PURPOSE: To prevent an erroneous operation of a controller by providing first power source means for supplying a voltage to a starter motor and second power source means for holding a power source voltage of the controller.
CONSTITUTION: A power capacitor 34 is connected as first power source means to a main battery 10 through a DC/DC converter 20. Further, an auxiliary unit battery 22 as second power source means, and EV-ECU 36 and E/G-ECU 38 as controllers are connected to the battery 10 through a DC/DC converter 20. Accordingly, at the time of driving a starter motor 24, driving power of the motor 24 is mainly supplied from the capacitor 34. The power source voltages of the EV-ECU 35 and EGG-ECU 38 is held constantly by the battery 22. Thus, an erroneous operation of the controller can be prevented.
