The invention discloses a motor rotating speed amplitude limiting control method, device and equipment and a storage medium, and the method comprises the steps that when it is determined that a vehicle is in a pure electric starting state or a rotating speed amplitude limiting control state according to preset conditions, the motor rotating speed of the vehicle is obtained, and the rotating speed difference value between the motor rotating speed and the set maximum rotating speed is determined; judging whether the vehicle has a shaking risk or not according to the rotating speed difference value; if yes, the output torque of the motor is adjusted according to the rotating speed difference value in the latest period of time. And adjusting the motor speed according to the motor speed and the output torque. After it is determined that a vehicle is in a pure electric starting state or a rotating speed amplitude limiting control state, whether the shaking risk exists currently or not is determined through the rotating speed difference value between the rotating speed of a motor and the maximum rotating speed, and when the shaking risk exists, the output torque of the motor is adjusted through the rotating speed difference value condition in the latest period of time; and the motor rotating speed is further subjected to feedback regulation, so that the motor rotating speed can be finally recovered to a safe range.

    一种电机转速限幅控制方法、装置、设备及存储介质,方法包括:根据预设条件确定车辆处于纯电起步状态或者转速限幅控制状态时,获取车辆的电机转速,并确定电机转速与设定的最大转速之间的转速差值;根据转速差值,判断车辆是否存在抖动风险;若存在,根据最近一段时间内的转速差值,调整电机的输出扭矩。根据电机转速和输出扭矩,调整电机转速。通过确定车辆处于纯电起步状态或者转速限幅控制状态之后,利用电机转速与最大转速之间的转速差值来确认当前是否存在抖动风险,存在抖动风险时,将利用最近一段时间内的转速差值情况来对电机的输出扭矩进行调整,并进一步对电机转速进行反馈调节,进而保障电机转速最终能够恢复到安全范围。
