Abstract:
A method of the rapid filling of a hydraulically actuated multiple-disk shifting element (4) of a motor vehicle transmission (2), in particular a disk clutch (4) of an all-wheel transfer transmission (3). The disk shifting element (4) is filled using a target value (p_soll) for the filling pressure which depends on the motor speed (n_mot). In the event that the motor speed (n_mot) changes during a filling process, the target value (p_soll) for the filling pressure is adapted as a function of the new motor speed (n_mot).
