For monitoring a sensor using differential voltage evaluation for detecting a short circuit to ground and/or to supply voltage U, a first resistor and a second resistor R, Rare assigned to the sensor, a sum voltage is determined from voltages U, Uat terminals of the sensor, the sum voltage is compared to supply voltage U, a ratio a of determined sum voltage to supply voltage Uis then calculated, and depending on the value for the ratio a, the occurrence of a shunt at the positive terminal and/or negative terminal of the sensor is detected.

Method for shunt detection in sensors

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; Z, Z, Z, Z, Z, Z, Z, Z) from current states (z(t)) to subsequent states (z(t+1)) and that the states (z; Z, Z, Z, Z, Z, Z, Z, Z) are all configurable without change of program. A method is provided for the program-controlled drive of at least one pressure actuating member.
