基于系统理论过程分析(system theory process analysis,STPA)提出了一种在汽车驾驶辅助系统中进行安全性分析的方法.该方法应用在紧急刹车辅助系统的原型开发阶段,通过安全分析得到系统的4个不安全控制行为(UCA).针对不安全控制行为,分析得到不安全控制行为的6个致因场景,导出5个安全需求.
Application of STPA Method in Safety Analysis of Emergency Brake Assist System
Based on system theory process analysis(STPA),a method of safety analysis in automotive driver assistance system is proposed.This method is used in the prototyping phase of emergency brake assist systems,Through safety analysis,four unsafe control actions(UCA)of the system are obtained.Aiming at unsafe control actions,six reasons for unsafe control actions are obtained and five security requirements are exported.
