摘　　要：本文首先简要介绍了CAN总线的技术特点,同时把针对电动汽车的特点,建立车身网络的拓扑结构。详细的介绍了CAN通讯协议准的拓扑结,制定了CAN总线应用层协议的通讯报文形式。CAN总线通讯的硬件采用MC9S12DP51216单片机。应用LABVIEW软件,定义各个控制量的函数结构,并且建立不同模块的程序框图。为了检验车身网络的通讯数据,建立数据控制面板和显示面板,对通讯数据进行检测。This paper first introduce the structure of the car networking is buih technical features of CAN bus. In cognizance of specialty of electric vehicle, the topology The CAN bus communication protocol was explained and the form of the communication message is established on application layer. MC9S12DP51216 is adopted for use in the CAN bus communication. LABVIEW is used to define the function structure of every variable and to build program layout for different modules. To check the communication data of car networking, the control panel and display panel is formed.
