基于NAIS的AEB系统路口测试场景研究

为建立适合中国道路的自动紧急制动系统路口测试场景。对国家车辆事故深度调查体系（NAIS）数据进行筛选得到582起路口车-车事故案例，运用聚类方法对事故数据进行分析，并根据事故样本数和事故伤亡程度对聚类结果进行典型参数提取，得到17类典型路口车车事故场景。在典型事故场景的基础上分析并加入2车最高碰撞车速、碰撞角度和碰撞类型3个关键参数，使最终得到的测试场景比已有的研究更能准确地反映实际的事故统计情况。

Test Scenarios of Automatic Emergency Braking System at Intersections Based on NAIS

An intersection test scene of automatic emergency braking systems is established for roads in China. A total of 582 vehicle-to-vehicle accident cases are obtained from the National Automobile Accident In-Depth Investigation System(NAIS). The number of accident samples and the level of accident casualties are used to cluster the accident data and extract typical parameters of the clustered categories. Then 17 typical scenes of vehicle-to-vehicle accidents at intersections are obtained. Based on typical accident scenarios, three key parameters of maximum collision speed, collision angle, and collision type are added so that the final test scenario can reflect the actual accident statistics more accurately than existing studies.
