Abstract:
    According to the present invention, a wheel identifying apparatus includes a plurality of transceivers, each of which is located on one of a plurality of wheels of a vehicle, a triggering device, a receiver, and a wheel identifier. The triggering device is located on a body of the vehicle at different distances from the transceivers and works to transmit a trigger signal. Each of the transceivers works to receive the trigger signal, determine the strength of the trigger signal thereat, correct the determined strength using a correction value, and transmit a response signal indicative of the corrected strength. The receiver works to receive all the response signals transmitted by the transceivers. The wheel identifier works to identify, for each of the response signals received by the receiver, the wheel on which the transceiver having transmitted the response signal is located based on the corrected strength indicated by the response signal.
