Joint torque calculation device, joint torque calculation method, and joint torque calculation program

摘要

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
