The invention discloses a motor winding switching control method and device, a vehicle and a storage medium, and the method comprises the steps: obtaining a current torque value of a motor in response to a torque request when the motor is in a dual-winding operation state; comparing the current torque value with a single-winding constant torque value of the motor; if the current torque value is greater than the single-winding constant torque value of the motor, determining a torque reduction speed threshold value according to the current torque value; wherein the constant torque value of the single winding is the constant torque value of the single winding of the motor in the constant torque interval; and the current rotating speed corresponding to the current torque value is compared with the torque reduction speed threshold value to control the motor to keep double-winding operation, or an active torque reduction instruction is output to control the motor to be switched to single-winding operation. By applying the technical scheme of the invention, the problems of large motor torque pulsation and torque jittering during motor winding switching are solved, the torque jittering during winding switching is reduced, and the riding comfort during vehicle driving is improved.

    本申请公开了一种电机绕组切换控制方法、装置、车辆及存储介质,该方法包括:在电机处于双绕组运行状态时,响应扭矩请求,获取电机的当前扭矩值;将当前扭矩值与电机的单绕组恒扭矩值进行对比;若当前扭矩值大于电机的单绕组恒扭矩值,则根据当前扭矩值确定降扭转速阈值;其中,单绕组恒扭矩值为电机单绕组在恒扭矩区间的恒扭矩值;将当前扭矩值对应的当前转速与降扭转速阈值进行对比,以控制电机保持双绕组运行,或者输出主动降扭指令控制电机切换为单绕组运行。应用本申请的技术方案,解决了电机绕组切换时电机扭矩脉动大,存在扭矩抖动的问题,减小了绕组切换时的扭矩抖动,提升了车辆行驶时的乘坐舒适性。
