METHOD FOR MEASURING PEDAL ROTATION PERIOD FOR BICYCLE AND ENERGY CONSUMPTION, PEDAL ROTATION PERIOD MEASURING INSTRUMENT, AND ENERGY CONSUMPTION MEASURING INSTRUMENT

摘要

PROBLEM TO BE SOLVED: To obtain an instrument for measuring energy consumption for bicycles that has less number of parts, is simple in structure, and is inexpensive. SOLUTION: A measuring instrument has a detector 1 for detecting torque, a means 2 for calculating a torque value based on an input signal from the torque detector 1, a means 3 for setting a time when a torque value exceeds a threshold by comparing the torque value inputted from the torque operation means 2 with the threshold to a pedal stepping start time, a means 6 for calculating a pedal rotary period based on a current time and the pedal stepping start time, and a means 7 for calculating an energy consumption based on the torque value that is outputted from a means 5 for adding torque and a pedal rotary period.
