Functional safety is at the heart of every innovation in automotive technology, ensuring systems perform safely even when faults occur. However, as our industry pushes the boundaries with autonomous vehicles and AI-driven solutions, new challenges emerge. That’s where ISO 26262, SOTIF (ISO 21448), and the upcoming ISO 8800 standards come into play. But what do they mean, and how do they differ?
ISO 26262: The Foundation of Functional Safety
Let’s start with the cornerstone: ISO 26262. This standard is the Bible for functional safety in automotive systems, addressing the risks of hardware and software failures. It answers questions like:
ISO 26262 provides a structured framework to identify, assess, and mitigate risks caused by system malfunctions, ensuring vehicles can operate safely even in faulty conditions. Think of it as the backbone of automotive safety.
SOTIF (ISO 21448): Beyond Failures—The Safety of the Intended Functionality
But what happens when a system works exactly as designed—yet still causes danger? This is where SOTIF steps in.
Imagine an advanced driver assistance system (ADAS) that misinterprets a snow-covered road sign. There’s no hardware or software failure—just an unforeseen scenario. SOTIF addresses these gaps, focusing on unknown or unintended risks in complex environments, especially in systems relying on machine learning and perception.
Key takeaway: SOTIF deals with ensuring systems are robust against the unknown, complementing ISO 26262’s fault-based approach.
ISO 8800: Shaping the Safety of AI in Automotive
As artificial intelligence becomes central to autonomous vehicles, traditional methods struggle to address its unique risks. Enter ISO 8800, the emerging standard designed to ensure the safe implementation of AI in automotive systems.
This standard tackles questions like:
While ISO 26262 and SOTIF provide robust foundations, ISO 8800 pioneers new ground by focusing on the inherent unpredictability of AI models and their ability to learn and evolve over time.
The Big Picture
These standards aren’t competing—they’re building blocks for a safer future:
Together, they’re redefining how we think about safety in modern automotive systems, enabling the industry to deliver groundbreaking technology without compromising on trust.
