Abstract:
A method and device for controlling and regulating a coupling (2) for a motor vehicle transmission in which an electronic control unit determines, via a regulating circuit, behavior of the coupling (2), the method comprising the steps of:using a first regulating circuit (3) for controlling and regulating the coupling (2) both in a first operational state corresponding to a starting operation and in a second operational state corresponding to driving with a variable ratio (i=var); equating a regulated quantity for the first regulating circuit to an actual value of a differential rotational speed (dnK_IST) of the coupling (2); and determining a continuously variable adjustment of the continuously variable transmission (1) by a second regulating circuit (4) with the first regulating circuit (3) and second regulating circuit (4) being interconnected via an uncoupling network (7, 8, 13, 14).
