Research on the evaluation method of AEB car-to-car test based on traffic accident data in China

As the main component function of ADAS, the assessment methods on AEB have been guiding OEMs to make functional improvements and the active safety capability of the vehicle has been increasing. By screening the car-to-car accident data in China, key factors such as offset situation, vehicle speed distribution and accident severity have been analyzed and counted. Subsequently, the corresponding weights have been reasonably determined. Finally, a scientific AEB car-to-car assessment method has been obtained, forming the relevant part of the C-NCAP 2021 Edition. The test method proposed in this paper can objectively and reasonably evaluate the AEB performance of vehicles.
