<P>PROBLEM TO BE SOLVED: To provide an assistive power control apparatus of a motor-assisted bicycle for controlling a motor to generate an assistive torque depending on the pedaling force of a rider. <P>SOLUTION: The assistive power control device (54) of the motor-assisted bicycle (10) detects a rotating torque value of a crankshaft (38) rotated when a rider steps on pedals (40L, 40R) by a torque sensor (80), controls a motor (50) to generate an assistive power determined using the rotating torque value, calculates a rotation angle of the crankshaft when a present rotating torque value is detected from a time period from a timing of detection of a peak position of the rotating torque value to a timing of detection of the rotating torque value, calculates a pedaling force applied when the rider steps on the pedals from the calculated rotation angle of the crankshaft and the detected present rotating torque value, and determines the assistive power of the motor according to the calculated pedaling force. <P>COPYRIGHT: (C)2013,JPO&INPIT |
