Multifunctional OBE for its
First Claim
1. OBE (on-board equipment) having a GPS (global positioning system) receiver in an ITS (intelligence transport system) configured with the OBE and RSE (roadside equipment) installed at a roadside, a toll booth or a parking lot for communicating with the OBE mounted on an automobile by transmitting/receiving a wireless signal, or an IR (infrared ray) signal, the OBE comprising:
- an OBE case for housing internal circuits of the OBE;
a GPS receiver for providing a current position of the automobile by receiving navigation data from a GPS satellite through a GPS antenna;
a key input unit for inputting predetermined commands to perform target operations of the OBE;
a card reader for performing an automatic accounting routine according to an ETC (electric toll collection) to pay a toll fee and a parking fee by using financial information stored in a smart card;
a serial communication unit for downloading predetermined data from an external device to update geometric information to providing a navigation service;
a speaker for outputting sound;
a micro amplifying MMIC (monolithic microwave integrated circuit) for modulating data to a wireless signal and transmitting the wireless signal to the RSE through an OBE antenna; and
an integrated microprocessor ASIC (application-specific integrated circuit) for storing predetermined software to perform a DSRC (dedicated short range communication) protocol, storing a geometric information database to provide a navigation service, storing a real-time traffic information database to provide real-time traffic information, providing traffic information through the speaker as voices by using positioning information transferred from the GPS receiver and data transferred from the micro amplifying MMIC, and providing predetermined functions according to an input of the key input unit, wherein main functions of a GPS terminal including an antenna, a coordinate recognizing CPU (central processing unit), and a POI (point of interest) are mounted in the OBE case to commonly use the OBE case, electric power and an indicator, and a voice service is provided through an internal speaker to inform a position of the automobile, to provide an electric toll collection function, and to provide traffic information by interacting with a CPU function of the GPS terminal and a CPU function of the OBE.

Abstract
Multifunctional on-board equipment (OBE) for an automobile is provided. The OBE includes a GPS terminal to commonly use a case, an electric power and an indicator, and provides a voice service through an internal speaker to notice a position of the automobile, to provide an electric toll collection function, and traffic information by interacting a CPU function of a GPS terminal and a CPU function of the OBE. Also, the OBE includes an MP3 player and music selection switches for reproducing and outputting music through an internal speaker or an external speaker connected through an audio output terminal while a user drives the automobile. The OBE includes a microprocessor core with predetermined interface software specially designed in L1, L2 and L7 layers to reduce a size and a manufacturing cost.
