System zur Fahrzeugüberwachung

摘要

A vehicle tracking system, wherein with respect to vehicles owned by members on which communication units containing GPS receivers are mounted, the vehicle tracking system specifies a previously-registered member and the vehicle owned by the previously-registered member based upon a request of the previously-registered member for providing positional information of a vehicle owned by the previously-registered member, and the vehicle tracking system executes a polling operation of positional information to the vehicle owned by the previously-registered member; retrieves an existence position of the vehicle on a map from a map database based upon positional information transmitted from the vehicle owned bythe previously-registered member; displays the existence position of the vehicle by superimposing on the map; and provides the existence position superimposed on the map as vehicle positional information data to the previously-registered member.
