Abstract:
A device for supplying pressure from an energy storage device to a piston gear shifting actuator by way of a valve device is provided. A pressure regulating and/or control device is used to regulate and/or control the pressure applied to the piston actuator. The pressure regulating and/or control device regulates and/or controls the pressure according to at least one following quantity: temperature, in particular a transmission operating temperature, the load state of the motor vehicle provided with the transmission, and the slope of a surface along which the motor vehicle provided with the transmission runs.
