Abstract
A tire side device is provided with a vibration detection unit that outputs a detection signal corresponding to the magnitude of tire vibration, a control unit that performs to generate road surface data indicating a road surface condition that appears in the waveform of the detection signal, and a first data communication unit that transmits the road surface data. Furthermore, a vehicle body side system is provided with a second data communication unit that receives the road surface data transmitted from the first data communication unit, and a road surface determination unit that determines the condition of the road surface that the vehicle is traveling on the basis of the road surface data. In addition, sensing is performed by the control unit under different sensing conditions at the tire side device of at least one tire among a plurality of tires and the tire side device of at least one other tire among the plurality of tires, and road surface data generated on the basis of the different sensing conditions is transmitted from the first data communication unit.
