The invention relates to an electric bicycle traction force control method which comprises the following steps: S1, acquiring the wheel speed of a driving wheel at the moment t1; s2, the wheel speed of the driving wheel is collected again at the moment t2; s3, calculating the wheel speed change rate of the driving wheel in the (t2-t1) time period; and S4, intervention or non-intervention of traction force control is performed according to the wheel speed change rate of the driving wheel. On the basis of not adding any device, the traditional traction force control effect is achieved by means of a control algorithm and existing conditions, when a driving wheel slips, electric control of a motor is rapidly involved, the slipping phenomenon is rapidly restrained by reducing output power and even generating electronic braking, the driving safety is improved, and the applicability is high.

    本发明涉及一种电动自行车牵引力控制方法,包括以下步骤,S1、在t1时刻采集驱动轮轮速;S2、在t2时刻再次采集驱动轮轮速;S3、计算在(t2‑t1)时间段内的驱动轮的轮速变化率;S4、根据驱动轮的轮速变化率进行牵引力控制的介入或不介入。本发明在不增加任何器件的基础上依靠控制算法利用现有条件实现传统牵引力控制效果,在驱动轮发生打滑现象时,电机电控迅速介入,通过减小输出功率甚至产生电子制动,来迅速遏制打滑现象,增加行车安全,可应用性强。
