Pirelli’s Cyber Tire might become highway agencies’ newest assistant

Pirelli’s sensor-embedded Cyber Tire is starting to find a whole new niche helping traffic agencies. When we first learned of the smart tire, it was making its debut fitted to McLaren’s then-new plug-in hybrid supercar. As an alternative to a tire pressure monitoring system fitted to the car’s wheels, the Cyber Tire wirelessly reports its temperature and pressure to its car via Bluetooth Low Energy, along with some specific information about the tire itself.

Since then, Pirelli has continued to develop the technology. When it created Cyber Tires for the Pagani Utopia, it allowed a car to tailor its antilock braking and electronic stability control to the specific rubber fitted to the wheels. Right now, a car’s ABS or ESC will be tuned regardless of the tires it’s fitted to.

But a high-performance summer tire acts quite differently from a winter tire, not just because of the composition of the rubber but also due to the tread pattern, depth, and stiffness, not to mention factors like sidewall stiffness. And the Utopia can take advantage of that fact.

So far, that’s an academic concern to everyone but the few with the means and desire to drive a Utopia. But last year, Bosch, which worked on the Pagani integration with Pirelli, signed a deal with the tire maker allowing it to do the same for its other OEM clients. Indeed, just last month, Aston Martin announced it would adopt the Cyber Tire.

“There are plenty that I cannot yet mention now that are in an advanced phase of proof of concept,” said Piero Misani, Pirelli’s CTO. At first, Pirelli used its own AMG demo car to show the system to OEMs, but more recently, it has been integrating the technology into several new OEMs. Pirelli is “already working with two projects in Europe and two projects in China, for example, and this will lead to another one in England, Korea. We will start in January, and this will lead for sure to effective projects in the future,” Misani told me.

“Two weeks ago, a European manufacturer tested… the traction control and stability with a dramatic improvement in stability and the traction,” he said. “The nice part of the story is that there is not only an objective improvement—2 or 3 meters in braking distance—but there is also from these customers always a better feeling… which is something that is very important to us because numbers are for technicians, but from our customer’s perspective, the pleasure to drive also very important.”

The headline said something about traffic?

While the application described above mostly serves the Cyber Tire-equipped car, the smart tires can also serve the greater good. Earlier this year, we learned of a trial in the Italian region of Apulia that fitted Cyber Tires to a fleet of vehicles and then inferred the health of the road surface from data collected by the tires.

Working with a Swedish startup called Univrses, Pirelli has been fusing sensor data from the Cyber Tire with cameras. Misani offered an example.

“You have a hole [in the road]. If you have a hole, maybe the visual [system] recognizes and the tire does not because you automatically try to avoid the hole. So if the tire does not pass over the hole, you don’t measure anything,” he said. “But your visual system will detect it. On the opposite side, there are some cracks on the road that are detected from the visual system as something that is not even on the road, but they cannot say how deep, how is the step, how is it affecting the stability of the car and things like this. Matching the two things, you have the possibility to monitor in the best possible way the condition of the road.”

“Plus thanks to the vision, you have also the possibility to exploit what we call the vertical status—traffic signs, the compatibility between the condition of the road and the traffic signs,” he said.

The next step is a national program in Italy. “We are investigating and making a project to actively control not the control unit of the car but the traffic information,” Misani said. “On some roads, you can vary the speed limit according to the status; if we can detect aquaplaning, we can warn [that] at kilometer whatever, there is aquaplaning and [the speed limit will be automatically reduced]. We are going in the direction of integrating into the smart roads.”
