At this time, the power from the battery 70 is supplied to the motor driver and converted from direct current to three-phase alternating current. Electric power from the battery 70 is supplied to the generator 13 after being converted into three-phase alternating current.

After the engine 11 is started, the ACG-ECU 71 controls the generator 13 to function as a generator when the engine 11 is in operation (when the generator 13 generates power). The FI-ECU 72 controls the operation of the engine 11 by controlling ignition timing, fuel injection amount, and the like according to the throttle opening and the like. The electric power generated by the generator 13 passes through the rectifier circuit of the ACG-ECU 71 and the like, and is stored in the battery 70, which is an on-vehicle power supply.
