Aurora successfully demonstrates AV fault management system

A reliable fault management system is essential for safely operating autonomous vehicle fleets for commercial customers, helping to pave the way to full commercialization. With this in mind, self-driving tech firm Aurora Innovation Inc recently delivered its Beta 3.0 product update and demonstrated its fault management system – specifically the Aurora Driver’s ability to detect system issues and respond by safely pulling over to the side of the road without any human involvement.

The company says it achieved its milestone ahead of schedule, following its implementation on Aurora-powered trucks operating on public roads at highway speeds. “Any of a number of factors, from blown tires to damaged sensors, can compromise a vehicle while on the road,” stated Sterling Anderson, Aurora co-founder and chief product officer. “Safely detecting and responding to those issues is essential for a reliable self-driving product operating at scale. Our fault management system lays the groundwork for safe autonomous operations without vehicle operators, chase vehicles or remote human fallback systems.”

Aurora’s fault management system

The fault management system is designed to actively monitor the health of the vehicle, including the self-driving software, sensors and onboard computer. When it detects an issue, the system will intervene, navigating the vehicle to a safe stopping location from which the issue can be addressed. The company says this is a critical capability for removing vehicle operators, meeting the rigorous requirements of Aurora’s Safety Case Framework, and ultimately scaling its autonomous vehicle fleets broadly.

To demonstrate this system on public roads, engineers introduced artificial faults that the Aurora Driver interpreted as sensor damage. The Aurora Driver responded by activating the autonomous vehicle’s hazard lights, reducing its speed and safely pulling over to the side of the road.

As with other elements of the Aurora Driver, the fault management system was developed and extensively tested first in Aurora’s Virtual Testing Suite, enabling safer, more rapid implementation in the real world. As it prepares to launch its commercial products, the company says its fault management system architecture will continue to advance to recognize and respond to additional system issues while on the road.

“Ensuring our autonomous vehicles are safe, even when system issues occur, is a key component of completing our Safety Case Framework,” said Nat Beuse, VP of safety for Aurora. “This is an important step toward removing vehicle operators and commercially deploying driverless vehicles.”

The demonstration of the fault management system complements Aurora’s release of its Beta 3.0 product update. This update focuses on end-to-end autonomous operations between Aurora’s terminals that help advance the Aurora Driver toward commercial readiness, including navigating complicated surface streets between terminals and highways.
