Abstract

In this paper, we studied vehicle to vehicle (VTV) communication system using DSRC of 5.8 GHz bands. Nowadays, in the road traffic system is going intelligent and advancing, communication between driving vehicle is very important technology for ITS. We can contrive smoothness and safety traffic flowing by exchanging information about velocity, location, braking and driving condition of nearby vehicles. Therefore, we developed and verified the system which required for the communication among vehicles using DSRC technology of 5.8 GHz band hasa 1 Mbps data rate in the high mobility condition. For this, we developed DSRC modem, data link layer and logic link layer to make it possible that communication between vehicles of perfectly operation, and developed application service program for VTV communication. We performed to communication test in the general road and ascent road. In case of the general mad, obtained VTV communication results are more than number of 17 with in 300 m LOS coverage, and total communication time are $2.34{\sim]18.7$ msec that considered maximum 8-transaction. We blow that obtained results can be used VTV communication or the in areas form the feasibility road test as a function or various conditions. In the future, this system is very useful of advanced safety vehicle (ASV) and super smart vehicle system (SSVS) and so on.

본 논문에서는 5.8 GHz 대역의 근거리전용 무선통신기술(DSRC)을 이용한 차량과 차량간의 무선통신에 관하여 연구하였다 첨단화, 지능화 되고 있는 현재의 도로교통체계에서 주행하는 차량간의 통신은 첨단의 지능형 주행을 위한 중요기술이다. 주행 중에 통신 반경 내에 있는 주변 차량들의 속도, 위치, 제동, 운전 상태에 관한 정보를 교환함으로서 원활하고 안전한 교통흐름을 도모할 수 있다. 따라서 본 연구에서는 고속의 차량 이동 환경에서 1Mbps 급의 대용량 데이터 처리 능력을 갖는 5.8 GHz 대역의 DSRC 기술을 이용하여 LOS (Line Of Sight) 조건에서 사용이 가능한 차량간통신 시스템을 개발하였다. 이를 위하여 완전한 능동형의 차량간통신이 가능하도록 물리계층, 데이터 링크계층과 논리계층 그리고 차량간통신 서비스를 위한 응용계층으로 구분하여 개발하였다. 본 연구를 통하여 ASV (Advanced Safety Vehicle)나 SSVS (Super Smart Vehicle System)의 실현을 위한 차량간 무선통신 기술을 확립하였고 이를 통하여 첨단의 ITS 구현 가능성을 확인할 수 있었다.
