Abstract
A ring gear is connected to a crank shaft of an engine. A pinion is placed to face to the ring gear. When the engine is started, an ECU performs cranking of the engine under a state where the ring gear and the pinion are in mesh. The ECU releases the mesh state of the ring gear and the pinion after completion of the cranking of the engine. In particular, the ECU performs dispersion control to increase a degree of dispersion of a mesh portion of the ring gear which is meshed with the pinion when the rotation of the ring gear is stopped according to the engine stop. The dispersion control prevents the mesh portion of the ring gear and the mesh portion of the pinion from progressing abrasion and avoiding defect.
