摘　　要：介绍汽车CAN总线节点设计,提出一种基于微控制器的总线节点解决方案。选择MC9S12DG128作为节点控制器,选用PCA82C250收发器;软件设计编程实现对CAN总线节点数据通信,即完成CAN控制器初始化、报文发送和报文接收,同时简要描述CAN总线协议2.0报文格式。最后以一种CAN信号模拟装置的CAN节点模块为设计实例,进一步表述汽车CAN总线模块设计,指出CAN节点模块设计方法可行且相对硬件电路简单。The node design based on automobile CAN bus system is introduced and a bus node solution based on microcontoller is given. MC9S12DG128 is chosen as node controller and PCA82C250 as transceiver. CAN bus node data communicaions is realized by software design program, which completes CAN bus cotroller initialization, and message sending and receiving. At the same time, 2. 0 message format of CAN bus protocol is briefly described in the paper. Finally, the further expression about module design of automobile CAN bus is given through choosing a kind of CAN node module of CAN singnal simulator equipment as a design example. Therefore, the design method about CAN node module is feasible and corresponding hardware circuits are simple.
