To provide a device for estimating the degree of fatigue of power transmitting components and a method for estimating the degree of fatigue of power transmitting components that are capable of estimating the degree of fatigue of each component in a power transmission system.SOLUTION: Provided is a device 20 for estimating the degree of fatigue of power transmitting components in a power transmitting system 2 from a motor/generator 3 (drive source) to driving wheels 9 (wheels), including: an estimating unit 22 which estimates the degree of fatigue of a power transmitting component on the basis of the magnitude and direction of torque acting on the power transmitting component; and an output unit 23 which outputs a signal indicating that the degree of fatigue has exceeded a threshold if the degree of fatigue exceeds a prescribed threshold that is set in advance.SELECTED DRAWING: Figure 4

    【課題】動力伝達系の部品毎に疲労度合いを推定することができる動力伝達部品の疲労度合い推定装置および疲労度合い推定方法を提供する。【解決手段】モータ/ジェネレータ3(駆動源)から駆動輪9(車輪)までの動力伝達系2における動力伝達部品の疲労度合い推定装置20であって、動力伝達部品に作用するトルクの大きさおよび方向に基づいて、動力伝達部品の疲労度合いを推定する推定部22と、疲労度合いがあらかじめ定められた所定のしきい値を超えた場合に、疲労度合いがしきい値を超えたことを示す信号を出力する出力部23と、を備える。【選択図】図4
