摘要

车载通信网络管理(NM)系统的性能直接影响到汽车电子网络通信安全.对OSEK NM中逻辑环机制实际运行状态进行建模

建立各工作状态间转换模型;引入NM诱导报文和逻辑环不稳定时间

定量分析OSEK NM逻辑环不稳定工作状态

推导出度量逻辑环工作性能的计算公式;提出一种支持第二直接后继的逻辑环建环机制

给出该机制下逻辑环的工作性能.实验结果表明:相对于OSEK NM

支持第二直接后继的建环机制不仅能够提高车载NM的实时性

而且能有效降低NM对用户报文传输的不良影响.

Abstract

The performance of vehicular network management has a great effect on communication safety between automotive electronic systems.The practical working states of OSEK NM logical ring are modeled and a transition model among working states is established.The definitions of NM induced message and logical ring instable time are introduced

and the equations to evaluate NM performance are derived after the instable state is analyzed quantitatively.A scheme of building ring with second immediate successor is presented and its performance is also analyzed.Experiments show that compared to OSEK NM

the scheme in this paper can effectively improve real time of vehicular NM and reduce its bad interruption on the user message transmission.
