The invention discloses a vehicle and a high-voltage interlocking system thereof. The high-voltage interlocking system comprises a vehicle control unit, a plurality of high-voltage components and a plurality of voltage monitoring chips arranged in one-to-one correspondence with the high-voltage components. Each high-voltage component comprises a high-voltage connector and a low-voltage connector, in each high-voltage component, each high-voltage connector is electrically connected with an interlocking voltage output end of the vehicle control unit through the corresponding low-voltage connector to form an interlocking loop, and the voltage monitoring chips are connected in the interlocking loops of the high-voltage components in series in a one-to-one correspondence manner; the voltage monitoring chip is used for acquiring the voltage signal of the interlocking loop in real time and determining the interlocking state of the high-voltage components according to the voltage signal, when it is determined that a certain high-voltage component has a fault, troubleshooting is not needed one by one, the interlocking fault maintenance efficiency of all the high-voltage components is greatly improved, and the maintenance cost is reduced. And the voltage monitoring chip can be configured to adopt a relatively accurate fault detection method, so that misjudgment can be effectively avoided, and the method is simple in principle, reliable and feasible.

    本发明公开了一种车辆及其高压互锁系统,包括整车控制器、多个高压部件、以及与多个高压部件一一对应设置的多个电压监测芯片;高压部件包括高压连接器和低压连接器,在各高压部件中,高压连接器通过低压连接器与整车控制器的互锁电压输出端电连接构成互锁回路,各电压监测芯片一一对应的串联连接于各高压部件的互锁回路中;电压监测芯片用于实时获取互锁回路的电压信号,并根据电压信号确定高压部件的互锁状态,当确定某一个高压部件存在故障时,不需逐一进行排查,大幅提高了各高压部件的互锁故障检修效率,并且电压监测芯片可被配置为采用较为精确的故障检测方法,能够有效避免误判的情况发生,方法原理简单,可靠可行。
