The invention discloses a motor control method of a power-assisted bicycle, which considers that when the power-assisted bicycle runs under different road conditions, the current manpower output power and an electronic transmission of the bicycle can correspondingly change along with the difference of the road conditions, and the electronic transmission of the bicycle can correspondingly change along with the change of the current manpower output power. Therefore, the target motor torque can be obtained based on the change relation between the current manpower output power and the target motor output power so as to control the data of the motor, the gyroscope and the torque sensor, and the automatic output adjustment of the motor is completed by adding an algorithm to the data of the gyroscope and the torque sensor. According to the electric bicycle, the mechanical gears are automatically adjusted according to road conditions, the riding comfort and safety are improved, and meanwhile the riding pleasure of the rider is reserved. 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,本考虑到助力自行车行驶在不同的路况条件下,当前人力输出功率和车辆的电子变速器会随着路况的不同相应的发生变化,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,陀螺仪和扭矩传感器的数据再加上算法完成电机的自动输出调整,从而使骑行者的脚踏力维持在舒适的区间内,本发明中机械档位根据路况自动调节,提高了骑行的舒适性、安全性的同时,保留了骑行者的骑行乐趣。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。
