Autonomous driving is real. Coming out of the realm of research, autonomous vehicles are now on roads around you. These vehicles integrate complex sensor data in real time to maintain their lane, keep a safe driving distance from other vehicles, brake for obstacles in the road, and much more. As engineers, we understand that these capabilities are built from sophisticated electronics, software, and mechanical system. But there is more to a safe vehicle then one tested to operate properly on purchase. Safe vehicles need to remain safe throughout their operating lifetime which means they need to not only operate safely but they also need to fail safely. These two elements mean that the electronics in safe vehicles need to be designed with both functional circuits, for planned operation, and detection circuits, for unplanned failures. This implies that safe electronics require two forms of verification: positive and negative. Positive verification tests that the overall design responds properly to both good and erroneous input. Negative verification tests that the overall design can detect errors in itself. Achieving compliance to ISO 26262 requires a measurement of the extent to which both forms of verification have been completed. For engineers accustom to traditional positive verification, the requirements for ISO 26262 compliance may require more rigorous methodologies than designs that don’t need safety compliance. Moreover, negative verification may require completely new tools and methodologies. This tutorial will explore the challenges in making autonomous vehicles safer and provide attendees with technical guidance they can use to implement the new methodologies they need to achieve compliance for their autonomous driving electronics.
