Abstract: The draft international standard of the future ISO 21448 (addressing the SOTIF / Safety of the planned functionality) was published at the beginning of this year. At this point, the ISO/DIS 21448: 2021 is publicly available on the ISO website and can be used for operational applications. The target date for publication of the International Standard remains the first quarter of 2022, despite the pandemic situation.
As a reminder, SOTIF is an aspect of Systems Safety complementary to Functional Safety addressed in ISO 26262. The ISO 26262 series assumes that the intended function is safe and addresses failures that could cause a hazardous event. The scope of ISO 21448 is the analysis, and the safety demonstration, of the intended function in absence of failure, in particular by evaluating its ability to cope with the various road environments with which it may be confronted in operation. These two aspects are of paramount importance for the safety of ADAS and Automated Driving functions.
