The invention belongs to the field of traffic safety, and particularly relates to a highway vehicle anti-collision early warning system. The system specifically comprises a safe vehicle distance keeping subsystem, a brake signal identification subsystem and a deceleration brake early warning subsystem. On one hand, when the actual vehicle distance between the two vehicles is smaller than the theoretical safety vehicle distance at the actual vehicle speed of the target vehicle, the system sends out a safety early warning signal, and then the system gives an alarm to remind a driver to decelerate, which is realized through the safety vehicle distance keeping subsystem and the deceleration braking early warning subsystem. When a traffic accident occurs in front of the road, a vehicle in front of the lane line starts to decelerate and brake emergently or the vehicle in front frequently decelerates, brakes and accelerates when the vehicle in front is congested, the system gives an alarm to remind a driver of the target vehicle to decelerate or brake earlier, and the driver is prevented from being damaged. And the risk of collision during emergency braking due to too late deceleration braking time is reduced, which is realized through the braking signal identification subsystem and the deceleration braking early warning subsystem.

    本发明属于交通安全领域,具体涉及一种高速公路车辆防撞预警系统。本发明具体包括:安全车距保持子系统、制动信号识别子系统、减速制动预警子系统。一方面,两车之间实际车间距小于目标车辆实际车速下的理论安全车距,系统将发出一个安全预警信号,然后系统发出警报,提醒驾驶员减速,这将通过安全车距保持子系统和减速制动预警子系统实现。当道路前方发生交通事故该车道线前方车辆开始紧急减速制动或该车道通行车辆拥堵时前方车辆频繁进行减速、制动和加速操作时,系统发出警报,提醒目标车驾驶员更早地作出减速或制动行为,降低因减速制动时机太晚而紧急制动时发生碰撞的风险,这将通过制动信号识别子系统和减速制动预警子系统实现。
