标准摘要
[中文适用范围]: 本 SAE 推荐实践介绍了确定汽车运动控制电气和电子 (E/E) 系统的汽车安全完整性等级 (ASIL) 的方法和示例结果。 ISO 26262-3:2011 [1]@ 要求进行 ASIL 确定活动,并且本文的过程和结果与 ISO 26262:2011 [1] 一致。本文档的技术重点是车辆运动控制系统。仅限于重量不超过 3.5 吨的乘用车。此外,本建议实践的范围仅限于与运动控制系统相关的碰撞相关危险。建议的做法侧重于运动控制系统,因为与非运动控制系统可能产生的危险相比,它们可能产生的危险通常具有更高的 ASIL 等级@。因此,功能安全委员会决定给予运动控制系统更高的优先级,并在 SAE J2980 推荐实践中专门关注它们。 ISO 26262:2011 [1] 的范围比 SAE J2980@ 更广泛,涵盖其他功能和事故(不仅仅是 SAE J2980 中的运动控制或碰撞)。目的 本 SAE 建议实践旨在为危险事件@的识别和分类提供指导,这些事件是根据 ISO 26262:2011 [1]@ 利用 ISO 26262:2011 [1] 危害分析和风险评估 (HARA) 在车辆级别定义的方法。本 SAE 推荐实践旨在作为标准实践的指南,并且可能会发生变化,以跟上经验和技术进步的步伐。它无意于替代 ISO 26262:2011 [1] 的概念阶段活动。本文档中包含的所有示例和样本旨在帮助读者理解本文档@中提供的指导,而不是详尽或完整的参考。因此@它们不能替代读者尝试应用 ISO 26262:2011 [1] 的特定项目的相应分析。 [外文原描述]: This SAE Recommended Practice presents a method and example results for determining the Automotive Safety Integrity Level (ASIL) for automotive motion control electrical and/or electronic (E/E) systems. The ASIL determination activity is required by ISO 26262-3, and it is intended that the process and results herein are consistent with ISO 26262. The technical focus of this document is on vehicle motion control systems. The scope of this SAE Recommended Practice is limited to collision-related hazards associated with motion control systems. This SAE Recommended Practice focuses on motion control systems since the hazards they can create generally have higher ASIL ratings, as compared to the hazards non-motion control systems can create. Because of this, the Functional Safety Committee decided to give motion control systems a higher priority and focus exclusively on them in this SAE Recommended Practice. ISO 26262 has a wider scope than SAE J2980, covering other functions and accidents (not just motion control or collisions as in SAE J2980).
