IN-VEHICLE NAVIGATION IN COLLABORATION WITH A SERVER
First Claim
1. An in-vehicle navigation apparatus comprising:
- a map data storage unit configured to store map data;
a current position detecting unit configured to detect a current position of a vehicle associated with the in-vehicle navigation apparatus;
a charging point determining unit configured to determine whether the current position detected by the current position detecting unit is a charging point on the basis of charge information on the vehicle;
a charging point registering unit configured to;
register the charging point determined by the current position detecting unit anda charging point received from a server apparatus external from the in-vehicle navigation apparatus in the map data storage unit;
a transmission necessity determining unit configured to determine necessity for transmission of the charging point determined by the charging point determining unit to the server apparatus; and
a communicating unit configured to transmit the charging point determined to have the necessity for transmission by the transmission necessity determining unit to the server apparatus and receive a charging point from the server apparatus,wherein the transmission necessity determining unit determines the presence of public availability of the charging point by referring to the map data and determines that the charging point having the public availability has the necessity for transmission.

Abstract
An in-vehicle navigation apparatus to support sharing of electric vehicle charging point information such that other electric vehicles can use a charging point where its own electric vehicle is charged. If the in-vehicle navigation apparatus determines that a current position is a charging point on the basis of charge information about an electric vehicle, the navigation apparatus determines whether the charging point has public availability by referring to facility information, such as facility positions in map data stored in a map data storage unit. The in-vehicle navigation apparatus may transmit charging points having public availability to a server apparatus and not transmit the charging points having no public availability to the server apparatus. Vehicles may download charging points uploaded by other vehicles.

8. A server apparatus comprising:
-
a map data storage unit configured to store map data; a communicating unit configured to receive a first charging point from an in-vehicle navigation apparatus and transmit a second charging point to the in-vehicle navigation apparatus; a registration necessity determining unit configured to determine necessity for registration of the first charging point received from the in-vehicle navigation apparatus in the map data storage unit; and a charging point registering unit configured to register the first charging point determined to have the necessity for registration by the registration necessity determining unit in the map data storage unit, wherein the registration necessity determining unit determines the presence of public availability of the charging point by referring to the map data and determines that the charging point having the public availability has the necessity for registration. - View Dependent Claims (9, 10, 11)
