Abstract

An engine control section () is configured to: start power supply to pinion-gear moving sections () based on an engine rpm which becomes smaller than an rpm at which the meshing engagement is possible while the engine is rotating by inertia as a result of satisfaction of an automatic stop condition; temporarily stop the power supply to the pinion-gear moving sections when an amount of change in the rpm of the engine exceeds a predetermined increase detection threshold value before time required for a pinion gear () to come into abutment against a ring gear () elapses after the start of the power supply; and restart the power supply to the pinion-gear moving sections when the amount of change in the rpm of the engine becomes smaller than a predetermined decrease detection threshold value after the power supply is temporarily stopped.
