Abstract
A vehicle wheel information obtaining apparatus for obtaining wheel information relating to a wheel of a vehicle. The apparatus includes: (a) a wheel state detector which detects a state of the wheel; (b) a transmitter which is provided on the wheel and which transmits a wheel data set containing a wheel state data representing the detected state of the wheel and a wheel identification data identifying the wheel; (c) a receiver which is provided on a vehicle body and which receives the wheel data set transmitted by the transmitter; (d) a data processor which processes the wheel data set received by the receiver; and (e) a communication-intensity reducing device which reduces a transmission strength of the transmitter or/and a reception sensitivity of the receiver, such that the transmission strength or/and the reception sensitivity is lower when the data processor is in an identification-data registering mode, than when the data processor is in a wheel-state data obtaining mode.
