Abstract: A procedure for the control and regulation of a clutch in an automated stepped transmission for a motor vehicle, in which an electronic control device by means of a first or second regulation circuit determines the behavior of the clutch during three driving conditions and that a traction interrupted shifting from a first into a second gear ratio is carried out. In accord with the invention, for the control and the regulation of the clutch during the first driving condition the first regulation circuit is employed, the size of the regulation thereof being equivalent to the actual value of the motor speed of rotation (n_MOT_IST). During the second driving condition, a second regulating circuit is employed, the size of the regulation thereof being equivalent to the actual value of a difference in speeds of rotation (dnK_IST) of the clutch and during the third driving condition, the clutch is subjected to a controlled pressure value dependent upon various value influences.

Abstract: A method and device for a coupling (2) in a motor vehicle, transmission (1) are proposed in which the coupling is controlled and regulated during three operational states via a first regulating circuit (3). The regulated quantity corresponds to the actual value of a differential rotational speed of the coupling (2). The first state corresponds to a starting operation, the second state to the operation with constant ratio and the third state exists when a gear shift under load or a change of ratio from a first to a second ratio step of an automatic transmission (1) is initiated.
