FIG. 3 is a view for explaining the data structure of the schedule entered in the server. FIG. 3A shows data of a plurality of registered groups (1 to n), which includes a group name (identifier) and the number of members of the group (number of users). Therefore, this system can be registered and used by multiple groups, and each group is distinguished by a name. FIG. 3B shows users (1 to 1) of each group.
In the schedule data of m), an identifier is attached to each user, and the movement start date and time, the movement start position, the expected arrival place, the desired arrival date and time, and the moving means are written. Date and time of movement start,
Enter the desired arrival date and time as ○ month × day △ hour □ minute. The movement start position is the position information detected by the current position detection device in the case of a vehicle equipped with a navigation device, or the address, road name, nearby intersection name, nearby facility name if the current position detection device is not provided. , Location information of a facility or the like searched by inputting a telephone number or a postal code. The expected arrival location is location information of a facility, a memory point, a facility searched by inputting a telephone number or a zip code, and includes not only the final arrival location (destination) but also a transit point on the route to reach it. .

FIG. 4 is a diagram for explaining a schedule data input process. Call the server on the network,
First, after inputting the registered group name (step S1), the user's identifier is input (step S2), and then the schedule data is input. The schedule data is input by inputting a movement start position, a planned arrival place, a movement start date and time, and a desired arrival date and time. When inputting continuous schedules, the arrival destination of the previous schedule may be recognized as the movement start position of the next schedule. In this case, the trouble of inputting the movement start position can be omitted. Then, it is determined whether or not all items of the schedule have been input (step S4),
When all the items have been input, the process ends.

FIG. 5 is an explanatory diagram of a processing flow for calculating a user position from schedule data and searching for a possible gathering position. When the schedule is entered, the central processing unit 10 of the server reads the schedule data and timetable data of the corresponding group from the information storage device 20 (step S11), and determines whether or not the transportation means of each user is a vehicle ( Step S12). When the means of transportation is a vehicle, the average vehicle speed is calculated from the travel distance and travel time obtained from the schedule data or from vehicle speed data obtained from the vehicle, and the position and the passage at predetermined time intervals such as one hour later and two hours later are passed. The estimated arrival time of the point is calculated for the journey to reach the expected arrival place of each mobile body (step S13). If the means of transportation is not a vehicle but public transportation, search for the transportation facility that corresponds to the planned arrival location such as the movement start position or transit point, search the corresponding timetable data from the movement start date and time, and obtain the average calculated in advance. In the same way, 1 hour later
The estimated arrival time of the position or the passing point at predetermined time intervals, such as two hours later, is calculated for the journey to the expected arrival place of each mobile body (step S14). It is determined whether these position calculation processes have been performed for all users (step S15),
If not, the process returns to step S12 to repeat the above process. Next, a position where the mobile body can be collected is searched for from the calculated positions of the mobile bodies (step S16), and the estimated position and the position where the mobile body can be collected are presented (step S1).

It is possible to more accurately recognize the position by updating the schedule data from the mobile unit at any time and calculating the position of each mobile unit and the settable position based on the updated data. Therefore, the central processing unit 10 goes to see the schedule at predetermined intervals, and when the data is updated, performs the processing of FIG. 5 to recalculate and present the position of each moving body and the position where it can collect. To do.

FIG. 6 is a diagram for explaining a display example of the estimated position and the settable position. In this example, it is assumed that the moving body (user) is a vehicle and ◯, Δ, and □ are estimated positions calculated by the users A, B, and C after a predetermined time. The gatherable position is a well-known facility or the like located in front of each user in the traveling direction and within a predetermined distance from each moving body.
2 and P3 are searched and presented as possible gathering sites.

It should be noted that the final decision of the optimum gathering position is made, for example, from P3 among the candidate sites presented by each user.
When it is determined to be optimal, it will be sent to the server,
On the server side, a method such as presenting that P3 has become the optimum gathering position may be used. When the server presents the settable position, for example, the candidate site P3 having the shortest total distance from each user to the settable position is determined to be the optimum set position, and the candidate site is set to another candidate site. May be presented in a distinguishable manner. When each user approves the presented candidate site P3, the server side presents that P3 has become the optimum gathering position. If some of the moving bodies use public transportation, the places where the public transportation users can go will be given priority to be presented as possible gathering sites, and the movement of each moving body (vehicle) The candidate site with the shortest total distance is set as the optimal set position.

In the above embodiment, the schedule data of a plurality of mobile units are stored in the server. However, each mobile unit is provided with a database in which schedule data can be written so that it does not go through the server. It is also possible to directly send schedule data from any mobile unit to another mobile unit. In this case, once the schedule data of other mobile units is stored in each mobile unit, even if each mobile unit moves out of the communication range, other mobile units can be stored using the stored schedule data. It becomes possible to predict the position of. Furthermore, if each mobile unit has a central processing unit having the same function as the server shown in FIG. 2, map-related data, and timetable data, each mobile unit can search for a position where it can collect. Therefore, it becomes possible to determine the optimum gathering position.

[0019]

As described above, according to the present invention, it is not necessary for a plurality of users who share a schedule to communicate with each other, and the position and gatherable position of each user are presented from the server. It becomes possible to judge the optimum position of each moving body by judging the mutual position.

If each mobile unit can store the schedule data of other mobile units and has the same function as the server, the stored schedule data can be used for other mobile units. It becomes possible to predict the position and further determine the optimum position of each moving body.
