To improve accuracy of detecting a driving state of a driver.SOLUTION: An alarm information notification device 1 includes: an acquisition section 161 for acquiring a physical amount indicating a motion of a seat belt b; a determination section 162 for determining whether or not a frequency component of a change of a physical amount after the acquisition section 161 has acquired a physical amount equal to or more than a predetermined threshold contains a frequency component equal to or more than a predetermined frequency; and a notification section 163 for notifying of alarm information when the determination section 162 determines that the frequency component of the change of the physical amount after acquisition of the physical amount equal to or more than the predetermined threshold contains the frequency component equal to or more than the predetermined frequency.SELECTED DRAWING: Figure 2
【課題】運転者の運転状態の検出精度を向上する。【解決手段】警告情報通知装置1は、シートベルトbの動きを示す物理量を取得する取得部161と、取得部161が所定の閾値以上の物理量を取得した後の物理量の変化の周波数成分が、所定の周波数以上の周波数成分を含むか否かを判定する判定部162と、判定部162が、所定の閾値以上の物理量を取得した後の、物理量の変化の周波数成分が、所定の周波数以上の周波数成分を含むと判定した場合に警告情報を通知する通知部163と、を備える。【選択図】図2
