The invention discloses an electric drive anti-shake control method and module, a vehicle and a computer storage medium. According to the method, the jitter problem in various scenes is considered. For a scene of switching working conditions, when the torque output by the motor is controlled based on the target torque, the target torque is adjusted through the specified gradient, so that the stability of the change of the torque output by the motor can be improved, and the problem of shaking in the scene can be improved. For a torque zero-crossing scene, corresponding second anti-shake torque and third anti-shake torque are set for an upward zero-crossing state and a downward zero-crossing state respectively, so that the problem of shake in the scene is solved. In addition, the method also considers the wheel speed difference anti-shake torque, so that the shake caused by the wheel speed difference can be compensated. According to the method, corresponding methods for controlling the torque output by the motor are set for the shaking problem under various working conditions, so that the accuracy of the methods can be improved, and then the anti-shaking effect can be improved.
本申请公开了一种电驱防抖控制方法、模块、车辆及计算机存储介质。该方法考虑了多种场景下的抖动问题。对于切换工况的场景,该方法在基于目标扭矩控制电机输出的扭矩时,通过指定梯度调整目标扭矩,如此可以提升电机输出的扭矩的变化的平稳性,从而可以改善在该场景下的抖动问题。对于扭矩过零的场景,该方法分别对向上过零状态以及向下过零状态设置了对应的第二防抖扭矩和第三防抖扭矩,以改善在该场景下的抖动问题。并且,该方法还考虑了轮速差防抖扭矩,从而可以补偿轮速差异引起的抖动。本申请对于多种工况下的抖动问题,分别设置了对应的控制电机输出的扭矩的方法,从而可以提升该方法的精准性,进而可以提升防抖效果。
