Abstract
A power assisted electric bicycle includes a body, a motor, a torque sensor, and a controller. The motor is operated in an operating period. The torque sensor is configured to output a plurality of torque signals corresponding to a pedal force. The controller is coupled to the motor and the torque sensor. The controller is configured to: receive the torque signals from the torque sensor; determine a peak and a valley, which is adjacent to the peak, among the torque signals; compute and determine a pedaling period between the peak and the valley, which is adjacent to the peak, among the torque signals; and generate an error signal associated with the torque sensor if it is determined that the pedaling period and the operating period fail to meet a default ratio.
