Recently, devices such as smartphone and vehicle blackbox and EDR(Evern Data Recorder knowed automotive real-time control and driving data to use OBD-2(in-vehicle network). when devices receive vehicle driving data, communication way use each Wifi, Bluetooth. but if user and driver change device to use OBD-2 connect, the device differ communication network way. and driver buy and change OBD-2 connect. In this paper, to remedy one's shortcomings, there integrate Bluetooth and Wifi network module and design integrability hardware as any another device know vehicle real-time control and driving data with one integrability connect.

This paper develops an OBD Diagnostic Program (Program) using Visual Studio (C#), which was used to diagnosis malfunction information from OBD-II system vehicles. We accomplished this using the Program, Diagnostic tests, Board (STN1110), FTDI Basic Cable, Mini USB Cable, OBD Data Cable, and both hybrid and regular vehicles. The Program tests real-time data output, DTC output, sensor value output, engine RPM, waveform data, OBD type check, PID inspection, and whole monitoring. We found vehicles used in this research had 19 PIDs, which was within OBD-II regulations. We also gathered data on control and diagnostic code regulated by OBD-II system, such as, sensor output value, engine RPM, DTC output, each PID analytic value, OBD type, fuel mode, and whole monitoring result value. Using the data collected through the Program appropriately can lead to more effective diagnostic practices and contribute to education.

Driver for safety always check the status of their vehicle, and it is essential to understand. When driver know vehicle driving status, there is know vehicle driving status to use vehicle realtime control data by OBD-II of vehicle network and connected OBD-II connector. But, connector to receive OBD-II data differ each communication connection method to connect smart device.(such as smartphone, blackbox, EDR) if vehicle driver change another smart device from smart device(such as android -> iphone, iphone -> android), vehicle driver exist the inconvenience that purchase new OBD-II connector. in this paper, As make up for the fault, there is to implement one OBD-II connector that integrate Bluetooth, Wifi, WCDMA module. as result, anything smart device was notified realtime vehicle control data through implemented one OBD-II connector in this paper

In this paper, In this paper, Smart OBD2 terminal collects OBD2 Data on the vehicle. And it passes through this with SmartPhone Bluetooth. OBD2 system is the system to use a variety of Service using it in SmartPhone. Utilizing NFC to help ordinary people, it can easily use to configure the Bluetooth Pairing. By using the Bluetooth 4.0, it is maximized compatibility of Bluetooth. Furthermore OBD2 terminal is a system to minimize the standby power of the terminal to prevent the discharge of the vehicle up issues. Anyone can develop an OBD2 connection App by providing the interfaces to make DB to develop and understand ODB2 data.

Today, According to it widely used that third generation mobile networks service, WCDMA module development technology and its utilization is expanding increasingly and thus to IT Convergence industries is a trend that a lot of appears. This paper, OBD-II communications to bring a vehicle information use and data to an external server transfer and it was developed that vehicle status monitoring from other external devices can be system. From the various sensors inside a vehicle using the OBD-II connector read the information, after converting the user easier to see, WCDMA module using the car status monitoring system to transfer to an external data server was implemented. Developed to test the performance of the system using virtual's state vehicle simulator, which occurs in the real car that will generate the data. It was sent to the OBD-II connector to be occurred data, vehicle status monitoring system was confirmed that Data was received without error. In addition, When this data using WCDMA transmit data to an external server the same data was confirmed that it was received without error. In the future, this technology using the OBD-II vehicle IT convergence technology can be used in a wide range.

This Paper proposed the prediction method of fuel consumption from vehicle informations through OBD-II Interface. We assumed RPM, TPS had a relationship with fuel consumption. We got the output as fuel-consumption from a vehicle RPM, TPS as input by using polynomial equation. We had modelling as quadric function with OBD-II data and fuel consumption data supported by automotive company in real. In order to verify the effectiveness of proposed method, 5 km real road-test was performed. The results showed that the proposed method can estimate precisely the fuel consumption from vehicle multi-data.

Lately, becausing Life, property loss from car accident, vehicles have been used vehicle blackbox like blackbox by airplane. when the accident happened, existing car blackbox that was stored external image or video of vehicle don't know the vehicle's driving conditions. For knowing vehicle's driving conditions, vehicle is loaded sensors for Variety of measurement and control. the sensors is controlled by ECU(Electronic Control Unit) and all vehicles is used Mandatory OBD2(On-board diagnostics) protocol for communication between ECUs since 2006. Using ODB2 protocol, driver use blackbox data by various driving data to occur vehicle' ECU and can be obtained more definitive information. In this paper, there implement smart blackbox system to use exact vehicle's data using OBD2 protocol rather than blackbox to store external image or video.

Recently, wireless network services are widely used, depending on the development of wireless network module technologies and the utilization gradually expanded, and thus is a trend that appears a lot of IT convergence industries. For this study, the OBD-II communication to Import your vehicle information, and other external devices in high-speed driving condition of the vehicle to verify the information system was developed to transfer data to an external server. From various sensors inside the vehicle using the OBD-II connector easily convert all users to read the information, then, Sent to the external server using the wireless network module, high-speed vehicle status check system was implemented. It was to test the performance of the system was developed using the actual circuit in a high-speed road racing vehicles. Transfer data generated from high-speed driving vehicles through the OBD-II scanner and check the status of a high-speed vehicle system was confirmed that this data is normally received. In the future, these new cars convergence of IT technology will grow as a new field of research.

Lately, vehicle combined vehicle and IT(Information Technology) for vehicle's safety and convenience. so, vehicles is equipped with many ECU(Electronic control unit). the ECU's transmit data about each electronic control unit with OBD(On-Board Diagnostics) Network and data about each multimedia with MOST(Media Oriented System Transport) Network. In this paper, Supplementing disadvantage of existing blackbox, Using MOST of in-vehicle multimedia network and OBD-II of in-vehicle control network, blackbox system obtain the vehicle's driving state data. so, blackbox system judge vehicle's driving state and provide vehicle's driving state information to driver. Blackbox system implement the features mentioned above. as a result, blackbox is going to be more accurate blackbox system.
