摘要
在自主设计的旋转变压器解码系统的基础上,根据功能安全标准(ISO26262)中硬件阶段的功能安全研究规范展开了对所设计的解码系统的硬件阶段的功能安全研究。研究过程严格按照功能安全标准的硬件阶段的研究规范(ISO26262-5)执行,同时参考了其他国外的硬件评价指标。通过最后的硬件阶段功能安全研究结果表明,所设计的解码系统能够满足硬件安全需求,并且硬件架构度量评估结果符合相应的汽车完全安全等级(ASIL)的需求。
On the basis of the self-designed resolver decoding system,according to the functional safety research specifica-tion in the hardware stage of the functional safety standard(ISO26262),the functional safety research in the hardware stage of the designed decoding system is carried out.The research process was carried out in strict accordance with the hardware stage research specification(ISO26262-5)of the functional safety standard,and other foreign hardware evaluation indexes were also referred.The results of functional safety research in the final hardware stage show that the designed decoding system can meet the requirements of hardware safety request,and the hardware architecture measurement evaluation results meet the requirements of the corresponding automotive complete safety level(ASIL).
