Abstract: An engine control apparatus includes an engine control unit that is configured to control a ring gear, a starting device and a pinion gear. The engine control unit is further configured to perform a control to engage the ring gear and pinion gear with each other in an idling stop state, and to control a pinion gear driver. The pinion gear driver actuates the pinion gear to disengage from the ring gear. In particular, the pinion gear driver actuates the pinion gear to disengage from the ring gear while the ring gear is not rotated and while a starter motor of the 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, so as to release engagement of the pinion and ring gears.

Abstract: An automobile control device includes a function that can control drive torque of a starting device to an arbitrary value, and a positive rotation detecting unit having at least one of a function to detect whether an engine rotates positively and a function to detect whether the engine does not rotate reversely. The control device also has an idle stop function to increase the drive torque of the starting device when the positive rotation detecting unit detects that the engine rotates positively or does not rotate reversely. Accordingly, problems of malfunctions such as a reduction in a system voltage, abnormal wear of a brush in a starter motor, and breakage of a semiconductor switch are solved that are found in a conventional automobile control device having the idle stop function and that are caused by flowing of overcurrent when a starter is driven during swing-over that occurs immediately before engine stop.

Abstract: 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.

Abstract: When a request for re-start of an engine or a request for start occurs during inertial revolution of the engine by fuel cut at the time of request for idle stop, an operation of starting by re-start of fuel injection and an operation of driving the starter overlap, and a problem is likely to occur in wear resistance and durability of a ring gear and a pinion gear. Further, since collision torque becomes large, a collision sound of the ring gear and the pinion gear and a mesh sound which occurs at the instant of connection are likely to occur. The present invention changes a method of starter drive based on a behavior of engine revolution after a request for re-start of the engine or a request for start occurs during inertial revolution of the engine by fuel cut at the time of request for idle stop, and combustion recovery is implemented by an engine combustion recovery function, or an engine state or the like at the time of occurrence of change of mind, in a controller of a vehicle having an idle stop function.
