Abstract
In a four wheel drive vehicle having a central power distribution device for transmitting engine power to a combination of left and right front wheels and a combination of left and right rear wheels with an action of differentiating rotation between the combination of the left and right front wheels and the combination of the left and right rear wheels, a skidding control device locks up the rotation differentiating action of the central power distribution device when at least either a difference between the rotation of the left front wheel and the rotation of the right front wheel or a difference between the mean rotation of the left front wheel and the right front wheel and the rotation of the combination of the left and right rear wheels exceeds a limit value predetermined therefor.
