Driving scenario data is the data basis for the development of autonomous driving functions,and the dangerous scenarios based on real traffic accidents on Chinese roads are an important part of the scenario database and a necessary condition for the verification of vehicle development functions.The basic conditions for the admission of autonomous driving functions are the basic conditions for the safe passage of dangerous scenarios and the successful avoidance of accidents or the minimization of damage caused by accidents,and the research and development of accident simulation scenarios is an important part of the early functional verification of intelligent networked vehicles.
