A control device includes a differential rotation obtaining unit; a direct-coupling control unit that decreases the differential rotation speed by increasing an engagement pressure of the direct-coupling clutch at a normal pressure increase rate determined depending on a traveling state of a vehicle so as to change the direct-coupling clutch from a released state to an engaged state; and a pressure increase control unit that changes to a rapid pressure increase rate larger than the normal pressure increase rate for increasing the engagement pressure by the direct-coupling control unit when the differential rotation speed becomes equal to or smaller than a predetermined pressure increase permission threshold in a state that an accelerator opening of the vehicle decreases.
