The invention relates to a motor driving method and device of an electric power-assisted bicycle and the electric power-assisted bicycle, motors of the electric power-assisted bicycle comprise a high-speed motor and a low-speed motor which are respectively used for driving front and rear wheels of the electric power-assisted bicycle. And then controlling the high-speed motor and the low-speed motor to switch the operation state according to the size relationship between the state data and a preset switching threshold value. Through the method, the high-speed motor and/or the low-speed motor can be driven to work according to the state data when the electric power-assisted bicycle is in different running states, automatic control over motor driving is achieved, and therefore the use reliability of the electric power-assisted bicycle is improved.

    本申请涉及一种电助力自行车的电机驱动方法、装置及电助力自行车,电助力自行车的电机包括高速电机和低速电机,分别用于驱动电助力自行车的前后轮,首先获取电助力自行车的状态数据,然后根据状态数据和预设切换阈值的大小关系,控制高速电机和低速电机切换运行状态。通过上述方法,可以在电助力自行车处于不同的行驶状态时,根据状态数据驱动高速电机和/或低速电机工作,实现电机驱动的自动控制,从而提高了电助力自行车的使用可靠性。
