Embodiment Construction

[0043] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0044] see figure 1 The vehicle collision early warning and active control method based on the vehicle-vehicle communication proposed in the embodiment is realized by an early warning control device installed on the vehicle. An environment perception unit 20 , an alarm unit 30 , a vehicle control unit 40 , and a vehicle-to-vehicle communication unit 50 . Wherein, the vehicle-to-vehicle communication unit 50 can be wirelessly connected with adjacent vehicles (including the front vehicle, the rear vehicle, or adjacent vehicles on both sides of the vehicle); The data processing unit 10 judges whether there is a collision risk in conjunction with the environment perception and state data of the vehicle and the adjacent vehicle environment perception and state data received from the vehic...

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 ...
