Control device and control method of a starter, and engine starting device
First Claim
1. A control device of a starter that includes a second gear that can be engaged with a first gear coupled to a crankshaft of an engine, an actuator that moves said second gear to a position of engagement with said first gear in a driven state, a helical spline that makes said second gear rotate in a reverse direction while said second gear moves toward said first gear, and a motor that rotates said second gear, said control device being capable of individually driving each of said actuator and said motor, comprising:
- drive means for driving said actuator prior to drive of said motor; and
stop means for stopping drive of said actuator when an output shaft of said engine rotates in a reverse direction, after said actuator was driven and before said motor is driven.

Abstract
A starter includes a pinion gear that can be engaged with a ring gear provided around an outer circumference of a flywheel or a drive plate of an engine, an actuator for moving the pinion gear to a position of engagement with the ring gear in a driven state, a helical spline for rotating the pinion gear in a reverse direction while the pinion gear moves toward the ring gear, and a motor for rotating the pinion gear. The actuator and the motor are individually controlled. After the actuator was driven and before the motor is driven, drive of the actuator is stopped.

5. A control method of a starter that includes a second gear that can be engaged with a first gear coupled to a crankshaft of an engine, an actuator that moves said second gear to a position of engagement with said first gear in a driven state, a helical spline that makes said second gear rotate in a reverse direction while said second gear moves toward said first gear, and a motor that rotates said second gear, each of said actuator and said motor being able to individually be driven, comprising the steps of:
-
driving said actuator prior to drive of said motor; and stopping drive of said actuator when an output shaft of said engine rotates in a reverse direction, after said actuator was driven and before said motor is driven. - View Dependent Claims (6, 7, 8)
