Abstract

A system and method for off route processing is disclosed. The system and method can be used to provide information when an off route condition occurs. The system and method can include provisions to make modifications in the way navigation information is displayed. The system and method can also provide a selectable re-route mode and selectable re-route information.

Claims

1. A system for displaying navigation information comprising:

a display including a region, the region providing a visible portion of the display and displaying a map and an indicia, the indicia representing a motor vehicle;

the system having a first condition wherein the indicia is on a route and wherein the indicia remains at a substantially fixed position with respect to the region;

the system having a second condition wherein the indicia is spaced from the route and wherein a modification is made to keep the route and the indicia within the region.

2. The system according to claim 1, wherein the modification includes a change in scale of the map.

3. The system according to claim 2, wherein the scale is increased to show a larger geographical area as the indicia moves further away from the route.

4. The system according to claim 2, wherein the scale is decreased to show a smaller geographical area as the indicia moves closer to the route.

5. The system according to claim 2, wherein the scale is returned to an original scale when the indicia returns to the route.

6. The system according to claim 1, wherein the modification includes movement of the indicia from the fixed position.

7. The system according to claim 6, wherein the indicia returns to the fixed position when the indicia returns to the route.

8. A method for providing navigation information comprising the steps of:

retrieving information related to a selected re-route mode;

sensing an off route condition; and

executing an off route process based on the selected re-route mode and in response to the off route condition.

9. The method according to claim 8, wherein re-route information is prepared if an automatic mode is the selected re-route mode.

10. The method according to claim 8, wherein a query is sent if an inquire mode is the selected re-route mode.

11. The method according to claim 10, wherein the query is configured to be sent to a user and asks the user if re-route information is needed.

12. The method according to claim 11, wherein the re-route information is prepared if the user requests the re-route information.

13. The method according to claim 11, wherein the re-route information is not prepared if the user does not request the re-route information.

14. The method according to claim 8, wherein the method waits for a request for the re-route information if a manual mode is selected as the re-route mode.

15. The method according to claim 14, wherein the re-route information is prepared if the user requests the re-route information.

16. The method according to claim 14, wherein the re-route information is not prepared if the user does not request the re-route information.

17. A method for processing an off-route condition and providing re-route directions comprising the steps of:

receiving information related to an off-route condition from an on board unit that is associated with a motor vehicle;

receiving information related to the position of the motor vehicle;

preparing re-route directions; and

sending the re-route directions to the on board unit.

18. The method according to claim 17, wherein a distance to a destination is a factor that is considered in preparing the re-route directions.

19. The method according to claim 17, wherein a distance to a route is a factor that is considered in preparing the re-route directions.

20. The method according to claim 17, wherein simplicity of the re-route directions is a factor that is considered in preparing the re-route directions.

21. The method according to claim 17, wherein a user preference is a factor that is considered in preparing the re-route directions.
