A first control unit executes a valve stop inertial running including stopping an intake valve and an exhaust valve in a closed state during rotation of an output shaft, stopping supply of fuel to an engine, and setting a clutch in an engaged state to drive pistons of the engine by a rotational force from driving wheels. A second control unit executes a valve operation running including operating the intake valve and the exhaust valve during the rotation of the output shaft, and supplying the fuel to the engine based upon an intake conduit pressure. When a cancellation request is made during execution of the valve stop inertial running, a transient control unit operates the intake valve and the exhaust valve, and controls a throttle valve to an idling opening or less, thereby supplying a negative pressure to an intake passage.
