ASIL Accuracy
ASIL accuracy describes the maximum possible deviation of a measurement in a system in which a single point fault occurred before some diagnostic detects this fault. This concept applies to automotive systems designed under the ISO 26262, ISO-26262 methodology for automotive functional safety, which defines Automotive Safety Integrity Level, Automotive Safety Integrity Levels (ASILs) to classify risks. While Accuracy and precision, accuracy refers to a single measurement, ASIL accuracy considers variation in the primary measurement being assessed as well as variation in the diagnostic measurement or measurements used to detect single point faults. How to calculate A conceptually simple implementation incorporates a fully redundant measurement. A fault in the primary measurement can be detected by comparing the primary and diagnostic measurements, and signaling a fault if the difference is outside the expected operating range. If the two measurements are truly independent and u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISO 26262
ISO 26262, titled "Road vehicles – Functional safety", is an international standard for functional safety of electrical and/or electronic systems that are installed in serial production road vehicles (excluding mopeds), defined by the International Organization for Standardization (ISO) in 2011, and revised in 2018. Overview of the Standard Functional safety features form an integral part of each automotive product development phase, ranging from the specification, to design, implementation, integration, verification, validation, and production release. The standard ISO 26262 is an adaptation of the Functional Safety standard IEC 61508 for Automotive Electric/Electronic Systems. ISO 26262 defines functional safety for automotive equipment applicable throughout the lifecycle of all automotive electronic and electrical safety-related systems. The first edition (ISO 26262:2011), published on 11 November 2011, was limited to electrical and/or electronic systems installed in ...
