The embodiment of the invention provides a control method and device of a vehicle motor, a storage medium and electronic equipment, the vehicle motor comprises a shell, an inner rotor and an outer rotor are arranged in the shell, the inner rotor and the outer rotor are rotatably connected with the shell, and the inner rotor is installed in the outer rotor and outputs power through an inner rotor output shaft. An iron core winding is arranged on the inner side of the outer rotor, an outer rotor output shaft of the outer rotor is connected with a brake, and the control method comprises the steps that in response to a fault signal or an output voltage signal of a preset power device, control current is controlled to be input into the brake so that the outer rotor can be accelerated from a static state based on preset acceleration; the inner rotor is controlled to decelerate based on the predetermined deceleration. When the motor controller breaks down due to various reasons, main power devices are damaged or cannot be controlled and the motor is still in a power-on state, the outer rotor is controlled to idle and accelerate, the inner rotor is controlled to decelerate under the action of electromagnetic force, the electric automobile can be rapidly and stably parked, and the safety of the automobile, a driver and passengers is guaranteed.
本公开实施例提供车用电动机的控制方法、装置、存储介质及电子设备,车用电动机包括外壳,外壳内设置内转子和外转子,内转子和外转子与外壳可转动连接,内转子安装于外转子内并通过内转子输出轴输出动力,外转子的内侧设置铁芯绕组,外转子的外转子输出轴与制动器连接,控制方法包括响应于故障信号或者预定功率器件的输出电压信号,控制向制动器输入控制电流以使得外转子从静止状态基于预定加速度加速;控制内转子基于预定减速度减速。本公开在当电机控制器因各种原因发生故障、主要功率器件损坏或者不可控制且电动机还在通电状态下时,控制外转子空转加速,控制内转子在电磁力作用下减速,使电动汽车能够快速平稳停车,保障车辆和驾乘人员安全。
