Abstract

Deviant position determining means determines whether or not a vehicle deviated from a set route, detects route deviation information such as a route deviated position when a vehicle deviated, and stores it as past route deviation information in route deviant position storing means. The route searching means searches a route to the destination based on information obtained by position detecting means and map information acquiring means, and past route deviation information obtained from the route deviant position storing means. The route guidance changing means determines whichever route guidance method is the best based on information obtained by the route searching means and from the route deviant position storing means, and instructs a route guidance outputting means.

Claims

1. A route guidance learning device comprising:

operation inputting means for inputting the destination;

position detecting means for detecting the current position;

map information acquiring means for acquiring map information;

route-searching means for searching a route from the current position to the destination on the basis of information input through the operation inputting means, the position detecting means, and the map information acquiring means;

route deviant position determining means for determining a deviated position from the searched route;

route deviant position storing means for storing the determined route deviated position; and

route guidance changing means for changing a route guidance on the basis of information on the route deviated position stored in the route deviant position storing means.

2. The route guidance learning device according to claim 1, wherein the route deviant position storing means for storing the information on the route deviated position by correlating with information obtained by driver inputting means.

3. The route guidance learning device according to claim 1, wherein the route deviant position storing means accumulates information on a newly determined route deviated position.

4. The route guidance learning device according to claim 1, wherein the route deviant position storing means for storing the information on the route deviated position by correlating with information input by a driver through the operation inputting means.

5. The route guidance learning device according to claim 1, wherein the route searching means for searching a route by getting around the route deviated position stored in the route deviant position storing means.

6. The route guidance learning device according to claim 1, wherein the route guidance changing means changes contents of a display of a route guidance.

7. The route guidance learning device according to claim 1, wherein the route guidance changing means changes contents of a voice output of a route guidance.

8. The route guidance learning device according to claim 1, wherein the route guidance changing means changes volume of a voice output of a route guidance.

9. The route guidance learning device according to claim 1, wherein the route guidance changing means changes the number of times of a route guidance.

10. The route guidance learning device according to claim 1, wherein the route guidance changing means changes a voice speed of a route guidance.

11. The route guidance learning device according to claim 1, wherein the route guidance changing means delays or advances timing of a route guidance.

12. The route guidance learning device according to claim 1, wherein the route guidance changing means is provided with route guidance method determining/changing means.
