Recently, IT-centered convergence between different industries has undergone rapid expansion, accompanied by major advances in u-IT development and digital convergence. Notably, in the automotive-IT convergence sector, automotive sensors and electronic devices interact closely and intelligently with each other, thereby increasing driver safety and convenience and creating the optimal driving environment. This has led to the generation of value-added for the future-oriented automotive industry. Sensing technologies - which are used to monitor traffic situations and transmit correct information (or warnings) on the road traffic situation to car drivers, and to provide accurate information to road traffic controllers - represent both the birth of high-safety, intelligent automotive technologies and the key to automotive manufacturing. In view of these developments, this paper examines the characteristics and structure of the automotive sensor industry, and outlines the policy implications for the automotive sensor industry with regard to the development of the automotive-IT convergence industry.

블루투스란 근거리에 놓여 있는 컴퓨터와 이동단말기 가전제품 등을 무선으로 연결하여 쌍방향으로 실시간 통신을 가능하게 해주는 규격을 말하거나 그 규격에 맞는 제품을 이르는 말이다. 가정 및 사무실에서 사용되는 모든 정보기기에 장착되는 것을 목표로 무선망을 구성하여 어떠한 유/무선망과도 연동할 수 있게 한다. 따라서, 블루투스를 이용한 무선 네트워크가 완성되면 모든 정보기기간의 자유로운 데이터 교환이 이루어지며, 인터넷 브리지를 구성하면 현재 광케이블이나 ADSL, 모뎀 등을 통해 데스크탑 컴퓨터에 도달해 있는 인터넷 정보가 비로소 사용자의 손안에까지 도달할 수 있게 된다. 즉, 무선통신의 궁극적인 목표인 언제, 어디서나, 누구나, 어떤 형태의 정보도 교환한다는 목표에 대한 완성으로까지 볼 수 있다. 미국 시장조사 회사 가트너의 "블루투스 시장의 3단계 발전 전망"이라는 보고서에 따르면, 첫 단계에서는 어댑터 카드나 USB 단자 부착 PC, 고기능 휴대폰 등에 채택되고, 두 번째 단계에는 저가의 Mobile 제품, 무선전화, 개인휴대단말기, 가정용 네트워킹기기, 자동차 등으로 블루투스 탑재기기가 크게 증가할 것이고, 세 번째 단계에는 거의 모든 휴대기기에 채택되어 시장규모가 확대될 것으로 전망하고 있다. 블루투스는 현재 휴대폰, 노트북 컴퓨터, 디지털카메라, 휴대 게임기 등 휴대기기 제조업체는 물론 자동차 제조업체 등 전자, 정보홍신 이외 기업의 지지도 받고 있다.

Drivers check always vehicle state for own safety and is necessary to understand about vehicle state. If driver know vehicle state, because driver request vehicle state at vehicle specialty company, driver pay a lot of money and waste a lot of time. Now, drivers have checked vehicle state by using variety features of smart phone due to progress of IT(Information Technology). but existing smartphone vehicle diagnostic system learned professional knowledge of vehicle and know vehicle state. drives not need vehicle diagnostic. to overcome these disadvantages, there use easily drivers by using smartphone and request system to know own all vehicle state. In this paper, there implement vehicle diagnostic system with smartphone based on android OS to use easily this system and know check information of vehicle supplies replacement cycles, vehicle internal problems, Eco driving by using OBD-II data to receive by OBD-II Protocol convert Bluetooth connector.

This paper discusses the trajectory tracking system of unmanned ground vehicles based on predictive control. Because the unmanned ground vehicles can not satisfactorily complete the path tracking task, highly efficient and stable trajectory control system is necessary for unmanned ground vehicle to be realized intelligent and practical. According to the characteristics of unmanned vehicle, this paper built the kinematics tracking models firstly. Then studied algorithm solution with the tools of the optimal stability analysis method and proposed a tracking control method based on the model predictive control. The controller used a kinematics-based prediction model to calculate the predictive error. This controller helps the unmanned vehicle drive along the target trajectory quickly and accurately. The designed control strategy has the true robustness, simplicity as well as generality for kinematics model of the unmanned vehicle. Furthermore, the computer Simulink/Carsim results verified the validity of the proposed control method.
