Cooperative anti-collision device based on vehicle-vehicle communication and anti-collision method

Abstract

The invention provides a cooperative anti-collision device based on vehicle-vehicle communication, belonging to the technical field of intelligent transportation/automobile safety control. The device comprises a vehicle operation information acquisition unit, a vehicle-vehicle communication unit, an information processing control unit, a data storage unit, an alarm unit and an execution unit. The vehicle operation information acquisition unit comprises a wheel speed sensor and a ranging module. Through the invention, the safety guarantee in vehicle running is enhanced; however, each vehicle executing cooperative collision prevention needs to be additionally provided with a cooperative anti-collision device, and a single vehicle only can implement the functions of a common anti-collision device; the vehicle-vehicle communication unit can acquire the information of space, speed and the like of the vehicles around in real time and perform real-time information interaction with the vehicles around; when the space is less than the safe space, the information processing control unit of the rear vehicle calculates the expected deceleration to avoid collision by reducing speed; and if the collision can not be prevented only by the rear vehicle, acceleration allocation information is sent to the front vehicle to notify the front vehicle to accelerate for cooperative collision prevention.

Description

technical field [0001] The invention belongs to the technical field of intelligent traffic / automobile safety control, and in particular relates to a cooperative collision avoidance device and a collision avoidance method for solving collision accidents caused by too close a vehicle distance during vehicle driving. Background technique [0002] With the development of modern transportation and the continuous development of the automobile industry, the construction of expressways in our country has developed rapidly in recent years, followed by the frequent occurrence of traffic accidents. On the expressway, in the event of bad weather, poor road conditions, traffic jams or driver fatigue, it is very easy for cars to collide, head-on collisions or even serial traffic accidents. This poses a great threat to the safety of people's lives and property, and also highlights the necessity and urgency of developing intelligent active safety systems for automobiles. A European study s...
