The providing unit 303 generates a new route for the automobile 10 and determines whether or not the bicycle 20 is encountered when the automobile 10 travels on the new route. Even if there is a route that does not encounter the bicycle 20, for example, if the amount of increase in the mileage exceeds the allowable upper limit, it may be determined that the route does not exist. If an affirmative determination is made in step S104, the process proceeds to step S105, and if a negative determination is made, the process proceeds to step S106.

In step S105, the providing unit 303 generates the providing information. The provided information generated in step S105 includes a new route for the automobile 10. This new route is a route that avoids encountering the bicycle 20. On the other hand, in step S106, the providing unit 303 provides the providing information including the information about the point where the bicycle 20 is encountered. The provided information generated in this step S106 includes, for example, information regarding a position, a time, a time until the bicycle 20 is encountered, and the like. Then, the provided information generated in step S105 or step S106 is transmitted to the automobile 10 by the providing unit 303 in step S107.

Next, the process executed by the automobile terminal 100 will be described. FIG. 9 is a flowchart of a process executed by the automobile terminal 100 according to the present embodiment. The process shown in FIG. 9 is repeatedly executed by the automobile terminal 100 at predetermined time intervals. In the automobile terminal 100, it is assumed that the route guidance by the navigation unit 201 has already been executed.

In step S201, the navigation unit 101 acquires information about the current location, the destination, and the route. The current location is detected by the position information sensor 17. Further, the navigation unit 101 stores the destination input to the input unit 14 when the first user uses the route guidance in the auxiliary storage unit 13. In this step S201, the navigation unit 101 reads the destination stored in the auxiliary storage unit 13. Further, the navigation unit 101 generates a route based on the current location and the destination, and stores it in the auxiliary storage unit 13. In this step S201, the route stored in the auxiliary storage unit 13 is read.

Next, in step S202, the navigation unit 101 generates vehicle information. The navigation unit 101 associates the current location, the destination, and the route with the vehicle ID stored in the auxiliary storage unit 13 to generate vehicle information. The automobile ID is given in advance from the center server 30. In step S203, the navigation unit 101 transmits vehicle information to the center server 30.

In step S204, the navigation unit 101 determines whether or not the provided information is received from the center server 30. If an affirmative determination is made in step S204, the process proceeds to step S205, and if a negative determination is made, this routine is terminated. In step S205, the navigation unit 101 determines whether or not the provided information includes information regarding the new route. If an affirmative determination is made in step S205, the process proceeds to step S206, and if a negative determination is made, the process proceeds to step S207.

In step S206, the navigation unit 101 switches the guided route to a new route received from the center server 30. As a result, a new route is displayed on the display 15. On the other hand, in step S207, the navigation unit 101 causes the display 15 to display the time, position, or time until the bicycle 20 is encountered. At this time, the time until the encounter may be counted down.

The same process as that shown in FIG. 9 may be executed by the bicycle terminal 200. That is, by changing the route of the bicycle 20, it may be possible to prevent the automobile 10 from encountering the bicycle 20.

As described above, according to the present embodiment, it is possible to prevent the automobile 10 from encountering the bicycle 20. Further, when the automobile 10 encounters the bicycle 20, the first user is notified in advance, so that it is possible to suppress the encounter with the bicycle 20 without mental preparation.

<Other embodiments>
The above embodiment is merely an example, and the present disclosure may be appropriately modified and implemented without departing from the gist thereof.

The processes and means described in the present disclosure can be freely combined and carried out as long as there is no technical contradiction.

Further, the processing described as being performed by one device may be shared and executed by a plurality of devices. Alternatively, the process described as being performed by different devices may be performed by one device. In a computer system, it is possible to flexibly change what kind of hardware configuration (server configuration) is used to realize each function.

In the above embodiment, the example in which the route guidance is carried out in the automobile 10 has been described, but it is not essential that the route guidance is carried out in the automobile 10. For example, if the automobile 10 is on a single road, it can be predicted that the vehicle will continue to travel on that road. Therefore, since the position and time of encountering the bicycle 20 can be predicted by comparing the route with the route of the bicycle 20, such information may be transmitted to the automobile 10.

The present disclosure can also be realized by supplying a computer program having the functions described in the above embodiment to the computer, and reading and executing the program by one or more processors possessed by the computer. Such a computer program may be provided to the computer by a non-temporary computer-readable storage medium that can be connected to the computer's system bus, or may be provided to the computer via a network. The non-temporary computer-readable storage medium is, for example, an arbitrary type of disk such as a magnetic disk (floppy (registered trademark) disk, hard disk drive (HDD), etc.), an optical disk (CD-ROM, DVD disk, Blu-ray disk, etc.). Includes read-only memory (ROM), random access memory (RAM), EPROM, EEPROM, magnetic cards, flash memory, optical cards, and any type of medium suitable for storing electronic instructions.
