Server device, in-vehicle device, information processing method, and storage medium

1. A server device configured to communicate with a communication device mounted in a vehicle, the server device comprising a controller configured to execute:

acquiring a position of an emergency vehicle;

identifying a non-emergency vehicle at a predetermined distance from the acquired position of the emergency vehicle; and

transmitting, to a communication device mounted in the non-emergency vehicle, a request as information requiring the non-emergency vehicle to stop use of wireless communication.

2. The server device according to claim 1 , wherein the request includes information indicating a communication stop time as a time during which the use of the wireless communication is stopped.

3. The server device according to claim 2 , wherein the controller is configured to calculate the communication stop time based on at least one of a traveling speed of the emergency vehicle and congestion information of a route along which the emergency vehicle is traveling.

4. The server device according to claim 1 , wherein the controller is configured to transmit the request to the communication device of the non-emergency vehicle only when the position of the emergency vehicle is outside an area where a predetermined communication system is usable.

5. The server device according to claim 2 , wherein the controller is configured to transmit the request to the communication device of the non-emergency vehicle only when the position of the emergency vehicle is outside an area where a predetermined communication system is usable.

6. The server device according to claim 3 , wherein the controller is configured to transmit the request to the communication device of the non-emergency vehicle only when the position of the emergency vehicle is outside an area where a predetermined communication system is usable.

7. An in-vehicle device mounted in an emergency vehicle and configured to communicate with a device outside the emergency vehicle, the in-vehicle device comprising:

a controller configured to transmit, to a communication device mounted in a non-emergency vehicle, a request as information requiring the non-emergency vehicle to stop use of wireless communication when the non-emergency vehicle is a predetermined distance from a position of the emergency vehicle.

8. The in-vehicle device according to claim 7 , further comprising a short-distance communication device configured to transmit the request to the non-emergency vehicle.

9. The in-vehicle device according to claim 8 , wherein the predetermined distance from the position of the emergency vehicle is equal to a communicable range of the short-distance communication device.

10. The in-vehicle device according to claim 7 , wherein the request includes information indicating a communication stop time as a time during which the use of the wireless communication is stopped.

11. The in-vehicle device according to claim 10 , wherein the controller is configured to calculate the communication stop time based on at least one of a traveling speed of the emergency vehicle and congestion information of a route along which the emergency vehicle is traveling.

12. The in-vehicle device according to claim 9 , wherein the request includes information indicating a communication stop time as a time during which the use of the wireless communication is stopped.

13. The in-vehicle device according to claim 7 , wherein the controller is configured to transmit the request to the communication device of the non-emergency vehicle only when the position of the emergency vehicle is outside an area where a predetermined communication system is usable.

14. The in-vehicle device according to claim 9 , wherein the controller is configured to transmit the request to the communication device of the non-emergency vehicle only when the position of the emergency vehicle is outside an area where a predetermined communication system is usable.

15. An information processing method comprising:

acquiring a position of an emergency vehicle;

specifying a non-emergency vehicle at a predetermined distance from the acquired position of the emergency vehicle; and

transmitting a request as information requiring the non-emergency vehicle to stop use of wireless communication to a communication device mounted in the non-emergency vehicle.

16. The information processing method according to claim 15 , wherein the request includes information indicating a communication stop time as a time during which the use of the wireless communication is stopped.

17. The information processing method according to claim 16 , wherein the communication stop time is based on at least one of a traveling speed of the emergency vehicle and congestion information of a route along which the emergency vehicle is traveling.

18. The information processing method according to claim 15 , wherein the request is only transmitted to the communication device of the non-emergency vehicle in a case where the position of the emergency vehicle is outside an area where a predetermined communication system is usable.

19. The information processing method according to claim 16 , wherein the request is only transmitted to the communication device of the non-emergency vehicle in a case where the position of the emergency vehicle is within an area where a predetermined communication system is usable.

20. The information processing method according to claim 17 , wherein the request is only transmitted to the communication device of the non-emergency vehicle in a case where the position of the emergency vehicle is within an area where a predetermined communication system is usable.
