The invention provides an electric bicycle speed control method and device, an electric bicycle and a storage medium. The method comprises the steps of obtaining an actual wheel speed signal and a target wheel speed signal of the electric bicycle; obtaining a first actual wheel speed value of the electric bicycle at the first time point according to the actual wheel speed signal; obtaining a first target wheel speed value of the electric bicycle at the first time point and a first target wheel speed change signal of the electric bicycle at the first time point according to the target wheel speed signal; obtaining a first control rate according to the first actual wheel speed value; obtaining a second control rate according to the first target wheel speed change signal; obtaining a third control rate according to a wheel speed error value between the first target wheel speed value and the first actual wheel speed value; determining a target value of a motor control parameter according to the first control rate, the second control rate and the third control rate; and controlling the motor to act based on the target value of the motor control parameter.

    本申请提供了一种电动自行车速度控制方法、装置、电动自行车及存储介质,该法包括:获取电动自行车的实际轮速信号和目标轮速信号;根据实际轮速信号,获得电动自行车在第一时间点的第一实际轮速值;及根据目标轮速信号,获得电动自行车在第一时间点的第一目标轮速值和在第一时间点的第一目标轮速变化信号;根据第一实际轮速值,获得第一控制率;根据第一目标轮速变化信号,获得第二控制率;及根据第一目标轮速值与第一实际轮速值间的轮速误差值,获得第三控制率;根据第一控制率、第二控制率和第三控制率,确定电机控制参数的目标值;基于电机控制参数的目标值控制电机动作。
