Abstract:
1. A control apparatus for a first motor-assisted bicycle for detecting a pedaling torque applied to a crankshaft with a pedaling force sensor, controlling a motor unit of the first motor-assisted bicycle in a regenerative control process to charge a battery if a torque value of the detected pedaling torque is equal to or smaller than a predetermined level, and controlling the motor unit in an assistive control process if said torque value is greater than said predetermined level, wherein said control apparatus includes: a data storage unit for storing a program to control the first motor-assisted bicycle in modes including a motor assisted mode and a regenerated mode while the first motor-assisted bicycle is being used by a user, and a control quantity corrector for correcting the assistive control process and the regenerative control process, based on predetermined threshold levels related to the assistive control process and the regenerative control process, which are stored in said data storage unit, wherein said control apparatus stores therein states of charge of said battery when a power supply of said first motor-assisted bicycle is turned on and off, stores said motor assisted mode and the regenerated mode in the single event of use of the first motor-assisted bicycle in said data storage unit by storing of a quantity representative of a difference between the stored states of charge of said battery when the power supply of said first motor-assisted bicycle is turned on and off, and calculates correction coefficients for correcting the assistive control process and the regenerative control process based on said difference if an absolute value of said difference is greater than a predetermined value.
