Market Focus: Benefits of Functional Safety in Automotive Applications
Human safety is an increasingly hot topic in the automotive world. As autonomy increases and demands for every-improving safety features increase, so do discussions about keeping people safe in their electric or internal combustion vehicle. Functional safety is the engineering discipline which takes a system view and labors to eliminate systemic faults and mitigate random faults in automobiles. Top-down, hierarchical decomposition is conducted to assure appropriate safety measures are put in place to eliminate unintended consequences that can lead to injury or death. Further, the added discipline of functional safety drives additional system improvements and features, as well as enhancing product quality. This session will describe the intention and approach of functional safety, and discuss the benefits brought about by this discipline.
Technical Focus: Functional Safety Practical Concerns
The international standard for functional safety in road vehicles, ISO 26262, defines “functional safety” as the “absence of unreasonable risk due to hazards caused by malfunctioning behavior of electrical and/or electronic systems”. Achieving functional safety requires first identifying what failures might lead to an unsafe condition, and then implementing “safety mechanisms” to detect when such faults occur and prevent them from becoming safety hazards. In this session we’ll look at some of the ways functional safety is achieved in semiconductor devices, and understand key terms like SEooC, ASIL, and Quantitative Metrics & FIT. We’ll explore how these items contribute to the “Safety Manual”.
