The embodiment of the invention provides a motor torque control method and device, electronic equipment and a storage medium. The method comprises the steps that firstly, whether the current gear state of a vehicle is matched with the preset gear state or not is judged; when the current gear state is matched with the preset gear state, a motor output torque slope limit value is determined according to the current vehicle speed of the vehicle and a first torque slope table; and finally, controlling the output torque value of the motor according to the motor output torque slope limit value. It can be understood that the first torque slope table is used for representing the corresponding relation between the vehicle speed and the maximum output torque slope of the motor in the zero-crossing jumping process of the output torque value of the motor, so that the torque slope limiting value better conforming to the current working condition can be determined according to the first torque slope table, and then the vehicle running smoothness under the special working condition is improved; and finally, the power performance of the vehicle and the user experience are improved.

    本申请实施例提供了一种电机扭矩的控制方法、装置、电子设备及存储介质。所述方法包括:首先判断车辆的当前档位状态与预设档位状态是否匹配;当当前档位状态与预设档位状态匹配时,根据车辆的当前车速以及第一扭矩斜率表,确定电机输出扭矩斜率限值;最后根据电机输出扭矩斜率限值,控制电机的输出扭矩值。可理解,由于第一扭矩斜率表用于表征电机输出扭矩值过零跳变过程中,车速与电机最大输出扭矩斜率的对应关系,因此根据第一扭矩斜率表可以确定出更加符合当前工况的扭矩斜率限值,进而提高了特殊工况下车辆行驶的平顺性,最终提高了车辆的动力性能以及用户体验。
