The invention provides a power-assisted control system and method of an electric power-assisted bicycle and the electric power-assisted bicycle. The system comprises two pedaling frequency sensors, two pedaling frequency signal processing circuits, a micro-control unit and a driving chip. Wherein each pedaling frequency sensor is used for generating a path of pedaling frequency signal; each treading frequency signal processing circuit is used for processing the corresponding treading frequency signal; the micro-control unit is used for controlling the driving chip according to the processed two paths of treading frequency signals; and the driving chip is used for driving or stopping driving a motor of the electric power-assisted bicycle under the control of the micro-control unit. Therefore, the pedaling frequency signal can be monitored, and the motor is controlled according to the monitored pedaling frequency signal, so that the power-assisted control of the electric power-assisted bicycle is realized, the power-assisted safety of the electric power-assisted bicycle is ensured, and the safety of a rider can be ensured.

    本发明提供一种电助力自行车的助力控制系统、方法及电助力自行车,系统包括:两个踏频传感器、两个踏频信号处理电路、微控制单元和驱动芯片;其中,每个踏频传感器,用于产生一路踏频信号;每个踏频信号处理电路,用于对对应的踏频信号进行处理;微控制单元,用于根据处理后的两路踏频信号对驱动芯片进行控制;驱动芯片,用于在微控制单元的控制下驱动或者停止驱动电助力自行车的电机。由此,能够对踏频信号进行监测,且根据监测到的踏频信号对电机进行控制,从而实现对电助力自行车的助力控制,有利于保证电助力自行车助力时的安全性,可以保障骑行者的安全。
