Abstract:
A control apparatus that controls a four-wheel drive vehicle in which a driving force is transmitted to rear wheels via a dog clutch, a propeller shaft, and a driving force transmission apparatus is configured to, when switching to a four-wheel drive mode, reduce a difference in rotation speeds of an intermediate rotational member and a ring gear member by a frictional force between a friction surface of a friction member, which is configured such that its rotation relative to the intermediate rotational member is restricted, and a target frictional slide surface of the ring gear member, and then couple the intermediate rotational member and the ring gear member by a clutch member in a state in which engagement forces of friction clutches configured to transmit the driving force between each of first and second output rotational members and the intermediate rotational member of the driving force transmission apparatus are set to engagement forces that allow their relative rotation.

Claim (Index 3):
The control method for a four-wheel drive vehicle according to  claim 2 , wherein\n the movement mechanism is configured to move the clutch member and the friction member by pressing the clutch member and the friction member by a single pressing member that is movable in an axial direction along a rotation axis of each of the first rotational member and the second rotational member, and the frictional force is generated through a movement of the pressing member to one side in the axial direction to reduce the difference in the rotation speeds of the first rotational member and the second rotational member, and then the clutch member is moved to the coupled position through a further movement of the pressing member to the one side in the axial direction.
