GENEVA, Switzerland—Goodyear is offering visitors to the 2014 Geneva Auto Salon sneak peeks at two innovations it has in the works, an intelligent tire concept using embedded microchips and a twin air-chambered SUV tire.
The “chip-in-tire” technology, seen at the Geneva show in a Dunlop SportMaxx RT tire, allows the tire to communicate directly with a vehicle's onboard computer to enhance vehicle performance, Goodyear Dunlop Europe said.
The system, according to Goodyear, uses a battery-less microchip, attached to the inside of the tire, that can relay information on tire pressure, temperature and tire identification details to the vehicle's computer, which then is able to refine the vehicle's longitudinal and lateral control algorithms on the fly to deliver improved driving performance.
Among the improvements Goodyear claims is possible are reduced stopping distances when ABS is activated, improved cornering response, improved yaw stability and optimized stability control systems.
“Today's advanced vehicle control systems can greatly benefit from tire specific information,” said Senior Engineer Marc Engel. “We have always understood that when we were able to gather this information, we could deliver new levels of driving performance to the car.
“Tire properties change significantly and tire type, inflation and temperature play a major role,” he said. “If a vehicle knows those dynamic properties, its control systems can take them into account and deliver an improved overall performance.”
Placing the chip inside the tire means the chip is not subject to damage, Goodyear said.
The Akron-based tire maker is testing the system for market implementation, and said it worked with Huf Hülsbeck & Fürst GmbH & Co. K.G., a Velbert, Germany-based maker of mechanical and electrical locking systems, tire pressure monitoring systems and telematic systems, to develop and refine the technology.
Goodyear joins several other tire companies offering what has become known as intelligent tires. Among them are Continenal A.G., Michelin, Nokian Tyres P.L.C., Pirelli Tyre S.p.A. and Yokohama Rubber Co. Ltd.
