Abstract

A communication device is provided that is capable of accurately reporting which position a vehicle or a pedestrian exists in with respect to the local vehicle and of supporting safer driving.

A communication device mounted on a moving body includes: a communication unit that receives communication information according to a preset communication condition; a determination unit that determines whether a service is provided in accordance with the received communication information; and a display controller that displays display information needed to provide the service on a map displayed on a display unit, when the service is provided according to a result determined by the determination unit.

Claims

1. A communication device mounted on a moving body, the communication device comprising:

a memory that stores a program;

a radio that receives communication information according to a preset communication condition;

a processor that determines whether a service is provided in accordance with the received communication information, the processor executing a process according to the program;

a display controller that displays display information needed to provide the service on a map displayed on a display unit, when the service is provided according to a result determined by the processor; and

a detector that detects whether an emergency vehicle exists in accordance with the received communication information,

wherein the display controller displays an icon indicating the emergency vehicle on the map when existence of the emergency vehicle is detected, and

wherein the display controller enlarges the icon indicating the emergency vehicle over time on the map when the emergency vehicle approaches the moving body.

2. The communication device according to claim 1, wherein when the display information includes information relating to the moving body, the display controller displays the display information on the map according to a movement of the moving body.

3. The communication device according to claim 1,

wherein the processor specifies a travelling route of the emergency vehicle on the basis of a traveling rule, and

wherein the display controller performs:

displaying the specified travelling route on the map when the specified travelling route overlaps the travelling route of a vehicle mounted with the communication device; and

not displaying the specified travelling route when the specified travelling route does not overlap the travelling route of the vehicle mounted with the communication device.

4. The communication device according to claim 1, wherein the preset communication condition is that V2X information relating to V2X is communicated.

5. The communication device according to claim 1, wherein the communication information includes at least one of roadside machine information obtained from a roadside machine, moving body information obtained by the moving body, and emergency information obtained from an emergency information reporting system.

11. The communication device according to claim 1, wherein the communication information includes local-vehicle information on a basis of operating information of the moving body, another-vehicle information on a basis of operating information of an another vehicle from another communication device mounted in the another vehicle, and roadside machine information on a basis of a detection result in a surrounding environment of the moving body from a roadside machine installed in the surrounding environment of the moving body.

6. A non-transitory computer readable recording medium having recorded therein a communication program for causing a communication device mounted on a moving body to execute a process comprising:

receiving communication information according to a preset communication condition;

determining whether a service is provided in accordance with the received communication information; and

displaying display information needed to provide the service on a map displayed on a display unit, when the service is provided according to a determination result;

detecting whether an emergency vehicle exists in accordance with the received communication information;

displaying an icon indicating the emergency vehicle on the map when existence of the emergency vehicle is detected; and

enlarging the icon indicating the emergency vehicle over time on the map when the emergency vehicle approaches the moving body.

7. The non-transitory computer readable recording medium according to claim 6, wherein when the displaying the display information includes information relating to the moving body, the displaying the display information displays the display information on the map according to a movement of the moving body.

8. The non-transitory computer readable recording medium according to claim 6, the process further comprising:

specifying a travelling route of the emergency vehicle on the basis of a traveling rule,

wherein the displaying the display information comprises;

displaying the specified travelling route on the map when the specified travelling route overlaps the travelling route of a vehicle mounted with the communication device; and

not displaying the specified travelling route when the specified travelling route does not overlap the travelling route of the vehicle mounted with the communication device.

9. The non-transitory computer readable recording medium according to claim 6, wherein the preset communication condition is that V2X information relating to V2X is communicated.

10. The non-transitory computer readable recording medium according to claim 6, wherein the communication information includes at least one of roadside machine information obtained from a roadside machine, moving body information obtained by the moving body, and emergency information obtained from an emergency information reporting system.

12. The non-transitory computer readable recording medium according to claim 6, wherein the communication information includes local-vehicle information on a basis of operating information of the moving body, another-vehicle information on a basis of operating information of an another vehicle from another communication device mounted in the another vehicle, and roadside machine information on a basis of a detection result in a surrounding environment of the moving body from a roadside machine installed in the surrounding environment of the moving body.
