The invention provides a starting control system and method for an electric power-assisted bicycle, the system comprises a key monitoring circuit, a micro-control unit and a driving chip, and the micro-control unit comprises a switch control subunit and a boosting control subunit; the key monitoring circuit is used for generating key voltage according to the actions of the switch key and the boosting key; the switch control subunit is used for controlling the key monitoring circuit according to the key voltage and the duration of the key voltage; and the boosting control subunit is used for controlling the driving chip according to the key voltage and the duration of the key voltage. Therefore, when the electric power-assisted bicycle is in the power-on state or the power-off state, control is carried out according to the key voltage and the duration time of the key voltage, the situation that the electric power-assisted bicycle is powered on accidentally or boosted accidentally is avoided advantageously, and therefore safety is improved advantageously.
本发明提供一种电助力自行车的启动控制系统、方法,系统包括:按键监测电路、微控制单元和驱动芯片,微控制单元包括开关控制子单元和助推控制子单元;按键监测电路,用于根据开关按键和助推按键的动作产生按键电压;开关控制子单元,用于根据按键电压和按键电压的持续时间,对按键监测电路进行控制;助推控制子单元,用于根据按键电压和按键电压的持续时间,对驱动芯片进行控制。由此,在电助力自行车处于通电状态或者断电状态时,根据按键电压和按键电压的持续时间进行控制,有利于避免电助力自行车意外上电或者意外启动助推,从而有利于提升安全性。
