Abstract

A navigation method and system are disclosed whereby users of the systems are provided with backup driving instructions. A wireless communications system allows end users'"'"' computing devices to receive dynamic route guidance from a remotely located navigation services provider. The dynamic route guidance provides each end user with maneuvering instructions at appropriate locations along a route to a desired destination. In addition to the dynamic route guidance, the navigation service provider also provides the end users with backup driving instruction data. The backup driving instruction data can be used by an end user'"'"'s computing device to provide backup driving instructions for traveling to the destination. The backup driving instruction data can be used in case wireless communications is interrupted.

Claims

1. A method of operation for an end user'"'"'s mobile computing device that provides navigation-related services to an end user, the method comprising:

on the end user'"'"'s mobile computing device,

establishing a wireless communications link with a remotely located navigation services provider;

requesting from said remotely located navigation services provider data for providing dynamic driving instructions for traveling to a destination;

obtaining the data for providing dynamic driving instructions from said remotely located navigation services provider; and

obtaining backup driving instruction data from said remotely located navigation services provider.

2. The method of claim 1 further comprising:

providing the dynamic driving instructions while the end user is traveling toward the destination.

3. The method of claim 2 wherein the step of providing the dynamic driving instructions includes providing driving instructions approaching locations at which maneuvers are to be made to travel to the destination.

4. The method of claim 1 further comprising:

if the wireless communications link is interrupted while the end user'"'"'s mobile computing device is traveling toward the destination, providing backup driving instructions using the backup driving instruction data.

5. The method of claim 1 further comprising:

providing backup driving instructions using the backup driving instruction data, wherein the backup driving instructions are text-based instructions.

6. The method of claim 1 further comprising:

from the end user'"'"'s computing platform, specifying the destination to the remotely located navigation services provider.

7. The method of claim 1 wherein the backup driving instructions data are text-based instructions.

8. The method of claim 1 further comprising:

on the end user'"'"'s computing device, determining whether the end user'"'"'s computing device is still on a route to the destination.

9. The method of claim 1 further comprising:

on the end user'"'"'s computing device, determining a position of the end user'"'"'s computing device.

10. The method of claim 1 wherein the data for providing dynamic driving instructions and the backup driving instruction data are received together on the end user'"'"'s computing device.

11. The method of claim 1 wherein the backup driving instruction data are stored in the end user'"'"'s computing device upon being received.

13. The method of claim 12 further comprising:

on the navigation services provider,

receiving from the end user'"'"'s mobile computing device a specification of the destination.

14. The method of claim 12 further comprising:

on the navigation services provider,

calculating a route to the destination.

15. The method of claim 12 wherein the backup driving instructions data are text-based instructions.

16. The method of claim 12 wherein the step of sending subsequent portions of the route guidance data for traveling to the destination occurs dynamically while the end user travels toward the destination.

17. The method of claim 12 wherein the step of sending subsequent portions of the route guidance data for traveling to the destination occurs when the end user'"'"'s mobile computing device approaches locations at which maneuvers are to be taken.

18. The method of claim 12 wherein the backup driving instructions data are sent with the initial portion of the route guidance data.

19. The method of claim 12 further comprising:

prior to sending the subsequent portions of the route guidance data, receiving data indicating a location of the end user'"'"'s mobile computing device.

20. The method of claim 12 wherein the initial portion of the route guidance data and the subsequent portions of the route guidance data include data for providing a map display.

12. A method of operation for a navigation services provider that provides navigation-related services to end users'"'"' mobile computing devices, the method comprising:

from the navigation services provider,

establishing a wireless communications link with an end user'"'"'s mobile computing device;

receiving a request from the end user'"'"'s mobile computing device for directions to travel to a destination;

sending an initial portion of route guidance data for traveling to the destination to the end user'"'"'s mobile computing device via the wireless communications link;

sending subsequent portions of route guidance data for traveling to the destination to the end user'"'"'s mobile computing device via the wireless communications link as the end user travels toward the destination; and

sending backup driving instruction data to the end user'"'"'s mobile computing device.

21. A system for providing route guidance to end users comprising:

a navigation services provider;

a wireless communications system connected to the navigation services provider;

end user computing devices each containing hardware and software for communicating with the navigation services provider over the wireless communications system; and

an application on the navigation services provider that provides dynamic route guidance to each end user computing device for traveling to a destination and backup driving instructions for traveling to the destination in case wireless communications is interrupted.

22. A navigation system capable of wirelessly communicating with a remotely located navigation services for providing route guidance to a user of the navigation system, comprising:

a route guidance application that provides route guidance to the user; and

a backup driving instruction component that stores backup driving directions for use when the route guidance cannot be provided to the user.
