SOTIF – Safety of the Intended Functionality
Scope ISO PAS 21448
Scope
This document is intended to be applied to intended functionality where proper situational awareness is
critical to safety, and where that situational awareness is derived from complex sensors and processing
algorithms; especially emergency intervention systems (e.g. emergency braking systems) and
Advanced Driver Assistance Systems (ADAS) with levels 1 and 2 on the OICA / SAE standard J3016
automation scales. This edition of the document can be considered for higher levels of automation,
however additional measures might be necessary. This document is not intended for functions of
existing systems for which well-established and well-trusted design, verification and validation (V&V)
measures exist at the time of publication (e.g. Dynamic Stability Control (DSC) systems, airbag, etc.).
Some measures described in this document are applicable to innovative functions of such systems, if
situational awareness derived from complex sensors and processing algorithms is part of the
innovation.
