The invention provides a torque control method and device of a vehicle, the vehicle and a storage medium, and belongs to the technical field of automobiles. The method comprises the steps that when a torque reduction request is received, based on torque information of the vehicle, a motor request torque original value and a motor compensation request torque of the vehicle are determined, the motor compensation request torque is the torque needing to be output by the motor under the condition that torque assistance is carried out through the motor, and the motor request torque original value is the torque value allowed to be output by the motor at present; determining a target torque compensation mode according to the motor request torque original value and the motor compensation request torque; and controlling the torque output of the vehicle based on the target torque compensation mode. Therefore, the torque reduction requirement is met by compensating the torque, the problem that the vehicle responds to the torque request delay is solved, the torque of the vehicle can be reduced in time, the running stability of the vehicle is guaranteed, and the driving experience is optimized.

    本申请提供了一种车辆的扭矩控制方法、装置、车辆和存储介质,属于汽车技术领域,该方法包括:当接收到降扭请求时,基于车辆的扭矩信息,确定该车辆的电机请求扭矩原始值和电机补偿请求扭矩,该电机补偿请求扭矩为通过电机进行扭矩助力的情况下电机需要输出的扭矩,该电机请求扭矩原始值为电机当前允许输出的扭矩值;根据该电机请求扭矩原始值和电机补偿请求扭矩确定目标扭矩补偿方式;基于该目标扭矩补偿方式,控制该车辆的扭矩输出。这样通过补偿扭矩来实现降扭的需求,从而防止车辆响应扭矩请求延迟的问题,使车辆能够及时降扭,从而保证了车辆行驶的平稳性,优化了驾驶体验。
