The invention relates to a passenger car rear collision early warning system which comprises a BSD radar, an outer rearview mirror indicator light, an MP5 switch and a combination instrument. The BSD radar is installed in a bumper at the tail of a vehicle and used for detecting targets in the rear area of the vehicle and collecting corresponding data, and the outer rearview mirror indicator light is used for reminding a driver of the collision risk; the MP5 switch is used for controlling on and off of a rear collision early warning function RCW and displaying RCW alarm information; and the combination instrument is used for giving out an alarm sound, displaying related state indication and self-inspection fault information, and controlling the lightening of the double flash and the brake lamp through the body control module BCM. The two 77GHz millimeter wave radars installed at the left end and the right end of the car bumper are used for detecting targets in the area behind the car and collecting related data, when it is judged that the rear-end collision risk exists, a driver of the car is warned through the outer rearview mirror LED indicator lamps, the double flash is turned on at the same time, a driver close to the rear of the car is warned, and therefore rear-end collision accidents are avoided.
本发明涉及一种乘用车后碰撞预警系统,包括BSD雷达、外后视镜指示灯、MP5开关和组合仪表;所述BSD雷达安装在车辆尾部的保险杠内,用于探测车辆后方区域内的目标并采集相应数据,所述外后视镜指示灯用于提示驾驶员有碰撞风险;所述MP5开关用于控制后碰撞预警功能RCW的开闭并显示RCW报警信息;所述组合仪表用于发出报警音、显示相关状态指示和自检故障信息,并通过车身控制模块BCM控制双闪及刹车灯的点亮。本发明通过两个安装在车辆保险杠左右两端的77GHz毫米波雷达探测车辆后方区域内的目标物并采集相关数据,在判定有追尾风险时通过外后视镜LED指示灯,警示本车驾驶员,同时打开双闪,警告后方接近车辆的驾驶员,从而避免追尾事故的发生。
