To determine an arousal state with high accuracy.SOLUTION: A buckle includes a sensor for outputting an output signal according to breathing of a crew of a vehicle, a detection unit for detecting a breathing frequency component by frequency analysis from the output signal, and a determination unit for determining an arousal state of the crew based on the frequency component detected by the detection unit. An arousal state determination method is configured as follows: the sensor provided at the buckle outputs the output signal changing according to the breathing of the crew of the vehicle; the detection unit detects the breathing frequency component by the frequency analysis from the output signal; and the determination unit determines the arousal state of the crew based on the frequency component detected by the detection unit.SELECTED DRAWING: Figure 2

    【課題】覚醒状態を高精度に判定すること。【解決手段】車両の乗員の呼吸に応じて変化する出力信号を出力するセンサと、前記出力信号から、前記呼吸の周波数成分を周波数分析により検出する検出部と、前記検出部により検出される前記周波数成分に基づいて、前記乗員の覚醒状態を判定する判定部とを備える、バックル。バックルに設けられるセンサは、車両の乗員の呼吸に応じて変化する出力信号を出力し、検出部は、前記出力信号から、前記呼吸の周波数成分を周波数分析により検出し、判定部は、前記検出部により検出される前記周波数成分に基づいて、前記乗員の覚醒状態を判定する、覚醒状態判定方法。【選択図】図2
