The expression “where the rubber meets the road” signifies a critical juncture when circumstances become serious. In track racing, tires serve as the essential point of contact between the vehicle and the asphalt. The performance of these tires can be the deciding factor between a triumphant finish at the checkered flag and a disastrous crash into barriers. If they fail to function in harmony, it jeopardizes the entire system.
Understanding this crucial aspect, Pirelli, an esteemed Italian tire manufacturer, has partnered with Bosch, a leading technology firm, to innovate a tire communication network. This collaboration has led to the creation of Pirelli’s ”Cyber Tire,” which is equipped with sensors that collect and relay vital data back to the vehicle. These sensors monitor various parameters such as tire temperature and pressure as well as road conditions, providing real-time feedback for necessary adjustments.
Imagine each tire acting like an individual athlete reporting its status: “I’m ready for action!” or perhaps “Let’s ease up on intensity.”
This technology transcends traditional tire pressure monitoring systems; it represents an advanced level of data collection akin to comparing early mobile phones with today’s smartphones.
Advanced Tire Communication Beyond Basic Metrics
Pirelli has been exploring ways for its tires to communicate directly with vehicles’ onboard computers for nearly 25 years. However, it was only recently that they established their partnership with Bosch Engineering—a company renowned in high-performance automotive circles including brands like Ferrari and McLaren—as well as mainstream car manufacturers.
“Our goal was to extract information from tires since they are our sole connection point between vehicle dynamics and road surfaces,” explains Pierangelo Misani, Pirelli’s Senior Vice President and Chief Technology Officer. “This data is invaluable for enhancing safety and efficiency.”
Advancements in battery technology have made it feasible to incorporate compact power sources within tires without compromising balance—an essential factor since any additional weight can lead to vibrations affecting both comfort and safety. Misani emphasizes that this lightweight system must include components such as accelerometers, chipsets, pressure sensors, temperature sensors—all while ensuring longevity throughout the life cycle of each tire.
Challenges Within a Harsh Environment
Cars are equipped with numerous sensors—some shielded from environmental elements while others are exposed intentionally—but inside a tire presents unique challenges due to its inflated air environment which introduces humidity along with constant deformation under load.
As these sensors navigate through varying diameters during rotation—flattening under weight—they experience rapid deceleration followed by reacceleration at contact points where they meet ground surfaces.
‘We’re dealing with significant acceleration forces,’ Misani notes. ‘Additionally, these components must endure bumps or potholes.’ Thus miniaturization combined with resilience against extreme conditions becomes paramount for sensor functionality within tires.’
‘While sensor integration isn’t new,’ he continues ‘the collaboration between Pirelli and Bosch allows real-time transmission of critical data directly into vehicle controllers—enabling enhanced stability control during driving situations.’ For example: if anti-lock braking systems (ABS) engage without accurate speed or condition readings from tires—their effectiveness could be compromised due simply guessing conditions instead of optimizing performance based on actual metrics.’
Pirelli aims specifically at addressing hydroplaning—a perilous situation where inadequate water drainage leads vehicles losing traction significantly:
“Hydroplaning occurs when contact patches diminish until they’re entirely lifted off surfaces,” explains Misani further illustrating how reduced ground contact limits acceleration capabilities.” With our sensor technology we can detect hydroplaning events effectively.”
Expanding Access To This Innovative Technology
Pagani stands out currently being first hypercar manufacturer utilizing integrated sensor tech within their 850-horsepower Utopia Roadster model but broader applications remain key focus area moving forward according Misani:
“In Pagani Utopia Roadster we actively transmit sensor data back receiver interacting seamlessly controller systems guiding ABS stability controls optimizing responses based current driving scenarios,” he states proudly showcasing proof concept aimed attracting interest other OEMs.”
Pushing boundaries further ahead he adds:”Our vision extends beyond exclusivity—we want share advancements improving overall safety across industry.”
