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.

First claim

What is claimed is:

1 . A vehicle security service provision method in a vehicle gateway to provide communication in a vehicle, comprising steps of:
determining whether or not an external device has been connected; transmitting an external device connection-informing message to a vehicle telematics unit through in-vehicle communication upon determination 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.

2 . The vehicle security service provision method according to claim 1 , wherein the step of determining whether or not the external device has been connected comprises sensing a voltage variation on an on-board diagnostics (OBD) connector connected to the vehicle gateway.

3 . The vehicle security service provision method according to claim 2 , wherein the determination, that the external device has been connected, is based on a voltage variation on an 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.

4 . The vehicle security service provision method according to claim 3 , wherein, when sixteenth and eighth pins provided at a connection terminal of the external device are shorted, the external device is connectable to the vehicle gateway via the OBD connector.

5 . The vehicle security service provision method according to claim 4 , 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.

6 . 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 unit.

7 . The vehicle security service provision method according to claim 6 , wherein the external device connection acceptance message is created by the user terminal, and is transferred to the vehicle gateway via the vehicle telematics unit.

8 . 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 unit, and discarding the diagnosis request message received from the external device in response to the external device connection rejection message.

9 . 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 unit, and executing the determining whether or not the external device has been connected, in response to the security setting request signal.

10 . The vehicle security service provision method according to claim 9 , 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 unit, and selection of a predetermined menu on a display screen of a designated user terminal.

11 . The vehicle security service provision method according to claim 1 , wherein, when the diagnosis request message is received through an on-board diagnostics (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.

12 . A vehicle security service provision method in a vehicle telematics unit linked with a vehicle gateway through a communication network in a vehicle, the method comprising steps of:
receiving an external device connection-informing message from the vehicle gateway; transferring the external device connection-informing message to a designated user terminal through a wireless network; receiving an external appliance connection acceptance message from the user terminal through the wireless network; and transferring the received external device connection acceptance message to the vehicle gateway.

13 . The vehicle security service provision method according to claim 12 , further comprising a step of:
determining whether or not there is a driver in the vehicle, in response to the received external device connection-informing message, and displaying a predetermined informing message to inform that the external device has been connected, through a display screen provided at the vehicle, when it is determined that there is a driver in the vehicle.

14 . The vehicle security service provision method according to claim 13 , wherein the step of determining whether or not there is a driver in the vehicle comprises determining whether or not a smart key of the driver has been sensed.

15 . The vehicle security service provision method according to claim 13 , wherein the step of determining whether or not there is a driver in the vehicle comprises determining whether or not a terminal of the driver has been paired to the vehicle.

16 . The vehicle security service provision method according to claim 12 , further comprising steps of:
receiving a security mode setting request signal from the user terminal before reception of the external device connection-informing message; and transferring the received security mode setting request signal to the vehicle gateway before reception of the external device connection-informing message.

17 . The vehicle security service provision method according to claim 16 , wherein the security mode is settable and releasable through inputting a predetermined button provided at at least one of a steering wheel of the vehicle and a room mirror of the vehicle.

18 . A computer-readable recording medium recorded with a program to execute the method according to claim 12 .

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

20 . A vehicle gateway for providing a vehicle security service in connection with a vehicle telematics unit, the vehicle gateway comprising:
a unit for checking whether or not an external device has been connected; a unit for transmitting an external device connection-informing message to the vehicle telematics unit through communication in a vehicle upon determination that the external device has been connected; a unit for receiving an external device connection acceptance message from the vehicle telematics unit; and a unit for processing a diagnosis request message received from the external device in response to the received external device connection acceptance message.

21 . The vehicle gateway according to claim 20 , wherein the vehicle gateway is connected to an on-board diagnostics (OBD) connector for connection of the external device, and senses a voltage variation on the OBD connector, to determine whether or not the external device has been connected.

22 . The vehicle gateway according to claim 21 , wherein the determination, that the external device has been connected, is based on a voltage variation on an input port o
