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.

Route guidance learning device

There is disclosed a navigation device designed to display emphasis display data edited by an emphasis display data editing part and normal display data edited by a normal display data editing part in a superposing manner. Thus, a clear visible map can be displayed.

Navigation device for displaying dated map data

A traffic information display device including a current position detecting unit for detecting the current position of a vehicle in which the traffic information display device is mounted, a road map storing unit for storing road map data, a map display control unit for displaying a road map image associated with an area in the vicinity of the current position of the vehicle on the screen of a display device on the basis of the current position from the current position detecting unit and road map data from the road map storing unit, a traffic information receiving unit for receiving traffic information, a traffic information display control unit for displaying traffic information from the traffic information receiving unit on the road map image displayed on the screen of the display device, and a traffic information display restricting unit for restricting a display of traffic information about a predetermined area of the on-screen road map image so as to emphasize traffic information about the remaining area of the on-screen map image including the current position of the vehicle other than the predetermined area.
