汽车开放架构标准AUTOSAR为不同的汽车解决方案提供了统一的平台,降低了汽车制造商整合的成本。AUTOSAR平台中的网络管理标准,为汽车车载总线网络管理管理协议的开发提供了标准与规范。本文设计了一套符合AUTOSAR网络管理标准的基于CAN总线网络管理协议。并将其应用于实际的车载网络中,实现了各节点同步休眠与状态检测。经过仿真分析,验证了该协议具有较高的实时性,可以保证车载总线可靠、安全地通信。相较于OSEK网络管理机制AUTOSAR网络管理控制算法简单,软硬件开销小,同时实时性较高,可以满足CAN总线以及FlexRay总线在内的多种车载总线的需求。

AUTOSAR framework is hence proposed to provide an open and unified platform for all automotive solution, aiming to reduce the integration cost and complexity. AUTOASR network management specification provides general requirements on vehicle network activity handing. According to AUTOSAR specification, this paper designs an AUTOSAR compliant CAN-specified network management protocol. And applied to the actual vehicle network, all nodes in this net can synchronization to enter sleep state. By this protocol nodes can detect states of each other. Through simulation analysis, the protocol has high real-time and can ensure the reliable, secure communication. Compared to the OSEK network management this protocol's algorithm is simple. The software and hardware cost is small. At the same time its high real-time performance can meet the requirement of CAN bus and FlexRay bus.
