Waymo mentioned it it’s prepared to start publicly testing what it says is the primary redundant autonomous Class 8 trucking platform on public freeways.
In 2020, Waymo partnered with Daimler Truck to develop a redundant, level-4-autonomous-ready truck platform powered by the Waymo Driver. Within the coming weeks, the corporate will start testing these autonomous Freightliner Cascadias on public freeways throughout Dallas and Phoenix. The testing will make use of Waymo’s lately opened trucking facility in Dallas, a switch hub that’s an early endpoint of its driverless route. In response to officers, it is the primary custom-designed hub of this sort designed for deploying autonomous vans.
Waymo and Daimler Truck North America shared some insights with reporters in a digital briefing Aug. 23, together with the truth that these redundant programs will want extra energy and add some weight to the vans.
Why Redundancy is a Should for Autonomous Vans
Whereas there are fairly a couple of different self-driving-truck corporations which can be creating autonomous expertise, Waymo and Daimler say each autonomous truck wants backup programs to make sure protected operation with out a human behind the wheel. That’s going to be a should to deploy operations at scale, in line with firm officers.
“In case you’re going to do something with even remotely cheap scale, that is one thing it’s a must to handle, so this partnership turned completely essential,” mentioned Boris Sofman, Waymo’s head of engineering for trucking.
“Daimler brings the expertise, manufacturing, testing and validation capabilities that no autonomous-vehicle firm on the market has,” mentioned Jason DiGrande, engineering lead for Waymo’s OEM program.

To supply a truck prepared for the Waymo Driver to be put in, Daimler Truck needed to meet greater than 1,500 Waymo Purposeful Necessities. These have an effect on each {hardware} and software program, together with:
- Backup computing
- Redundant energy programs
- Redundant steering
- Redundant braking
- Redundant inertial measurement programs for car positioning
- Cybersecurity
- Fail-safe and fail-operational
Suman Narayanan, director of engineering at Daimler Truck North America, defined that “at Daimler truck globally, we’ve at all times relied on a playbook, a business car improvement system. Our partnership with Waymo has given us a singular alternative to evolve the method to accommodate rising expertise.
“We’re creating a sturdy, realizable and scalable redundant car platform.”
Redundant Techniques
For example, the truck has two digital brake controllers to make sure brake efficiency in case the first system fails. The steering system, equally, has two servo motors permitting lateral management in case of an digital or hydraulic failure.
Excessive-speed redundant CAN bus communication gives uninterrupted, high-integrity, safe communications to the digital management items wanted. And there’s a redundant low-voltage energy internet that can retailer and supply energy to essential ECUs (such because the braking and steering programs) if wanted.
A brand new Digital Park Brake provides the autonomous driving system the power to use and launch truck and trailer park brakes with CAN alerts. If there’s a malfunction, the system will use the digital braking system to pneumatically activate the parking brake.
All these electronics and redundant programs require extra energy.
“One of many key issues about [automated driving systems] is we’re all realizing the quantity of energy the computer systems and sensors want,” mentioned DTNA’s Narayanan. “We would have liked to reinvent how we are able to generate the ability for this technique. We’ll generate extra energy at a better voltage with a brand new 48V alternator, however the car nonetheless stays at a 12V structure.”
To compensate in case the alternator is now not in a position to generate energy, battery storage, monitored by particular person battery monitoring sensors, has been elevated by 50%.
“We perceive the magnitude of what we’ve undertaken,” Narayanana mentioned. “That is large. This requires us to deal with one problem at a time. … we’re navigating by means of these challenges and tackling one step at a time.”

The Waymo Driver
Despite the fact that automobiles and vans have totally different driving traits, Waymo mentioned its intensive expertise in creating and deploying self-driving automobiles is a boon to autonomous truck improvement as nicely.
Utilizing the identical system for each permits the corporate to spend money on creating options for distinctive challenges, such because the totally different car dynamics and form of the truck in comparison with automobiles.
Sensors are personalized to take care of the form of the truck. A mix of lidar, cameras and radar are supposed to be redundant and complement one another, offering the Waymo Driver an overlapping “view” of the world round it.
There are two fifth-generation lidar sensors on the truck, plus further lidar for near-range notion. Cameras can detect out to a couple of kilometer (1000 meters), permitting the Waymo Driver to preemptively be defensive, reminiscent of altering lanes for a car stopped on a shoulder.

Subsequent-generation radar is especially efficient coping with climate situations reminiscent of rain and fog.
In lots of circumstances, in line with Waymo, the sensors and cameras can detect issues before the human eye can, particularly at night time or in unhealthy climate.

“That is our fifth-generation Waymo driver,” Sofman mentioned, which has powered each its automobiles and its vans. “We consider ourselves as constructing the driving force, not the car, and discover partnerships like we’ve with Daimler.”
He identified that Waymo has vans outfitted with the Waymo Driver function each single day throughout the Dallas-to-Houston route and others, albeit with a security driver behind the wheel. Producing a number of miles on the highway is essential to coaching the system so it is aware of what to do, whether or not confronted with a standard state of affairs reminiscent of a automotive on the shoulder, or one thing extra uncommon like a barbecue grill falling out of the again of a pickup truck at 65 mph forward of the truck.
“Now we have fairly a repository of attention-grabbing examples,” Sofman mentioned. “You might have to have the ability to take care of these type of decisions.”
Daimler Truck North America’s Excessive Desert Proving Grounds in Madras, Oregon, will play an vital half in testing and validation of the autonomous-ready Cascadia.
Waymo’s DiGrande cited for example “shaker testing,” simulated vibration take a look at the place 4 weeks of testing are equal to 1 million actual world miles. “How’s all the things going to carry up with the extra mass and weight we’re including? That equals about 10 months of testing on the proving grounds.” And earlier than deploying software program onto the bottom car, for steering, brakes, low voltage system, a sequence of electrical take a look at benches have been constructed to check them earlier than deploying them on the truck.
Waymo’s Path Ahead
Waymo is waiting for the subsequent steps in commercializing its autonomous Driver. Right this moment, mentioned Sofman, Waymo owns and operates a take a look at fleet of Cascadia vans, placing a number of miles on the highway, each for improvement and to make its security case.

“In parallel, we’re constructing relationships with clients that can run pilots, so we get to be taught the operational greatest practices we want to have the ability to execute and find out how our product matches what clients anticipate.”
Subsequent comes early absolutely autonomous deployment with no human driver within the cab.
“Then as we begin to scale business deployment, we go from a Waymo-owned and -operated fleet to 1 the place a buyer would buy a truck from Daimler that will have a Waymo Driver.”
Finally, Sofman defined, with sufficient scale, the complete construct of the truck would occur on the Daimler manufacturing facility, with Waymo supplying the Waymo Driver parts.
“For the time being, the vans we’ve constructed that shall be hitting the highway have been inbuilt our Waymo Detroit facility,” mentioned DiGrande, with Freightliner transport the Waymo-ready truck to its facility for set up of the Waymo Driver system.
Different partnerships embrace J.B. Hunt, Uber Freight, CH Robinson, and Ryder, which helps to develop the “ecosystem” for these vans.
