Abstract

A method of generating navigation instructions for a vehicle is provided. A destination of the vehicle is received at a route generation application. A maneuver list comprising a plurality of navigation instructions is calculated based on a current location of the vehicle and the destination. A distance threshold is determined based on the current location of the vehicle and the destination. The navigation instructions located within the distance threshold are determined and transmitted from the route generation application to the vehicle. The navigation instructions located within the distance threshold are 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:

receiving a destination of the vehicle at a route generation application;

calculating a maneuver list based on a current location of the vehicle and the destination, the maneuver list comprising a plurality of navigation instructions;

determining a distance threshold based on the current location of the vehicle and the destination;

determining navigation instructions located within the distance threshold; and

transmitting the navigation instructions located within the distance threshold from the route generation application to the vehicle.

2. The method of claim 1 further comprising:

executing the navigation instructions located within the distance threshold at the vehicle.

3. The method of claim 1 further comprising:

transmitting at least one remaining maneuver from the route generation application while the vehicle executes the navigation instructions located within the distance threshold.

4. The method of claim 3 further comprising:

executing the at least one remaining maneuver at the vehicle.

5. The method of claim 1 further comprising:

determining the distance threshold based on a speed of the vehicle.

6. The method of claim 1 further comprising:

determining the distance threshold based on road density information.

7. The method of claim 1 further comprising:

determining the maneuver list based on a speed of the vehicle.

8. The method of claim 1 further comprising:

determining the maneuver list based on road density information.

9. A navigation system comprising:

at least one route generation application

wherein the route generation application calculates a maneuver list, the list comprising a plurality of navigation instructions,

wherein the route generation application further determines a distance threshold and preliminary navigation instructions that lie within the distance threshold;

at least one service manager in communication with the route generation application and a vehicle,

wherein the vehicle is operatively adapted to execute the navigation instructions.

10. The system of claim 9 wherein the service manager transmits the

preliminary navigation instructions from the route generation application to the vehicle.

11. The system of claim 9 further comprising:

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

12. The system of claim 9 further comprising:

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

13. The system of claim 9 further comprising:

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

15. The program of claim 14, further comprising:

computer program code that executes the navigation instructions located within the distance threshold at the vehicle.

16. The program of claim 14, further comprising:

computer program code that transmits at least one remaining maneuver to the vehicle while the vehicle executes the navigation instructions located within the distance threshold.

17. The program of claim 16, further comprising:

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

18. The program of claim 14, further comprising:

computer program code that determines the distance threshold based on a speed of the vehicle.

19. The program of claim 14, further comprising:

computer program code that determines the distance threshold based on road density information.

20. The program of claim 14, further comprising:

computer program code that determines the navigation instructions based on a speed of the vehicle.

21. The program of claim 14, further comprising:

computer program code that determines the navigation instructions based on road density information.

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

computer program code that receives a destination of the vehicle;

computer program code that calculates a list of navigation instructions based on a current location of the vehicle and the destination;

computer program code that determines a distance threshold;

computer program code that determines navigation instructions located within the distance threshold; and

computer program code that transmits the navigation instructions located within the distance threshold to the vehicle.

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

means for receiving a destination of the vehicle at a route generation application;

means for calculating a maneuver list based on a current location of the vehicle and the destination, the maneuver list comprising a plurality of navigation instructions;

means for determining a distance threshold based on the current location of the vehicle and the destination;

means for determining navigation instructions located within the distance threshold; and

means for transmitting the navigation instructions located within the distance threshold from the route generation application to the vehicle.
