Abstract
When a vehicle is switched from a two-wheel-drive mode to a four-wheel-drive mode during turning, rotation of a Rr dog clutch is synchronized by a synchro mechanism. Rotation of a Fr dog clutch is synchronized, by controlling coupling torque of a control coupling that transmits power to a rear wheel that provides an outer wheel during turning. Thus, rotation of the Fr dog clutch is also synchronized, so that shock at the time of engagement of the Fr dog clutch can be suppressed.
