Patent ID: 7066216

Claim:
A system for allocating fuel stations to movable bodies comprising: an onboard unit which is mounted on a movable body, the onboard unit storing and updating information about the movable body; a station unit disposed at a fuel station which supplies fuel to the movable body, the station unit storing and updating information about the fuel station; and a server which is connected to the onboard unit and the station unit through networks, the server allocating certain fuel stations to the movable body which requires fueling, based on the information about the movable body received from the onboard unit and the information about the fuel station received from the station unit; wherein the information about the movable body comprises an amount of remaining fuel and a position of the movable body, wherein the information about the fuel station comprises an amount of stored fuel and a position of the fuel station, wherein the server calculates not only a movable distance for the movable body based on information comprising the amount of remaining fuel, but also a station distance, which represents a distance between the movable body and the fuel station, based on the positions of the movable body and the fuel station, and wherein when a difference of distance resulting from a subtraction, the movable distance minus the station distance, is smaller than a certain threshold, the server determines a necessity of supplying fuel to the movable body, allocating a fuel station which keeps an amount of stored fuel necessary for fuelling the movable body.
