Open Sesame! Why Functional Safety is the Master Key to Open the Door for Linux into Automotive
summary
Argues that Linux can meet automotive functional safety by building an embedded Linux V2X traffic‑light demonstrator that targets ASIL B and shows concrete measures: CRCs on the dataflow, redundant second‑path calculations for data processing, and a separate microcontroller doing three-layer monitoring with hardware feedback and deadline checks to enforce a 10 ms deterministic envelope. Implementation is demonstrated working at system level; open issues are certification of Linux, end‑to‑end car↔infrastructure feedback loops and defining global system states.
