Title:
TIRE INFORMATION SYSTEM AND TIRE USED FOR THE SAME
Document Type and Number:
WIPO Patent Application WO/2006/118011
Kind Code:
A1
Abstract:
Signal transmission by an electromagnetic field between a sensor unit installed on a tire inner surface and a sensor control unit installed on a vehicle body side is attenuated at a tire wall surface that is present in between them, and as a result, sensing sensitivity is reduced. A booster antenna (18) is embedded in a tire wall surface between a sensor unit (6) and a sensor control unit (10). The booster antenna (18) is a coil antenna and is constructed such that a resonance frequency according to the inductance and capacity component of the antenna is according to a frequency f0 of a transmission electromagnetic field of the sensor control unit (10). The booster antenna (18) is provided at a position where it is magnetically coupled to the coil antenna of the sensor unit (6), and signal transmission between the sensor unit (6) and the sensor control unit (10) is performed through the booster antenna (18).
