| description | The present invention provides a clutch control device of a four-wheel drive vehicle in which it is possible to shorten the time for transitioning from a two-wheel drive mode to a four-wheel drive mode when moving uphill, and to improve the stability of transmitting drive force to the road surface. Therefore, the present invention is a clutch control device of a four-wheel drive vehicle, characterized in that a 4WD control unit (34) controls the engagement and disengagement of a dog clutch (8) and an electrically controlled coupling (16) which are arranged separately in a drive branch-side transmission system path and an auxiliary drive wheel-side transmission system path that sandwich a rear differential (15), in a system for transmitting drive force to left and right rear wheels (19, 20), wherein the 4WD control unit comprises, as two-wheel drive modes, a disconnected two-wheel drive mode in which the dog clutch (8) and the electrically controlled coupling (16) are released, and a standby two-wheel drive mode in which the dog clutch (8) is engaged and the electrically controlled coupling (16) is released; and a switch to the standby two-wheel drive mode is carried out when uphill movement is detected during the disconnected two-wheel drive mode. |
