해당 포스팅은 차량 기능안전 표준인 ISO 26262의 정의된 용어 중 ASIL 에 관한 내용을 정리합니다.

 

Term	Description
automotive safety integrity  level ASIL	one of four levels to specify the item's or element's necessary ISO 26262 requirements and safety measures to apply for avoiding an unreasonable risk, with D representing the most stringent and A the least stringent level Note 1 to entry: QM is not an ASIL.
ASIL capability	capability of the item or element to meet assumed safety requirements assigned with a given ASIL Note 1 to entry: As a part of hardware safety requirements, achievement of the corresponding random hardware target values for fault metrics allocated to the element is included, if needed.
ASIL decomposition	apportioning of redundant safety requirements to elements, with sufficient independence, conducing to the same safety goal, with the objective of reducing the ASIL of the redundant safety requirements that are allocated to the corresponding elements Note 1 to entry: ASIL decomposition is a basis for methods of ASIL tailoring during the design process (defined as requirements decomposition with respect to ASIL tailoring in ISO 26262-9) Note 2 to entry: ASIL decomposition does not apply to random hardware failure requirements per ISO 26262-9 Note 3 to entry: Reducing the ASIL of the redundant safety requirements has some exclusions, e.g. confirmation measures remain at the level of the safety goal.
