This three-day seminar is designed as an overview of Safety of the Intended Functionality (SOTIF) requirements of ISO/FDIS 21448:2019. It provides the basis to manage the development of new products utilizing electrical and electronic elements to assure functional safety at the nominal design.

ISO 26262:2018 is concerned with the safety of the new driving systems as related to the malfunction behaviors due to the E/E failures. It does not concern itself with the nominal performance of the item.

SOTIF is related to the reasonably foreseeable misuse of the function by the driver or to the functional insufficiencies of the intended functionality. There are different methods for the qualitative analysis of the functional insufficiencies to ensure SOTIF for new E/E automotive systems. This seminar will provide an overview on the application of SOTIF for the new E/E automotive systems and present a system-theoretic approach to identify the foreseeable misuse scenarios and analyze the functional insufficiencies of the system in compliance with the ISO/FDIS 21448:2019 standard.
