Reusable architectural patterns for achieving functional safety including redundancy (homogeneous, heterogeneous, diverse), monitoring and supervision, graceful degradation, plausibility checking, watchdog timers, and fail-operational/fail-safe strategies. Each pattern mapped to applicable ASIL levels, hazard types, failure modes, and verification approaches. Includes implementation guidance, trade-offs, and real-world automotive examples from powertrain, chassis, and ADAS domains.
