Abstract
An identification unit identifies a departure point of a travel locus of a vehicle. The vehicle departs through the departure point from a departure road stored beforehand in map data. The map data has map link information including multiple links. An exit point set unit sets an exit point on a link included in the map link information. The link corresponds to the departure point of the departure road identified by the identification unit. A learning unit learns a new road based on the exit point set by the exit point set unit and the travel locus of the vehicle.
Claims26
A vehicular navigation device comprising:
- an identification unit configured to identify a departure point through which a travel locus of a vehicle departs from a departure road stored beforehand in map data, the map data storing map link information including a plurality of links;
- an exit point set unit configured to set an exit point on a link included in the map link information, the link corresponding to the departure point of the departure road identified by the identification unit;
- and
- a learning unit configured to learn a new road based on the exit point set by the exit point set unit and the travel locus of the vehicle.
A vehicular navigation device comprising:
- an identification unit configured to identify an entry point through which a travel locus of a vehicle enters an entry road stored beforehand in map data, the map data storing map link information including a plurality of links;
- a return point set unit configured to set a return point on a link included in the map link information, the link corresponding to the entry point of the entry road identified by the identification unit;
- and
- a learning unit configured to learn a new road based on the return point set by the return point set unit and the travel locus of the vehicle.
A method for learning a new road for a vehicular navigation device, the method comprising:
- identifying a departure point through which a travel locus of a vehicle departs from a departure road stored beforehand in map data, the map data storing map link information including a plurality of links;
- setting an exit point on a link included in the map link information, the link corresponding to the identified departure point of the departure road;
- and
- obtaining a new road based on the set exit point and the travel locus of the vehicle to learn the new road.
A method for learning a new road for a vehicular navigation device, the method comprising:
- identifying an entry point through which a travel locus of a vehicle enters an entry road stored beforehand in map data, the map data storing map link information including a plurality of links;
- setting a return point on a link included in the map link information, the link corresponding to the identified entry point of the entry road;
- and
- obtaining a new road based on the set return point and the travel locus of the vehicle to learn the new road.
