摘要
基于Cortex-A8嵌入式开发平台和SAE J1939协议,通过解析CAN总线报文、后台数据处理和前端应用程序开发,设计出了一套车载信息服务系统。经过测试表明,该系统能稳定显示车辆实时运行状况,并能分析和保存故障信息,方便车主的维护和保养;其易操控性和良好的人机交互体验使本系统具有一定的实用价值。
An on-board vehicle information system based on Cortex-AS embedded system and SAE J1939 protocol is de- signed,which consists of CAN-packets of analyze, data processing in the background and front-end applications. Testing results show that the system can display vehicles real-time conditions stably, and it can analyze and save the fault messages which will be used for the vehicle＇ repair and maintenance. Its user interface and easy operation will provide a practical tool for drivers.
