The present invention relates to a vehicular gateway system for a network-based interface, and more particularly, to a vehicular gateway capable of multi-interface and interworking with home networking through a vehicular gateway.

1 is a block diagram of a conventional GPS (Global Positioning System) navigation apparatus. As shown in FIG. 1, the conventional GPS navigation apparatus includes an antenna 5 for receiving a GPS signal and an absolute position based on longitude and latitude by simultaneously receiving radio waves from a plurality of GPS satellites through the GPS antenna 5. GPS receiver 10 for obtaining a signal, an RS-232C level converter 20 for converting a serial output of a CMOS or TTL level output from the GPS receiver 10 to an RS-232C level for serial communication with a PC and the like. And a regulator 15 for supplying the voltage specified in the GPS receiver 10 and other circuits from the cigar jack 25 or an external power source.

The conventional navigation device as described above is connected to a notebook or a pocket PC 30 and an RS-232C cable 35 so as to display the latitude, longitude and speed, altitude, satellite information, etc., in which a car or a ship is currently located. It can be displayed on application software such as navigation software installed in 30, or a navigation function can be realized.

However, since the conventional GPS navigation apparatus does not have a power pin on the RS-232C connector itself, the GPS navigation apparatus requires a separate power supply from the PS / 2 port to which the cigar jack 25 or the keyboard is connected. Or, since many models without the RS-232C connection terminal, which is a serial communication port, are used in the Pocket PC 30, there is a problem that is incompatible with the conventional GPS navigation apparatus.

The server is provided in the service center 75 to provide additional services such as remote vehicle diagnosis, traffic information service, point of interest (POI) service, and emergency emergency service to various vehicles. The communication with 75 uses packet communication of the wireless network 80 using the CDMA 50 network.

However, since the navigation system has to extract the vehicle speed sensor signal, it is difficult to install, and it is possible to receive additional services only through a service center, thereby reducing the generality and paying for the additional services. There was a problem.

3 is a block diagram showing a conventional vehicle interface device. Referring to FIG. 3, a dedicated terminal 85 for short-range bidirectional communication is installed in the vehicle 90, and a vehicle signal is interfaced to the dedicated terminal 85 to lock the door lock using the remote controller 95 at a short distance. Remote control such as on / off, start control, discharge prevention and trunk, and vehicle status can be identified.
