Vehicle active collision avoidance system based on VII support

Abstract

The invention discloses a vehicle active collision avoidance system based on VII support, comprising a short-distance wireless communication terminal, a road side base station and a traffic information service center, wherein, the short-distance wireless communication terminal is installed in a vehicle; the vehicle-mounted short-distance wireless communication terminals of the vehicles in local road sections form a wireless communication local area network; a road side base is arranged at a road side, various sensors arranged on the vehicle obtains the data information through uploading and collecting by CAN buses; the short-distance wireless communication terminal is provided with a danger warning information publisher; when the dangerous condition such as potential rear-end collision and the like exists, the danger warning information publisher is activated; the danger warning information is published in a broadcast manner through the short-distance wireless communication; after the short-distance wireless communication terminals on other vehicles receive the danger warning information, a central controller safety status judgment module analyzes the critical following distance required in preventing rear-end collision with abnormal running vehicles in a current running state. The vehicle active collision avoidance system of the invention can effectively reduce time delay and improve reliability.

Description

technical field [0001] The invention relates to a vehicle active collision avoidance system. Background technique [0002] In recent years, highway traffic accidents remain high, among which rear-end collision accidents account for more than 75%. The development of high-performance vehicle active collision avoidance system has become an urgent need to improve the active safety performance of vehicles during high-speed driving and reduce the incidence of rear-end collision accidents. [0003] The vehicle active collision avoidance system uses modern information technology and sensor technology to detect potential dangers such as rear-end collisions during vehicle driving, and automatically takes collision avoidance measures in emergency situations to ensure vehicle driving safety. The rapid detection of abnormally driving vehicles ahead is the basis for the realization of the vehicle active collision avoidance system, and the determination of the critical following distance ...
