Abstract
A control device for an internal combustion engine and a control method for a variable mechanism for an internal combustion engine for a vehicle, according to the present invention, is configured to maintain a drive stopped state of an electric actuator of the variable mechanism when a position of the electric actuator does not change in a case in which the position of the electric actuator is apart from stoppers and the electric actuator is stopped, whereas to restart driving the electric actuator when the position of the electric actuator changes. In this way, it is possible to prevent wasteful power consumption while the internal combustion engine is stopped.
