AV Safety Ventures Beyond ISO 26262

PARIS — The developers of the functional automotive safety standard ISO 26262 aren’t resting on their laurels. They’ve embarked on the creation of a separate standard (ISO 21448), described as “Safety of the Intended Functionality (SOTIF).”

ISO 21448 is said to complement ISO 26262, picking up where ISO 26262 has left off.

The group was motivated to develop SOTIF to avoid unreasonable risks for ADAS and autonomous vehicles (AVs) — even in the absence of malfunctions by hardware and software in vehicles — that might encounter trouble on the road.

Indeed, even ADAS and AV systems otherwise deemed safe — because their hardware complies with ISO 26262 and their software is bug-free — could still fail in some instances. “We don’t think ISO 26262 is enough” to guarantee safety, Riccardo Mariani, Intel Fellow and chief functional safety technologist, told EE Times. The industry has seen the “Uber accident and other events in which autonomous-driving technologies were misbehaving.”
