The invention relates to the technical field of vehicles, in particular to a vehicle driving motor torque control method and device, a vehicle and a storage medium, and the method comprises the steps that when it is detected that the vehicle is in a driving motor protection working condition, the balance power of a driving motor is determined according to the current temperature of the driving motor of the vehicle and the peak power of the motor; the current temperature and the basic energy of the driving motor are utilized to determine the heating energy and the cooling energy of the driving motor, the motor limiting power of the driving motor is determined according to the balance power, the heating energy and the cooling energy, and the target motor limiting torque of the driving motor is obtained through the motor limiting power and the actual rotating speed of the driving motor; therefore, the driving motor is controlled to output torque. Therefore, the problems that after the temperature of the motor rises, the external characteristic torque of the motor is limited, the actual driving working condition of the vehicle cannot be combined, the utilization rate of the peak torque of the motor and the power of the motor is reduced, and the applicability of motor torque control is reduced in the prior art are solved.

    本申请涉及车辆技术领域,特别涉及一种车辆驱动电机扭矩控制的方法、装置、车辆及存储介质,其中,方法包括:在检测到车辆处于驱动电机保护工况的情况下,根据车辆的驱动电机的当前温度和电机峰值功率确定驱动电机的平衡功率;利用当前温度和驱动电机的基础能量,确定驱动电机的升温能量和冷却能量,并根据平衡功率、升温能量和冷却能量确定驱动电机的电机限制功率,利用电机限制功率和驱动电机的实际转速获得驱动电机的目标电机限制扭矩,以控制驱动电机输出扭矩。由此,解决了相关技术中在电机温度上升后,对电机外特性扭矩进行限制,无法结合车辆的实际行驶工况,造成电机峰值扭矩和电机功率的使用率下降,降低电机扭矩控制的适用性的问题。
