The present invention provides a clutch control device of a 4-wheel drive vehicle in which it is possible to shorten the time for transitioning from a 2-wheel drive mode to a 4-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 4-wheel drive vehicle, characterized in that: a 4WD control unit (34) controls the engaging and disengaging of a dog clutch (8) and an electrically controlled coupling (16) which are arranged separately on either side of a rear differential (15) in a system for transmitting drive force to left and right rear wheels (19, 20), one of the dog clutch (8) and the electrically controlled coupling (16) being arranged in a transmission system path to a drive fork and the other being arranged in a transmission system path to auxiliary drive wheels; the 4WD control unit (34) has, as 2-wheel drive modes, a disconnect 2-wheel drive mode in which the dog clutch (8) and the electrically controlled coupling (16) are disengaged, and a standby 2-wheel drive in which the dog clutch (8) is engaged and the electrically controlled coupling (16) is disengaged; and a switch to the standby 2-wheel drive mode is performed when uphill movement is detected during the disconnect 2-wheel drive mode. |
