Abstract
A method of operating a motor vehicle. A request for coupling a power take-off is detected. It is checked () whether relevant boundary conditions for coupling the power take-off are fulfilled. If the boundary conditions are fulfilled, a system pressure for actuating the power take-off clutch is built up (). It is checked () whether sufficient system pressure to actuate the power take-off clutch has been built up. When sufficient system pressure has sufficiently been built up, a confirmation signal is produced (). In reaction to the confirmation signal, a driving transmission control unit is modified () in order to actuate the at least one shifting element of the driving transmission with a higher actuation pressure than with an unmodified driving transmission control unit.
