Abstract

In this paper, we examine Ethernet based vehicle network which is recently emerging technology. Current MOST for entertainment will be soon replaced with the emerging Ethernet based vehicle network. Although legacy standard Ethernet has several advantages it is not suitable for vehicle backbone network without any modification. As a result, many researches are happening on extending and modification of the Ethernet function for realtime and reliability. Time-triggered Ethernet, one of many trials known as AS6802, is investigated on the architecture and functionalities. We design the traffic model on Time-triggered Ethernet and analyse the latency of the network. We also consider the QoS requirement and environment of operating configuration for vehicle network.

본 논문에서는 최근 자동차 산업의 뜨거운 이슈로 부각되고 있는 이더넷 기반 차량 네트워크 기술을 살펴본다. 현재 인포테인먼트에 널리 쓰이는 MOST(Media Oriented Systems Transport)를 차량용 이더넷이 조만간 대치할 것으로 보이고 있다. 하지만 이더넷의 여러 가지 장점에도 불구하고 차량네트워크의 통합 백본으로 쓰기 위해서는 기존 표준 리거시 이더넷으로는 적합치가 않다. 따라서 브로드밴드 멀티미디어 트래픽뿐만 아니라 운전자 지원 및 안전 서비스 영역에서 요구하는 실시간성 및 신뢰성 요구조건에 맞도록 표준 리거시 이더넷을 확장 수정할 필요가 있으며 이를 위한 다양한 시도로써 타임-트리거드 이더넷(Time-triggered Ethernet)으로 알려져 있는 AS6802를 살펴보고, 트래픽 모델 해석적 성능 분석과 최악의 경우 지연시간 분석을 통해 차량네트워크로써 적합한 운용조건과 환경을 고찰한다.
