Abstract

The present invention relates to a control element, in particular, a switching device for the manual actuation of functions in a motor vehicle, having a handle. The handle is mounted on a carrier such that the handle is adjustable in two different directions from a neutral position into adjustment positions. The control element furthermore has a means for the detection of the adjustment positions, wherein the means for the detection of the adjustment positions has a code carrier, which encodes the adjustment positions, and comprises a sensor which senses the coding, in such a way that all adjustment positions can be detected by way of the one code carrier.

First claim

1 . A control element, in particular switching device for the manual actuation of functions in a motor vehicle, having a handle, wherein the handle is mounted on a carrier such that the handle is adjustable in two different directions from a neutral position into at least in each case one adjustment position associated with the respective direction, and having a means for the detection of the adjustment positions, wherein the means for the detection of the adjustment positions has a code carrier which has a coding for the adjustment positions, and comprises a sensor which senses the coding, in such a way that all adjustment positions can be detected by way of the one code carrier.

2 . The control element as claimed in claim 1 , wherein the handle is a pivotable selector lever, in that, preferably, the handle is adjustable about a first and a second pivot axis in a first and a second pivoting direction, in that, more preferably, the two pivoting directions are approximately perpendicular to one another, and in that, even more preferably, the carrier for the handle is formed in the manner of a Cardan joint and/or a universal joint.

3 . The control element as claimed in claim 1 , wherein, during adjustment of the handle, the code carrier and the sensor are movable relative to one another, and in that, preferably, the code carrier and/or the sensor are/is movable by way of the handle correspondingly to the adjustment of the handle.

4 . The control element as claimed in claim 1 , wherein the code carrier interacts with the handle such that the code carrier is, owing to the pivoting movement of the handle, linearly movable in two, in particular mutually perpendicular, directions, and in that, preferably, the interaction of the handle with the code carrier is effected by way of a pin that engages into an elongated hole.

5 . The control element as claimed in claim 1 , wherein a pin is arranged on the handle, in particular on a lever arm of the handle, wherein the pin engages into an elongated hole, which runs in one direction, of the code carrier, and in that, preferably, at least one pin is arranged on the carrier, in particular on an elongation on the carrier, wherein the pin engages into an elongated hole, which runs in the further direction, of the code carrier.

6 . The control element as claimed in claim 1 , wherein the code carrier comprises a magnetic code plate, and the sensor is composed of a magnetic sensor, in particular a Hall sensor, a magnetoresistive sensor, an inductive sensor or the like, wherein, preferably, the coding for the adjustment positions is composed of a magnetization, associated with the respective adjustment position, of the code plate.

7 . The control element as claimed in claim 1 , wherein the code carrier comprises a printed circuit board, and in that, preferably, the magnetic code plate is arranged on the printed circuit board.

8 . The control element as claimed in claim 1 , wherein the code plate is fastened to the printed circuit board by way of spacer pieces in the form of separators, and in that, preferably, the spacer pieces are in the form of, in particular coated, metal spacers, in such a way that the code plate is fastened magnetically to the printed circuit board.

9 . The control element as claimed in claim 1 , wherein the spacer pieces are applied to the printed circuit board in an SMD process.

10 . A control element, in particular switching device for the manual actuation of functions in a motor vehicle, having a handle, wherein the handle is mounted on a carrier such that the handle is adjustable in at least one direction from a neutral position into an adjustment position, and wherein the adjustment movement is in the form of a detent movement and/or the adjustment position is in the form of a detent position, in such a way that a detent force acts on the handle during the adjustment movement and/or in the adjustment position, in particular as claimed in claim 1 , wherein the detent force can be generated by way of a spring-loaded thrust piece.

11 . The control element as claimed in claim 10 , wherein the handle is adjustable from a neutral position in two different directions into at least in each case one adjustment position associated with the respective direction, and in that, preferably, a means for the detection of the adjustment positions is provided.

12 . The control element as claimed in claim 10 , wherein the handle is a pivotable selector lever, in that, preferably, the handle is adjustable about a first and a second pivot axis in a first and a second pivoting direction, in that, more preferably, the two pivoting directions are approximately perpendicular to one another, and in that, even more preferably, the carrier for the handle is formed in the manner of a Cardan joint and/or a universal joint.

13 . The control element as claimed in claim 10 , wherein the spring-loaded thrust piece can be placed in interaction with a slotted guide in particular for the purposes of generating a haptic action for the adjustment of the handle, and in that, preferably, the spring-loaded thrust piece is pushed into the slotted guide for interaction purposes by way of a movable adapter.

14 . The control element as claimed in claim 10 , wherein the handle can be blocked with regard to the adjustment and can be released for the adjustment, in that, preferably, the blocking and/or the release of the handle are/is realized by way of a geometry integrally formed on the adapter, and in that, more preferably, an actuable blocking means is capable of being operatively connected to the geometry.

15 . The control element as claimed in claim 10 , wherein the adapter can be moved, for the purposes of acting on the thrust piece, by way of an actuator.

16 . The control element as claimed in claim 10 , wherein the actuator is an electric motor, an electromagnet or the like.

17 . A control element, in particular switching device for the manual actuation of functions in a motor vehicle, having a handle, wherein the handle is mounted on a carrier such that the handle is adjustable manually by a user, wherein, in particular, the handle can be blocked with regard to operation and released for operation by the user, in particular as claimed in claim 1 , wherein a sensor for interaction with the handle is provided, in such a way that, as a result of the handle being approached and/or touched, in particular gripped, by the user, in particular by a hand of the user, the operating demand of the user can be identified and the handle can be released for operation, and/or some other functionality in the motor vehicle can be triggered.

18 . The control element as claimed in claim 17 , wherein the handle is adjustable from a neutral position in two different directions into at least in each case one adjustment position associated with the respective direction, and in that, preferably, a means for the detection of the adjustment positions is provided.

19 . The control element as claimed in claim 17 , wherein the handle is a pivotable selector lever, in that, preferably, the handle is adjustable about a first and a second pivot axis in a first and a second pivoting direction, in that, more preferably, the two pivoting directions are approximately perpendicular to one another, and in that, even more preferably, the carrier for the handle is formed in the manner of a Cardan joint and/or a universal joint.
