Vehicle tracking system, vehicle-theft warning system, stolen-vehicle tracking system, and theft-warning vehicle tracking system

A vehicle tracking system, wherein

• with respect to vehicles owned by members on which communication units containing GPS receivers are mounted,
• when a positional information providing request for providing positional information of a vehicle owned by a member which has previously been registered into a management company by specifying a member code is transmitted to the management company, with applying the member code to the positional information providing request, the positional information providing request is transmitted to the management company and transmitted to a map distribution company;
• the management company specifies the member and the vehicle owned by the member based upon the vehicle positional information providing request, and executes a polling operation of the positional information with respect to the vehicle owned by the member;
• the management company transmits a result of the polling operation of the positional information with respect to the vehicle owned by the member to the map distribution company, applying the member code thereto;
• and
• in the case that a transmission code of the vehicle positional information providing request transmitted from the member is made coincident with a transmission code of the vehicle positional information providing request transmitted from the management company, the map distribution company retrieves a current position of the vehicle on a map from a map database based upon the positional information of the vehicle owned by the member, which is transmitted from the management company;
• displays the current position of the vehicle by superimposing on the map;
• and transmits the current position of the vehicle as vehicle positional information to the member.

A vehicle-theft warning system, wherein

• with respect to vehicles owned by members, on which communication units containing GPS receivers are mounted,
• based upon a move monitoring request issued from a terminal of a previously-registered member by inputting an ID code, a vehicle number of a vehicle owned by the previously registered member, and parking time,
• the vehicle-theft warning system specifies the previously-registered member, the vehicle owned by the previously-registered member, and a position of the vehicle owned by the previously-registered member;
• executes a polling operation of positional information in a periodic manner with respect to the vehicle owned by the previously-registered member;
• retrieves and stores a current position of the vehicle on a map from a map database based upon the positional information transmitted from the vehicle owned by the previously-registered member;
• and produces a warning notice by employing an electronic appliance mounted on the vehicle in such a case that the current position of the vehicle is changed within the parking time which is previously registered by the member.

A stolen-vehicle tracking system, wherein

• with respect to vehicles owned by members, on which communication units containing GPS receivers are mounted,
• based upon a move monitoring request issued from a terminal of a previously-registered member by inputting an ID code, a vehicle number of a vehicle owned by the previously-registered member, and parking time,
• the vehicle-theft warning system specifies the previously-registered member, the vehicle owned by the previously-registered member, and a position of the vehicle owned by the previously-registered member;
• executes a polling operation of positional information in a periodic manner with respect to the vehicle owned by the previously-registered member;
• retrieves and stores a current position of the vehicle on a map from a map database based upon the positional information transmitted from the vehicle owned by the previously-registered member;
• and notifies a move of the vehicle position to the terminal of the previously-registered member when the current position of the vehicle is changed within the parking time which is previously registered by the member;
• and displays the current position of the vehicle by superimposing on the map on the terminal of the member, so that present vehicle position information data is provided to the previously-registered member.

A vehicle-theft warning system, wherein

• based upon a move monitoring request issued from a terminal of a previously-registered member by inputting an ID code, a vehicle number of a vehicle owned by the previously-registered member, and parking time,
• the vehicle-theft warning system specifies the previously-registered member, the vehicle owned by the previously-registered member, and a position of the vehicle owned by the previously-registered member;
• executes a polling operation of positional information in a periodic manner with respect to the vehicle owned by the previously-registered member;
• retrieves and stores a current position of the vehicle on a map from a map database based upon the positional information transmitted from the vehicle owned by the previously-registered member;
• and produces a warning notice by employing an electronic appliance mounted on the vehicle in such a case that a passenger of the vehicle exits the vehicle and locks a door thereof, and thereafter, a self-weight of the vehicle is changed.

• retrieves and stores a current position of the vehicle on a map from a map database based upon the positional information transmitted from the vehicle owned by the previously-registered member;
• signals to the terminal a change in vehicle weights in the case that a passenger of the vehicle exits the vehicle and locks a door thereof, and thereafter, a self-weight of the vehicle is changed;
• notifies a move of a vehicle position to the terminal of the member in such a case that a current position of the vehicle is changed from a parking position which is previously registered by the previously-registered member;
• and displays the current position of the vehicle on the terminal of the member, while superimposing the current position on a map, so that present vehicle positional information data to the previously-registered member.
