Abstract

A vehicle security service provision method in a vehicle gateway to provide communication in a vehicle includes determining whether or not an external device has been connected, transmitting an external device connection-informing message to a vehicle telematics unit through the in-vehicle communication when it is determined that the external device has been connected, receiving an external device connection acceptance message from the vehicle telematics unit, and processing a diagnosis request message received from the external device in response to the received external device connection acceptance message. In accordance with the disclosed method, connection of an external device to the vehicle is sensed in real time. Sensed results are informed to a user terminal, for execution of a user approval procedure. Accordingly, an effective vehicle security service can be provided.

Claims

1. A vehicle security service provision method in a vehicle gateway having an input port for connection of an external device, comprising steps of:

determining, in the vehicle gateway, whether or not the external device has been connected based on a voltage variation on an on-board diagnostics (OBD) connector connected to the input port of the vehicle gateway under a condition that an eighth pin of the OBD connector is connected to the input port of the vehicle gateway;

transmitting, from the vehicle gateway, an external device connection-informing message to a vehicle telematics computer through an in-vehicle communication network upon determination that the external device has been connected;

receiving, in the vehicle gateway, an external device connection acceptance message from the vehicle telematics computer; and

processing, in the vehicle gateway, a diagnosis request message received from the external device in response to the received external device connection acceptance message,

wherein, when sixteenth and eighth pins provided at a connection terminal of the external device are shorted, the external device is determined to be connected to the vehicle gateway via the OBD connector.

2. The vehicle security service provision method according to claim 1, wherein the voltage variation on the input port is sensed when power is supplied to a sixteenth pin of the OBD connector such that the power supplied to the sixteenth pin of the OBD connector is transferred to the eighth pin of the OBD connector in accordance with the short circuit.

3. The vehicle security service provision method according to claim 1, wherein the external device connection-informing message is transferred to a designated user terminal by the vehicle telematics computer.

4. The vehicle security service provision method according to claim 3, wherein the external device connection acceptance message is created by the user terminal, and is transferred to the vehicle gateway via the vehicle telematics computer.

5. The vehicle security service provision method according to claim 1, further comprising a step of:

receiving an external device connection rejection message from the vehicle telematics computer, and discarding the diagnosis request message received from the external device in response to the external device connection rejection message.

6. The vehicle security service provision method according to claim 1, further comprising a step of:

receiving a security setting request signal from the vehicle telematics computer, and executing the determining whether or not the external device has been connected, in response to the security setting request signal.

7. The vehicle security service provision method according to claim 6, wherein the security setting request signal is generated in accordance with at least one of inputting of a predetermined button provided at a handle of the vehicle, inputting of a predetermined button provided at one side of a room mirror in the vehicle, selection of a predetermined menu on a display screen of the vehicle telematics computer, and selection of a predetermined menu on a display screen of a designated user terminal.

8. The vehicle security service provision method according to claim 1, wherein, when the diagnosis request message is received through the OBD connector, it is determined that the external device has been connected, and a control operation to prevent routing of the diagnosis request message is executed until the external device connection acceptance message is received.

9. A non-transitory computer-readable recording medium recorded with a program to execute the method according to claim 1.

10. A vehicle gateway for providing a vehicle security service for an external device in connection with a vehicle telematics computer, the vehicle gateway comprising:

an input port to connect an on-board diagnostics (OBD) connector; and

an in-vehicle communication port to connect the vehicle telematics computer,

wherein the vehicle gateway determines whether or not the external device has been connected based on a voltage variation on the OBD connector connected to the input port of the vehicle gateway under a condition that an eighth pin of the OBD connector is connected to the input port of the vehicle gateway, transmits an external device connection-informing message to the vehicle telematics computer through an in-vehicle communication port upon determination that the external device has been connected, receives an external device connection acceptance message from the vehicle telematics computer, and processes a diagnosis request message received from the external device in response to the received external device connection acceptance message, and

wherein when sixteenth and eighth pins provided at a connection terminal of the external device are shorted, the external device is determined to be connected to the vehicle gateway via the OBD connector.

11. The vehicle gateway according to claim 10, wherein the voltage variation on the input port is sensed when power is supplied to a sixteenth pin of the OBD connector such that the power supplied to the sixteenth pin is transferred to the eighth pin of the OBD connector in accordance with the short circuit.

12. The vehicle gateway according to claim 10, wherein

the vehicle gateway receives an external device connection rejection message from the vehicle telematics computer, and discards the diagnosis request message received from the external device in response to the external device connection rejection message.

13. The vehicle gateway according to claim 10, wherein the vehicle gateway receives a security setting request signal from the vehicle telematics computer, and

wherein the vehicle gateway checks whether or not an external device has been connected, in response to the security setting request signal.

14. The vehicle gateway according to claim 10, wherein the vehicle gateway is connected to an on-board diagnostics (OBD) connector for connection of the external device and, when the diagnosis request message is received through the OBD connector, the vehicle gateway determines that the external device has been connected, and executes a control operation to prevent routing of the diagnosis request message until the external device connection acceptance message is received.
