Claim 0:
1. A driving device for an electric assisted bicycle, comprising:
a motor configured to provide a driving torque required by the electric assisted bicycle to move forward;
a rotation speed sensor configured to sense a rotation speed value of one of a crank and a chainring of the electric assisted bicycle;
a torque sensor configured to obtain an average torque value applied by the crank to the chainring of the electric assisted bicycle; and
a controller coupled to the motor, the rotation speed sensor, and the torque sensor, and configured to control an output of the motor in response to the rotation speed value and the average torque value,
wherein when the rotation speed value is higher than an idle rotation speed value, and lower than or equal to a high-speed rotation speed value, and the average torque value is greater than a preset torque value, the controller controls the motor to provide an output corresponding to the average torque value.
