ABSTRACT:
In the case of a control device for an at least part-time four-wheel-driven motor vehicle, having a control unit which can variably distribute the driving torque of a drive unit 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, wherein the control unit determines a desired clutch torque which is to be set by an actuator device at the transfer clutch, the control unit consists of a main control unit and an additional control unit, the main control unit computing the desired clutch torque as a function of detected and/or determined parameters, which clutch torque is transmitted to the additional control unit, and the additional control unit converting the desired clutch torque to a corresponding electric control signal for the actuator device.
