The invention relates to a motor torque control method and system, electronic equipment and a medium. The method comprises the steps that the accelerator pedal opening change rate of a driver is recognized; under the Tip in working condition, whether the accelerator pedal opening change rate exceeds a preset threshold value or not is judged, and mean filtering is executed to smooth accelerator pedal opening change; the smoothed accelerator pedal opening degree is input into the maximum torque mapping relation, and the target torque of the motor is obtained; limiting the rise rate of the motor target torque according to the current speed of the vehicle, synthesizing the actual target torque of the motor and sending the actual target torque to the controller; under the working condition of Tip out, the torque direction of the motor is judged, whether reverse torque does not appear or not is met, and the target torque decline rate of the motor is calculated and adjusted in real time; when the reverse torque exists, the motor torque reduction rate is set according to the vehicle speed, and the motor torque is gradually transited from a positive value to a negative value through smooth processing of zero crossing point transformation; and the actual target torque of the motor acts on the vehicle, and stable operation of a transmission system is achieved.

    本发明涉及一种电机扭矩控制方法、系统、电子设备及介质,该方法包括:识别驾驶员的加速踏板开度变化率;在Tip in工况下,判断加速踏板开度变化率是否超过预设阈值,执行均值滤波以平滑加速踏板开度变化;将平滑后的加速踏板开度输入到最大扭矩映射关系中,获取电机目标扭矩;根据车辆当前车速限制电机目标扭矩的上升率,合成电机实际目标扭矩并发送至控制器;在Tip out工况下,判断电机扭矩方向及是否满足无反向扭矩出现,计算并实时调整电机目标扭矩下降速率;当存在反向扭矩时,依据车速设定电机扭矩下降速率,通过平滑处理过零点转变,实现电机扭矩从正值逐渐过渡为负值;将电机实际目标扭矩作用于车辆,实现传动系的稳定运。
