To meet evolving industry requirements, ISO 26262:2018 also includes an extended vocabulary, more-detailed objectives, objective-oriented confirmation measures, information on managing safety anomalies, references to cyber security, updated values for hardware architecture metrics, and the means to evaluate hardware elements. In order to address concerns around emerging technologies, the update offered guidance on model-based development and software safety analysis, dependent failure analysis, semiconductors, fault tolerance, safety-related special characteristics, and software tools, as well as expanding its scope to include trucks, buses, trailers, semitrailers, and motorcycles. Originally released in 2011, ISO 26262:2011 underwent a major update to Part 2 in 2018. What is more, it details how to assign an acceptable risk level to a system or component and document the overall testing process. In general, ISO 26262 manages functional safety by guiding and regulating the entire product lifecycle process, from conceptual development through to decommissioning. One such norm, the ISO 26262 automotive functional safety standard, is a derivative of IEC 61508, the generic functional safety standard for electric and electronic systems (E/E), which addresses the needs for an automotive-specific international standard focusing on safety critical components.
Speaking at the Society of Automotive Engineers’ (SAE) 2018 WCX conference in Detroit, Ken Kelzer, GM’s vice president of global vehicle components and subsystems, told attendees: “As we look toward the future challenges of new technologies, it is critical that we are unified in the development and application of standards.”
