LE CASTELLET, France (May 18, 2005) – Seeking to push the envelope in vehicle mobility, Pirelli S.p.A. is developing “cyber” tires and wheels that monitor operating conditions constantly and feed that information into a vehicle's onboard dynamic control systems.
Pirelli also has market-ready tire-pressure monitoring systems under the X-Pressure name that can alert drivers of low-pressure situations any of four ways—optically via a valve cap; acoustically via the onboard electronic management system; via Blue Tooth mobile phone technology; or visually via on-board systems.
Pirelli demonstrated these and other extended mobility technologies—including a version of its motorcycle tire-based Safety Wheel System for sport-utility vehicles—May 16 at the Paul Ricard High Tech Test Track near Marseilles, France.
* The Cyber Tire monitors a tire's operating condition via built-in sensors that transmit information via an aerial positioned inside the tire.
* The Cyber Wheel monitors wheel movements that can be used to evaluate the so-called hub forces by using a special algorhythm of calculation, developed by Pirelli in collaboration with the Milan Polytechnic.
* The Safety Wheel System uses a pressurized tank integrated into the rim that activates when tire pressure drops below a pre-set threshhold, reinflating the tire to the prescribed pressure and alerting the driver of the problem.
