X-By-Wire 시스템을 위한 통신 프로토콜의 성능 평가

Today, many protocols have been developed to satisfy various requirements for automobile application. Especially, the X-By-Wire system is issued in automobile company, and protocols such as TTP, TTCAN, and Flex Ray have been developed by many automobile companies. However, because any protocol is not dominant in the market yet, it is very difficult to choice appropriate protocol for X-By-Wire system. Hence, this paper presents the performance evaluation of CAN and TTP via discrete event simulation to compare features of X-By-Wire protocols. Through numerous simulation experiments, several important performance indices such as the transmission failure rate, average system delay (data latency), and maximum system delay have been evaluated.
