Abstract
A control system of a four-wheel drive vehicle and a gradient value setting device of the vehicle is provided so as to reliably control a wheel skid despite the vehicle facing an intersecting direction intersecting a maximum tilt line direction. The vehicle includes an engine, front and rear wheels, an electronic control 4WD coupling, and a control unit. The distribution amount of the driving force to the rear wheels is set by the electronic control 4WD coupling. The control unit determines whether or not the vehicle faces the intersecting direction on the inclined road, and if so, sets the driving force distribution amount so that the difference between the driving force distribution amount to the front wheels and to the rear wheels is smaller as compared with on a flat road, and commands the electronic control 4WD coupling to distribute the driving force by the distribution amount.
