The invention provides a motor control method and device, a vehicle and a storage medium, and relates to the technical field of vehicles. The method comprises the steps that when operation parameters of a power assembly of the new energy vehicle meet preset torque limiting conditions, a torque limiting request about a motor of the power assembly is generated; and performing torque reduction control on the torque of the motor according to the torque limiting request. When the operation parameters of the power assembly of the new energy vehicle meet the preset torque limiting condition, the torque limiting request is generated, so that stable, orderly and effective control over the motor is achieved; according to the torque limiting request, torque reduction control is carried out on the torque of the motor, so that the mechanical load of the motor on a power assembly is reduced by correspondingly reducing the torque output of the motor, and the situations of overload, overheating and the like caused by overload operation of related parts due to the fact that the motor keeps the current torque or the torque continues to be increased are avoided; therefore, the safety, reliability and the like of the power assembly and the vehicle operation are ensured.

    本发明提供了一种电机控制方法、装置、车辆及存储介质,涉及车辆技术领域。该方法包括:当新能源车辆的动力总成的运行参数满足预设扭矩限制条件时,生成关于所述动力总成的电机的扭矩限制请求;根据所述扭矩限制请求,对所述电机的扭矩进行降扭控制。本发明在新能源车辆的动力总成的运行参数满足预设扭矩限制条件时,生成扭矩限制请求,以便实现对电机的稳定、有序且有效的控制;根据扭矩限制请求,对电机的扭矩进行降扭控制,以通过相应降低电机的扭矩输出,来减少电机对动力总成的机械负载,避免电机保持当前扭矩或扭矩继续增大导致相关部件超负荷运行而发生过载、过热等情况,从而保证动力总成及车辆运行的安全性、可靠性等。
