摘　　要：随着人们对汽车安全性、舒适性要求的不断提高,汽车电子控制功能逐渐增多而复杂.针对使用传统单片机控制方法功能单一、灵活性差等缺点,提出了基于S3C2410和嵌入式操作系统Linux的车载信息终端解决方案.通过分析车载终端功能需求,实现了基于CAN(控制器局域网)和SAE J1939协议的汽车信号采集与解析、GPS(全球定位系统)定位信息采集与解析以及GPRS(通用无线分组业务)数据传输等功能模块的软件设计,并基于嵌入式GUI(图形用户界面)Qt/E设计了良好的人机交互界面.该方案功能丰富、操作简便、可移植性好,易于扩展.With people＇s increasing demands for vehicle＇s safety and comfort,the electronic control functions of vehicle are increasing and becoming more and more complex.In order to resolve the poor function and flexibility of traditional methods for vehicle information terminal on a singlechip,a solution for vehicle information terminal based on S3C2410 and embedded Linux was proposed.By analyzing functional acquirements of the system,the software design was achieved for the acquisition and analysis of vehicle＇s information based on controller area net（CAN） and SAE J1939 protocol,the acquisition and analysis of location information based on global position system（GPS）,as well as the data transmission based on general packed radio service（GPRS）,and a friendly man-machine interface based on embedded graph user interface（GUI） Qt/E was supplied.This solution can provide abundant function,easy operation,good portability,and can be improved easily.
