Abstract

In the case of a system for marking a region within an image of a road map detail displayed on a vehicle video screen, the regions are shown in a circular shape. The center and the dimensions of the region can be changed by a control element, which can be rotated about a longitudinal axis and can be deflected transversely to the longitudinal axis. As a result of the transverse movement of the control element, the position of the center point and, as a result of the rotating movement of the control element, the dimensions of the region within the video screen, are adjustable.

Claims

1-6. -6. (canceled)

7. A system for marking a region of a road map displayed on a vehicle display, the system comprising:

a control element rotatable about its longitudinal axis and deflectable transversely to the longitudinal axis;

wherein the marked region of the display is circular and wherein a center point and dimensions of the circular region are changeable via the control element; and

wherein the transverse movement of the control element changes the center point of the circular region and the rotational movement of the control element adjusts the dimensions of the region on the displayed road map.

8. The system according to claim 7, wherein, for the rotational movement of the control element, lock-in positions are provided, and wherein a diameter of the region is changeable in steps corresponding to the lock-in positions.

9. The system according to claim 7, wherein an enter function is provided by which the position and size of the region is fixedly defined.

10. The system according to claim 8, wherein an enter function is provided by which the position and size of the region is fixedly defined.

11. The system according to claim 9, wherein the enter function is triggerable by an axial movement of the control element.

12. The system according to claim 7, wherein, by way of an enter function, the region is included in an assigned navigation system, wherein the navigation system plans a driving route around the region.

13. The system according to claim 8, wherein, by way of an enter function, the region is included in an assigned navigation system, wherein the navigation system plans a driving route around the region.

14. The system according to claim 9, wherein, by way of an enter function, the region is included in an assigned navigation system, wherein the navigation system plans a driving route around the region.

15. The system according to claim 11, wherein, by way of an enter function, the region is included in an assigned navigation system, wherein the navigation system plans a driving route around the region.

16. The system according to claim 7, wherein via the enter function, a driving route for exiting the marked region is one of provided and selected when a current location of the vehicle is within the marked region.

17. The system according to claim 12, wherein via the enter function, a driving route for exiting the marked region is one of provided and selected when a current location of the vehicle is within the marked region.

18. A method of operating a vehicle navigation system having a display and a control element, the control element being rotatable about a longitudinal axis and movable axially along the longitudinal axis, the method comprising the acts of:

displaying a road map on the display;

selecting a region of the displayed road map using the control element, wherein the selected region is circular; and

changing a center point and dimensions of the circular region via the control element, wherein a transverse movement of the control element changes the center point and a rotational movement of the control element adjusts the dimensions of the circular region on the displayed road map.

19. The method according to claim 18, further comprising the act of generating a driving route via the navigation system which avoids the selected region.

20. The method according to claim 19, wherein when the navigation system determines the vehicle to be within the selected region, generating a driving route for exiting the selected region.
