The rim with an aerial
The innovative offer of Pirelli Tyre Systems has been enriched by the
presentation of Cyber™ Wheel. It is the first instrumented rim, which,
like Cyber™ Tyre, has also been developed as part of Pirelli's role of
always offering greater added value to the car manufacturers & is, therefore,
original equipment oriented.
Cyber™ Wheel makes it possible to use a rim as a sensor that registers
physical sizes & communicates them to the car. In fact, passing from the
deformation to which the wheel is subjected when the vehicle is moving, the
system is also able to evaluate the so-called hub forces by using a special
algorhythm of calculation, developed by Pirelli in collaboration with the
Milan Polytechnic. It therefore offers in real time information of the greatest
importance to the dynamic control systems that maintain the stability of the
vehicle, information which is vital to the forces that the car & the road
exchange when the vehicle is running.
The operational layout of Cyber™ Wheel repeats in part what takes place
with Cyber™ Tyre. Special sensors located in the rim & energised via radio
frequency by electronics & an aerial in the wheel housing, measure the
deformations, transform them into power & transmit them to the vehicle.
It is important to note how all the systems developed - or those that are under
development by Pirelli - have been designed to be integrated with others
& are personalised in line with the needs of the client, both on the
replacement & original equipment markets.
