摘要
为了实现车载导航仪和发动机ECU(电子控制单元)的通信,提出了一种方案。导航仪的操作系统选用Windows Automotive 5.0,处理器选用S3C244OA;用CAN总线通讯技术建立起汽车发动机ECU与车载导航仪的通讯,以实现数据与指令的高速传递;研制了一个用于连接CAN网络与车载导航仪的接口模块,为此,设计了接口模块的硬件电路,建立了CAN通讯协议并开发了相应的软件,最终实现了在CAN网络上的高速运行。
In order to achieve communication between vehicle navigator and engine ECU （Electronic Control Unit）,a programme is proposed.Operation system of navigator is Windows Automotive 5.0,and its processor is S3C244OA;In order to achieve high- speed transmission of data and instructions,communication technology of CAN bus is used to establish communication between automobile engine ECU and vehicle navigator.An interface module is developed for connecting the vehicle navigator and CAN network.For that,a hardware circuit of interface module is designed.
