The invention provides a torque control method and device, a vehicle and a readable storage medium, the method is applied to the technical field of vehicles, and the method comprises the steps that the slip rate of the vehicle is determined; under the condition that the slip rate of the vehicle is larger than the slip rate threshold value, responding to the situation that the vehicle is in the variable-speed driving state, and obtaining the rotating speed limit value of a driving motor of the vehicle, the current rotating speed of the driving motor and the current output torque of the driving motor; according to the slip rate, the rotating speed limit value and the current rotating speed of the vehicle and the current output torque of the driving motor, the target output torque of the driving motor is determined, and when the vehicle is in the accelerated driving state, the determined target output torque is smaller than the current output torque; when the vehicle is in the deceleration driving state, the determined target output torque is larger than the current output torque; and adjusting the current output torque of the driving motor to the target output torque so as to adjust the rotating speed of the driving motor. The method can prevent the vehicle from shaking and abnormal sound when the vehicle passes through the deceleration strip during acceleration/deceleration.

    本申请提供了一种扭矩控制方法、装置、车辆以及可读存储介质,该方法应用于车辆技术领域,该方法包括:确定车辆的滑移率;在车辆的滑移率大于滑移率阈值的情况下,响应于车辆处于变速行驶状态,获取车辆的驱动电机的转速限值、驱动电机的当前转速以及驱动电机的当前输出扭矩;根据车辆的滑移率、转速限值、当前转速以及驱动电机的当前输出扭矩,确定驱动电机的目标输出扭矩,当车辆处于加速行驶状态时确定的目标输出扭矩小于当前输出扭矩,当车辆处于减速行驶状态时确定的目标输出扭矩大于当前输出扭矩;将驱动电机的当前输出扭矩调整至目标输出扭矩,以调整驱动电机的转速。该方法能够在车辆加速/减速经过减速带时,避免车辆出现抖动和异响。
