基于EDR数据的无轮胎印迹交通事故重建方法研究

交通事故重建是交通事故分析、交通事故司法鉴定、交通事故深度调查的重要手段。传统的交通事故重建方法对现场轮胎印迹及车体痕迹依赖程度较高,随着汽车主动安全技术的发展,交通事故中的轮胎印迹越来越少,交通事故重建的技术难度逐渐增大。与此同时汽车ECU数据处理能力不断提高,以EDR为代表的数据记录装置为交通事故重建提供了新途径。

Traffic accident reconstruction is an important means for traffic accident analysis,judicial expertise and in-depth investigation.The traditional method of traffic accident reconstruction highly depends on on-scene tire marks on road surface and scrap marks on the vehicle.With the development of automotive and active safety protection technologies,less and less tire marks are left on the accident scene,which makes the technical difculty of traffic accident reconstruction increase gradually.However,with the improverment of ECU data processing capability,the data recorder device on the vehicle represented by EDR is now providing a new way for traffic accident reconstruction.
