摘要
OSEK网络管理(NM)机制保障了汽车网络安全可靠的运行,同时也降低了有关网络实时性,如何引入OSEK NM机制并提高汽车网络的实时性至关重要。从提高汽车网络实时性出发,通过分析有关网络的实时性,改进OSEK NM中节点加入退出机制,并通过软件仿真证明了改进后的机制提高了汽车网络的实时性。
OSEK network management (NM) mechanism ensures the vehicle network to work safety and reliability, meanwhile reduces the real-time of network. How to improve the real-time of the vehicle network willl the introduction of OSEK NM is very important. In order to improve the vehicle network real-time, this paper perfect the OSEK NM mecha- nism of nodes participate and drop out by the analysis of relewmt network real-time pertimnance, and the improved vehicle network real-time of the improved mechanism can be proved by software simulation.
