Abstract
A starter includes a pinion gear, an actuator for moving the pinion gear to a position where the pinion gear is engaged with a ring gear in a driven state, and a motor for rotating the pinion gear. An ECU includes a rotation mode in which the motor is driven before the actuator is driven and an engagement mode in which the actuator is driven before the motor is driven. In the engagement mode, the actuator is driven after lapse of a predetermined first time period since a decision to start an engine was made, and the motor is driven after lapse of a second time period longer than the first time period since the decision to start the engine was made. In the rotation mode, the motor is driven after lapse of the second time period since a decision to start the engine was made.
