The invention relates to a control device for operating a road-coupled all-wheel drive vehicle having at least one electronic control unit, having at least a first drive motor as a primary motor assigned to a primary axle and having at least a second drive motor as a secondary motor assigned to a secondary axle. According to the invention, the control unit has a gradient-limiting module for performing a torque gradient limiting function in such a manner that, in the event of a change of the target all-wheel drive factor on the basis of a defined driver's request signal, first the new target all-wheel drive factor is predetermined in a sudden manner and second, in the course of the subsequent adjustment of the all-wheel drive factor, the gradient of the driver's request signal forms the gradient limitation for the maximum admissible adjustment of the torque of the primary motor and/or secondary motor.
