An assisting force control device for use in a bicycle with an electric motor and a crankshaft includes a driving member coupled co-rotatably to the crankshaft, a strain sensor disposed on the driving member, a torque calculation unit coupled to the strain sensor for calculating and outputting a torque signal, a rotational speed detection unit mounted on the crankshaft for outputting a rotational speed detecting signal, and a control unit. The control unit includes a receiving module for receiving the rotational speed detecting signal and the torque signal, and a processing module coupled to the receiving module for generating a force control signal to control the electric motor accordingly. |
