Abstract
According to the present invention, there is provided a tire pressure monitoring system that includes a first transceiver provided on a body of a vehicle and a second transceiver provided on a wheel of the vehicle. The first transceiver transmits a request signal conveying first information. The second transceiver receives the request signal and transmits, in response to receipt of the request signal, a response signal that conveys a tire pressure information indicating the inflation pressure of a tire fitted on the wheel and second information having a predefined relationship with the first information. The first transceiver receives the response signal, identifies the received response signal as being transmitted by the second transceiver based on the fact that the second information is conveyed by the received response signal, and determines the inflation pressure of the tire based on the tire pressure information contained in the identified response signal.
