Abstract:
1. 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 ( 19 a , 19 b ; 20 a , 20 b ), a respective control valve ( 22 a , 22 b ; 32 a , 32 b ) connecting the pressure spaces ( 19 a , 19 b ; 20 a , 20 b ) to an intermediate pressure line ( 26 ) which is one of selectively, by main shut-off valves ( 45 a , 45 b ), 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 ( actuating the main shut-off valves ( 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 (
