基于PIC的混合动力汽车综合信息显示仪设计

研究设计了一款以HMI串口液晶显示器为终端的基于PIC18F4580单片机以及CAN总线的混合动力汽车综合信息显示仪。该湿示仪具有电池管理系统参数显示，故障诊断显示，车辆上况显示等功能。通过软件实现预置画面与现场实时数据组合显示，并随时根据需要对显示界面进行修改和扩充。实验表明，该综合信息显示仪不仅保证了信息处理显示的实时性，并能够将表征混合动力汽车工作状态的各项数据通过数字界面，动画界面及时清晰的显示出来。

The design of display instrument for hybrid vehicle integrated information based on PIC

In this paper,the hybrid vehicle integrated information display instrument which based on PIC18F4580 and CAN bus is researched and designed with HMI serial LCD display for the terminal.The indicator has parameter display of a battery management system,fault diagnosis show and vehicle condition display etc.Through the software,it can achieve combination display of pre-screen and on-site real-time data and display interface can modify and expand according to needed at any time.Experiments show that the integr...
