Intelligent auxiliary power system of bicycle

An intelligent auxiliary power system of a bicycle includes an electric motor, an electric auxiliary drive module and an energy storage device; the electric motor is arranged on a wheel drum of a wheel of the bicycle; the energy storage device is coupled to the electric motor through the electric auxiliary drive module; the electric auxiliary drive module includes an inertia sensor, an electric energy recovery device, a processor, and a motor drive unit; the processor receives information including a forward momentum and a vehicle attitude, of the bicycle, acquired by the inertia sensor, and acquires the revolution speed and the torque of the electric motor through operation; and the processor performs operation through a control algorithm according to all the information, and then the motor drive module drives the electric motor, or the electric energy recovery device charges up the energy storage device with electric energy generated by the electric motor. Accordingly, when a rider rides the bicycle, the in
