PROBLEM TO BE SOLVED: To provide an engine starter control unit capable of grasping the moving speed of a pinion gear 52 without including a sensor directly detecting the moving speed of the pinion gear 52.SOLUTION: An inductance of a solenoid coil 42 is calculated on the basis of a voltage applied to the solenoid coil 42 and a variation in the value of a current flowing in the solenoid coil 42. A position of a pinion gear 52 is calculated on the basis of the calculated inductance, and a moving speed of the pinion gear 52 is calculated on the basis of the calculated position of the pinion gear 52. The current flowing in the solenoid coil 42 is manipulated so as to control the calculated moving speed. |
