PROBLEM TO BE SOLVED: To provide a vehicle state determination device, a vehicle state determination program, and a load detection device capable of accurately determining the state of a vehicle by a piezoelectric rubber part incorporated in vibration-proof rubber, and easily detecting load which acts on the vibration-proof rubber.SOLUTION: Load detection devices 13A to 13D detect load which acts on a vibration-proof rubber 10 for suppressing vibration. The load detection devices 13A to 13D detect the load which acts on an axle box 7 with power generated when the axle box 7 vibrates according as a vehicle travels, and monitors the state of a bearing in the axle box 7. The vibration-proof rubber 10 incorporates a piezoelectric rubber part, and the piezoelectric rubber outputs an electric signal in accordance with the load which acts on the vibration-proof rubber 10. A vehicle state determination device 19 monitors the state of the bearing in the axle box 7 on the basis of the scale of a load detection signal output by the piezoelectric rubber part, and determines the presence/absence of an abnormal state such as the damage of the bearing.

    【課題】防振ゴムに内蔵された圧電ゴム部によって車両の状態を正確に判定することができるとともに、防振ゴムに作用する荷重を簡単に検出することができる車両状態判定装置、車両状態判定プログラム及び荷重検出装置を提供する。【解決手段】荷重検出装置13A〜13Dは、振動を抑える防振ゴム10に作用する荷重を検出する。荷重検出装置13A〜13Dは、車両の走行によって軸箱7が振動したときに発生する電力によって、軸箱7に作用する荷重を検出し、この軸箱7内の軸受の状態を監視する。防振ゴム10は、圧電ゴム部を内蔵しておりこの防振ゴム10に作用する荷重に応じて電気信号をこの圧電ゴムが出力する。車両状態判定装置19は、圧電ゴム部が出力する荷重検出信号の大きさに基づいて軸箱7内の軸受の状態を監視し、この軸受の損傷のような異常状態の有無を判定する。【選択図】図3
