Communication device, control method thereof, and communication system including the same

1. A communication device, comprising:

a communication unit configured to receive first path information from a first vehicle and to receive second path information from a second vehicle; and

a processor configured to:

determine a possibility of the first and second vehicles entering a predetermined area based on the first and second path information, and

based on the possibility being greater than a reference, transmit, through the communication unit, a message for controlling at least one of the first vehicle or the second vehicle to allow the first and second vehicles to enter the predetermined area at different time points,

based on the first and second path information, generate third path information for changing a route of at least one of the first vehicle or the second vehicle to allow the first and second vehicles to enter the predetermined area at the different time points, and

transmit the third path information to one of the first vehicle or the second vehicle such that (i) the first vehicle changes the route of the first vehicle from the first path information to the third path information based on the first vehicle receiving the third path information, or (ii) the second vehicle changes the route of the second vehicle from the second path information to the third path information based on the second vehicle receiving the third path information.

2. The device of claim 1 , wherein the processor is configured to control the communication unit to transmit at least a portion of the first path information to the second vehicle.

3. The device of claim 2 , wherein the processor is configured to:

determine a first portion of the first path information that satisfies a reference condition; and

transmit, to the second vehicle, a second portion of the first path information that does not include the first portion of the first path information.

4. The device of claim 3 , wherein the first portion of the first path information includes at least one of vehicle information corresponding to the first vehicle or personal information corresponding to a passenger in the first vehicle.

5. The device of claim 1 , wherein the processor is configured to:

select one of the first vehicle or the second vehicle based on the first and second path information; and

transmit the message to the selected one of the first vehicle or the second vehicle.

6. The device of claim 5 , wherein the processor is configured to:

select one of the first vehicle or the second vehicle that travels at a speed slower than a speed of the other of the first vehicle or the second vehicle.

7. The device of claim 5 , wherein the processor is configured to:

select one of the first vehicle or the second vehicle that has a communications service quality greater than a communications service quality of the other of the first vehicle or the second vehicle.

8. The device of claim 1 , wherein the processor is configured to:

select one of the first vehicle or the second vehicle that is capable of at least one of accelerating, decelerating, or changing a traveling direction without driver intervention; and

transmit the message to the selected one of the first vehicle or the second vehicle.

9. The device of claim 1 , wherein the predetermined area includes a lane corresponding to an intersection of a plurality of lanes.

10. The device of claim 1 , wherein the predetermined area includes a road without a centerline.

11. The device of claim 1 , wherein the message includes a speed control command for changing a speed of the at least one of the first vehicle or the second vehicle.

12. The device of claim 1 , wherein the first path information and the third path information include paths for the first vehicle that are different from each other, and

wherein the second path information and the third path information include paths for the second vehicle that are different from each other.

13. A control method comprising:

receiving first path information from a first vehicle;

receiving second path information from a second vehicle;

determining a possibility of the first and second vehicles entering a predetermined area based on the first and second path information; and

based on the possibility being greater than a reference, transmitting a message for controlling at least one of the first vehicle or the second vehicle to allow the first and second vehicles to enter the predetermined area at different time points;

based on the first and second path information, generating third path information for changing a route of at least one of the first vehicle or the second vehicle to allow the first and second vehicles to enter the predetermined area at the different time points; and

transmitting the third path information to one of the first vehicle or the second vehicle such that (i) the first vehicle changes the route of the first vehicle from the first path information to the third path information based on the first vehicle receiving the third path information, or (ii) the second vehicle changes the route of the second vehicle from the second path information to the third path information based on the second vehicle receiving the third path information.

14. The control method of claim 13 , further comprising:

determining a first portion of the first path information that satisfies a reference condition; and

transmitting, to the second vehicle, a second portion of the first path information that does not include the first portion of the first path information.

15. The control method of claim 14 , wherein the first portion of the first path information includes at least one of vehicle information corresponding to the first vehicle or personal information corresponding to a passenger in the first vehicle.

16. The control method of claim 13 , wherein transmitting the message comprises:

selecting one of the first vehicle or the second vehicle based on the first and second path information; and

transmitting the message to the selected one of the first vehicle or the second vehicle.

17. The control method of claim 13 , wherein the message includes a speed control command for changing a speed of the at least one of the first vehicle or the second vehicle.

18. The control method of claim 13 , further comprising setting the predetermined area based on a map data,

wherein the predetermined area includes at least one of a lane corresponding to an intersection of a plurality of lanes or a road without a centerline.

19. The control method of claim 13 , wherein the first path information and the third path information include paths for the first vehicle that are different from each other, and

wherein the second path information and the third path information include paths for the second vehicle that are different from each other.
