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 the user position from the schedule data. When the schedule is entered, the central processing unit 10 of the server stores the schedule data of the corresponding group from the information storage device 20,
The timetable data is read (step S11), and it is determined whether the moving 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. Similarly, the estimated arrival time of the position or the passing point is calculated for each predetermined time such as one hour, two hours, and the like, taking into account the target walking time, etc. (step S1).
4). Next, the calculated position information of the moving body is presented together with the map information (step S15). It is determined whether or not these position calculation processes have been performed for all users (step S16). If not completed, the process returns to step S12 to repeat the above process, and if completed, the position calculation process ends.

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 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,
The processing is performed to recalculate the position of each moving body and present it.

FIG. 6 is a diagram showing a display example of the position of the moving body presented by the server. In the illustrated example, the user A is displayed as ● and the user B is displayed as ○, but if the user's identifier is associated with the name or nickname and the name or nickname is displayed on the screen, the system becomes more familiar. Become. In this example, it is indicated that the user A is at the position P1 one hour after the movement start position P0, the position P2 after two hours, and the position P3 after three hours. Similarly, it indicates that the user B is at the position Q1 one hour after the movement start position Q0, at the position Q2 after two hours, and at the position Q3 after three hours. Of course, the position of each moving body may be calculated and presented in 30-minute units instead of in 1-hour units. Further, the estimated arrival time is displayed at the corresponding place for the passing point that is entered in the schedule data in advance. Although illustration is omitted, when the route search is performed on the server side and the recommended route is presented, the route is presented in a display mode that can be identified by a method such as highlighting, and the estimated position at every predetermined time is set. Present above.

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 the schedule data can be stored without going through the server. It is also possible to directly send schedule data from any mobile unit to another mobile unit. Once the schedule data of other mobile units are stored in each mobile unit, even if each mobile unit moves out of the communication range, the stored schedule data can be used to determine the position of the other mobile unit. It becomes possible to predict. In this case, 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, the same accurate position prediction is possible via the server. Become.

[0018]

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 of each user is collectively presented from the server, which facilitates mutual interaction. The position can be determined.
