The invention discloses a rear-end collision prevention method, which comprises the following steps of: detecting the relative speed and the actual relative distance between a vehicle and a front vehicle through a millimeter wave radar and an ultrasonic radar, calculating the collision time, and when the collision time or the actual relative distance is smaller than a set value, performing sound-light alarm. And the deceleration value is obtained by looking up the table according to the collision time and the actual relative distance, and the vehicle is decelerated and braked according to the deceleration value, so that rear-end collision accidents are avoided.

    本发明公开了一种防追尾方法,该方法通过毫米波雷达和超声波雷达检测自车与前车的相对速度和实际相对距离,并计算碰撞时间,当碰撞时间或实际相对距离小于设定值时,进行声光报警,且按照碰撞时间与实际相对距离查表得到减速度值,车辆根据减速度值进行减速制动,避免了追尾事故的发生。
