Abstract
A control device of a vehicle engine comprises: an electric motor rotationally driving an engine to start the engine; a variable valve timing mechanism varying a valve timing of an intake valve of the engine; and an intermediate lock mechanism mechanically locking the valve timing at an intermediate position between a most delayed position and a most advanced position of the valve timing, if an output limitation of the electric motor is predicted at restart of the engine, the valve timing at the time of stop of the engine being locked at the intermediate lock position by the intermediate lock mechanism.
