摘要
为建立适用于我国交通状况的AEB行人测试场景,参考国际上已有的研究成果,首先采集了上海道路中的典型行人危险工况,并筛选出52例车与行人冲突的工况样本,然后利用聚类分析的多元统计学方法对这些样本进行分析,得到了5类具有典型特征的危险场景;根据这些典型危险场景设计了兼容我国交通工况的AEB行人测试场景,并建立相应的PreScan仿真模型。通过PreScan仿真测试可在未进行实际场地测试前对AEB系统进行初步评价,进而降低开发成本。
To establish AEB （Autonomous Emergency Braking） pedestrian test scenarios suitable for the Chinese traffic conditions, we make reference of some world existing research results, collect some typical pedestrian dangerous cases in Shanghai, and screen out 52 risk cases of car-pedestrian conflicts, then analyze these cases with clustering analysis to obtain five typical categories of dangerous scenarios. According to these typical scenarios, we design test scenarios for AEB pedestrian system compatible with the traffic situations in China and establish corresponding PreScan simulation model. AEB system can be evaluated preliminarily with PreScan simulative test before field test, thus reducing development cost.
