Abstract

A display device, having a traffic lane recording, in which lane markings of the recorded traffic lane are shown in the display in such a way that the quality of the traffic lane recording can be discerned.

Claims

1-11. -11. (canceled)

12. A display device comprising:

a recording device for recording a traffic lane;

a display; and

an evaluation unit for computing a lane marking to form such an illustration of the lane marking in the display that a type of the illustration of the lane marking indicates a quality of the recording of the lane.

13. The display device according to claim 12, further comprising a processor for computing the lane marking in such a way that the lane marking is illustrated in the display in such a way that it is shown to a driver in place of an actual lane marking.

14. The display device according to claim 12, wherein the display is a head-up display and the lane marking is projected in the head-up display in such a way that it appears to a driver to be in a driving space ahead of a vehicle.

15. The display device according to claim 12, further comprising a camera for recording a driving space ahead of a vehicle, a camera image being shown in the display and the lane marking being entered on the camera image.

16. The display device according to claim 12, further comprising a warning unit for an optical and/or acoustical warning in the case of a falling off in a quality of the recording of the traffic lane below a specified measure.

17. The display device according to claim 12, wherein the lane marking is shown in the display using a color and/or stroke type corresponding to a quality of a traffic lane detection.

18. A method for displaying a lane marking on a display in a vehicle, comprising:

ascertaining a traffic lane ahead of the vehicle; and

showing a lane marking corresponding to the traffic lane in the display in such a way that a quality of a traffic lane detection is characterized using a type of illustration of the lane marking.

19. The method according to claim 18, further comprising entering a lane boundary marking on the display as a lane marking.

20. The method according to claim 18, further comprising entering a middle of a traffic lane on the display as a lane marking.

21. The method according to claim 18, further comprising varying a color and/or a stroke illustration of a lane marking to characterize the quality of the traffic lane detection.

22. The method according to claim 18, further comprising, in case of a deterioration of the traffic lane detection, emitting an additional optical and/or acoustical warning.
