摘　　要：对汽车事故数据记录器(Event Data Recorder,EDR)数据规范内容进行概述,对EDR数据准确性验证结果进行了总结,介绍了EDR数据在乘员损伤预测、交通事故重建领域的应用进展,为国内数据规范建立和开展相关应用研究提供参考。研究结果表明,EDR记录的碰撞前速度平均相对误差在4%以内,制动状态会影响记录精度;纵向?V的平均相对误差范围为3.5%~6.6%,横向?V平均相对误差为13.8%;气囊点爆状态和安全带使用状态等信息均非常准确;EDR记录的?V和安全带使用状态是影响乘员损伤预测的重要指标。EDR记录的数据除横向?V误差偏大外其余均比较准确,EDR数据为乘员损伤预测及事故重建研究提供了一种新方法。The paper sumnlarizes the development of EDR data regulation and applications in fbreign countries and provides references to establish data regulation and to carry out applied research in china. The paper presents the contents of EDR data regulation and the results of accuracy validation of＂ EDR data. The applications of EDR data in occupant injury prediction and traffic accident reconstruction are introduced, The results show that the average relative error of＂ pre-crash velocity is within 4%, the average relative error of longitudinal A V is from 3.5% to 6.6% and the average relative error of＂ lateral A V is 13.8%. The infbrmation of airbag and seatbelt status is very accurate and the A V and seat belt status are important indicators for occupant injury prediction. It is concluded that the EDR data are accurate except the average error of lateral A V as the dominant error. The EDR data provides a new method for the study of occupant injury prediction and accident reconstruction..
