Abstract:

In order to clarify the main safety risk types of Chinese passenger car occupants at present, and to promote the establishment of automobile safety evaluation standards and regulatory systems that are more in line with China’s actual road environment and traffic accident characteristics, the accident scenarios causing the death of passenger car occupants were classified and counted based on China in-depth accident study (CADIS) data by using basic classification variables. The results show that 6 high-risk conflict scenarios suitable for evaluating the active safety performance and 7 high-risk collision scenarios applicable to the evaluation of passive safety performance are extracted with the new classification method for accident scenarios. Meanwhile compared with the current test scenarios of Euro NCAP and C-NCAP, it is found that the scenarios such as passenger cars’ drilling into trucks, drivers’ abnormal physical conditions, frontal impact on posts and guardrail ends cannot be covered, showing that institutions like C-NCAP, China Automobile Standardization Commission, road traffic management departments need to establish vehicle safety evaluation standards and legal systems that are more consistent with China’s actual road environment and traffic accident characteristics through further in-depth research and quantitative analysis of relevant scenarios. At the same time, it also points out some related topics that need to be studied as soon as possible.
