Vehicle collision warning and active control method based on vehicle communication

Abstract

The invention relates to a vehicle collision warning and active control method based on vehicle communication. The method is realized through an early warning control device which is arranged on a vehicle. A front vehicle collision warning and active control method, a rear vehicle tailgate warning and active control method and an adjacent vehicle lane changing warning and active control method are comprised. According to the invention, a vehicle communication collaborative way is used to exchange the environmental perception and state data of two vehicles; safety distance and brake device can be adjusted by integrating the conditions of the vehicle and an adjacent vehicle; warning delay of the vehicle and the adjacent vehicle is reduced; and the vehicle and the adjacent vehicle can collaborate to make a proper active vehicle control decision and operation. The problems that the information of the adjacent vehicle is unavailable; safety distance and brake device cannot be adjusted; and vehicle collaborative collision warning and collaborative active safety operation cannot be carried out for the state of the adjacent vehicle in the prior art relying on a collision avoidance system of the vehicle are solved. The reliability and the accuracy of vehicle collision and active control are effectively improved.

Description

technical field [0001] The invention relates to the technical field of vehicle collision prevention, in particular to a vehicle collision early warning and active control method based on vehicle-to-vehicle communication. Background technique [0002] Existing vehicles are generally equipped with active safety systems, such as forward-looking anti-collision systems, lane-changing anti-collision systems, etc., mostly through various sensors such as visual sensors, radar sensors, ultrasonic sensors, etc. Static and dynamic obstacles, moving objects in the blind spots on both sides of the vehicle, objects gradually approaching from the rear of the vehicle, etc., and then judge the safety of the vehicle according to the set parameters, and the control system executes the intelligent control behavior of the vehicle by itself, including deceleration, braking, Operations such as changing lanes and avoiding to achieve the goal of vehicle active safety control. [0003] However, the ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to propose a vehicle collision warning and active control method based on vehicle-to-vehicle communication, so as to solve the problem that the existing vehicle active safety system only relies on the self-vehicle anti-collision system, which cannot obtain the information of adjacent vehicles and cannot target the state of adjacent vehicles. Adjust the safe vehicle distance and brake device, and carry out vehicle-vehicle cooperative collision warning and cooperative active safety operation
