicle communication environment, which realizes the collision avoidance of a target vehicle through cooperation between vehicles. Background technique [0002] With the development of social economy, the number of cars and highway mileage have increased rapidly. Correspondingly, the number of deaths in traffic accidents on expressways remains high, especially the losses caused by serial traffic accidents, which have attracted more and more attention from the society and traffic management departments. The emergence of the Internet of Vehicles can realize the interaction of vehicle information, so that drivers have a longer time to take measures to avoid danger. It can be said that the application of the Internet of Vehicles provides technical support for the realization of coordina...

AI Technical Summary

Problems solved by technology

[0005] (1) Using traditional autonomous sensors, the information perception is not comprehensive and the timeliness is poor;

[0006] (2) The two vehicles did not consider the impact of the two vehicles on the surrounding vehicles during the collision avoidance process;

[0007] (3) In a multi-vehicle environment, the active safety effect of the vehicle cannot be fully exerted
