Understanding the SOTIF Domain and How Safety Analysis Tools Can Perform SOTIF-Related Analysis of E/E Systems

While functional safety standards (e.g., ISO 262626) address hazards caused by malfunctioning electrical/electronic (E/E) systems, they do not cover hazards that can occur even in the absence of system failure. One reason could be the performance limitations of the system or its components (e.g., sensors, perception algorithms). The ISO PAS 21448 standard on safety of the intended functionality (SOTIF) deals with the systematic identification, evaluation and subsequent risk mitigation of these hazards. SOTIF issues are especially important for advanced driver-assistance systems (ADAS) and autonomous vehicle (AV) systems. 

In this on-demand webinar, we will introduce the concepts of SOTIF and illustrate how our safety analysis tool — medini analyze — can perform SOTIF-related analysis of E/E systems. We will introduce a practical workflow incorporating SOTIF and hazard and risk assessment (HARA), which leads to triggering conditions for potentially hazardous behavior. We will also demonstrate how the SOTIF analysis can be combined with the Ansys autonomous (AV) simulation environment in different use cases, e.g., to check effects of triggering conditions by simulation or verify that measures to mitigate SOTIF risks are effective.
