Classification: CPC B | IPC B

Claim 14:
15. A transmission device, comprising:
a motor operated in an operating period;
a torque sensor configured to output a plurality of torque signals corresponding to a pedal force; and
a controller coupled to the motor and the torque sensor, wherein 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,

wherein the controller is further configured to:
compute and determine 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.
