The invention relates to a protection method, device and system for coping with rear-end collision of a rear vehicle and a storage medium. The method comprises the following steps: acquiring relative speed, relative acceleration and relative distance information with a rear vehicle by using a radar and a sensor; receiving the information through at least one processor, calculating and analyzing according to a preset algorithm, and judging whether a rear-end collision risk exists or not; if the rear-end collision risk exists, the processor further judges whether the collision energy of the rear vehicle exceeds an energy threshold value set in the processor or not; if the collision energy does not exceed the collision energy threshold value, only controlling a danger warning signal lamp to flicker; if the collision energy exceeds the collision energy threshold value, a signal is sent out through the processor, so that the ejection device is ejected, and the rear-end collision protection device is quickly put down; and a danger warning signal lamp is controlled to flicker, and an emergency rescue call is dialed. When the rear-end collision energy is judged to possibly cause serious damage of passenger casualties of the rear vehicle, the rear-end collision protection device is put down, the head of the rear-end vehicle is guided to be lifted upwards, and the upper portion of a passenger compartment is prevented from being directly collided.
本发明涉及一种应对后车追尾的防护方法、装置、系统和存储介质;方法包括:利用雷达及传感器采集与后车的相对速度、相对加速度、相对距离信息;通过至少一个处理器接收所述信息,并根据预设算法计算分析,判断是否存在追尾风险;若存在追尾风险,处理器进一步判断后车的撞击能量是否超过处理器中设定的能量阈值;若未超过碰撞能量阈值,则仅控制危险警告信号灯闪烁;若超过碰撞能量阈值,则通过处理器发出信号,使弹射装置弹出,将追尾防护装置快速放下;控制危险警告信号灯闪烁,并拨打紧急救援呼叫。本发明判断追尾碰撞能量可能导致后车发生乘员伤亡的严重受损时,放下追尾防护装置,引导追尾车辆车头向上抬起,避免乘员舱上部受到直接撞击。
