Abstract

A vehicle and method of platooning control therefor are provided to achieve optimum communication charge efficiency while a plurality of vehicles perform platooning. A data communication method of a platooning vehicle includes starting platooning by a plurality of vehicles and sharing data charge rate information through a first protocol for vehicle-to-vehicle communication (V2V) by the plurality of vehicles. A first master vehicle and at least one slave vehicle are determined based on the shared data charge rate information. An access point (AP) is then activated according to a second protocol for short distance communication by the first master vehicle and an AP of the master vehicle is accessed and data communication is performed by the at least one slave vehicle.

First claim

What is claimed is:

1. A data communication method of a platooning vehicle, comprising:
starting platooning by a plurality of vehicles;
sharing data charge rate information through a first protocol for vehicle-to-vehicle communication (V2V) by the plurality of vehicles;
determining a first master vehicle and at least one slave vehicle among the plurality of vehicles based on the shared data charge rate information;
activating an access point (AP) according to a second protocol for short distance communication by the first master vehicle; and
accessing an AP of the master vehicle and performing data communication by the at least one slave vehicle,
wherein the determining of the first master vehicle includes determining a vehicle using a most inexpensive data charge rate among the plurality of vehicles as the first master vehicle.

2. The method of claim 1 , wherein the first master vehicle is connected to a base station and is configured to activate the AP based on a third protocol for wireless data communication.

3. The method of claim 2 , wherein the AP according to the second protocol includes a Wi-Fi hotspot.

4. The method of claim 1 , further comprising:
when connection with an AP of the first master vehicle is terminated in the at least one slave vehicle, setting a second master vehicle among the slave vehicles, connection of which is terminated.

5. The method of claim 4 , further comprising:
after setting the second master vehicle among the slave vehicles, connection of which is terminated, re-accessing the AP of the first master vehicle when it is possible to re-access the AP of the first master vehicle.

6. The method of claim 1 , further comprising:
when the first master vehicle is determined and then a preset condition of updating charge rate information is satisfied, updating the charge rate information between the plurality of vehicles.

7. The method of claim 6 , further comprising determining whether the first master vehicle is changed according to the updated charge rate information.

8. The method of claim 6 , the condition of updating charge rate information is satisfied includes at least one of a new vehicle joining the platooning, a residual data capacity of the first master vehicle being equal to or less than a predetermined level, and a predetermined period elapsing.

9. A non-transitory computer-readable recording medium having recorded thereon a program for executing the method of claim 1 .

10. A vehicle, comprising:
a communicator including a first communication module configured to support a first protocol for vehicle-to-vehicle communication (V2V), and a second communication module configured to support a second protocol for short distance communication;
a first controller configured to execute platooning based on information acquired through the at least one communicator; and
a second controller when the platooning with at least one another vehicle is started, configured to:
share data charge rate information with the at least one another vehicle through the first communication module;
determine whether a vehicle is a first master vehicle or a slave vehicle based on the shared data charge rate information; and
activate an access point (AP) that the at least one another vehicle determined as the slave vehicle is capable of accessing, through the second communication module, in response to determining the vehicle as the first master vehicle;
wherein the second controller is configured to determine the vehicle as the first master vehicle when a charge rate of the vehicle is a most inexpensive charge rate among the shared charge rate information, and determine the vehicle as the slave vehicle when a charge rate of the at least one another vehicle is most inexpensive.

11. The vehicle of claim 10 , wherein the communicator further includes:
a third communication module configured to support a third protocol for wireless data communication;
wherein, in response to determining the vehicle as the first master vehicle, and
wherein the second controller is connected to a base station through the third communication module and is configured to activate the AP.

12. The vehicle of claim 11 , wherein an AP according to the second protocol includes a Wi-Fi hotspot.

13. The vehicle of claim 10 , wherein, in response to determining the vehicle as the slave vehicle, the second controller is configured to access an AP of the first master vehicle and perform data communication; and wherein, when connection with the AP is terminated, the second controller is configured to determine whether a vehicle is a second master vehicle or a slave vehicle with respect to the second master vehicle.

14. The vehicle of claim 13 , wherein, in response to determining the vehicle as the slave vehicle with respect to the second master vehicle, the second controller is configured to access an AP of the second master vehicle and then access an AP of the first master vehicle when it is possible to re-access the AP of the first master vehicle.

15. The vehicle of claim 10 , wherein, in response to determining the vehicle as the master vehicle, the second controller is configured to update the at least one another vehicle and charge rate information when a preset condition of updating the charge rate information is satisfied.

16. The vehicle of claim 15 , wherein the second controller is configured to determine whether the first master vehicle is changed based on the updated charge rate information.

17. The vehicle of claim 15 , the condition of updating charge rate information is satisfied includes at least one a new vehicle joining the platooning, a residual data capacity of the first master vehicle being equal to or less than a predetermined level, and a predetermined period elapsing.
