Development of Intelligent Information Display System for Hybrid Vehicle

设计了混合动力汽车智能信息显示系统,该系统以32位嵌入式系统为硬件平台,定制了WINCE6.0操作系统,采用EVC应用面向对象的方法进行嵌入式应用程序设计。系统实现了CAN通信、信息显示、数据保存、故障在线诊断、数据无线传送等功能,解决了高频电路设计、WINCE系统定制、程序实时性保证、程序内存控制、无线通信等技术难题。实车测试表明,该系统运行效果良好,实现了全部设计功能。

The intelligent information display system for a hybrid vehicle was designed in this paper, and this system took the 32-bit embedded system as a hardware platform,customized a WinCE6.0 operating system and used EVC as the tool to design the program. The functions of CAN communication, information display,data saving,OBD,data wireless communication ete were realized,and the technical difficuhiess such as high-frequency circuit desigu,WINCE system customization,program real-time guarantee,program inner memory control and wireless communication ete were resolved. The on-board test indicated that this system operated well and realized the whole design functions.
