摘要:
An engine starting system for an engine is equipped with a pinion, an electromagnetic actuator, and a controller. When energized, the electromagnetic actuator produces a magnetic attraction to move the pinion straight toward a ring gear coupled to an engine for starting the engine. The controller is designed to selectively provide a small amount of current to the electromagnetic actuator and a large amount of current to the electromagnetic actuator. When it is required to minimize the level of noise arising from mechanical contact of the pinion with the ring gear, the controller provides the small amount of current to the electromagnetic actuator to slow the movement of the pinion toward the ring gear, thereby lessening the impact of the pinion on the ring gear.
