A method is provided for controlling a hydraulic control device which can actuate a torque device and includes a first actuating element configured to be acted upon by a first fluid pressure in a first fluid line and configured to actuate the torque device; a system pressure line hydraulically connected to the first fluid line and having a system pressure; a first valve element located between the first fluid line and the system pressure line and configured to the first fluid pressure via the system pressure; and a supply element configured to provide the system pressure and being hydraulically connected to the system pressure line. The method includes setting first fluid pressure based on a predetermined target torque value, and setting the system pressure above the first fluid pressure by a pressure difference based on a pressure control value.
