Specifically, the fault processing module 9 outputs the upper high-voltage signal or lower high-voltage signal of the whole vehicle and the control signal of the load to the signal output module 11 when it determines that the upper high-voltage signal or lower high-voltage signal of the whole vehicle and the control signal of the load received by it are faulty. The fault processing module 9 outputs a fault signal to the signal output module 11 when it determines that the upper high-voltage signal or lower high-voltage signal of the whole vehicle and the control signal of the load received by it are faulty. The signal output module 11 outputs the upper high voltage signal or the lower high voltage signal of the vehicle, the control signal of the load, the torque signal, the gear position signal that the vehicle needs to execute, and the fault signal to the underlying software layer 12 and the underlying hardware layer 13.
