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, 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 is further configured such that, when the
desired clutch torque is determined, at least one degree of stress to the
transfer clutch and/or at least one degree of stress to the actuator
device are taken into account. In this case, the taking into account of a
short-duration degree of stress to the transfer clutch is particularly
important with a view to a closing which is as fast as possible for
preventing a slip.
