1.标准要求

5.4.11 The development of the decomposed elements at the system level and at the software level shall be performed, as a minimum, in accordance with the ASIL requirements (after decomposition) of ISO 26262-4 and ISO 26262-6. The development of the decomposed elements at the hardware level shall be performed, as a minimum, in accordance with the ASIL requirements (after decomposition) of ISO 26262-5, except for the evaluation of the hardware architectural metrics and the evaluation of safety goal violations due to random hardware failures (see 5.4.5).

5.4.11 应至少按照GB/T34590.4—2022和GB/T34590.6—2022中(分解后的)ASIL等级要求,在系统层面和软件层面开发分解后的要素。应至少按照GB/T34590.5—2022中(分解后的)ASIL等级要求,在硬件层面开发分解后的要素,但硬件架构度量的评估和因随机硬件失效导致违背安全目标的评估除外(见5.4.5)。
