Abstract: A method for operating a continuously variable conical pulley transmission having two conical pulley sets that are operatively coupled by a endless torque-transmitting means, so that the transmission ratio between the conical pulley sets is continuously variable. A hydraulic medium is supplied to the continuously variable conical pulley transmission in a stop phase of a start/stop operation by means of a pump unit that includes a pump that is driven by an electric motor. The electric motor is controlled as a function of the temperature of the hydraulic medium.

Abstract: A hydraulic arrangement by which a plurality of shift rails of a transmission are actuated, including one double acting cylinder per shift rail by which the respective shift rail can be moved back and forth. A first hydraulic valve is connected upstream of the plurality of shift rails and has a first output and a second output, by which a first shift pressure and a second shift pressure for actuating the shift rails can be provided. A second hydraulic valve is connected between the first hydraulic valve and two of the shift rails, and by which it is selectively possible for the first output of the first hydraulic valve to be associated with one of the double acting cylinders of the two shift rails, and the second output of the first hydraulic valve to be associated with the other double acting cylinder of the two shift rails.
