The invention belongs to the field of motor vehicle driving safety, and discloses an early warning system and method for preventing rear-end collision when roadside vehicles avoid pedestrians. The early warning system comprises a pedestrian detection millimeter wave radar and a vehicle detection millimeter wave radar which are electrically connected with the signal input end of a controller, and an LED warning lamp and a voice device which are electrically connected with the signal output end of the controller. The early warning system can determine the collision risk of a front vehicle and a pedestrian and the rear-end collision risk of the front vehicle and a rear vehicle according to parameter information acquired by the pedestrian detection millimeter wave radar and the vehicle detection millimeter wave radar and information preset in the controller. The road side LED warning lamp and the voice device are used for carrying out graded early warning on pedestrians and rear vehicle drivers, the early warning method solves the problem that the risks of pedestrian collision and rear-end collision occur at the same time, safety is high, and reliability is high.

    本发明属于机动车行驶安全领域,公开了一种路侧车辆避让行人时防追尾碰撞预警系统及方法,该预警系统包括分别与控制器的信号输入端电连接的行人检测毫米波雷达和车辆检测毫米波雷达,以及分别与控制器的信号输出端电连接的LED警示灯和语音装置;该预警系统可以根据行人检测毫米波雷达和车辆检测毫米波雷达获取的参数信息以及控制器内预先设置的信息确定前车与行人的碰撞风险以及前车与后方车辆的追尾风险,并通过路侧LED警示灯和语音装置向行人和后方车辆驾驶人进行分级预警,其预警方法解决了行人碰撞与追尾碰撞风险同时出现的问题,安全性高,可靠性强。
