PROBLEM TO BE SOLVED: To estimate joint torque of a joint of a bicycle crew member, with a simple configuration.SOLUTION: A joint torque calculation system 10 comprises: a joint torque calculation device 12; a detection unit 14; an input unit 16, and an output unit 18. The joint torque calculation device 12 comprises: a data acquisition unit 122; a torque estimation unit 124; and a variation amount estimation unit 126. The joint torque calculation device 12 calculates a variation amount of joint torque in the case of displacing a saddle position using load data showing a load applied to a pedal, skeleton data, and structure data and outputs the variation amount to the output unit 18. The variation amount estimation unit 126 determines, from a plurality of estimated variation amounts of joint torque, the saddle's position at which power owned by a bicycle crew member can be maximally exerted.SELECTED DRAWING: Figure 1

    【課題】簡単な構成で、自転車乗員の関節の関節トルクを推定する。【解決手段】関節トルク演算システム10は関節トルク演算装置12、検出部14、入力部16及び出力部18を備えている。また、関節トルク演算装置12は、データ取得部122、トルク推定部124、及び変動量推定部126を備えている。関節トルク演算装置12は、ペダルにかかる負荷を示す負荷データと、骨格データ及び構造データと、を用いて、サドル位置を変位させた場合の関節トルクの変動量を演算し、出力部18へ出力する。また、変動量推定部126では、複数推定した関節トルクの変動量から自転車乗員が有する力を最大限に発揮することが可能なサドルの位置も決定する。【選択図】図1
