ABSTRACT:
A pressure control for the program-controlled drive of at least one pressure actuating member influences the hydraulic constellation in a transmission via the pressure (p). The program-controlled drive takes place via changes of states (z; Z0, Z1, Z2, Z3, Z4, Z5, Z6, Z7) from current states (z(t)) to subsequent states (z(t+1)) and that the states (z; Z0, Z1, Z2, Z3, Z4, Z5, Z6, Z7) are all configurable without change of program. A method is provided for the program-controlled drive of at least one pressure actuating member.
