To provide a method for estimating a bending stiffness characteristic variation of a tire and measuring tread wear amount of the tire.SOLUTION: A tire wear measurement device using a bending stiffness variation of a tire comprises: a signal receiving unit 110 measuring acceleration inside the tire with respect to an axial direction, which is a radial direction of the tire, for each point inside the tire; a signal analysis unit 120 to which signal information is transferred from the signal receiving unit, and which estimates a tread wear rate of the tire by calculating a bending stiffness variation rate of the tire using axial acceleration inside the tire; a transmitting unit 130 to which analysis information being information on the tread wear rate of the tire is transferred from the signal analysis unit, and transmits the transferred analysis information; and a control module 200 to which the analysis information is transferred from the transmitting unit, and which generates a control signal for a vehicle to which the tire is installed. Meanwhile, a physical change of the bending stiffness variation of a tire is derived using "Flexible Ring Tire Model" which is a mathematical model.SELECTED DRAWING: Figure 1

    【課題】タイヤの曲げ剛性の特性変化を推定し、タイヤトレッドの摩耗量を測定する方法の提供。【解決手段】タイヤの曲げ剛性の変化を用いたタイヤの摩耗測定装置は、タイヤの半径方向である軸方向に対するタイヤ内部の加速度をタイヤ内部の各点に対して測定する信号受信部110と、信号受信部から信号情報を伝達されて、タイヤ内部の軸方向の加速度を用いてタイヤの曲げ剛性の変化率を演算することにより、タイヤトレッドの摩耗率を推定する信号分析部120と、信号分析部からタイヤトレッドの摩耗率に対する情報である分析情報を伝達されて送信する送信部130と、送信部から分析情報を伝達されてタイヤが設置された車両に対する制御信号を生成する制御モジュール200と、を備える。一方、これの物理的変化を数学的モデル(Flexible Ring(フレキシブルリング、弾性リング)Tire Model)を用いて、これを導き出した。【選択図】図1
