Abstract:
A method for performing gear shifting by engaging a coupling element with a gear wheel includes moving the coupling element relative to the gear wheel from a disengaged position to an engaged position, in which a particular gear is selected. A speed of the coupling element relative to a speed of the gear wheel is controlled during movement of the coupling element so that a speed difference is maintained until the coupling element reaches the engaged position.
