Self-driving truck

Self-driving trucking company Kodiak Robotics has demonstrated its ‘fallback’ system, which can autonomously pull a self-driving truck over to the side of the road in the event of a truck or system failure.

The company pointed out that the ability to perform a safe, reliable fallback, otherwise known as a ‘minimal risk condition’, is critical to safely deploying driverless trucks on public roads. To assist this safety feature, the company’s Kodiak Driver self-driving system evaluates the performance of more than 1,000 safety-critical processes and components 10 times each second, in both the self-driving stack and the underlying truck platform. These components include truck-related components such as the engine, oil levels and tire pressure, as well as autonomous vehicle system components such as sensors and software processes. Should any of these components fall outside the acceptable performance parameters, the Kodiak Driver automatically executes a fallback plan, safely pulling the truck over to the side of the road. For example, if flying roadway debris were to damage one of the autonomous truck’s sensors, the Kodiak Driver would detect the damage and safely pull the truck over.

While critical failures like blown tires and engine problems are uncommon in motor vehicles, they can be very dangerous if handled inappropriately. When a human is not in the vehicle to react to these scenarios, it is essential to have a fallback technology that responds accordingly. Just as a brainstem can react quickly without waiting for input from the brain, Kodiak’s actuation control engine (ACE) safety computer executes a fallback without input from the Kodiak Driver’s main computer. The ACE is a universal interface to all truck platforms, and Kodiak is currently working to certify the safety computer to the highest automotive-grade standard. Kodiak’s fourth generation of trucks includes two ACE units for redundancy and additional safety. Should the ACEs lose connection with the Kodiak Driver’s main computer for any reason, from a communications failure to a loose cable, the system will automatically execute a fallback.

Don Burnette, founder and CEO of Kodiak, said, “To launch an autonomous vehicle without a human driver, you must ensure the vehicle will protect motorists in the case of a truck or autonomous system failure. Implementing a fallback system is a fundamental necessity to achieve that level of safety. We are the first autonomous trucking company to demonstrate this capability on public roads. We have integrated fallback technology into the Kodiak Driver’s architecture from the beginning – it would be incredibly hard to add this capability as an afterthought.”

Burnette continued, “It’s essential that the self-driving technology powering an 80,000 lb [36,287kg] semi-truck is capable of reacting swiftly and safely, no matter what happens. Kodiak’s autonomous trucks are constantly monitoring themselves and preparing to pull over in case of a fault, just like a human would. Kodiak’s ability to perform safe fallbacks depends on our own custom-designed safety computer, the ACE. One of the many crucial functions the Kodiak ACE is responsible for is ensuring that our autonomous system can guide the truck to a safe stop when necessary.”
