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.
