Abstract

In a method for displaying information with the aid of a display mounted in a motor vehicle, graphic data which actuate at least a subregion of the display are generated by a user interface device, such that in an operating state, information that is assigned to at least one operator step able to be executed by an input device are generated and in a display state, information which is not assigned to any operator steps is displayed, and it is detected when an object enters an operator control zone assigned to the input device, and when it leaves the operator control zone. The method is characterized in that the user interface device switches from the operating state to the display state when the object leaves the operator control zone and the object does not reenter the operator control zone within a defined time interval. Furthermore, a display device is adapted for executing this method.

Claims

1. A method for displaying information with the aid of a display mounted in a motor vehicle, comprising:

generating, by a user interface device, graphic data which actuate at least a subregion of the display such that in an operating state, information which is assigned to at least one operator step executable by an input device is displayed, and in a display state, information which is not assigned to any operator steps is displayed, and it is detected when an object enters an operator control zone assigned to the input device and when the object leaves the operator control zone; and

switching the user interface device from the operating state to the display state when the object leaves the operator control zone and the object does not reenter the operator control zone within a defined time interval.

2. The method according to claim 1, wherein when the object enters the operator control zone, the user interface device switches from the display state to the operating state.

3. The method according to claim 1, wherein when the switch takes place from the display state to the operating state, at least a portion of the displayed graphical objects is shown in enlarged size.

4. The method according to claim 3, wherein a length of the time interval is within a range of one second to six seconds.

5. The method according to claim 3, wherein a length of the time interval is within a range of two seconds to five seconds.

6. The method according to claim 3, wherein a length of the time interval is five seconds.

7. The method according to claim 3, further comprising:

detecting a speed of the vehicle; and

determining a length of the time interval as a function of the vehicle speed.

8. The method according to claim 1, wherein a display scale is modified in the switch from the display state to the operating state.

9. The method according to claim 8, wherein a length of the time intervals is within a range of one second to six seconds.

10. The method according to claim 8, wherein a length of the time interval is within a range of two seconds to five seconds.

11. The method according to claim 8, wherein a length of the time interval is five seconds.

12. The method according to claim 8, further comprising:

detecting a speed of the vehicle; and

determining a length of the time interval as a function of the vehicle speed.

13. The method according to claim 1, wherein a length of the time interval is within a range of one second to six seconds.

14. The method according to claim 1, wherein a length of the time interval is within a range of two seconds and five seconds.

15. The method according to claim 1, wherein a length of the time interval is five seconds.

16. The method according to claim 1, wherein the input device includes a touch-sensitive surface of the display.

17. The method of claim 1, wherein the display state only includes the display of information not assigned to any operator steps.

18. The method of claim 1, wherein the operating state further includes display of information not assigned to any operator steps.

19. A display device for a motor vehicle, comprising:

a display mounted in the motor vehicle;

an input device;

a proximity sensor adapted to detect an entry of an object in an operator control zone assigned to the input device and a departure from the operator control zone; and

a user interface device adapted to generate graphic data to actuate at least a subregion of the display such that in an operating state, information assigned to an operator step executable by the input device is displayed, and in a display state, information that is not assigned to any operator steps is displayed;

wherein the user interface device is adapted to switch from the operating state to the display state when the object leaves the operator control zone and the object does not reenter the operator control zone within a defined time interval.

20. The display device according to claim 19, wherein the user interface device includes a memory adapted to store a length of the time interval is stored.

21. The display device according to claim 20, wherein the length of the time interval stored in the memory is within a range of one second to six seconds.

22. The display device according to claim 19, wherein the input device includes a touch-sensitive surface of the display.

23. The display device of claim 19, wherein the display state only includes the display of information not assigned to any operator steps.

24. The display device of claim 19, wherein the operating state further includes display of information not assigned to any operator steps.
