Abstract

In one embodiment, a navigation system may include one or more processors, a display, a satellite antenna, one or more memory devices, and map data. A route distance icon can be presented on the display, automatically, when the current location is not coincident with the route and the start offset distance is less than a predetermined distance. The route distance icon can provide the on-the-route distance. A geodesic distance icon can be presented on the display, automatically, when the current location is not coincident with the route and the start offset distance is greater than the predetermined distance. The geodesic distance icon can provide a geodesic distance from the current location to the destination.

Claims

1. A navigation system comprising:

one or more processors;

a display communicatively coupled to the one or more processors;

a satellite antenna communicatively coupled to the one or more processors, wherein the satellite antenna receives a signal from one or more global positioning system satellites;

one or more memory devices communicatively coupled to the one or more processors; and

map data stored in the one or more memory devices, wherein the one or more processors execute machine readable instructions to;

transform the signal from the one or more global positioning system satellites into a current location of the navigation system;

determine a route from a start location to a destination, wherein the route covers an on-the-route distance between the start location and the destination;

present a map image on the display, wherein the map image is indicative of the map data stored in the one or more memory devices;

calculate, automatically, a start offset distance from the current location to the start location;

present a route distance icon on the display, automatically, when the current location is not coincident with the route and the start offset distance is less than a predetermined distance, wherein the route distance icon provides the on-the-route distance; and

present a geodesic distance icon on the display, automatically, when the current location is not coincident with the route and the start offset distance is greater than the predetermined distance, wherein the geodesic distance icon provides a geodesic distance from the current location to the destination.

2. The system of claim 1, wherein the one or more processors execute machine readable instructions to:

receive input indicative of the destination or the start location from input hardware communicatively coupled to the one or more processors.

3. The system of claim 1, wherein the one or more processors execute machine readable instructions to:

present the route distance icon on the display, automatically, immediately after the route is determined; and

remove the route distance icon from the display, automatically, after a period of time has elapsed.

4. The system of claim 3, wherein the period of time is less than about 30 seconds.

5. The system of claim 1, wherein the one or more processors execute machine readable instructions to:

provide turn-by-turn navigation on the display; and

deactivate the route distance icon and the geodesic distance icon, automatically, while the turn-by-turn navigation is provided.

6. The system of claim 1, wherein the one or more processors execute machine readable instructions to:

present the route distance icon on the display, automatically, when the current location is coincident with the destination.

7. The system of claim 1, wherein the one or more memory devices comprises a removable memory module.

8. The system of claim 1, wherein the display is a touch screen.

9. The system of claim 1, wherein the route distance icon provides an on-the-route travel time.

10. The system of claim 1, wherein the start offset distance is geodesic.

11. The system of claim 10, wherein the start offset distance is less than about 1 mile.

12. The system of claim 1, wherein the geodesic distance icon comprises a directional indicator that points substantially along a directional vector from the current location to the destination.

13. The system of claim 12, wherein the directional indicator points along a cardinal direction or intermediate direction.

14. A method for providing route guidance comprising:

receiving a signal from one or more global positioning system satellites with a satellite antenna, wherein the satellite antenna is communicatively coupled to one or more processors;

transforming the signal from the one or more global positioning system satellites into a current location of a navigation system;

determining a route from a start location to a destination, wherein the route covers an on-the-route distance between the start location and the destination;

presenting a map image on a display communicatively coupled to the one or more processors;

calculating, automatically with the one or more processors, a start offset distance from the current location to the start location; and

presenting a geodesic distance icon on the display, automatically with the one or more processors, when the current location is not coincident with the route and the start offset distance is greater than a predetermined distance, wherein the geodesic distance icon provides a geodesic distance from the current location to the destination and a directional indicator that points from the current location towards the destination.

15. The method of claim 14, further comprising:

presenting a route distance icon on the display, automatically with the one or more processors, when the current location is not coincident with the route and the start offset distance is less than the predetermined distance, wherein the route distance icon provides an on-the-route travel time.

16. The method of claim 15, wherein the route distance icon provides the on-the-route distance.

17. The method of claim 15, further comprising:

providing turn-by-turn navigation on the display; and

deactivating the route distance icon and the geodesic distance icon, automatically with the one or more processors, while the turn-by-turn navigation is provided.

18. The method of claim 14, further comprising:

presenting a route distance icon on the display, automatically with the one or more processors, immediately after the route is determined, wherein the route distance icon provides the on-the-route distance; and

removing the route distance icon from the display, automatically with the one or more processors, after a period of time has elapsed.

19. The method of claim 18, wherein the route distance icon provides an on-the-route travel time.
