PURPOSE:To realize safety reset to normal operation by mutually monitoring the operation of CPU regardless of the state of loop and the like. CONSTITUTION:A vehicle controller 12 and a motor controller 14 monitor data stored in their memories 24, 26 and in case of clear data, a decision is made that the counterpart controller 14 or 12 is abnormal and then supply of PWM signal to the inverter 12 is interrupted. According to the invention, safety reset to normal operation is realized. |
