摘要
针对汽车事件数据记录系统(EDR)设计了一种基于统一诊断服务(UDS)协议的数据提取方法,使用UDS中常用的读取数据流服务通过OBD口来读取EDR中的事件数据。分析了数据传送过程,并使用C#语言开发了上位机软件,通过通信接口模块可对EDR存储的事件数据进行提取、存储、显示和自动生成报告。
A method of data extraction based on unified diagnostic service(UDS) was designed for vehicle event data recorder(EDR). The service of reading data by identifier in the UDS was used to read the event data of EDR through the OBD interface. The process of data transmitting was analyzed, and PC software was developed using C#. The software can be used to extract, save and display the event data with a communication interface module, it also can generate report with the data.
