In the center station 20 which has received these pieces of information, the route information selecting unit 24 stores the positional information (primary information) of a plurality of main points stored in the route information storage unit 21 according to the needs unique to the specified destination. Point) is selected, transmitted to the mobile unit 1 and displayed on the display unit 12.

In the mobile unit 1, the main point is specified by touching the main point which should be the start point of the route information among the plurality of main points displayed by the display unit 12, and the information of the main point and the destination are specified. The information of is the position information input unit 14 described above.
Via the mobile communication unit 4 and then transmitted to the center station 20. Center station 20 above
In accordance with the main points and the destinations received via the center side communication unit 4, the route information selection unit 24
Then, from the route information stored in the route information storage unit 21, route information starting from the main point and reaching the destination is selected, transmitted to the mobile unit 1 and displayed on the display unit 12. In this way, a series of route information request operations is completed. That is, in this system, in order to minimize the information communicated by the operator, the route from the current position to the main point in the vicinity of the destination via the main road is set for each mobile unit 1.
It is supposed that the operator of J.D. Since the route information can be obtained by a series of route information requesting operations in this way, the route information can be easily obtained only by inputting the requested destination. Further, by providing the route information to the center station 20 from a store or the like, it may be utilized as a new advertising means.

The route information transmitted from the center station 20 at the end of the above-described route information request operation includes various information necessary for guiding to the destination, in addition to the information on the route itself. That is, in addition to route information, traffic lights, posts, billboards, banks, etc. on the road or structures facing the road,
Information that serves as a mark is added. By transmitting the marks other than the route information at the same time in this way, the operator can judge the suitability of his / her own moving route based on the marks, and can reach the destination more reliably.

As described above, in the present system, the operator basically determines the route from the current position to the main point independently, but when the operator does not know the route to the main point, etc. Is also able to distribute route information to reach the main points. That is, as a special case, the route information such as the main trunk road is stored in the route information storage unit 21 in consideration of the necessity of the operator and the request of the information provider,
It is possible to obtain the corresponding route information. The optimum route may be searched by the processing device of the center station 20. In this case, the center station 20 does not have to perform the process for all the existing routes, and the route search only needs to be performed in the basic map information, and the search efficiency is dramatically improved.

In the above route information searching operation, the explanation has been made on the assumption that information is communicated only between the mobile unit 1 and the center station 20, but in the present embodiment, the mobile units 1, 1 are used.
Information can be communicated with each other. The operation of transmitting / receiving the route information between the mobile units 1 and 1 will be described. FIG. 12 is a flow chart of this operation. First, between specific mobile units 1 and 1, request information for requesting route information to another mobile unit 1 via the route information input unit 16 of the mobile unit 1 on the receiving side (current position and purpose of the mobile unit 1). (Information indicating the route information to be received, which is composed of the ground, etc.) is input, and at the same time, the communication line is opened to the mobile body 1 on the transmitting side to request the transmission of the route information. If the transmission-side mobile unit 1 that has received this request information accepts the transmission of the route information, it notifies the reception-side mobile unit 1 of that fact. The mobile unit 1 on the receiving side closes the communication line when the transmission request is not accepted.

After that, in the mobile unit 1 on the transmitting side, the requested route information is selected from the route information held by the mobile unit 1 itself, the route information is transmitted to the mobile unit 1 on the receiving side, and at the same time, a map necessary for route display is displayed. After designating the range of information, the mobile unit 1
Close the communication line between. The designation of the range of the map information is performed almost in the same way as the operation of specifying the search range in the destination search operation described above. The specific operation by the basic map, the specific operation by the place name (prefecture name, city / ward name), the area It is performed by selecting any one of the specific actions by (prefecture, city) and the specific action by the current position.

In the mobile unit 1 on the receiving side, when the map information designated by the mobile unit 1 on the transmitting side is not included in the map information held by itself, the map information lacking in the center station 20 is displayed. Request. The request operation of the insufficient map information is performed by transmitting the range of the map information instructed by the mobile unit 1 on the transmitting side to the center station 20, and based on this map information, the control unit 23 of the center station 20. Then, the map information required by the mobile unit 1 is selected from the map information stored in the map information storage unit 27, and this map information is transmitted to the mobile unit 1 via the center station side communication unit 22. .

If there is a difference in the map information (difference in version, etc.) between the mobile bodies 1 on the transmitting side and the receiving side, it is treated as an error. By enabling the transmission and reception of the route information between the mobile bodies 1 in this way, the information held by the other mobile bodies 1 can be effectively utilized. In particular, when a plurality of moving bodies reach the same destination, each moving body can easily hold the same route information, and the operation of requesting the center station 20 for the route information can be omitted.

In addition, in the operation of transmitting and receiving information between the mobile units 1, the mobile unit 1 can create its own route information. That is, it is possible for the mobile unit 1 to create route information to a private home or other special destination not registered in the center station 20. For example, the input unit 7 is constituted by a pointing device such as a light pen. Then, using this, an arbitrary route on the map information displayed on the display unit 12 is marked to create route information. Further, a target structure such as a gas station or a post may be provided with a predetermined mark at a required position.

Alternatively, when the mobile unit 1 actually moves, within the allowable range of the memory allocated inside the mobile unit 1 (a process of several tens to several hundreds of kilometers).
The route information may be created by recording the route sequentially moved by. In this way, the route information can be arbitrarily created even for the specific destination not registered in the center station 20, so that the route information held by the mobile units 1 can be effectively transmitted between the mobile units 1. It is possible to utilize it, and an operator who is familiar with the route can provide route information by creating route information. Especially when the moving route of the moving body 1 is automatically recorded, the moving body 1
It can be used as a reference for determining the route of a multiple road. Services such as guidance for the following vehicles are possible.

In the present system, the route information in the moving body 1 is output not only by visual display on the display unit 12 but also by voice navigation using the voice transmitting unit 13 of the output unit 5. May be. That is,
By the voice transmission unit 13 of the output unit 5, "Turn right at the next intersection."-"Turn left at 100 meters."-"Go straight for 5 kilometers along the road."
・ Voice information such as "You have left the route to your destination. Please make a U-turn." By thus providing the route information by voice, the operator does not need to sequentially check the display unit 12, and the mobile unit 1
You can concentrate on the operation of and improve the safety.
