Abstract
The safety assurance process represents a crucial part of the automotive development. The responsibilities of the human driver will be shifted to the responsibility of the vehicle system which results in a significant increase of scope. Within the context of ISO 21448 Safety of the Intended Function (SOTIF), we are concerned with avoiding costly analysis and rework due to inclusion of SOTIF scenarios which are out of scope. Our approach is to introduce a formal specification of the Operational Design Domain (ODD) to define the scope by mapping and simplify common elements between different domains. For this purpose, we expand the hazardous scenarios analysis within the SOTIF process to identify hazardous situations which can occur inside the ODD. Our results suggest that using this approach helps reducing the cost of the safety analysis process.
