The invention relates to the technical field of motor control, and discloses a motor rotating speed control method, device and equipment, and the method comprises the steps: detecting an opening value of a clutch; determining a motor control mode according to the opening value of the clutch; when the motor control mode is a rotating speed control mode, the rotating speed of the motor is controlled according to a target rotating speed, so that the rotating speed of the motor approaches the target rotating speed; or, when the motor control mode is a torque control mode, the minimum torque in the required torque, the rotating speed limiting torque and the clutch limiting torque is selected as the target torque, and the rotating speed of the motor is controlled according to the target torque. The rotating speed of the motor is controlled in different modes and stages by combining the opening signal of the clutch, so that the control accuracy is improved, and the passenger safety and property safety are protected.

    本发明涉及电机控制技术领域,公开了一种电机转速控制方法、装置及设备,包括:检测离合器的开度值;根据所述离合器的开度值确定电机控制模式;在所述电机控制模式为转速控制模式时,根据目标转速控制所述电机的转速,以使所述电机的转速趋近所述目标转速;或,在所述电机控制模式为扭矩控制模式时,选择需求扭矩、转速限制扭矩及离合器限制扭矩中的最小扭矩作为目标扭矩,以根据所述目标扭矩控制电机的转速。通过结合离合器开度信号,分模式分阶段控制电机的转速,提高了控制的精确度,保护了乘客安全和财产安全。
