The invention relates to a high-voltage interlocking protection system and an automobile, the high-voltage interlocking protection system comprises a fault diagnosis subsystem and a plurality of high-voltage interlocking loops, and the fault diagnosis subsystem is used for acquiring a detection result corresponding to each high-voltage interlocking loop in the plurality of high-voltage interlocking loops; determining all fault high-voltage interlocking loops with high-voltage interlocking faults in the plurality of high-voltage interlocking loops based on all detection results; and determining a high-voltage interlocking protection scheme according to the running state of the target vehicle and all the fault high-voltage interlocking loops. According to the invention, under the condition that the high-voltage interlocking fault occurs, the corresponding high-voltage interlocking protection scheme can be generated aiming at the fault high-voltage interlocking loop with the fault and considering the current running state of the target vehicle, so that the protection scheme can be applied to the current state of the target vehicle, and the safety of the target vehicle is improved. And safe operation of the target vehicle can be guaranteed under the condition that the high-voltage interlocking fault occurs.

    本发明涉及一种高压互锁保护系统以及汽车,其中,高压互锁保护系统包括:故障诊断子系统以及多个高压互锁回路,故障诊断子系统用于:获取与多个高压互锁回路中的每个高压互锁回路对应的检测结果;基于所有检测结果确定出多个高压互锁回路中存在高压互锁故障的所有故障高压互锁回路;按照目标车辆的运行状态以及所有故障高压互锁回路,确定出高压互锁保护方案。本发明可以在发生高压互锁故障的情况下,能够针对发生故障的故障高压互锁回路,以及考虑到目标车辆当前的运行状态,来生成对应的高压互锁保护方案,进而可以使该保护方案适用于目标车辆当前的状态,并且在发生高压互锁故障的情况下,也能够保障目标车辆的安全运行。
