The invention discloses a high-voltage interlocking fault detection and processing method and system, and relates to the technical field of electric automobiles, and the method comprises the steps: obtaining the driving state of a vehicle after a high-voltage interlocking fault of a high-voltage part of the vehicle occurs; if the driving state is a driving state, judging the type of the high-voltage part with the high-voltage interlocking fault; and if the type of the high-voltage part with the high-voltage interlocking fault is a charging part, controlling the vehicle to keep full-power running. When the high-voltage part with the high-voltage interlocking fault is a charging part, the vehicle is controlled to run at full power, normal running of the vehicle can be prevented from being affected, and driving safety risks caused by sudden power interruption are avoided.

    本发明公开了一种高压互锁故障检测与处理方法及系统,涉及电动汽车技术领域,所述方法包括:在车辆的高压零部件发生高压互锁故障后,获取车辆的驾驶状态;若驾驶状态为行驶状态,则判断发生高压互锁故障的高压零部件的类型;若发生高压互锁故障的高压零部件的类型为充电部件,则控制车辆保持满功率行驶。本发明在发生高压互锁故障的高压零部件为充电部件时,控制车辆保持满功率行驶,可避免影响车辆的正常行驶,避免因动力突然中断带来的驾驶安全风险。
