The invention discloses an energy regenerative braking method and device for a power-assisted bicycle, and the method comprises an energy regenerative braking mode and a normal running mode in the forward riding process of the power-assisted bicycle. In the energy feedback braking mode, a button arranged on the handle sends a signal to the motor, the motor starts to start after receiving the signal, the electric control clutch is powered on, the output end of the motor is connected with the wheels, then the motor stops running, the wheels drive the motor to rotate, the motor generates electricity, and braking is conducted while energy recovery is achieved; in the normal running mode, the motor stops or the electric control clutch is not electrified when the wheels are driven to rotate, the output shaft of the motor is not connected with the wheels (in a sliding state) or the wheels are driven to rotate (in a power-assisted state), and the power-assisted bicycle runs normally. A rider can select sliding, power-assisted riding or energy recovery by himself/herself, the riding process is simplified, and the riding comfort is improved.

    本发明公开了一种助力自行车用能量回馈制动方法与装置,当助力自行车在向前骑行的过程中,分为能量回馈制动模式和正常行驶模式;在能量回馈制动模式下,通过把手上设置的按钮向电机发送信号,电机收到信号后开始启动,电控离合器通电,使电机的输出端与车轮相连接,然后电机停止运行,车轮带动电机转动,电机进行发电,实现能量回收的同时进行制动;在正常行驶模式下,电机停止或驱动车轮旋转电控离合器不通电,电机的输出轴不与车轮相连接(滑行状态)或驱动车轮旋转(助力状态),助力自行车正常行驶。本发明可以让骑行人员自行选择滑行和助力骑行或是能量回收,简便了骑行过程,提高了骑行舒适度。
