Hydraulic or pneumatic control of an automated shift transmission

A method for actuating control elements in one of a hydraulic or pneumatic control device (1) of an automated shift transmission, which comprises actuating devices with actuating cylinders (15, 16) having pressure spaces (19a, 19b;

• 20a, 20b), a respective control valve (22a, 22b;
• 32a, 32b) connecting the pressure spaces (19a, 19b;
• 20a, 20b) to an intermediate pressure line (26) which is one of selectively, by main shut-off valves (45a, 45b), connected to or cut off from a main pressure line (8), the method comprising the steps of:
• determining a pressure medium demand of the actuating devices (13, 14) and the respective control valves (22a, 22b;
• 32a, 32b) with a plurality of main shut-off valves (45a, 45b) which are arranged in parallel between the main pressure line (8) and the intermediate pressure line (26);
• actuating the main shut-off valves (45a, 45b) depending on the determined pressure medium demand;
• and
• estimating the pressure medium demand before a shift operation and thereafter for a duration of the shift process, and if the pressure medium demand is high, then a first a plurality of main shut-off valves (45a, 45b) are opened, and if the pressure medium demand is low, then only one of the plurality of main shut-off valves (45a or 45b) is opened.
