  • the actual switching operation is performed electro-hydraulically or by electric motor, while the respective switching request of the driver is detected electrically or electronically.
  • the driver are in such an automated transmission, the electric switching device with a shift lever and possibly additional, arranged approximately on the steering wheel rocker switches for upshifting and downshifting available.
  • the shift lever of such a switching device is designed monostable, that is he has, similar to a joystick only a stable rest position, in which the lever from several unstable positions repeatedly falls back.
  • each exclude certain switching states of the next selection it is desirable or even necessary, depending on the currently selected switching state, each exclude certain switching states of the next selection. It is advantageous, for example, to display a linear chain of possible switching states when the choices in a switching direction are exhausted. Since in general not only the detection but also the processing of the respective switching states proceeds by electrical or electronic means, the exclusion of certain switching possibilities can and will generally be effected by the underlying switching logic. However, it is advantageous for ergonomic reasons, if the operator of the switching device also receives an immediate haptic feedback on currently not selectable switching functions. Such feedback receives the driver of a motor vehicle, in particular via locks or stops, which interact with the shift lever.
  • EP 1 464 875 A2 a switching device is known, which has an actuating device which can override a switching stop, so that the switching lever can be pivoted beyond the switching position defined by this switching stop.
  • EP 1 464 875 A2 discloses a relatively complex built-up rocker arm arrangement, which is actuated by a plurality of different actuators.
  • the electrical switching device has the advantage over this prior art device, by the use of very simple structure actuators that are able to take only two different positions to limit the actuation of a shift lever as desired, the mechanical and electrical means used simple, robust and are inexpensive.
  • This is inventively achieved in that a plurality of stop edges having stop contour firmly connected to the shift lever and is movable together with this, and that the actuators each adjust a at least one lock for the stop contour forming slide between two positions perpendicular to the direction of movement of the stop contour by alternately adjusting at least one slide a lock engaged and disengaged from the Stop contour is set, and by adjusting at least one other slide alternately two differently positioned locks are placed in engagement with the stop contour.

In this way it is possible to realize six different stop positions by only four slides 1, 2, 3, 4.

Abstract

L'invention concerne un dispositif de changement de vitesses électrique pour véhicule automobile, comprenant un levier de changement de vitesses (6) disposé de manière à pouvoir tourner autour d'un pivot (5) et pouvant être amené par manipulation dans plusieurs positions de de changement de vitesses, et comprenant des actionneurs électriques qui peuvent déplacer des butées de commande pour le levier de changement de vitesses, ce qui permet d'appliquer différents niveaux de limitation du déplacement du levier de changement de vitesses. L'objet de l'invention est caractérisé en ce qu'un contour de butée (11) qui présente plusieurs bords de butée (IIa, IIb) est relié à demeure avec le levier de changement de vitesses et peut être déplacé conjointement avec celui-ci, et en ce que les actionneurs (7-10) déplacent respectivement un coulisseau formant au moins un verrou (1-4) pour le contour de butée dans chaque cas entre deux positions, perpendiculairement au sens de déplacement du profil de butée. Selon l'invention, le déplacement d'au moins un coulisseau (1, 2, 4) amène un verrou alternativement en prise et hors de prise avec le contour de butée et le déplacement d'au moins un autre coulisseau (3) amène alternativement deux verrous (3a, 3b) positionnés différemment en prise avec le contour de butée.
