    ISO 26262-11: Exposure, Severity and Controllability

    In semiconductor functional safety, understanding risk is everything. The ISO 26262 standard defines a systematic approach to safety. Chapter eleven focuses on ASIL, the Automotive Safety Integrity Level, which is determined by three critical factors: Exposure, Severity, and Controllability. Exposure measures how often the vehicle operates in a state where a hazard can occur. Part of the Critical Systems Analysis functional-safety series on Semiconductor Functional Safety. In this episode: Welcome to this functional safety micro-lecture.Risk assessment in functional safety rests on three pillars.Exposure ranges from rare to frequent.Severity levels reflect the potential harm to occupants, ranging from no injury through minor injury, serious injury, to fatal injury.Controllability asks: can the driver or occupant control or mitigate the hazard once it occurs? A hazard that the driver can easily prevent or correct is more controllable than one that is sudden and unavoidable.The ASIL levels are determined by combining Exposure, Severity, and Controllability.Reference: ISO 26262:2018 Part 3 (Concept Phase), Clause 6.3.2: Defines Exposure as proportion of time in operational situations where a failure event can lead to harm.
