Detroit--Goodyear and Siemens VDO Automotive have developed a tyre information system dubbed "Tire IQ" which the companies claim is the world's most advanced tyre information system. A prototype of the system is fitted to the Ford Shelby GR-1, a high-performance concept coupe, unveiled earlier this week at the 2005 Detroit International Auto Show.
According to a joint statement, a Tire IQ system consists of a passive sensor tag and miniature antenna permanently attached to the inside of each tyre. A corresponding transceiver is mounted in each wheel well of the vehicle. When the transceiver is in transmit mode, it supplies enough power to operate the sensor and trigger a reply from the tyre-mounted tag.
Tire IQ collects and transmits data on pressure and temperature within the tyre. Separate sensors elsewhere on the car collect data on g-forces that can be translated into cornering and braking information.
Joe Gingo, Goodyear's Chief Technical Officer said Tire IQ "will both send and memorise detailed information and uniquely utilise its memory functions to send and record key tyre performance data to advanced vehicle control systems."
