Abstract

Recently, with the interest in the 4th industrial revolution, the demand for autonomous driving technology is increasing. V2X communication technology is a core technology for autonomous vehicles that exchanges information with objects such as vehicles, infrastructure, networks, and pedestrians through wired and wireless networks. In this paper, we present the results of the hybrid V2X communication system, which is a hybrid design of WAVE and LTE, and the coverage test to confirm the performance of the system. Through coverage measurement, we show that the hybrid V2X communication performance is superior to the existing LTE or WAVE single communication system in communication coverage, so it can be effectively applied to autonomous driving services.

최근 4차산업 혁명에 대한 관심과 더불어 자율주행 기술에 대한 요구가 높아지고 있다. V2X (vehicle to everything) 통신기술은 자율주행차량에 있어 핵심기술로서 유무선 망을 통해 차량, 인프라, 네트워크, 보행자 등과 같은 객체들과 정보를 교환하는 기술이다. 본 논문에서는 WAVE (wireless access in vehicular environment)와 LTE (long term evolution)를 복합설계하여 구현한 하이브리드 V2X 통신 시스템의 개발결과와 시스템의 성능을 확인하기 위해 커버리지 테스트를 수행한 결과를 제시한다. 커버리지 측정을 통해 하이브리드 V2X 통신 성능이 기존의 LTE나 WAVE의 단일 통신 시스템보다 통신 커버리지에 있어 우수하여 자율주행서비스에 효율적으로 적용 가능하다는 것을 보인다.
