The invention discloses a rear-end collision prevention system based on a millimeter-wave radar. The millimeter-wave radar is arranged around a vehicle body to detect and obtain vehicle condition information around the vehicle body; a vehicle body CAN network receives vehicle condition information around a vehicle body and sends the vehicle condition information to a vehicle system master controller; the vehicle system master controller judges whether safe emergency steering can be carried out or not by combining the vehicle condition information around the vehicle body and the vehicle information; if the safe emergency steering can be carried out, a steering control signal is generated and sent to the steering control module; and the steering control module controls a steering wheel of the vehicle to conduct emergency steering according to a steering control signal sent by the vehicle system master controller so as to prevent rear-end collision. Aiming at the accident that a small vehicle in the middle position is extruded to be flat due to the fact that a current intelligent driving safety system neglects rear-end collision of rear vehicles, measures of alarming and emergency steering are adopted to reduce or avoid the risk.
本发明公开了一种基于毫米波雷达的防追尾系统。毫米波雷达布置在车身周围,探测获得车身周围车况信息;车身CAN网络接收车身周围车况信息发送到车辆系统主控;车辆系统主控结合车身周围车况信息和自身车辆信息判断出是否能够进行安全的紧急转向:能进行安全紧急转向则产生转向控制信号并发送到转向控制模块;转向控制模块根据车辆系统主控发过来的转向控制信号控制车辆的方向盘进行紧急转向,以防止防追尾。本发明针对目前智能驾驶安全系统忽视了后方车辆追尾撞击而造成处于中间位置的小型车被挤扁的事故,采用了报警和紧急转向的措施减轻或规避了此类风险。
