Control apparatus for motor-assisted bicycle

A control apparatus for a motor-assisted bicycle which is capable of selectively performing an assistive control process and a regenerative control process depending on the state of charge and the state of discharge of a battery detects a pedaling torque applied to a crankshaft (48) with a pedaling force sensor (110), controls a motor unit (28) of the motor-assisted bicycle (10) in a regenerative control process to charge a battery (44) if the torque value of the detected pedaling torque is equal to or smaller than a predetermined level, and controls the motor unit (28) in an assistive control process if the torque value is greater than the predetermined level. The control apparatus (250) includes a storage unit (252) for storing an assisted state and a regenerated state in a single event of use of the motor-assisted bicycle (10) by a user, and a control quantity corrector (276) for correcting a control quantity of the assistive control process and a control quantity of the regenerative control process based on the assisted state and the regenerated state which are stored in the storage unit (252).
