To reduce the amount of time-series waveform data measured by an in-tire sensor.SOLUTION: The time-series waveforms for a plurality of rotations of the tire are extracted from time-series waveform data, and the extracted time-series waveforms are converted from the waveforms in a time domain to the waveforms in the frequency domain to generate a representative waveform from a plurality waveforms converted into the frequency domain. In the step of generating the representative waveform, the representative values of the frequency components of the plurality of waveforms converted into the frequency domain are obtained for each frequency, and the obtained representative values of the frequency components are used as the frequency components of the representative waveform to compress the amount of sensor data in the tire.SELECTED DRAWING: Figure 3

    【課題】タイヤ内センサーで計測した時系列波形データのデータ量を削減する。【解決手段】前記時系列波形のデータから、タイヤ複数回転分の時系列波形を抽出し、この抽出された時系列波形を、時間領域の波形から周波数領域の波形に変換した後、前記周波数領域に変換された複数の波形から代表波形を生成する。代表波形を生成するステップでは、前記周波数領域に変換された複数の波形の周波数成分の代表値を周波数毎に求め、前記求められた周波数成分の代表値を、前記代表波形の周波数成分とすることでタイヤ内センサーデータのデータ量を圧縮する。【選択図】図3
