The embodiment of the invention provides a method and device for determining the available torque of a motor, a vehicle and a storage medium. The method comprises the steps that the current working torque of the motor is obtained; determining a current energy pool of the motor according to the working torque and a preset torque threshold value; the value of the energy pool is positively correlated with the surplus degree of the torque of the motor; determining available torque of the motor according to the current energy pool; wherein the available torque is the upper limit of the working torque. The energy pool concept is introduced to digitalize the surplus degree of the motor torque, and then the available torque is determined according to the current energy pool, so that when the working torque changes, the surplus degree of the torque changes along with the change of the working torque, and the available torque also dynamically changes along with the surplus degree of the torque, and therefore, real-time active regulation and control of the available torque can be realized; and the method has high adaptability to the real-time working condition of the motor.

    本申请实施例提供一种电机可用扭矩的确定方法、装置、车辆及存储介质,所述方法包括:获取电机当前的工作扭矩;根据工作扭矩与预设的扭矩阈值,确定电机当前的能量池;能量池的取值与电机的扭矩的盈余程度正相关;根据当前的能量池,确定电机的可用扭矩;其中,可用扭矩为工作扭矩的上限。通过引入能量池概念来数值化电机扭矩的盈余程度,继而根据当前的能量池来确定可用扭矩,使得当工作扭矩变化时,扭矩的盈余程度随之变化,可用扭矩也跟随着扭矩的盈余程度动态变化,从而实现了对可用扭矩实时地主动调控,对电机的实时工况具有较强的适应性。
