Abstract
A detection/communication apparatus to be installed on a vehicle having a plurality of tires. The apparatus includes: (a) tire state detectors which are provided on the respective tires and each of which detects a state of a corresponding one of the tires; (b) local transceivers which are provided on the respective tires and which transmit tire data sets relating to the respective tires; (c) a central receiver which is provided on a vehicle body and which receives the tire data sets transmitted by the local transceivers; (d) a particular-signal transmitter which is provided on the vehicle body and which transmits a particular signal; and (e) data-transmission modifiers which are provided on the respective tires. Each of the data-transmission modifiers is operable depending upon a state of reception of the particular signal by a corresponding one of the local transceivers, to modify transmission of a corresponding one of the tire data sets by the corresponding one of the local transceivers.
