The control unit keeps the control valve in a first state while a temperature of oil circulated by the oil pump is lower than a predetermined value, and switches the control valve to a second state when the temperature of the oil circulated by the oil pump becomes not lower than the predetermined value while the control valve is in the first state. The control unit changes a voltage command value of an electric motor to a value smaller than a voltage command value corresponding to a required output of the electric motor after elapse of a predetermined period from a time the control valve is switched to the second state.
