Analysis of FlexRay Network Communication Delay
摘要
Abstract
Along with people's demanding on car's safety having become increasingly improved, and the main car communication network - CAN network can not satisfy the requirement of people in the real -time performance and determinacy,but the FlexRay network which has benefits to time -triggered determinacy and twin channel' s fault -tolerance has call people's attention and gradually becomes the research hotspot. However it still exists some weakness in the communication delay. This paper is aimed at the network communication delay. Communication cycle is divided into static segment and dynamic segment, static section use the way of TDMA (time division multiple access), so we mainly focus on the data frame's transmission delay; Dynamic section adopts the FTDMA (flexible time division multiple access), so the transmission delay and transmitting delay analysis are our point. Finally, we take advantage of the simulation software to verify the calculation, and our goal is to learn the actual communication time.关键词
