Control apparatus and method for internal combustion engine

摘要

A control apparatus and method for an internal combustion engine are provided for preventing a sudden increase in rotational speed of the internal combustion engine associated with a release of braking when a driven object is braked during the execution of a feedback control, thereby ensuring high drivability. The control apparatus controls an internal combustion engine equipped in a driven object as a power source. The control apparatus comprise an ECU for setting the detected rotational speed of said internal combustion engine as the target rotational speed at all times when braking is executed by a brake during the feedback operation, and the rotational speed of said internal combustion engine is less than a predetermined threshold value, and for gradually increasing the target rotational speed until the target rotational speed reaches the predetermined target rotational speed after the breaking by the brake is released.
