How is Bridgestone Innovating Tyre Technology?
For modern vehicles, in premium and electric cars, road noise is a big problem, and the higher the levels of cabin quietness, the better the experience of driving. With the advanced noise reduction solution of B-Silent Technology, Bridgestone Tyres Bedford has advanced solutions for reducing road noise while not compromising on the performance of the tyres. In particular, the technology is very beneficial for models of luxury sedans and electric vehicles since engine noise is already negligible, and hence, the road noise is more prominent.
In one such example of how Bridgestone’s B-Silent Technology specifically works, it is focused on targeting air cavity resonance, a major cause of tyre noise. Within the tyre, air oscillations due to contact with the road surface can lead to loud sounds being created in the vehicle cabin. In order to solve this problem, B-Silent has a polyurethane foam layer inside the tyre that is able to absorb vibrations and make less noise.
Furthermore, by combining tread pattern optimisation with the technology, the rolling resistance produces minimum impact noise. It reduces turbulence and provides a smoother and quieter ride due to the design of the tread. The combination of structural modifications has led to a large reduction of mid- to high-frequency noise (200-400 Hz), usually the noisiest inside the vehicle.
Noise reduction is also a focus of other manufacturers besides Bridgestone. The similar solutions using Michelin’s Acoustic Technology, Pirelli’s Noise Cancelling System (PNCS), and Continental’s ContiSilent Technology focus on a quieter ride. However, key differences are:
Both Michelin Acoustic Technology uses a polyurethane foam insert, and it is aimed primarily at the electric vehicle segment, as cabin noise sensitivity is higher.
Pirelli’s PNCS utilises thick foam layers in combination with improved sidewall design that helps to minimise structural as well as resonance-specific noise.
The ContiSilent Technology of Continental is built on the use of special rubber compounds as well as foam layers, which makes their tyres especially good for reducing rolling noise.
Of course, Bridgestone’s B-Silent Technology is a favourite because of its balanced approach, providing noise reduction for all the vehicle types, including passenger cars, SUVS, and high-performance vehicles.
Autonomous vehicles (AVS) are spurring tyre manufacturers to revisit basic tyre design. Independent of his relationship with TÜV SÜD, the other issue we face is that autonomous vehicles cannot do without tyres that are better connected, durable, networked, and also adaptable to change and performance. Along this transformation, Bridgestone has been investing in smart, airless, and energy-efficient tyres to promote the future of mobility.
Sensor integration is one of the most substantial technological advances in the development of the tyre for autonomous vehicles. With built-in sensors monitoring:
Tyre pressure and temperature
Real-time tread wear analysis
Road conditions and grip levels
Through communications with the vehicle's autonomous control system, these smart tyres modify the driving pattern of the vehicle according to the condition of these tyres. For example, if the AV driver feels that the tyres indicate wet or slippery roads, it will alter its acceleration and braking to remain as safe as possible.
With AI and cloud-based analytics, the Bridgestone Predictive Tyre Management System gives real-time diagnostics and allows fleet operators to anticipate tyre maintenance, lower downtime, and improve efficiency.
It is important that the autonomous vehicles, which are primarily used in ride-sharing and delivery services, are kept as maintenance-free as possible. Bridgestone is putting money into airless tyre technology that removes puncture and blowout risk. The use of a unique structural design in these tyres ensures that the shape and performance of these tyres are maintained without the need for air pressure.
A great innovation is thanks to self-healing tyres that use intelligent rubber compounds to heal minor cuts or punctures on their own. AV operations become more cost-effective and sustainable as the frequency of tyre replacements is reduced.
Due to the fact that most autonomous vehicles will be electric, there is a priority for energy efficiency in tyre design. Focusing on ultra-low rolling resistance tyres, Bridgestone is working on ways to reduce vehicle energy consumption by reducing the amount of energy used to move the vehicle forward.
Furthermore, the technology Bridgestone also has is ENLITEN Technology, which is designed specifically to make tyres lighter, yet still without sacrificing grip and durability. For EVS, this is particularly useful, as tyres Bedford must work with an instant torque and at the maximum range.
Decisions need to be made by autonomous vehicles that can operate efficiently over highway terrains as well as within urban streets. Adaptive tread pattern development will develop patterns that can change based on temperature, moisture levels, and road conditions.
For example, 3d-printed smart tread blocks may change their shape and stiffness according to the sensor data. In rainy conditions, if an AV is driving, the tread pattern can expand to disperse water to increase grip and lower hydroplaning risk. In dry conditions, the tread contracts to allow for better rolling efficiency.
