The invention provides an electric vehicle motor torque control method, a storage medium and electronic equipment. The control method comprises the following steps: responding to a torque switching control signal, determining a target torque according to a driving state signal of an electric vehicle, determining the torque change amount according to the target torque and the current torque, obtaining the torque adjustment time and the corresponding relation between the torque change rate and the time according to the driving state and the torque change amount, and therefore obtaining the corresponding relation between the motor torque and the time, and controlling the motor torque according to the corresponding relation between the motor torque and the time. According to the scheme, the specific position of the torque zero point is not concerned, calculation amount is greatly reduced, due to the fact that the corresponding relation between the motor torque and the time in the whole process from the current torque to the target torque is directly obtained through the scheme and used for controlling motor torque output, overall planning is conducted in the motor control process, andcompared with the scheme of only paying attention to zero-point torque change control, the better anti-shaking effect is achieved.
本发明提供一种电动汽车电机扭矩控制方法、存储介质和电子设备,其方法能在响应到扭矩切换控制信号后,根据电动汽车的行驶状态信号确定出目标扭矩,根据目标扭矩和当前扭矩确定扭矩变化量,根据行驶状态以及扭矩变化量得到扭矩调整时间,以及扭矩变化率与时间的对应关系,从而能够得到电机扭矩与时间的对应关系,根据所述电机扭矩与时间的对应关系对电机扭矩进行控制。以上方案,无需关注扭矩零点的具体位置,大大减少了运算量,并且由于上述方案直接得到当前扭矩到目标扭矩整个过程中电机扭矩与时间的对应关系,以用于控制电机扭矩输出,从而在电机控制过程中进行了整体规划,相比于仅关注零点扭矩变化控制的方案来说具有更好的防抖动效果。
