Safety of the intended functionality (SOTIF) gives auto developers tools and expertise to ensure safe and reliable vehicle operation that meets regulations and industry standards.
As self-driving and ADAS technologies rapidly evolve, regulators are working to ensure the safety of modern mobility products.
Regulatory standards like ISO/PAS 21448, also known as Safety of the Intended Functionality (SOTIF), will play a key role in shaping the future of vehicle autonomy. Innovations in advanced driver assistance systems (ADAS) will revolutionize the auto industry and potentially enhance road safety. But technological strides have outpaced the establishment of regulatory standards, which is a safety concern.
SOTIF addresses the functional insufficiencies of advanced mobility technologies and provides guidance on design, verification, and validation measures to reduce residual risk and ensure autonomous vehicle safety. SOTIF aims to identify and mitigate risks with a framework for the design and development process.
One of the main challenges of ADAS development is the complex interaction between various sensors, algorithms, and control systems. SOTIF emphasizes identifying potential hazards and considering the intended functionality of the vehicle. It also highlights the need for comprehensive verification and validation processes, which entails testing in various real-world scenarios to ensure reliable and safe performance.
