Abstract
A method and a device for actuating a dog clutch () of a gearbox () of an electrically driveable vehicle () determines at least relative rotational speeds and/or rotational angle positions of a sliding sleeve () and of a coupling element () relative to each other, in order to avoid a possible tooth-to-tooth position. In the case of a predicted tooth-to-tooth position, control measures are carried out, which change the relative rotational angle position of the sliding sleeve () and of the coupling element () relative to each other and/or the duration of the movement of the sliding sleeve () in such a way that, when an engagement position is reached, delay-free form-fitting meshing of associated sets of dog teeth () is carried out.
