The invention discloses a twist clearing slope control method and device, a vehicle and a storage medium. The untwisting slope control method comprises the steps that when the whole electric automobile is in a gear shifting untwisting stage at present, motor demand torque is controlled to be reset at a first untwisting slope, then the current motor rotating speed is obtained in real time, and the motor rotating speed change rate corresponding to the current motor rotating speed is determined according to the current motor rotating speed; and determining a slope adjustment coefficient according to the motor rotating speed change rate, and determining a second untwisting slope according to the slope adjustment coefficient and the first untwisting slope so as to control the motor demand torque to be reset at the second untwisting slope. According to the method, self-adaptive adjustment of the gear shifting clear-twisting slope is achieved, the clear-twisting slope is automatically corrected when it is monitored that the motor has the overspeed risk, the whole vehicle performance is improved, and the fault rate is reduced.

    本发明公开了一种清扭斜率控制方法、装置、车辆及存储介质。该清扭斜率控制方法包括:在当前电动汽车整车处于换挡清扭阶段时,控制电机需求扭矩以第一清扭斜率清零后,实时获取当前电机转速,并根据所述当前电机转速确定与其对应的电机转速变化率;根据所述电机转速变化率确定斜率调整系数,并根据所述斜率调整系数和所述第一清扭斜率确定第二清扭斜率,以控制电机需求扭矩以所述第二清扭斜率清零。本发明实现对换挡清扭斜率自适应调整,并在监测到电机有超速风险时自动修正清扭斜率,提升整车性能,降低故障率。
