Patent ID: 8686846

Claim:
A tire condition monitoring system, comprising: a condition detector for detecting a predetermined tire condition, provided on each tire of a vehicle; a plurality of tire condition acquisition devices having a transmission device for transmitting the detected tire condition information by electromagnetic waves; receiving antenna for receiving the electromagnetic waves transmitted from each of the tire condition acquisition devices, wherein the receiving antenna is centrally located on the vehicle and wherein the receiving antenna comprises a plurality of receiving antennas fewer in number than the plurality of tire condition acquisition devices; and a monitoring device, which is connected by a cable to the receiving antenna, for receiving the tire condition information transmitted from each of the tire condition acquisition devices and displaying the tire condition information for each tire; wherein an electric field intensity display is provided for displaying an electric field intensity of the electromagnetic waves transmitted from each of the tire condition acquisition devices, wherein the electric field intensity display switches between display of electric field intensities for different tires of the vehicle, and the electric field intensity display is configured to simultaneously display the electric field intensity and text indicating both an air pressure and temperature of a selected tire.
