ABSTRACT:
To be able to verify the function of the actuator system of an automatic clutch or of an automatic transmission of a motor vehicle as a function of the current conditions, including while the motor vehicle is in motion is necessary, the invention teaches that a test circuit actuates the actuator system, starting from a first specified operating position of the clutch or of the transmission to a second specified operating position of the clutch or of the transmission, into an actuator test position in which the clutch or the transmission is still essentially in its first operating position. The test circuit, in the actuator test position, tests the functional capability as a function of data stored in a data memory, which stored data are compared to data measured in the actuator test position of a changing operating parameter.
