A control device for a vehicle including an engine, the engine including an electric VVT mechanism, the electric VVT mechanism that changes a valve timing of at least either one of an intake valve and an exhaust valve, the control device includes an ECU. The ECU is configured to: perform a crankshaft stop position control to control a rotation stop position of a crankshaft during a stop process of stopping the engine, such that a valve opening degree in which at least either one of a first gap between the intake valve and the corresponding valve seat and a second gap between the exhaust valve and the corresponding valve seat is fully closed or becomes a predetermined gap or more is set as a target valve opening degree; and operate the electric VVT mechanism until the valve opening degree reaches the target valve opening degree, when the engine stops.
A control device for a vehicle, the vehicle including an engine, the engine including an intake valve, an exhaust valve, a first valve seat corresponding to the intake valve, a second valve seat corresponding to the exhaust valve, a crankshaft, a camshaft and an electric variable valve timing mechanism, the electric variable valve timing mechanism being configured to change a rotational phase of the camshaft relative to the crankshaft so as to change a valve timing of at least either one of the intake valve and the exhaust valve, the control device comprising:
