ABSTRACT:
In the case of a control device for an at least partially 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, in that the control unit determines a desired clutch torque which is to be set by means of an actuator device at the transfer clutch, the control unit receives at least one input signal for detecting an accelerator pedal position and is further developed such that, when the desired clutch torque is determined, a basic pilot control fraction is taken into account, which is defined as a function of the accelerator pedal position and is corrected as a function of additional parameters which are detected or determined by the control unit.
