The Automotive Safety Integrity Level (ASIL) is a classification system used in the automotive industry to assess the safety of electronic systems. It helps determine the necessary safety measures based on the potential risks associated with system failures. ASIL is part of the ISO 26262 standard, which focuses on functional safety in road vehicles. There are four ASIL levels: A, B, C, and D, with D being the highest level of safety requirement. Each level corresponds to the severity of potential hazards, the likelihood of failure, and the controllability of the situation. This structured approach ensures that safety-critical systems, such as braking and steering, are designed and tested rigorously.
