摘要
介绍了基于OSEK/VDX规范的车身CAN网络管理方法,定义了帧的传输类型,对间接网络管理作了深入的研究,并且给出了间接网络管理中监督帧的设计方法及具体实现方式。同时对网络状态作了阐述,完善了网络管理的内容。通过监督帧的设计和网络节点的C MUTE和C ABSENT计数器规则的阐述解决了车身网络管理的关键技术,通过实际应用验证了方法的可靠性。
This paper introduces a CAN-BUS network management method based on OSEK/VDX standard, defines a transmission type of frames investigates the indirect network management in detail, and presents a design method and its realization of supervision frame in direct network management. The CAN- BUS network state is also explained in order to perfect network management. The key technologies of vehicle body CAN network management are solved with the design of supervision frame and the description of C _ MUTE and C _ ABSENT counter rulers. The reliability of the method is demonstrated by its application to practice.
