The present invention reduces power consumption when an engine is started by an electric motor and also reduces the starting time required to start the engine. Engine start control is implemented as follows. In steps S1 to S4, the RPM of the engine is increased to an RPM (R1) by means of the electric motor. In steps S5 to S7, fuel is supplied to the engine which has reached the RPM (R1) and further increases in the RPM of the engine are detected. In step S8, if a further increase in the RPM of the engine is detected, the supply of power to the electric motor is temporarily interrupted. In steps S9 to S11, if the RPM of the engine has decreased to an RPM (R2), the supply of fuel to the engine is interrupted and also the supply of power to the electric motor is resumed. If a further increase in the RPM of the engine is detected or the RPM of the engine has not decreased to the RPM (R2), it is determined that the engine has been started.
