摘要

Method for controlling the switching operation in an automatic gearbox comprises changing the target value for the switching force depending on the characteristic parameter such as differential revolution, duration of synchronizing or synchronization friction energy in the phase of the synchronization. Preferred Features: The target value for the switching force is reduced or increased during the synchronizing phase. Changing of the target value is successive or continuous.
