Abstract
A method of adapting the rapid filling time of a clutch. During adaptation, the clutch is filled by at least two successive rapid filling pulses with increasing rapid filling times. For each rapid filling pulse a reaction, resulting from the filling pulse, is monitored. If a defined reaction, for one of the rapid filling pulses, is recognized for the first time whereas for the, or for each of the previous rapid filling pulse(s) the defined reaction was not observed, then as a function of the rapid filling time of that rapid filling pulse for which the defined reaction was recognized for the first time, carrying out the adaptation of the rapid filling time and, for each rapid filling pulse used for the adaptation, gradients of the clutch pressure produced as a result of the respective rapid filling pulse are evaluated to determine the defined reaction pressure.
