Method and system for acquiring additional information of map information
First Claim
1. A method for obtaining additional information pertaining to a route R along which a vehicle is traveling from a current location P to a destination D, said method comprising:
- acquiring, by an in-vehicle computer positioned within the vehicle, location information of the vehicle, said location information comprising the current location P of the vehicle;
transmitting, by the in-vehicle computer to a server via a network, the location information, movable range information, and selection criteria information, wherein a movable range C derivable from the movable range information is an area relative to the current location P in which the vehicle can travel from the current location P by using a remaining amount of fuel in the vehicle when the vehicle is at the current location, wherein a limited range F with respect to the route R is a function of the location information, the movable range information, and the selection criteria information, and wherein the selection criteria information constrains the limited range F to be a subset of the movable range C that is less than the movable range C; and
receiving, by the in-vehicle computer from the server, additional information limited to information concerning locations within the limited range F.

Abstract
A method for obtaining additional information pertaining to a route along which a vehicle is traveling from a current location to a destination. Location information of the vehicle, which includes the current location, is acquired by an in-vehicle computer within the vehicle. The in-vehicle computer transmits to a server via a network: the location information, movable range information, and selection criteria information. A movable range derivable from the movable range information is an area relative to the current location in which the vehicle can travel from the current location by using a remaining amount of fuel in the vehicle when the vehicle is at the current location. A limited range with respect to the route is a function of the location information, the movable range information, and the selection criteria information. The in-vehicle computer receives, from the server, additional information limited to information concerning locations within the limited range.

11. A method for providing additional information pertaining to a route R along which a vehicle is traveling from a current location P to a destination D, said method comprising:
-
receiving, by a server from an in-vehicle computer via a network, location information of the vehicle, movable range information, and selection criteria information, wherein the in-vehicle computer is positioned within the vehicle, wherein the location information comprises the current location P of the vehicle, wherein a movable range C derivable from the movable range information is an area relative to the current location P in which the vehicle can travel from the current location P by using a remaining amount of fuel in the vehicle when the vehicle is at the current location;
determining a limited range F with respect to the route R, wherein said determining the limited range F comprises utilizing the location information, the movable range information, and the selection criteria, and wherein the selection criteria information constrains the limited range F to be a subset of the movable range C that is less than the movable range C; and
transmitting, by the server to the in-vehicle computer, additional information limited to information concerning locations within the limited range F. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
