Patent ID: 7197395

Claim:
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.
