Claim 7:
8. An operation method configured for a power assisted electric bicycle, wherein the power assisted electric bicycle comprises a motor, a torque sensor and a controller, the motor is operated in an operating period and the torque sensor is configured to output a plurality of torque signals corresponding to a pedal force, wherein the operation method comprises:
receiving the torque signals from the torque sensor;
determining a peak and a valley, which is adjacent to the peak, among the torque signals;
computing and determining a pedaling period between the peak and the valley, which is adjacent to the peak, among the torque signals; and
generating 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,
wherein the method further comprises:
computing and determining the operating period according to a vehicle speed of the power assisted electric bicycle at a time point; and
wherein the vehicle speed of the power assisted electric bicycle at the time point is computed based on a rotation speed of the motor at the time point.
