文章基于ISO 26262 第三部分概念阶段的要求，结合SA E J2980 的补充，详细介绍了功能安全概念阶段相关项定义、危害分析与风险评估和功能安全概念开发三大活动的开发流程及方法。以自适应巡航功能为例，以功能激活这一子功能为落点，阐述了主机厂在功能安全概念阶段的分析与设计过程，包括相关性定义应包含的内容、HARA分析方法、ASIL等级的确定、安全目标及功能安全要求的导出等，对其他智能驾驶系统功能的功能安全开发具有一定的指导作用。
Analysis of Functional Safety Concept Design by Adaptive Cruise Control
Based on the requirements of ISO 26262 part 3:concept phase and the supplement of SAE J2980,this paper introduces in detail the development process and methods of the three activities of functional safety concept:item definition,hazard analysis&risk assessment and functional safety concept.Taking adaptive cruise control as an example and function activation as a sub-function,this paper expounds the analysis and design process of OEM in the functional safety concept stage,including the content of item definition,the methods of HARA,determination of ASIL capability,derivation of safety goals and functional safety requirements,etc.It has a guiding effect on the functional safety concept design of other intelligent driving functions.
