Adaptation of STPA method on the functional safety development of autonomous vehicle

Abstract:
As the general trend of the development of autonomous technology in the future, automatic driving has become one of the hotspots that cannot be ignored in the industry. Due to the shortcomings of traditional hazard analysis methods, they cannot be well adapted to the modern automobile safety analysis with intensive software and complicated electronic control units. Under the framework of the current functional safety standard, STPA method is applied to the hazard analysis in the development of its earlier concept stage, and the cause scenarios is identified based on unsafe control behavior, so as to obtain more complete functional safety requirements.
