To address the issue of quantitative data during the concept phase, this paper proposes a quantitative safety goal assessment method based on the ISO 26262 standard. By establishing a mapping model between fault scenario dynamics and injury characteristics, simulations were conducted to quantitatively determine the Severity (S), Controllability (C), and Fault Tolerant Time Interval (FTTI). The results indicate that the FTTI increases with rising time headway but decreases as driver reaction time extends; moreover, high-speed conditions exhibit higher sensitivity to variations in these parameters. Without requiring physical prototypes, this method efficiently generates quantitative metrics through parameter configuration, thereby supporting the precise definition of safety goals in the concept phase.

针对概念阶段功能安全量化数据缺失的问题,基于ISO 26262标准,提出一种安全目标量化评估方法。通过构建故障场景动力学与人身伤害特征的映射模型,利用仿真实现严重度(S)、可控性(C)及故障容错时间间隔(FTTI)的定量计算。结果表明:FTTI随车头时距增大而增加,随驾驶员反应时间延长而缩短,高速工况对上述参数变化更为敏感。该方法仅通过参数配置高效输出量化指标,为概念阶段安全目标的精准制定提供支撑。

针对概念阶段功能安全量化数据缺失的问题,基于ISO 26262标准,提出一种安全目标量化评估方法。通过构建故障场景动力学与人身伤害特征的映射模型,利用仿真实现严重度(S)、可控性(C)及故障容错时间间隔(FTTI)的定量计算。结果表明:FTTI随车头时距增大而增加,随驾驶员反应时间延长而缩短,高速工况对上述参数变化更为敏感。该方法仅通过参数配置高效输出量化指标,为概念阶段安全目标的精准制定提供支撑。

To address the issue of quantitative data during the concept phase, this paper proposes a quantitative safety goal assessment method based on the ISO 26262 standard. By establishing a mapping model between fault scenario dynamics and injury characteristics, simulations were conducted to quantitatively determine the Severity (S), Controllability (C), and Fault Tolerant Time Interval (FTTI). The results indicate that the FTTI increases with rising time headway but decreases as driver reaction time extends; moreover, high-speed conditions exhibit higher sensitivity to variations in these parameters. Without requiring physical prototypes, this method efficiently generates quantitative metrics through parameter configuration, thereby supporting the precise definition of safety goals in the concept phase.
