Abstract

A vehicle communication control device includes a processor configured to acquire disaster information, control a communication state between a vehicle and an information distribution server; and restrict communication between the vehicle and the information distribution server when the vehicle is located in a disaster-stricken area.

First claim

The invention claimed is:

1. A vehicle communication control device, comprising
a processor configured to:
acquire disaster information;
control a communication state between a vehicle and an information distribution server; and
restrict communication between the vehicle and the information distribution server when the vehicle is located in a disaster-stricken area, wherein

the vehicle communication control device is provided outside the vehicle,
for a plurality of vehicles located in the disaster-stricken area, the processor is configured to
restrict communication between a part of the vehicles and the information distribution server, and
not restrict communication between remaining vehicles of the plurality of vehicles and the information distribution server, and

the remaining vehicles include an emergency vehicle.

2. The vehicle communication control device according to claim 1 , wherein
the processor is configured to instruct the vehicle to restrict communication from the vehicle to the information distribution server when the vehicle is located in the disaster-stricken area.

3. The vehicle communication control device according to claim 1 , wherein
the processor is configured to restrict communication from the information distribution server to the vehicle when the vehicle is located in the disaster-stricken area.

4. The vehicle communication control device according to claim 1 , wherein
the processor is configured to increase a ratio of the part of the vehicles to the plurality of vehicles when a degree of damage in the disaster-stricken area is large compared to when the degree of damage in the disaster-stricken area is small.

5. The vehicle communication control device according to claim 1 , wherein
the remaining vehicles further include a vehicle having a degree of damage equal to or greater than a predetermined value.

6. A vehicle communication control method executed by a computer, the method comprising:
obtaining disaster information;
restricting communication between a vehicle and an information distribution server when the vehicle is located in a disaster-stricken area; and
for a plurality of vehicles located in the disaster-stricken area,
restricting communication between a part of the vehicles and the information distribution server, and
not restricting communication between remaining vehicles of the plurality of vehicles and the information distribution server, wherein

the computer being a vehicle communication control device is provided outside the vehicle, and
the remaining vehicles include an emergency vehicle.

7. A non-transitory recording medium having recorded thereon a computer program for vehicle communication control, the computer program causing a computer to:
obtain disaster information;
restrict communication between a vehicle and an information distribution server when the vehicle is located in a disaster-stricken area; and
for a plurality of vehicles located in the disaster-stricken area,
restrict communication between a part of the vehicles and the information distribution server, and
not restrict communication between remaining vehicles of the plurality of vehicles and the information distribution server, wherein

the computer being a vehicle communication control device is provided outside the vehicle, and
the remaining vehicles include an emergency vehicle.
