The invention discloses an electric power-assisted bicycle. The electric power-assisted bicycle comprises a bicycle frame, a wheel mechanism, a pedal assembly, a driving mechanism, a rotation measurement sensing assembly and a controller. The driving mechanism is arranged on the frame and is in transmission connection with the wheel mechanism. The rotation measurement sensing assembly is arranged on the rotation center shaft and/or the pedal assembly and used for measuring the rotation condition of the rotation center shaft so as to output calibration position data, rotation state data and torque data. The controller is coupled with the driving mechanism and the rotation measurement sensing assembly and used for determining whether the rotation center shaft rotates to a preset calibration position or not according to the calibration position data and determining the current position of the rotation center shaft according to the calibration position data and the rotation state data. And according to the current position and the torque data, the rotation acting force applied by the pedal assembly to the rotation middle shaft is determined, and the driving mechanism is controlled to apply the output torque corresponding to the rotation acting force to the wheel mechanism. By means of the mode, the power assisting effect on riding of the user can be improved.

    本申请公开了一种电助力自行车,电助力自行车包括车架、车轮机构、脚踏组件、驱动机构、转动测量传感组件和控制器。驱动机构设置于车架,并与车轮机构传动连接。转动测量传感组件设置于转动中轴和/或脚踏组件,用于测量转动中轴的转动情况,以输出标定位置数据、转动状态数据和力矩数据。控制器耦接驱动机构和转动测量传感组件,用于根据标定位置数据确定转动中轴是否转动至预设标定位置,根据标定位置数据和转动状态数据确定转动中轴的当前位置,根据当前位置和力矩数据确定脚踏组件对转动中轴所施加的转动作用力,控制驱动机构向车轮机构施加与转动作用力相对应的输出力矩。通过上述方式,能够提高对用户骑行的助力效果。
