Abstract: This paper introduces an application of CAN of fuel cell vehicles. A new CAN application layer is designed for the control network of fuel cell vehicles. Messages in the network are classified and the priorities of messages are assigned according to their classes with the redefined ID field of CAN2.0. The protocol includes specific destination communications and broadcast communications. The hardware and software of CAN is discussed emphatically, which is designed based on P89C58×2FN of Philips.

Key words: fuel cell vehicle, controller area network(CAN), protocol

摘要: 介绍了CAN总线在燃料电池轿车中的具体应用,通过研究CAN协议的原理及应用技术,根据燃料电池轿车辅助系统控制策略的要求,设计了新的CAN线应用层协议。该协议对网络信息进行了分类及合理的优先权分配,而且在CAN2.0的基础上重新定义了标识符,实现了广播式和点对点的通信。讨论了以Philips公司8位单片机P89C58×2FN为核心的CAN总线智能节点的软硬件实现。
