Techniques for providing replenishment point information

摘要

A portable communication terminal includes a current location/destination information acquirer that acquires current location information and destination information of a vehicle, a power source level information acquirer that acquires, from the vehicle, power source level information representing a remaining level of a power source, and a first transmitter that transmits the current location information, the destination information, and the power source level information to a server. A server includes a first receiver that receives, from the first transmitter, the current location information, the destination information, and the power source level information, an accumulator that accumulates past driving history information using the vehicle and a plurality of replenishment enable points representing positions where the power source of the vehicle can be replenished, a selector that selects, based on the current location information, the destination information, and the power source level information, which are received, and the accumulated driving history information, a replenishment point representing a position where the power source of the vehicle should be replenished from the plurality of replenishment enable points, and a second transmitter that transmits information about the selected replenishment point to the portable communication terminal.

1. An information processing system comprising a portable communication terminal and a server,
said portable communication terminal comprising:
a current location/destination information acquirer that acquires current location information and destination information of a vehicle;a power source level information acquirer that acquires power source level information representing a remaining level of a power source of said vehicle; anda first transmitter that transmits the current location information, the destination information, and the power source level information to the server, and said server comprising:a first receiver that receives the current location information, the destination information, and the power source level information;an accumulator that accumulates past driving history information using said vehicle and a plurality of replenishment enable points representing positions where the power source of said vehicle can be replenished;a selector that selects, based on the current location information, the destination information, and the power source level information, which are received, and the accumulated driving history information, a replenishment point representing a position where the power source of said vehicle should be replenished from the plurality of replenishment enable points;a second transmitter that transmits information about the selected replenishment point to said portable communication terminal; anda generator that generates, when the selector selects a first replenishment point and a second replenishment point that is located far apart from the first replenishment point with respect to the vehicle and that provides the power source less expensively than at the first replenishment point, information representing a route for said vehicle to reach the second replenishment point and a minimum necessary replenishment amount of the power source to be replenished at the first replenishment point to reach the second replenishment point.
