Abstract

A starter includes an electromagnetic solenoid that generates force for pushing a pinion gearto a ring gear side, and an electromagnetic switch that opens and closes a motor contact point. When idle-stop is performed, an ECU energizes a solenoid coil of the electromagnetic solenoid during inertial rotation until the ring gear stops rotating. After rotation of an engine is stopped, the ECU stops energizing the solenoid coil. As a result, in the starter, the pinion gear can mesh with the ring gear that is rotating by inertia without use of the rotational force of a motor. The meshed state can be maintained even after energization of the solenoid coil is stopped.
