Functional Safety (ISO 26262)
Automotive standard ensuring that electrical and electronic systems operate safely under faults.
ISO 26262 defines processes for assessing and mitigating risks in vehicle electronics. It requires hazard analysis, validation, and documentation at each development stage. Systems are assigned Automotive Safety Integrity Levels (ASIL) from A to D based on risk severity. Redundant design, fail-safe mechanisms, and rigorous testing ensure reliability. Functional safety is crucial for autonomous and ADAS features where malfunction could endanger lives.
