The operation of the vehicle position information providing device according to the embodiment of the present invention configured as described above will be described. First, a process of transmitting own vehicle position information to the management center from the detection of the own vehicle position of the vehicle is performed. In the car navigation device, the position of the vehicle is detected by a GPS receiver, a vehicle speed sensor, a gyro sensor, a map matching process, and the like (2a). The vehicle position information is edited into transmission information to be transmitted to the management center (2b). The car navigation device instructs the telephone unit to transmit the vehicle position information, and transmits the information to the management center by a mobile phone or a car phone (2c).

Next, from the reception of the vehicle position information at the center to the distribution of vehicle position information to each vehicle. The telephone unit receives own vehicle position information from each vehicle via a public telephone line (2d). Here, even if the vehicle position information management device receives the own vehicle position information, the vehicle position information management device does not distribute the own vehicle position information at that time, temporarily accumulates the own vehicle position information collected from each vehicle, and periodically stores the information at regular intervals. Send all vehicles at once. This reduces the load on satellite digital audio broadcasting. If the data size per unit is within 100 bytes, 250,000 units per channel can be transmitted in one second in satellite digital audio broadcasting in which one channel is 256 Kbytes. Therefore, if the update interval is 5 seconds, 125
Ten thousand vehicles can be transmitted. From the above, the vehicle position information management device accumulates own vehicle position information (2e).
At regular time intervals, the vehicle position information of all vehicles is edited into distribution information based on the latest information on the vehicle positions of all vehicles that have been accumulated so far (2j). The vehicle position information management device instructs the satellite digital audio broadcast transmitter to transmit the vehicle position information, and transmits the information to each vehicle by satellite digital audio broadcast (2k).

The transmission message from the management center to each vehicle is as follows:
As shown as an example in FIG. 4, a group identification number (3e) is given to the header part. This makes it possible to restrict information to be received only by vehicles in a specific group, such as vehicles in the same company. Further, a vehicle identification number (3d) is given. This makes it possible to limit the individual response information so that only the corresponding vehicle can receive it. In the data part, the position information (3f)
And a telephone number (3g). This is a telephone number of a mobile phone or a car phone owned by the vehicle, and this telephone number can be read and transmitted at the time of automatic telephone call and automatic data transmission processing in the vehicle.

Finally, display of vehicle position information, automatic communication, and automatic data transmission are performed from reception of vehicle position information in the vehicle. The satellite digital audio broadcast receiver receives vehicle position information from the management center (2l). The vehicle position information is transmitted from the satellite digital audio broadcast receiving device to the car navigation device, and a vehicle mark is displayed on a digital map on a display (2 m).

On the screen display of the vehicle dynamics management device, as shown in the example of FIG. 5, the traveling direction is represented by the direction of the arrow at the corresponding longitude / latitude coordinate position on the digital map 4a (4).
b). When the vehicle mark on the digital map is selected, a window for selecting automatic call or automatic data transmission is displayed (2n). It is determined whether the automatic call or the automatic data transmission is selected in the selection window (2o). If the selection is an automatic call, the telephone number added to the vehicle position information is read out for the corresponding vehicle, a call instruction is issued to the telephone unit, and the call is started (2).
p). If the selection is automatic data transmission, specify the transmission data such as electronic messages, map search results, and route search results, read the telephone number added to the vehicle location information for the relevant vehicle, and issue a call instruction to the telephone unit. Then, communication is started and data transmission is performed (2q).

As described above, in the embodiment of the present invention,
The vehicle position information providing device collects own vehicle position information in each vehicle, sends it to the management center using a mobile phone or a car phone, and transmits a plurality of vehicles to each vehicle using satellite digital audio broadcasting from the management center. Send vehicle position information,
Each vehicle refers to other vehicle position information, makes an automatic call with another vehicle, and performs automatic data transmission, so it distributes the position information of other vehicles to each vehicle and determines the vehicle position. Can be displayed. Further, by designating the vehicle mark, automatic communication and automatic data transmission can be easily performed, and information transmission between vehicles can be smoothly performed.
