Abstract

In an operating device for menu-controlled functions of a motor vehicle that can be shown symbolically on a screen and selected by an actuator, the actuator is movable between mechanical stops into a position that corresponds to the position of the symbol of the selectable function on the surface of the screen and which provides haptic feedback to the actuator when the selectable function is changed by moving the actuator.

Claims

1. An operating device for menu-controlled functions of a vehicle which are symbolically displayed on a screen, comprising:

an actuator which selects said menu-controlled functions, said actuator being movable at least linearly over an operating surface which spatially corresponds to a surface of the screen into a position corresponding to a symbol position of a selected menu-controlled function on the screen surface wherein each of said menu-controlled functions on the screen corresponds to a unique position within the operating surface;

mechanical stops arranged as part of the operating device to limit said movement of the actuator over the operating surface; and

wherein the actuator provides haptic feedback when the selected menu-controlled function is changed via movement of the actuator.

2. The operating device according to claim 1, wherein an intensity of the haptic feedback increases as said actuator moves toward the mechanical stops.

3. The operating device according to claim 1, wherein said actuator is movable in a vertical direction in a plane of the operating surface.

4. The operating device according to claim 2, wherein said actuator is movable in a vertical direction in a plane of the operating surface.

5. The operating device according to claim 1, wherein said actuator is movable in a horizontal direction in a plane of the operating surface.

6. The operating device according to claim 2, wherein said actuator is movable in a horizontal direction in a plane of the operating surface.

7. The operating device according to claim 3, wherein said actuator is movable in a horizontal direction in a plane of the operating surface.

8. The operating device according to claim 5, further comprising a mechanical transmission coupled to said actuator;

and

an electrical scanning device coupled to said mechanical transmission.

9. The operating device according to claim 1, wherein said actuator is rotatable about an axis.

10. The operating device according to claim 2, wherein said actuator is rotatable about an axis.

11. The operating device according to claim 3, wherein said actuator is rotatable about an axis.

12. The operating device according to claim 1, wherein said actuator is pivotable in a horizontal direction in a plane of the operating surface.

13. The operating device according to claim 2, wherein said actuator is pivotable in a horizontal direction in a plane of the operating surface.

14. The operating device according to claim 3, wherein said actuator is pivotable in a horizontal direction in a plane of the operating surface.

15. The operating device according to claim 1, further comprising a frame in which said actuator is movable between the mechanical stops.

16. The operating device according to claim 1, further comprising a trigger switch associated with said actuator, said trigger switch triggering the selected menu-controlled function.

17. The operating device according to claim 16, wherein said trigger switch is movable via said actuator.

18. The operating device according to claim 16, wherein said trigger switch is integrated with the actuator.

19. The operating device according to claim 17, wherein said trigger switch is integrated with the actuator.

20. The operating device according to claim 2, wherein said actuator is rotatable around an axis and has a fluted edge;

and

further comprising a matching part cooperating with said fluted edge of said actuator and being displaceable perpendicularly relative to the axis of rotation of the actuator.

21. The operating device according to claim 20, wherein said matching part is rotatably mounted.

22. The operating device according to claim 20, wherein said matching part is spring-mounted.

23. The operating device according to claim 21, wherein said matching part is spring-mounted.

24. The operating device according to claim 20, wherein a position of said matching part is adjustable relative to said actuator.

25. The operating device according to claim 24, wherein said matching part is adjustable in an end position in which rotary motion of said actuator is blocked.

26. The operating device according to claim 20, further comprising an electromagnet arranged to move said matching part.

27. The operating device according to claim 9, wherein said axis extends in parallel to a plane of the operating surface.

28. The operating device according to claim 10, wherein said axis extends in parallel to a plane of the operating surface.

29. The operating device according to claim 11, wherein said axis extends in parallel to a plane of the operating surface.

30. The operating device according to claim 20, wherein said axis extends in parallel to a plane of the operating surface.

31. An operating device for menu-controlled functions of a vehicle which are symbolically displayed on a screen, comprising:

an actuator which selects said menu-controlled functions, said actuator being movable at least linearly over an operating surface which spatially corresponds to a surface of the screen into a position corresponding to a symbol position of a selected menu-controlled function on the screen surface;

mechanical stops arranged as part of the operating device to limit said movement of the actuator over the operating surface;

wherein the actuator provides haptic feedback when the selected menu-controlled function is changed via movement of the actuator; and

wherein the haptic feedback provides an increasing force opposite a direction of movement when the actuator is moved from one position corresponding to one function field symbolically displayed on the screen toward an imaginary boundary of another position corresponding to an adjoining function field symbolically displayed on the screen.

32. The operating device according to claim 31, wherein when the actuator crosses the imaginary boundary, the haptic feedback provides a force assisting the direction of movement in order to move the actuator away from the imaginary boundary into the adjoining function field.
