Shifting device for a manual transmission
View Patent ↗A shifting device is provided for the gear selection in a manual transmission that includes, but is not limited to a shift/selector lever that can be moved in a shifting degree of freedom and a selection degree of freedom, a measuring sensor for measuring a current position (s, w) of the shift/selector lever in the two degrees of freedom, a two-dimensionally controllable actuator device and a control circuit for the controlling of the actuator device in a position (S, W) which is associated with the sensed position (s, w) of the shift/selector lever, which depicts the movement region of the shift/selector lever on a region of possible positions of the actuator device. The movement region of the shift/selector lever included, but is not limited to a two-dimensional prohibited part region, in which the shift/selector lever is simultaneously moveable in both degrees of freedom. The control circuit depicts this prohibited part region on positions on an edge of the region of the possible positions of the actuator device.
1. A shifting device for a gear selection in a manual transmission, comprising:
a shift/selector lever moveable in a shifting degree of freedom and a selection degree of freedom;
a measuring sensor adapted to sense a current position of the shift/selector lever in two degrees of freedom;
a two-dimensionally controllable actuator device; and
a control circuit adapted to control the two-dimensionally controllable actuator device in a position associated with a sensed position of the shift/selector lever, which depicts a movement region of the shift/selector lever on a region of possible positions of the two-dimensionally controllable actuator device,
wherein the movement region of the shift/selector lever comprises a two dimensional prohibited part region in which the shift/selector lever can be simultaneously moved in both degrees of freedom, and
wherein the control circuit depicts a prohibited part region on positions on an edge of the region of the possible positions of the two-dimensionally controllable actuator device.
2. The shifting device according to claim 1 , wherein the control circuit uniquely depicts each point of a permitted part region of the movement region on a position in the region of the possible positions of the two-dimensionally controllable actuator device.
3. The shifting device according to claim 2 , wherein in at least one part of a permitted region the shift/selector lever can be simultaneously moved in both degrees of freedom.
4. The shifting device according to claim 2 , wherein a permitted region comprises a strip extending in a direction of a selection degree of freedom and strips extending in the direction of the shifting degree of freedom.
5. The shifting device according to claim 4 , wherein the prohibited region borders on a crossing of the strips.
6. The shifting device according to claim 4 , wherein two prohibited regions border on a crossing of the strips located diametrically opposite each other.
7. The shifting device according to claim 1 , wherein the control circuit depicts each point of the prohibited region on a same position of the two-dimensionally controllable actuator device, as the point of an allowed region that is next adjacent to every point.
8. The shifting device according to claim 1 , wherein the control circuit depicts each point of the prohibited region on the same position of the two-dimensionally controllable actuator device as a point of a permitted region which with the point of the prohibited region has a coordinate value in common.
9. The shifting device according to claim 8 , wherein the point of the permitted region on an image position of which the control circuit depicts a point in the prohibited region is an edge point of that strip from which the shift/selector lever is engaged in the prohibited region.
10. The shifting device according to claim 9 , wherein the control circuit upon a movement of the shift/selector lever in the prohibited region tracks a common coordinate value slower than in the permitted region.
