Abstract:
1. A tire condition monitoring system for a vehicle having a chassis and a tire, the system comprising: a tire-side transmitter/receiver, mounted on the tire, for detecting a tire condition and transmitting tire condition information as a response signal including the detected tire condition in response to a request signal; and a chassis-side transmitter/receiver, mounted on the chassis of the vehicle, for transmitting the request signal to the tire-side transmitter/receiver and receiving the tire condition information from the tire-side transmitter/receiver, wherein the tire-side transmitter/receiver includes control means for measuring an interval between two successive reception time points of the request signal transmitted from the chassis-side transmitter/receiver as a travel speed of the vehicle, the two successive reception time points each being defined as a point at which the tire-side transmitter/receiver rotates into a communication range of the chassis-side transmitter/receiver, and for controlling a time point of transmission of the response signal based on the travel speed of the vehicle so that the response signal is transmitted when the tire-side transmitter/receiver is in the communication range of the chassis-side transmitter/receiver.
