In order to enhance the efficiency of the Automatic Emergency Braking System (AEB) test scenarios for passenger cars, this study utilizes 183 highway accidents data from China In-Depth Accident Study (CIDAS) database to explore the construction of highway-based AEB testing scenarios. Static and dynamic factors are extracted from CIDAS database as clustering variables, and a K-means clustering approach is employed to perform a preliminary classification of the selected accidents. Based on the clustering results, 5 representative accident types are identified. Based on the identified typical accident scenarios, and with reference to existing evaluation standards, 5 highway test scenarios for passenger car AEB systems are developed. The findings of this study contribute to the development and performance optimization of AEB system.
