摘要： 两轮车事故是我国道路一种重要的交通事故类型,但我国在自动紧急制动(AEB)系统研究中还缺乏合适的两轮车测试场景。据此,本文中参考国际上已有的研究成果,建立适用于我国道路交通环境的AEB系统两轮车测试场景。首先,对419起汽车与两轮车碰撞事故案例进行了聚类分析,获得了11类典型的汽车与两轮车碰撞事故场景;接着,根据11类场景在不同参数特征下的事故伤亡程度和事故样本数,准确地获得了各类场景中两轮车运动状态、汽车车速和两轮车车速的详细参数特征;最后,设计了汽车在照明良好的情况下直行通过路口的主要测试场景,通过改变主要测试场景得到了其它5类次要测试场景,且因而最终获得汽车与3种不同两轮车类型(电动两轮车、摩托车和自行车)碰撞下6类AEB系统两轮车测试场景的具体参数特征。本研究结果可为研究我国AEB系统两轮车测试提供参考依据。

Abstract: Two-wheeler accident is an important type of road traffic accidents in China. However, China lacks suitable two-wheeler test scenes in automatic emergency braking (AEB) system research. In view of this, two-wheeler test scenes for AEB system adapted to road traffic environment in China are established in this paper by taking references from existing research outcomes in the world. Firstly, a cluster analysis on 419 cases of car-to-two-wheeler crash accidents is conducted, and 11 typical types of car-to-two-wheeler crash accident scenes are obtained. Then, according to the severity of accident casualty and the number of accident samples under different parameter features of 11 types of scenes, the detailed parameter features of two-wheeler motion states, the speed of car and two-wheelers in all types of scenes are accurately obtained. Finally, a main test scene with the car straightly passing through intersection under good lighting condition is designed, and through the variation of the main test scene, another 5 types of secondary test scenes are obtained, and hence in the end, the specific parameter features of altogether 6 types of two-wheeler test scenes (main test scene plus 5 secondary test scenes) for AEB system under the conditions of car crashing with three different two-wheelers (two-wheeled electric vehicle, motorcycle and bicycle) are given. The findings of this study can provide a reference basis for the research of two-wheeler test for AEB system in China.
