Upon gear disengagement, a pinion gear drive means actuates a pinion gear to disengage from a ring gear while the starter motor of a starting device is rotated or while injectors of an engine are caused to inject fuel into cylinders of the engine to ignite an air-fuel mixture therein, thereby releasing the gear disengagement. Applied to an idling stop-capable vehicle that engages the starter pinion gear with the engine ring gear beforehand to shorten the time to restart, the inventive control apparatus with the above feature releases unfailingly the engagement against metal-to-metal frictional force that causes the gears to be stuck with each other upon engine stop.
An engine control apparatus comprising a ring gear for transmitting torque to an engine, a starting device for starting said engine, a pinion gear supported on an output rotation shaft of a starter motor of said starting device, and a pinion gear drive means for sliding said pinion gear on said output rotation shaft, said engine control apparatus being equipped with an idling stop function to stop said engine during engine idling, said engine control apparatus further performing control to engage said ring gear and said pinion gear with each other in an idling stop state;
