Does anyone know if where i could learn more about the software safety standards for real time applications, such as for car and plane autopilots?

Both EU and US suggestions are very much wanted.

The question is rather broad, only vaguely on-topic, and not a Q&A type of question...

However, I'll give it ago... and fortunately, the US and EU are reasonably well aligned.


The primary functional safety standard for the automotive world is ISO 26262... a massive standard of 13 parts, addressing the whole software and systems engineering lifecycle.

Associated with this, you have ISO/SAE 21434 which addresses the Cybersecurity side of things, and supersedes the longer standing SAE J3061.

As autonomy becomes a bigger issue, a number of parallel projects are ongoing, including UL4600 and several ISO-led works


In the aerospace domain, it's a little more complex and non-integrated... airborne software falls within DO-178C, while programmable electronics comes under DO-254

Work is ongoing to revise these for UAVs


At the software level, testing has been internationally standardised with ISO/IEC/IEEE 29119 (a multi part standard) which brought together a number of existing US and UK led standards in harmonised form... and has been further developed by an multi-national working group ISO/IEC JTC1/SC7/WG26.

Associated with this is the ISO/IEC 250xx SQuaRE family of standards which define quality measures.


Unfortunately, international standards are covered by copyright and are not freely available - hence no links in this answer. They can be sourced thorough the appropriate national body (eg BSI in the UK)

My day job revolves around a lot of these... I'm happy to discuss further (probably better offline... see profile)
