摘要
研究汽车局域网C A N总线在汽车中的具体应用。针对汽车总线技术网关、节点的开发设计,结合现行汽车厂家提出的实际需求,即不改变原汽车电气系统的结构,从实用性和经济性两方面提出了解决方案。本设计采用飞思卡尔微处理器MC9S08DZ作为网关/节点的核心,除了完成网关的CAN数据发送接收功能,还设计出数据采集系统,能完成数据采集和实时数据的输出驱动等功能。因为所有输入信号都严格执行SAEJ1939规程,这更适应于目前的分块开发方式。
The vehicle LAN CAN bus in automotive applications in particular is studied in this subject.The practical and economic solutions are made for car topics of the bus gateway technology,the development of the node design,combined with the existing car manufacturers put forward by the actual demand,which does not change the original structure of the vehicle electrical system.The present design uses Freescale microprocessors MC9S08DZ as a gateway,the core nodes.In addition to the completion of the CAN gateway to receive data distribution function,the data acquisition system is designed to complete the function of data acquisition and real-time data-driven output function and so on.Because all the input signals are strictly enforced SAEJ1939 a point of order,which is more adapted to the current development of the block the way.
