摘　　要：建立智能汽车的预期功能安全(SOTIF)评价体系,进行SOTIF设计是实现智能驾驶汽车规模应用的必由之路。为完善自动紧急制动(AEB)系统的SOTIF理论,实现AEB系统的SOTIF设计,本文采用系统理论过程分析(STPA)的方法对AEB系统控制模块进行安全分析。根据安全分析的结果提出AEB系统控制模块的SOTIF评价指标,并基于CRITIC法和优劣解距离(TOPSIS)法对提出的评价指标进行综合量化评价。进一步地,使用提出的评价方法对某型智能汽车的AEB系统控制模块进行了基于实车试验的SOTIF评价,评价结果验证了所提出的AEB系统控制模块的SOTIF评价方法的合理性和实用性。最后,对评价结果进行分析,并根据提出的SOTIF评价指标给出AEB系统的SOTIF改进建议。The establishment of Safety Of The Intended Functionality(SOTIF)evaluation system and SOTIF design are the only way for wide application of the intelligent vehicles.To improve the SOTIF theory and realize the SOTIF design of Autonomous Emergency Braking System(AEBS),safety analysis of the control module of AEBS is conducted by using the method of System Theoretic Process Analysis(STPA)in this paper.Based on the results of the safety analysis,SOTIF evaluation indices of the control module of AEBS are proposed,which are then comprehensively quantified using the CRITIC method and TOPSIS method.In addition,the proposed evaluation methods are used to conduct a SOTIF evaluation of the AEBS control module in a prototype of intelligent vehicle based on real vehicle tests,and the rationality and practicability of the proposed SOTIF evaluation method for the control module of AEBS are verified by the evaluation results.Finally,the evaluation results are analyzed,and further the SOTIF improvement suggestion for the control module of AEBS is put forward according to the proposed SOTIF evaluation indices.
