Abstract:
A method for controlling and regulating a coupling (2) of a motor vehicle transmission in which an electronic control unit determines, via a first regulating circuit (3), a behavior of said coupling (2) during first, second and third operational states, wherein a regulated quantity is equivalent to a differential rotational speed (dnK_IST) of the coupling (2) and the first operational state corresponding to a starting operation, the second operational state corresponding to driving with a constant ratio (i=const) and the third operational state occurring upon initiation of a gear shift under load from a first step ratio e(i1) to a second step ratio (i2) of an automatic transmission (1), the method comprises the steps of:determining a gear shift under load from the first step ratio (i1) to the second step ratio (i2) step of the automatic transmission (1) by a second regulating circuit (4), and interconnecting the first regulating circuit (3) with the second regulating circuit(4) by an uncoupling network (7, 8, 13, 14).
