基于OSEK COM的电控系统通信网络实验研究

Electronic Control System Communication Network Experiment Based on OSEK COM

摘要:

通过将CAN与LIN 总线结合,设计了基于OSEK COM规范的通信网络;首先,设计了OSEK COM 和NM 层,使应用层软件可以独立于底层硬件提供通信服务；接着,建立了CAN-LIN 混合的总线网络结构,并以此为基础设计了软硬件系统,建立了基于CAN2.0A格式的通信协议；最后,文章选取了3个代表性较强的节点组成待测网络,对其控制和通信功能进行了验证。

Abstract:

Based on the requirements of the automotive body accessories electronic control system,through the combination of CAN and LIN bus is designed communications network based on OSEK COM specification.First, the design of the OSEK COM and NM layer,application layer software to provide communications services independently of the underlying hardware;Next, create a hybrid CAN-LIN bus network structure as the basis for the design of the hardware and software systems,based one stablished CAN2.0 A communication protocol format;Finally, the article selected three representative nodes into network for verification of its control and communication functions.
