Abstract
A method of the rapid filling of a hydraulically actuated multiple-disk shifting element () of a motor vehicle transmission (), in particular a disk clutch () of an all-wheel transfer transmission (). The disk shifting element () 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).
