Abstract
FlexRay는 차량 내 네트워크(In-Vehicle Network)로 최대 2개의 채널로 각 채널당 최대 10Mbps 전송 속도를 가진다. FlexRay는 TDMA(Time Division Multiple Access)와 FTDMA(Flexible Time division Multiple Access) 방식을 사용하여 효율적으로 데이터를 전송하면서도 실시간 통신을 보장하기 때문에 파워트레인 등 안전성이 필수적인 차량 모듈의 실시간 전자 제어에사용된다. 본 논문에서는 ISO 17458 표준과 FlexRay 컨소시엄 문서를 바탕으로 FlexRay의 프로토콜(Protocol), 시간 계층(TimeHierarchy), 메시지 프레임(Message Frame), 커뮤니케이션 컨트롤러(Communication Controller), 적합성 시험(ConformanceTest)에 대해 자세히 설명한다.
FlexRay is an in-vehicle network with maximum two channels and maximum transmission speed of 10Mbps perchannel. FlexRay exploits TDMA (Time Division Multiple Access) and FTDMA (Flexible Time division MultipleAccess) to ensure real-time communication with efficient transmission, so it is used for real-time electronic controlof safety-critical vehicular modules such as powertrain. This paper explains FlexRay protocol, time hierarchy,message frame, communication controller, and conformance test in detail based on ISO 17458 standard andFlexRay consortium documents.
