【Abstract】In order to enhance the eficiencyof the Automatic Emergency Braking System （AEB） test scenarios for passengercars，thisstudyutilizes183highwayaccidentsdatafrom China In-DepthAcident Study（CIDAS）databaseto explore theconstructionof highway-based AEB testing scenarios.Staticanddynamicfactorsare extracted from CIDAS database as clustering variables，anda K-means clustering approach is employed to performa preliminary clasificationof theselectedaccidents.Basedontheclustering results，5representativeaccidenttypes are identified.Basedontheidentified typicalaccidentscenarios，andwithreferencetoexistingevaluationstandards，5highwaytestscenariosforpassengercar AEB systemsare developed.The findingsof thisstudycontribute tothe development andperformance optimizationof AEB system.
