CAN 网络的车载控制平台设计

摘要

设计基于 ARM11单片机的触控车载网络控制平台；通过直观、简洁和友好的图形用户界面对车载网络中各个节点设备进行触摸控制，以及对车载网络中 ECU 的动态信息的数字化显示，以此取代传统的机械式按键操作和仪表显示设备，减少了中控平台的空间，提高操作的便利性；设计由串口 RS232连接作为 CAN 网络接口的 PIC33F单片机，可对车门窗、车灯、后视镜、空调、导航等设备进行控制；车载网络控制平台的动态显示则提高了车辆智能性，实现了实时性监测和控制。%The reported design is an on-board control platform which is based on ARM11microcontroller and touch screen technology. By connecting vehicle CAN bus network,ECUs and devices can be accessed or controlled using touch screen interface in an intuitive,simple visual and friendly way.The dynamic information of ECU in vehicle network can be displayed.By taking place of traditional mechanical key-strokes and instrumentation and display device,the size of the control platform is reduced and control operations are easier.The controller can control the equipments such as car doors and windows,headlights,rear view mirror,air conditioning and navigation module.A PIC33F microcontroller is used as port as CAN interface via RS232port.The vehicle information is dynamic display and greatly improves the monito-ring and control of the vehicle in real time.
