Method for adapting the rapid filling time of a clutch

A method of adapting a rapid filling time of a clutch of a drive-train, the method comprising the steps of:

• filling the clutch for adaptation by at least two successive rapid filling pulses each with increasing rapid filling times,
• for each rapid filling pulse used for the adaptation, monitoring a reaction generated as a result of the respective rapid filling pulse, and
• if a defined reaction is recognized for the first time, for one of the rapid filling pulses, whereas for the, or for each previous rapid filling pulse, 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, the adaptation of the rapid filling time is carried out and for each rapid filling pulse used for the adaptation, to determine the defined reaction, pressure gradients of the clutch pressure produced as a result of the respective rapid filling pulse are evaluated.
