摘要
A process for controlling and regulating a clutch in a stepped load switchable automatic transmission for a motor vehicle where an electronic control device determines the behavior of the clutch during three operating conditions by way of a first or a second control circuit, and that a shift from a first into a second gear ratio stage takes place. In accordance with the invention, the first control circuit is used for controlling and regulating the clutch during the first operating condition, whose controlled variable is equivalent to the actual value of the engine speed (n_MOT_IST). During the second driving condition, a second control circuit is used, whose controlled variable is equivalent to the actual value of a differential rotational speed (dnK_IST) of the clutch, and during the third operating condition, the clutch is impinged with a controlled pressure value dependent upon various influence magnitudes.
