  • Patent number: 9382891
    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.

  • Publication number: 20160003182
    Abstract: A control device is provided which prevents a temperature increase within an ECU by suppressing heat generation in the ECU without using a new cooling device such as a blow fan. In one step, an open valve voltage target value is calculated. An open valve voltage is a voltage applied to a fuel injection valve when opening the fuel injection valve. As the number of times of the multi-stage injections increases, an opportunity to boost the open valve voltage increases, heat is generated in the open valve voltage boosting section, a temperature within the ECU excessively increases, and there is a concern that an electronic component within the ECU malfunctions or fails. Thus, a temperature sensor is provided on an inside of the ECU and if an ECU temperature is high, it is determined that heat is generated in the open valve voltage generating section and the open valve voltage target value is reduced.

  • Publication number: 20140196681
    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.
