The invention discloses a motor control method of a power-assisted bicycle, which considers that the current manpower output power can correspondingly change along with different road conditions when the power-assisted bicycle runs under different road conditions. The target motor output power can be obtained according to the determined current manpower output power, the current motor output power and the target manpower output power, and the target motor output power can correspondingly change along with the change of the current manpower output power; therefore, the target motor torque can be obtained on the basis of the change relation between the current manpower output power and the target motor output power to control the motor, and in the process, the assisting power output by the motor is automatically adjusted on the basis of cooperation of a processor and a related sensor, so that the pedal force of a rider is maintained within a comfortable interval; and the riding comfort is improved. The invention further discloses a motor control device of the power-assisted bicycle and the power-assisted bicycle, and the motor control device and the power-assisted bicycle have the same beneficial effects as the method.

    本发明公开了一种助力自行车的电机控制方法,考虑到助力自行车行驶在不同的路况条件下,当前人力输出功率会随着路况的不同相应的发生变化。根据确定的当前人力输出功率、当前电机输出功率及目标人力输出功率可得到目标电机输出功率,随着当前人力输出功率的变化,目标电机输出功率也会相应的发生变化,因此便可基于当前人力输出功率与目标电机输出功率的变化关系得到目标电机扭矩来控制电机,这一过程基于处理器与相关传感器配合实现对电机输出的助力的自动调节,从而使骑行者的脚踏力维持在舒适的区间内,提高了骑行的舒适性。本发明还公开了一种助力自行车的电机控制装置及助力自行车,具有与上述方法相同的有益效果。
