Abstract
A starter to start an engine mounted on a vehicle provides an electromagnetic solenoid to push a pinion gear towards a ring gear side, an electromagnetic switch to open and close a motor contact point. The electromagnetic solenoid and the electromagnetic switch are individually controlled by an Electronic Control Unit i.e., ECU. When an idle-stop is triggered, the ECU controls a starter relay to be closed during the ring gear is rotating whereby the pinion gear together with a clutch are pushed out to counter-motor direction by the electromagnetic solenoid. As a result, the pinion gear meshes with the ring gear that is rotating at lower rotational speed. Therefore, the inertial mass of the starter is added to the ring gear so that swinging of the engine can be suppressed.
