ABSTRACT:
A tire inflation pressure sensing apparatus according to the invention includes a plurality of transmitters, each of which is provided on one of a plurality of wheels of a vehicle, and a receiver provided on a body of the vehicle. Each transmitter includes a pressure sensor working to generate a pressure signal representative of an inflation pressure of a tire on a corresponding one of the wheels and a noise receiver working to receive a noise generated by a noise source in the vehicle. Each transmitter is configured to transmit the pressure signal and the received noise to the receiver. The receiver is configured to determine the inflation pressures of tires based on the pressure signals and make a determination for each of the transmitters as to whether the transmitter is provided on a front-wheel or a rear-wheel of the vehicle based on a level of the corresponding received noise.
