Abstract

A method of controlling a Wi-Fi device in a vehicle, which includes determining, via a controller of the Wi-Fi device, an abnormal state of the vehicle; adding, via the controller, vendor specific data in a management frame to be transmitted to a different Wi-Fi device in a different vehicle via Wi-Fi Direct based on the determined abnormal state; transmitting, via a wireless communication unit of the Wi-Fi device, the generated vendor specific data to the different Wi-Fi device, wherein the management frame comprises at least one of a probe request frame, a probe response frame, a service request frame and a service response frame, and wherein the management frame is transmitted before an authenticated connection is established between the Wi-Fi device and the different Wi-Fi device.

Claims

1. A method of controlling a Wi-Fi device in a vehicle, the method comprising:

determining, via a controller of the Wi-Fi device, an abnormal state of the vehicle;

adding, via the controller, vendor specific data in a management frame to be transmitted to a different Wi-Fi device in a different vehicle via Wi-Fi Direct based on the determined abnormal state;

transmitting, via a wireless communication unit of the Wi-Fi device, the generated vendor specific data to the different Wi-Fi device,

wherein the management frame comprises at least one of a probe request frame, a probe response frame, a service request frame and a service response frame, and

wherein the management frame is transmitted before an authenticated connection is established between the Wi-Fi device and the different Wi-Fi device.

2. The method of claim 1, wherein the vendor specific data is included in an IE (information element) of the management frame.

3. The method of claim 2, wherein the IE of the management frame further includes a “

Subelement”

field, and

wherein the “

Subelement”

field includes a vehicle abnormality information indicating the determined vehicle abnormal state.

4. The method of claim 3, wherein the vehicle abnormality information comprises at least one of a brake abnormality, an engine system abnormality, a driver status abnormality, a powertrain abnormality, a turn signal abnormality, an emergency notification, an abnormal vehicle driving, and a vehicle fire notification.

5. The method of claim 3, wherein the “

Subelement”

comprises a “

Subelement ID”

field including attribute information of the “

Subelement”

, a length field including length information, and a “

Subelement body”

field including vehicle abnormality information.

6. The method of claim 1, wherein the management frame is generated using a GAS (generic advertisement service) initial request frame and a GAS initial response frame defined in IEEE 802.11u.

7. A Wi-Fi device in a vehicle, comprising:

a wireless communication unit configured to communicate with a different Wi-Fi device in a different vehicle based on Wi-Fi Direct;

a sensing unit configured to determine an abnormal state of the vehicle; and

a controller configured to;

add vendor specific data in a management frame to be transmitted to the different Wi-Fi device via the Wi-Fi Direct based on the determined abnormal state,

transmit the generated vendor specific data to the different Wi-Fi device via the wireless communication unit,

wherein the management frame comprises at least one of a probe request frame, a probe response frame, a service request frame and a service response frame, and

wherein the management frame is transmitted before an authenticated connection is established between the Wi-Fi device and the different Wi-Fi device.

8. The Wi-Fi device of claim 7, wherein the vendor specific data is included in an IE (information element) of the management frame.

9. The Wi-Fi device of claim 8, wherein the IE of the management frame further includes a “

Subelement”

field, and

wherein the “

Subelement”

field includes a vehicle abnormality information indicating the determined vehicle abnormal state.

10. The Wi-Fi device of claim 9, wherein the vehicle abnormality information comprises at least one of a brake abnormality, an engine system abnormality, a driver status abnormality, a powertrain abnormality, a turn signal abnormality, an emergency notification, an abnormal vehicle driving, and a vehicle fire notification.

11. The Wi-Fi device of claim 9, wherein the “

Subelement”

comprises a “

Subelement ID”

field including an attribute information of the “

Subelement”

, a length field including length information, and a “

Subelement body”

field including vehicle abnormality information.

12. The Wi-Fi device of claim 7, wherein the management frame is generated using a GAS (generic advertisement service) initial request frame and a GAS initial response frame defined in IEEE 802.11u.
