PROBLEM TO BE SOLVED: To provide a four-wheel drive vehicle in which a change-over switch can select the change-over to either the fuel consumption-oriented two-wheel drive mode or the traveling-oriented four-wheel drive mode, and a control device of the four-wheel drive vehicle which can prevent occurrence of any torque-steer phenomenon without providing any electronic controlled power steering device in a condition in which the change-over switch is selected to the fuel consumption two-wheel drive side. SOLUTION: In a traveling condition in which a drive mode change-over switch 9 is selected to the two-wheel drive mode oriented to the fuel consumption, if any torque steer occurring condition (when the vehicle speed Vcar is≥10 km/h, and the accelerator opening is≥60%) is detected, the drive mode is temporarily switched to the four-wheel drive mode, and the driving force is distributed to the rear wheel side by a front and rear driving force distribution device 7.
