The invention provides a hill-holding control method and device for an electric vehicle, a storage medium and a motor controller, and the method comprises the steps: controlling the output torque of a motor of the electric vehicle to be increased from zero when the first hill-holding control is executed after the electric vehicle enters a hill-holding state; after the electric vehicle is stably parked and maintained for a first preset time, the electric vehicle is controlled to exit the slope parking state, and the output torque of a motor of the electric vehicle is controlled to be reduced to a preset torque; and after the output torque of a motor of the electric vehicle is controlled to be reduced to a preset torque and maintained for a second preset time, continuous hill-holding control is executed based on the preset torque, and the continuous hill-holding control comprises more than one time of hill-holding control. According to the scheme provided by the invention, the temperature rise of the motor and the motor controller in the hill-holding process can be effectively delayed, the shaking in the hill-holding process is reduced or eliminated, and the hill-holding time is prolonged.

    本发明提供一种电动车辆的驻坡控制方法、装置、存储介质及电机控制器,所述方法包括:在所述电动车辆进入驻坡状态后,在执行第一次驻坡控制时,控制所述电动车辆的电机的输出扭矩从零开始增加;在驻稳并维持第一预设时间后,控制所述电动车辆退出驻坡状态,并控制所述电动车辆的电机的输出扭矩降低至预设扭矩;控制所述电动车辆的电机的输出扭矩降低至预设扭矩并维持第二预设时间后,基于所述预设扭矩执行连续驻坡控制,其中,所述连续驻坡控制包括一次以上驻坡控制。本发明提供的方案能够有效延缓驻坡过程中电机和电机控制器的温升,减小或消除驻坡过程中的抖动,延长驻坡时间。
