The invention discloses a control method of a driving motor, a related device and a related system. The device comprises that a shifting block is capable of horizontally moving along a first guide rail and connected with a rear planet row gear ring through a shifting fork, and the rear planet row gear ring can move along with the shifting block; a first-gear combination gear is connected with a shell, and a second-gear combination gear is connected with a planet carrier; when the rear planet row gear ring moves to the position where the first-gear combination gear is located, the rear planet row gear ring is combined with the first-gear combination gear; when the rear planet row gear ring moves to the position where the second-gear combination gear is located, the rear planet row gear ringis combined with the second-gear combination gear. According to the technical scheme of the invention, under non-main working conditions of the driving motor, the rear planet row gear ring is combined with the second-gear combination gear, the speed ratio of the driving motor to the input end of the axle is reduced, the driving motor with the lower rotating speed can be selected, the rotating speed corresponding to the high-efficiency area of the driving motor is reduced, and the rotating speed of the driving motor can be located in the high-efficiency area of the driving motor.
本申请公开了一种驱动电机的控制方法、相关装置及相关系统,该装置包括:拨头能够沿第一导轨水平移动,且通过拨叉与后行星排齿圈相连,后行星排齿圈能够跟随拨头移动;一档结合齿轮与壳体连接,二档结合齿轮与行星架连接;其中,后行星排齿圈移动至一档结合齿轮所在位置时,后行星排齿圈与一档结合齿轮相结合;后行星排齿圈移动至二档结合齿轮所在位置时,后行星排齿圈与二档结合齿轮相结合。本申请能够实现在驱动电机的非主要工作工况时,使后行星排齿圈与二档结合齿轮相结合,降低驱动电机与车桥输入端的速比,能够选用转速更低的驱动电机,降低驱动电机的高效区对应转速,使得驱动电机的转速能处于驱动电机的高效区内。
