Abstract
Each of a first clutch and a second clutch is, for example, an electromagnetic clutch that is operated by an electromagnetic actuator, and is supplied with electric power from the same in-vehicle battery as a starter motor of an engine. An electronic control unit is configured to not change a drive mode during a stop of the engine, and, after a predetermined period has elapsed from a start of operation of the starter motor at a startup of the engine (for example, the startup has completed) and a battery voltage has been recovered, change the drive mode to any one of a two-wheel drive mode and a four-wheel drive mode with the first clutch and the second clutch.
