Abstract
Abstract
Modern automotive system must comply with strict safety requirements. This paper focuses on two aspects of safety: functional safety per ISO 26262 (FS) and the safety of the intended functionality (SOTIF) per ISO PAS 21448. The FS encompasses a lifecycle ensuring the absence of unreasonable risks due to internal failures of the system. SOTIF concentrates on non-deterministic parts and algorithms (e.g. neural networks), as full specification of their performance is out of reach now. At the same time, FS and its lifecycle are better known to the community and have better history of implementation. This paper presents an approach to integration of FS and SOTIF requirements based on FS lifecycle.
