Control apparatus for motor-assisted bicycle

A control apparatus for a motor-assisted bicycle, comprising:

• a torque detecting unit configured to detect a pedaling torque applied to a crankshaft with a pedaling force sensor;
• and
• a control unit configured to control a motor unit of the motor-assisted bicycle in a regenerative control process to charge a battery, if the torque value of the detected pedaling torque is equal to or smaller than a predetermined level, and control the motor unit in an assistive control process, if said torque value is greater than said predetermined level,
• wherein said control apparatus is configured to perform an assistive transient control process with an assistive ratio lower than in said assistive control process while the crankshaft makes a predetermined number of revolutions, and thereafter perform the regenerative control process, if the torque value detected by the pedaling force sensor has a peak equal to or smaller than said predetermined level.
