Abstract

A deviant position detector that 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 a route deviant position memory. A route searching device searches a route to a destination based on information obtained by a position detector and a map information acquiring device, and further searches past route deviation information obtained from the route deviant position memory. A route guidance changing device determines whichever route guidance method is the best based on information obtained by the route searching device and from the route deviant position memory, and instructs a route guidance outputting device to output the best route guidance method.

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 guidance outputting means for outputting route guidance regarding the searched route provided by the route searching means;

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

route deviant position storing means for storing the newly determined route deviated position and previously determined route deviated positions, where the previously determined route deviated positions were determined when the searched route was last traveled; and

route guidance changing means for changing the route guidance, prior to outputting the route guidance for the searched route, on the basis of information on the previously determined route deviated positions stored in the route deviant position storing means, such that the outputted route guidance avoids the previously determined route deviated positions.

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 deviated position information on the newly determined route deviated position and the previously determined route deviated positions, for changing the route guidance when the searched route is requested yet again, such that each time the searched route is subsequently requested, the route guidance is updated based on all accumulated deviated position information.

4. The route guidance learning device according to claim 1, wherein the route deviant position storing means stores deviated position information on the newly determined route deviated position and the previously determined route deviated positions 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 guidance changing means changes contents of a display of the route guidance.

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

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

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

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

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

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

12. The route guidance learning device according to claim 1, wherein the route deviant position storing means accumulates deviated position information on the newly determined route deviated position and the previously determined route deviated positions for each one of a plurality of drivers, such that the route guidance for the searched route will vary depending on which one of the plurality of drivers has requested the searched route.
