The invention provides a speed safety control system and method and an electric power-assisted bicycle, and the system comprises a sensor unit which is used for detecting a speed signal and a pedaling frequency signal; a sensor signal processing circuit; the key monitoring circuit is used for generating key voltage according to the action of a boosting key of the electric boosting bicycle; the riding control subunit is used for judging whether the electric power-assisted bicycle is in a riding state or not and controlling the driving chip according to the processed speed signal when the electric power-assisted bicycle is in the riding state; and the pushing control subunit is used for judging whether the electric power-assisted bicycle is in a pushing state or not and controlling the driving chip according to the processed speed signal when the electric power-assisted bicycle is in the pushing state. Therefore, when the electric power-assisted bicycle is in a riding state or a pushing state, the motor is controlled according to the speed signal, so that the power-assisted and speed control of the electric power-assisted bicycle is realized, the safety of the bicycle during advancing is guaranteed, and the riding safety is guaranteed.

    本发明提供一种速度安全控制系统、方法及电助力自行车,系统包括:传感器单元,用于检测速度信号和踏频信号;传感器信号处理电路;按键监测电路,用于根据电助力自行车的助推按键的动作产生按键电压;骑行控制子单元,用于判断电助力自行车是否处于骑行状态,及在处于骑行状态时根据处理后的速度信号对驱动芯片进行控制;推行控制子单元,用于判断电助力自行车是否处于推行状态,及在处于推行状态时根据处理后的速度信号对驱动芯片进行控制。由此,在电助力自行车处于骑行状态或者推行状态时,根据速度信号对电机进行控制,从而实现电助力自行车助力与速度的控制,有利于保证自行车前行时的安全性,保障骑行安全。
