The invention relates to a riding power-assisted control method and a riding power-assisted control device. The riding power-assisted control method comprises the following steps: acquiring a treading torque of a middle shaft when the middle shaft is treaded at a current gear; according to the current gear and the treading torque, the power assisting ratio is determined; determining an assistance torque according to the treading torque and the assistance ratio, and controlling an assistance motor to output the assistance torque; wherein under the current gear, the power assisting ratio corresponding to the treading torque in the high treading torque section is larger than the power assisting ratio corresponding to the treading torque in the low treading torque section. According to the mode, the system can determine the power assisting ratio corresponding to the treading torque according to the magnitude of the treading torque, so that the needed power assisting torque is output, and compared with the mode that the ratio of the power assisting torque to the treading torque is fixed at the same gear in the prior art, the power assisting torque is more stable. In different riding scenes, a rider does not need to select a power-assisted gear or a transmission gear to adjust the power-assisted ratio any more, and the riding experience during riding is improved.
本发明涉及一种骑行助力控制方法及骑行助力控制装置,包括步骤:获取中轴在当前档位下踩踏时的踩踏扭矩;根据所述当前档位以及所述踩踏扭矩,确定助力比;根据所述踩踏扭矩及所述助力比确定助力扭矩,控制助力电机输出所述助力扭矩;其中,在所述当前档位下,高踩踏扭矩段中所述踩踏扭矩所对应的助力比大于低踩踏扭矩段中所述踩踏扭矩所对应的助力比。这种方式,系统能够根据踩踏扭矩的大小,确定与之所对应的助力比,从而输出所需要的助力扭矩,相对于现有技术中在同一档位下助力扭矩与踩踏扭矩的比值固定的方式,在不同骑行场景中不再需要骑行者选择助力档位或传动档位而调节助力比,提高了骑行时的骑行体验。
