【摘要】 本文介绍了一种燃料电池电动汽车仪表板总成方案．该系统以S3C44BOX为核心．通过CAN总线接口从整车CAN 网络上获取各个传感器和ECU的信息．经过处理分析后,在大尺寸彩色液晶显示屏上以图形化和文字的方式显示汽车运行状态, 包括时速、转速、以及燃料电池工作状况等信息,还能实现汽车行驶记录仪、GPS定位等附加功能,可以完全取代传统仪表盘。更多还原

【Abstract】 In this paper, an instrument panel system on fuel cell vehicle is presented. The system, which is based on S3C44B0X microprocessor, receives the information of all sensors and the messages of ECUs from the vehicle CAN bus by using CAN interface circuit. The information such as mph, rotate speed and the status of fuel cell is displayed on a large-size LCD device in both characters mode and graphics mode. What’s more, it also supports some additional functions like vehicle running-status recorder and global positioning system. So it can completely replace the traditional instrument panel.更多还原
