Abstract

A method of generating navigation instructions for a vehicle is provided. A destination is requested at the vehicle and forwarded to a route generation application. At least one preliminary maneuver is calculated based on a current location of the vehicle and the destination. The preliminary maneuver is transmitted from the route generation application to the vehicle and is executed at the vehicle. Systems and programs for using the method are also provided.

Claims

1. A method of generating navigation instructions for a vehicle, comprising:

requesting a destination at the vehicle;

forwarding the destination to a route generation application;

calculating at least one preliminary maneuver based on a current location of the vehicle and the destination;

transmitting the at least one preliminary maneuver from the route generation application to the vehicle; and

executing the at least one preliminary maneuver at the vehicle.

2. The method of claim 1 further comprising:

calculating at least one remaining maneuver while the vehicle executes the at least preliminary one maneuver.

3. The method of claim 2 further comprising:

transmitting the at least one remaining maneuver to the vehicle.

4. The method of claim 2 further comprising:

executing the at least one remaining maneuver at the vehicle.

5. The method of claim 1, wherein the at least one preliminary maneuver is three maneuvers.

6. The method of claim 2, further comprising:

calculating all remaining maneuvers while the vehicle executes the at least one preliminary maneuver.

7. The method of claim 6, further comprising:

transmitting all remaining maneuvers to the vehicle.

8. A navigation system comprising:

at least one route generation application wherein the route generation application calculates at least one preliminary maneuver before calculating at least one remaining maneuver;

at least one service manager for transmitting the at least one preliminary maneuver to a vehicle,

the vehicle operatively adapted to execute the at least one preliminary maneuver.

9. The system of claim 8 further comprising:

at least one database in communication with the route generation application, the database comprising location coordinates.

10. The system of claim 8 further comprising:

at least one navigation interface in communication with the vehicle operatively adapted to receive the at least one preliminary maneuver.

11. The system of claim 8 further comprising:

at least one communication interface in communication with the vehicle, the communication interface operatively adapted to transmit location information from the vehicle.

13. The program of claim 12 further comprising:

computer program code that receives the at least one preliminary maneuver at the vehicle.

14. The program of claim 12 further comprising:

computer program code that calculates at least one remaining maneuver while the vehicle executes the at least one preliminary maneuver.

15. The program of claim 14 further comprising:

computer program code that transmits the at least one remaining maneuver to the vehicle.

16. The program of claim 14 further comprising:

computer program code that executes the at least one remaining maneuver at the vehicle.

17. The program of claim 14 further comprising:

computer program code that receives the at least one remaining maneuver at the vehicle.

18. The program of claim 12 further comprising:

computer program code that calculates all remaining maneuvers while the vehicle executes the at least one preliminary maneuver.

19. The program of claim 18, further comprising:

computer program code that transmits all remaining maneuvers to the vehicle.

20. The program of claim 18 further comprising:

computer program code that executes all remaining maneuvers at the vehicle.

12. A computer usable medium including a program for generating navigation instructions for a vehicle, comprising:

computer program code that requests a destination from the vehicle;

computer program code that forwards the destination to a route generation application;

computer program code that calculates at least one preliminary maneuver based on a current location of the vehicle to the destination;

computer program code that transmits the at least one preliminary maneuver from the route generation application to the vehicle; and

computer program code that executes the at least one preliminary maneuver at the vehicle.

21. A system for generating navigation instructions for a vehicle, comprising:

means for requesting a destination at the vehicle;

means for forwarding the destination to a route generation application;

means for calculating at least one preliminary maneuver based on a current location of the vehicle and the destination;

means for transmitting the at least one preliminary maneuver from the route generation application to the vehicle; and

means for executing the at least one preliminary maneuver at the vehicle.
