As the innovation of emergency intervention, ADAS (Advanced Driver Assistance Systems), and self-driving technologies progresses, the automotive industry is already formulating ways to ensure the safety of these solutions in our vehicles. ISO/PAS 21448:2019 (SOTIF) is the first universal standard addressing the safety of the intended functionalities in our vehicles.
Our webinar helps you get familiar with the concept of “Safety of the Intended Functionality” (SOTIF) and the relationship between ISO 26262:2018 and ISO/PAS 21448:2019. This webinar helps you understand how to design and configure codebeamer to address SOTIF requirements. Learn configuration tips & tricks and to gain early access to our SOTIF-ready workspace free of charge!
