Abstract

A telematics system using a home network system and a control method thereof are provided. The telematics system includes: a home server for receiving a vehicle information signal, and transmitting a vehicle control signal; a home network center for receiving and transmitting the vehicle control signal, and receiving and transmitting the vehicle information signal; a telematics service center for receiving and transmitting the vehicle control signal, receiving and transmitting the vehicle information signal,; and a telematics terminal for receiving the vehicle control signal, confirming a variety of vehicle information, generating a vehicle information signal having the vehicle information, and again transmitting the generated vehicle information signal.

Claims

1. A telematics system using a home network system in a wire and wireless communication network that has a mobile communication network and an Internet network, the telematics system comprising:

a home server for receiving a vehicle information signal from a vehicle through the Internet network depending on a key pressed by a user, and transmitting a vehicle control signal to the vehicle;

a home network center for receiving the vehicle control signal from the home server, transmitting the received vehicle control signal to a telematics service center through the Internet network, receiving the vehicle information signal from the telematics service center in response to the vehicle control signal, and transmitting the received vehicle information signal to the home server;

the telematics service center for receiving the vehicle control signal from the home network center, transmitting the received vehicle control signal to a telematics terminal installed within the vehicle, through the mobile communication network, receiving the vehicle information signal from the telematics service center in response to the vehicle control signal, and transmitting the received vehicle information signal to the home network center through the Internet network; and

the telematics terminal for receiving the vehicle control signal from the home server, confirming a variety of vehicle information depending on the received vehicle control signal, generating a vehicle information signal having the vehicle information, and again transmitting the generated vehicle information signal to the home server.

2. The system according to claim 1, wherein the telematics terminal comprises:

a sensor unit having a plurality of sensors installed at the external and internal of the vehicle, and receiving measurement values from the sensors and generating an impact sense signal for impact applied to the vehicle and an intrusion sense signal for intrusion of an outsider;

a GPS receiver for receiving satellite position confirmation signals from a plurality of artificial satellites;

a vehicle position confirmation unit for receiving the satellite position confirmation signals from the GPS receiver, calculating a vehicle position coordinate value from the received signals, mapping the coordinate value to map data of a storage unit, and generating current vehicle position information;

a camera driving unit for controlling operations of a plurality of digital cameras installed at the external and internal of the vehicle, receiving image signals from the digital cameras, and generating vehicle periphery image information;

a vehicle interface unit connected with a vehicle network system or a vehicle controller, and receiving vehicle state information or transmitting vehicle control information;

the storage unit for temporarily or lastingly storing a variety of control programs for activating the telematics terminal, the map data, the vehicle position information, the vehicle state information, vehicle image information;

a wireless communication unit connected with the home server through the Internet network or the mobile communication network, and receiving the vehicle control signal from the home server, and transmitting a vehicle position information signal, a vehicle state information signal, and a vehicle image information signal to the home server;

an image processor for displaying the vehicle position information, the vehicle state information, and the vehicle image information through a liquid crystal display; and

a controller for performing a general control of the telematics terminal.

3. The system according to claim 2, wherein the sensor unit has an impact sensor for sensing impact applied to the vehicle from the exterior.

4. The system according to claim 2, wherein the sensor unit has an infrared human-body sensor for sensing outsider'"'"'s approach or intrusion to the vehicle.

5. The system according to claim 2, wherein the vehicle interface unit is connected with a CAN (car area network) taking charge of a general power train of the vehicle, and a MOST (media oriented system transport) for controlling all vehicle multimedia-related systems and controlling image and sound reproduced.

6. The system according to claim 2, wherein the vehicle interface unit is directly connected with the vehicle controller such as an ECU (electronic control unit) and a TCU (transmission control unit) of the vehicle, and is constructed such that the controller can diagnose or control vehicle states of a variety of multimedia equipments, a car door, a trunk, a hood, and a window.

7. The system according to claim 1, wherein the home server further comprises map data, and receives the vehicle position information from the telematics terminal, maps the received vehicle position information to the map data, and displays the mapped vehicle position information to the user.

8. The system according to claim 1, wherein the vehicle information signal comprises at least one of vehicle periphery image information, video communication image information, vehicle state information, and vehicle position information.

9. The system according to claim 1, wherein the vehicle control signal comprises at least one control command of a camera control command, a vehicle remote diagnosis command, a vehicle position confirmation command, and a video communication command.

10. A control method of a telematics system using a home network system that has a home server, a home network center, a telematics service center, and a telematics terminal, the method comprising the steps of:

upon reception of a user'"'"'s request for a vehicle control service, in the home server, generating and transmitting a vehicle control signal;

in the home network center, receiving the vehicle control signal, and transmitting the received vehicle control signal to the telematics service center through an Internet network;

in the telematics service center, receiving the vehicle control signal from the home network center, and transmitting the vehicle control signal to the telematics terminal through a mobile communication network;

in the telematics terminal, receiving the vehicle control signal, executing a control command of the home server, generating a vehicle information signal corresponding to the vehicle control signal, and transmitting the generated vehicle information signal to the telematics service center through the mobile communication network;

upon reception of the vehicle information signal in response to the vehicle control signal, in the telematics service center, transmitting the vehicle information signal to the home network center through the Internet network;

upon reception of vehicle information signal in response to the vehicle control signal, in the home network center, transmitting the vehicle information signal to the home server; and

upon reception of the vehicle information signal in response to the vehicle control signal, in the home server, informing the user.

11. The method according to claim 10, wherein the telematics service center stores an authentication code of the home server user and a registration number of the telematics terminal, and upon reception of the vehicle control signal, requests for authentication of the home server, which transmits the vehicle control signal through the home network center, and upon reception of an authentication code in response to an authentication request, compares the received authentication code with the previously stored authentication code, and performs the authentication.
