Abstract
An electricity aided bicycle and an auxiliary power controlling method thereof are provided. The electricity aided bicycle includes a driving circuit, a rotating speed detector and a command voltage generator. The driving circuit receives a command voltage, and drives an auxiliary motor of the electricity aided bicycle based on the command voltage. The rotating speed detector generates a detection signal having a plurality of pulses based on a rotation status of a driving gear of the electricity aided bicycle. The command voltage generator receives the detection signal, and is configured to: calculate times between two adjacent pulses in the detection signal, operate numerical value derivation operation based on the times to generate an estimated velocity value, set an electricity aid strategy table and calculate the command voltage based on the estimated velocity value and the electricity aid strategy table.
