ABSTRACT:
A tire information detecting apparatus includes an interrogator which transmits an interrogation signal toward a tire in a vehicle at a transmitting timing, and receives a reply signal including tire information at a receiving timing so as to process the signals. A responder is disposed in the tire and has a sensor excited by a predetermined frequency signal for detecting tire information so as to return the reply signal to the interrogator at the receiving timing in responding to the interrogation signal. A mixer unit receives the interrogation signal having a first signal and a second signal which is spaced the predetermined frequency away from the first signal, from the interrogator, and outputs a signal of the frequency difference between the two signals to the responder by mixing the first and second signals.
