The invention provides an electric power-assisted wheel capable of being automatically folded and unfolded and a control method of the electric power-assisted wheel. In the control method, the electric power-assisted wheel is connected with the bottom of an external vehicle through an elastic damping mechanism and a lifting mechanism; the electric power-assisted wheel can be moved to the ground through the lifting mechanism so as to provide additional moving power for an external vehicle; and the lifting mechanism is driven by a motor, after the electric power-assisted wheel descends to the ground, the electric power-assisted wheel adjusts the supporting force on the vehicle according to the descending stroke of the electric power-assisted wheel, the motor resistance of the motor is increased due to the increase of the supporting force, when the current of the speed reducing motor rises to a threshold value due to the increase of the motor resistance, the controller of the motor judges that the supporting force of the electric power-assisted wheel meets the requirement of the external vehicle, the motor is stopped, and the lifting mechanism stops moving the electric power-assisted wheel. The electric power-assisted wheel can provide power assisting for a multi-wheel manpower vehicle, and can control the supporting force of the electric power assisting wheel, so that the electric power assisting wheel can cooperatively work with an original driving wheel of the vehicle.

    本发明提出一种能自动收放的电动助力轮及其控制方法,所述控制方法中,电动助力轮经弹性的减震机构、升降机构与外部车辆底部相连;所述电动助力轮可由升降机构移至地面,以向外部车辆提供额外的移动动力;所述升降机构由电机驱动,当电动助力轮下降至地面后,电动助力轮以其下降行程调整对车辆的支撑力,支撑力的增大使电机的电机阻力加大,当减速电机因电机阻力加大而使其电流上升至阈值时,电机的控制器判定电动助力轮的支撑力满足外部车辆需要,电机停机,升降机构停止移动电动助力轮;本发明能为多轮的人力车辆提供助力,而且能对电动助力轮的支撑力进行控制,使电动助力轮能与车辆的原有行驶轮协同工作。
