The invention discloses a vehicle collision safety protection system and method, a vehicle and a medium. The vehicle collision safety protection system comprises a first protection switch unit which is arranged in a high-voltage loop of a power battery; the second protection switch unit is connected to the positive electrode of the power battery in series; the at least one collision detection unit is used for detecting whether the vehicle collides or not; and the control unit is used for controlling the second protection switch unit to be switched off when the vehicle collides and controlling the first protection switch unit to be switched off so as to perform dual protection. According to the scheme, the first protection switch unit and the second protection switch unit are controlled to be switched off at the same time, under the condition that one switching-off mode fails, the other switching-off mode can achieve the purpose of cutting off high voltage, the success rate of cutting off the high voltage is improved, and therefore the safety of a vehicle is guaranteed.

    本发明公开了一种车辆碰撞安全保护系统、方法、车辆和介质。所述车辆碰撞安全保护系统,包括:第一保护开关单元,第一保护开关单元设置在动力电池的高压回路中;第二保护开关单元,第二保护开关单元串联连接在动力电池的正极;至少一个碰撞检测单元,用于检测车辆是否发生碰撞;控制单元,用于在车辆发生碰撞时控制第二保护开关单元断开,并控制第一保护开关单元断开,以进行双重保护。采用本方案通过同时控制第一保护开关单元和第二保护开关单元断开,能够在其中一种断开方式失效的情况下,另外一种断开方式也能达到切断高压的目的,提高了切断高压的成功率,从而保证了车辆的安全。
