The invention relates to the technical field of vehicles, in particular to a motor power response control method and device, a vehicle and a storage medium, and the method comprises the steps that the current ODO mileage change threshold value, the current rotating speed jitter change threshold value, the current accelerator pedal opening degree and the current vehicle rotating speed of the vehicle are obtained; a first adjusting coefficient and a second adjusting coefficient are determined according to the current ODO mileage change threshold value and the rotating speed shaking change threshold value, and the current required torque is obtained according to the accelerator pedal opening signal and the vehicle rotating speed signal; and motor response time is obtained according to the first adjustment coefficient, the second adjustment coefficient and the current required torque, and motor power response is controlled according to the motor response time. Therefore, the problem that the power transmission of the electric automobile is not smooth due to abrasion and aging is solved, the smoothness and stability of the power transmission of the motor are improved by adaptively adjusting the power response of the motor, the maintenance cost is reduced, and the user experience is improved.

    本发明涉及车辆技术领域,特别涉及一种电机动力响应控制方法、装置、车辆及存储介质,其中,方法包括:获取车辆的当前ODO里程变化阈值、当前转速抖动变化阈值、当前加速踏板开度和当前车辆转速;根据当前ODO里程变化阈值和转速抖动变化阈值确定第一调节系数和第二调节系数,并根据加速踏板开度信号和车辆转速信号得到当前需求扭矩;根据第一调节系数、第二调节系数和当前需求扭矩得到电机响应时间,以根据电机响应时间对电机动力响应进行控制。由此,解决了电动汽车动力传递因磨损老化导致不平顺的问题,通过自适应调节电机动力响应,提升电机动力传递的平顺性和稳定性,降低维护成本,提升用户体验。
