In the case of a control device for an at least temporarily four-wheel-driven motor vehicle, having a control unit which can variably distribute the driving torque of a drive unit as a function of operating conditions to primary driving wheels, which are permanently connected with the drive unit, and to secondary driving wheels which, if required, can be connected by way of a transfer clutch with the drive unit, in that the control unit determines a desired clutch torque which is to be set by an actuator device at the transfer clutch, one operating condition is the vehicle speed. The control unit is further developed such that, when the desired clutch torque is determined, at least one defined high-speed range is taken into account and in that a speed-range-related clutch torque assigned to the high-speed range is defined as a maximally permissible limit torque.
