Abstract
A driving device and a driving method for an electric assisted bicycle are provided. The driving device includes a motor, a rotation speed sensor, a torque sensor and a controller. The rotation speed sensor senses a rotation speed value of a crank or a chainring of the electric assisted bicycle. The torque sensor obtains an average torque value applied by the crank to the chainring of the electric assisted bicycle. The controller controls an output of the motor in response to the rotation speed value and the average torque value.
