In order to carry out the in-depth investigation of traffic accidents of assisted driving vehicles,and restore the oper-ation situation of the functions,control links and control strategies of the assisted driving system during the accident,the sys-tem-theoretic process analysis(STPA)was studied and optimized based on the idea of systems-theoretic accident model and processes(STAMP).Starting from the perspective of comprehensive factors such as human-vehicle-road-environment,a con-trol framework for the comprehensive factors of traffic accidents of assisted driving vehicles was constructed combining with the typical cases of traffic accidents of assisted driving vehicles.The association rules of traffic accidents causation were exca-vated,and the in-depth investigation method and comprehensive factors investigation contents for the traffic accidents of assis-ted driving vehicles were established.The results show that the comprehensive factors investigation method for the traffic acci-dents of assisted driving vehicles can realize the correlation analysis of control actions at the driving command level,vehicle control level,vehicle execution level and road environment interference level,and thus determine the correlation list of the traffic accidents causation of assisted driving vehicles.The research results can provide the method support for correlation analysis and cause-chain extraction of traffic accidents causation of assisted driving vehicles,so as to improve the prevention level of road traffic accidents of assisted driving vehicles.
