The invention particularly discloses an adaptive electric power-assisted bicycle control system and method. The adaptive electric power-assisted bicycle control system comprises a data acquisition unit and a controller, wherein the controller is used for detecting whether the bicycle is in a state without assistance or not according to speed information, seat load information, the pedal rotating direction and brake pressure information of the bicycle; if it is judged that a rider selects the power-assisted mode, power-assisted work is carried out according to a power-assisted mode selected bythe rider; and if it is judged that the rider does not select the power-assisted mode, the current rotating speed and moment of the motor are calculated according to the speed information of the bicycle, the seat load information, the pedal frequency information, the motor current information and the pedal torsion information, then the gradient information of the riding road is obtained, and the motor and the transmission mechanism are controlled to conduct assistance work. The system has the advantage that the output of the motor is automatically calculated to meet the riding requirement of the rider.

    本发明具体公开了一种自适应电动助力自行车控制系统及方法,一种自适应电动助力自行车控制系统,包括,数据获取单元;控制器,用于根据自行车的速度信息、座椅负重信息、脚踏旋转方向及刹车压力信息检测自行车是否处于不需要助力的状态,若判断骑行人选择了助力模式,按照骑行人选择的助力模式进行助力工作,若判断骑行人没有选择助力模式,根据自行车的速度信息、座椅负重信息、脚踏踏频信息、电机电流信息及脚踏扭力信息计算当前电机转动速度及力矩,再获取骑行道路坡度信息,控制电机及传动机构进行助力工作。本发明具有自动计算出电机出力以满足骑行者的骑行需求的优点。
