The invention provides a vehicle side collision early warning method and system, and the method comprises the steps: collecting the relative distance and speed information of a target vehicle at the side of a vehicle based on a vehicle-mounted millimeter wave radar and a laser blind compensation radar; if the relative distance of the target vehicle reaches a first set value and the speed of the target vehicle is greater than a preset vehicle speed, carrying out early warning prompt on the vehicle; if the target vehicle continuously gets close to the vehicle, the relative distance of the target vehicle reaches a second set value, and the speed of the target vehicle is larger than the preset speed, the vehicle is controlled to be braked and decelerated; and after braking deceleration, if the relative distance of the target vehicle reaches a third set value and the speed of the target vehicle is greater than the preset vehicle speed, controlling the vehicle to lift a chassis close to the side of the target vehicle through the suspension system. By means of the scheme, the side face coming vehicles can be accurately detected, accurate early warning can be conducted on the side face coming vehicles, and injuries caused by side face collision to passengers in the cabin can be effectively avoided.

    本发明提供一种车侧碰撞预警方法及系统,该方法包括:基于车载毫米波雷达和激光补盲雷达,采集自车侧面目标车辆相对距离和速度信息;若目标车辆相对距离达到第一设定值,且目标车辆速度大于预定车速,则对自车进行预警提示;若目标车辆持续靠近自车,且目标车辆相对距离达到第二设定值,目标车辆速度大于预定车速,则控制自车制动减速;当制动减速后,若目标车辆相对距离达到第三设定值,且目标车辆速度大于预定车速,则通过悬架系统控制自车抬升靠近目标车辆侧的底盘。通过该方案不仅可以准确检测侧面来车,并对侧面来车进行准确预警,而且能够有效避免侧面碰撞对座舱乘客产生的伤害。
