Abstract

The present invention relates to: a vehicle capable of providing a wireless vehicle communication (V2X) service by using a mobile terminal without comprising a wireless communication module; a control method therefor; and a mobile terminal for the same. A method by which a mobile terminal provides V2X, related to one embodiment of the present invention, can comprise the steps of: acquiring, by the mobile terminal, vehicle information from a vehicle through near-field communication (NFC); and relaying V2X data between individuals outside of the vehicle by using a mobile communication module on the basis of the acquired vehicle information.

Claims

1. A method for providing vehicle wireless communication by a mobile terminal, the method comprising:

obtaining, by the mobile terminal, vehicle information from a vehicle through near field communication (NFC); and

relaying vehicle wireless communication (V2X) data between the vehicle and an external entity using a mobile communication module based on the obtained vehicle information.

2. The method of claim 1, wherein the vehicle comprises a wireless charging module,

wherein the wireless charging module comprises an NFC module configured to perform NFC communication with the mobile terminal when the mobile terminal is placed on the wireless charging module, and

wherein the mobile terminal is configured to obtain the vehicle information through the NFC module disposed on the wireless charging module.

3. The method of claim 2, wherein the relayed V2X data is exchanged with the vehicle through the NFC module and a short-range communication module of the mobile terminal.

4. The method of claim 1, wherein when the obtained vehicle information indicates that a mobile communication module for V2X services is not mounted on the vehicle, relaying is automatically performed.

5. The method of claim 1, further comprising:

detecting different peripheral terminals; and

instructing at least one different terminal selected based on the detection result to deactivate V2X operation.

6. The method of claim 1, wherein relaying comprises performing dedicated short-range communication (DSRC) for the V2X data.

7. The method of claim 1, wherein the obtained vehicle information comprises at least one of information on whether V2X mode is used, information on whether a mobile communication module is mounted, and access information of an alternative wireless communication means prepared for a situation in which the NFC communication is disabled.

8. The method of claim 7, wherein the access information of the alternative wireless communication means comprises a Bluetooth device (BD) address of the vehicle, a Wi-Fi media access control (MAC) address, and an access password.

9. The method of claim 7, further comprising, when the NFC communication is disabled, relaying the V2X data using the access information of the alternative wireless communication means.

10. The method of claim 9, further comprising displaying the situation in which the NFC communication is disabled and the access information of the alternative wireless communication means on a display unit.

11. A mobile terminal, comprising:

a short-range communication module configured to obtain vehicle information;

a mobile communication module; and

a controller configured to cause the mobile communication module to relay vehicle wireless communication (V2X) data between a vehicle and an external entity based on the obtained vehicle information.

12. The mobile terminal of claim 11, wherein the vehicle comprises a wireless charging module,

wherein the wireless charging module comprises an NFC module configured to perform NFC communication with the mobile terminal when the mobile terminal is placed on the wireless charging module, and

wherein the mobile terminal is configured to obtain the vehicle information through the NFC module disposed on the wireless charging module.

13. The mobile terminal of claim 12, wherein the relayed V2X data is exchanged with the vehicle through the NFC module and the short-range communication module of the mobile terminal.

14. The mobile terminal of claim 11, wherein when the obtained vehicle information indicates that a mobile communication module for V2X services is not mounted on the vehicle, the controller is configured to automatically relay the V2X data.

15. The mobile terminal of claim 11, further comprising a wireless Internet module, wherein the controller is configured to detect different peripheral terminals through the wireless Internet module and instruct at least one detected different terminal to deactivate V2X operation.

16. The mobile terminal of claim 11, wherein the controller is configured to perform dedicated short-range communication (DSRC) for the V2X data using the mobile communication module.

17. The mobile terminal of claim 11, wherein the obtained vehicle information comprises at least one of information on whether V2X mode is used, information on whether a mobile communication module is mounted, and access information of an alternative wireless communication means prepared for a situation in which the NFC communication is disabled.

18. The mobile terminal of claim 17, wherein the access information of the alternative wireless communication means comprises a Bluetooth device (BD) address of the vehicle, a Wi-Fi media access control (MAC) address, and an access password.

19. The mobile terminal of claim 17, wherein when the NFC communication is disabled, the controller is configured to relay the V2X data using the access information of the alternative wireless communication means.

20. The mobile terminal of claim 19, further comprising a display unit, wherein the controller is configured to cause the display unit to display the situation in which the NFC communication is disabled and the access information of the alternative wireless communication means.
