SOTIF (Safety of the Intended Functionality)

SOTIF (Safety of the Intended Functionality) is an automotive safety discipline defined by ISO 21448. It complements functional safety standards such as ISO 26262. It addresses hazardous behavior that can arise even when a system functions as designed, especially in advanced driver assistance or automated driving systems. SOTIF focuses on specifying, developing, verifying, and validating intended functions so they remain adequately safe, particularly in situations involving sensor limitations or misinterpretation of environmental data.
