Abstract

A method of navigating a vehicle includes determining a route. At least one probable off-route condition is determined based on the route. Digital map information is transmitted based on the determination of the at least one probable off-route condition from a call center to a vehicle telematics unit via a wireless connection.

Claims

1. A method of navigating a vehicle, the method comprising:

determining a route;

determining at least one probable off-route condition based on the route; and

transmitting digital map information based on the determination of the at least one probable off-route condition from a call center to a vehicle telematics unit via a wireless connection.

2. The method of claim 1, wherein the route is determined at the call center.

3. The method of claim 1, wherein determining the at least one probable off-route condition comprises applying at least one rule.

4. The method of claim 3, wherein the at least one rule is selected from a group consisting of a point-of-interest rule, a waypoint rule, an intersection number rule, an intersection density rule, a distance between intersections rule, a road classification rule, and an off-route condition history rule.

5. The method of claim 4, wherein the off-route condition history is selected from a group consisting of a personal off-road condition history and a collective off-road condition history.

6. The method of claim 1 further comprising determining an off-route condition database.

7. The method of claim 1, wherein determining the at least one probable off-route condition comprises configuring at least one rule.

8. The method of claim 7, wherein configuring the at least one rule comprises at least one of weighting at least one rule, ordering at least one rule, including at least one rule, and excluding at least one rule.

9. The method of claim 7, wherein configuring the at least one rule is selected from a group consisting of an application configuration and a user level configuration.

10. The method of claim 1 further comprising determining a route correction based on the transmitted digital map information.

11. A computer usable medium including a program for navigating a vehicle, the computer usable medium comprising:

computer readable program code for determining a route;

computer readable program code for determining at least one probable off-route condition based on the route; and

computer readable program code for transmitting digital map information based on the determination of the at least one probable off-route condition from a call center to a vehicle telematics unit via a wireless connection.

12. The computer usable medium of claim 11, wherein the route is determined at the call center.

13. The computer usable medium of claim 11, wherein determining the at least one probable off-route condition comprises applying at least one rule.

14. The computer usable medium of claim 13, wherein the at least one rule is selected from a group consisting of a point-of-interest rule, a waypoint rule, an intersection number rule, an intersection density rule, a distance between intersections rule, a road classification rule, and an off-route condition history rule.

15. The computer usable medium of claim 14, wherein the off-route condition history is selected from a group consisting of a personal off-road condition history and a collective off-road condition history.

16. The computer usable medium of claim 11 further comprising computer readable program code for determining an off-route condition history.

17. The computer usable medium of claim 11, wherein determining the at least one probable off-route condition comprises configuring at least one rule.

18. The computer usable medium of claim 11 further comprising computer readable program code for determining a route correction based on the transmitted digital map information.

19. A system for navigating a vehicle, the system comprising:

means for determining a route;

means for determining at least one probable off-route condition based on the route; and

means for transmitting digital map information based on the determination of the at least one probable off-route condition from a call center to a vehicle telematics unit via a wireless connection.

20. The system of claim 19 further comprising means for determining an off-route condition history.
