摘要
为加深理解并提高汽车电子电器部件的功能安全,介绍了功能安全的概念以及电子电器部件安全性的开发过程。分析了汽车安全完整性等级(ASIL等级)评估分级,并通过实例进一步解释了功能安全等级的划分标准。基于ISO 26262标准,提出了一个新的汽车功能安全设计方案,并给出了每一个设计环节的注意事项和要求,为汽车电子电器部件功能安全设计开发者提供参考。
In order to deeply understanding and improve the functional safety of automotive electronic and electrical components,the concept of functional safety and the development process of the safety of electronic and electrical components were introduced.The assessment classification of ASIL level was analyzed,and the classification standard of functional safety level was further explained through an example.Based on ISO 26262 standard,a new automotive functional safety design scheme was proposed,and the notes and requirements of each design link were given,which provided a reference for the developers of functional safety design of automotive electronic and electrical components.
