Michelin introduces 'cured-in-tyre' RF identification

12 February 2003 Telecoms, Datacoms, Wireless, IoT

Michelin recently announced that it is introducing RF (radio frequency) tyre identification technology as the first company to begin fleet testing an RF tyre identification system for passenger and light truck tyres.

Michelin engineers have developed an RFID transponder that is manufactured into the tyre and stores vital tyre identification information. The tyre ID number can be associated with the vehicle identification number (VIN). This makes the tyres uniquely identifiable with an individual vehicle, telling when and where the tyre was made, maximum inflation pressure, tyre size, etc.

The transponder consists of an antenna and an integrated circuit the size of a match head that has a higher data capacity than a bar code. It is encoded and decoded with a handheld device and, unlike a bar code, remains unaffected by soil or deterioration over time. The information on the circuit can be modified to reflect new data, such as the VIN number of the vehicle on which it is mounted. The ICs are manufactured by Fairchild Semiconductor and Philips. As part of the supply arrangement, Philips provides its latest I.CODE HSL IC. Both ICs are under licence from Intermec Technologies.

Michelin's contribution to this RFID system was its modification of the antenna attached to the electronic device and the proprietary treatment of the device that makes it possible to vulcanise the assembly into the tyre. While some other tyre makers have demonstrated similar technology, Michelin says its RFID tag is the first to meet the Automotive Industry Action Group's B-11 standard for North America, as a 'cured into the tyre' solution. Operating at UHF, the Michelin RFID tag can be interrogated by the reader from some 60 cm or more away from the transponder. Once collected, the information can be stored in a database for accurate and easy retrieval.
