The embodiment of the invention provides an electric driving assembly, a control method and device of the electric driving assembly and a vehicle. The electric driving assembly comprises a driving motor, a controller, a connecting rod and a frequency characteristic regulator; the controller and the connecting rod are independently fixed to an outer shell of the driving motor. The frequency characteristic regulator comprises a body part and a frequency regulating part; the body part is fixed on the connecting rod, and the frequency adjusting part is mounted on the body part; the working end of the frequency adjusting part abuts against the cover plate of the controller, and the resonant frequency of the controller is changed by changing the pressure applied to the cover plate. Under the condition that the main-order excitation frequency of the driving motor is determined, the resonant frequency of the controller can be changed by adaptively adjusting the pressure applied by the frequency adjusting part, so that the resonant frequency of the controller and the main-order excitation frequency of the driving motor are staggered; the problems of controller resonance caused by the fact that the main-order excitation frequency is the same as or close to the resonance frequency and howling caused by resonance are avoided.
本公开实施例提供一种电动驱动总成、电动驱动总成的控制方法和装置、车辆。电动驱动总成包括驱动电机、控制器、连杆和频率特征调节器;控制器和连杆分别独立地固定在驱动电机的外壳体上;频率特征调节器包括本体部和频率调节部;本体部固定在连杆上,频率调节部安装在本体部上;频率调节部的工作端抵靠在控制器的盖板上,通过改变施加在盖板上的压力而改变控制器的共振频率。在确定驱动电机的主阶次激励频率的情况下,适应性调整频率调节部施加的压力,可以改变控制器的共振频率,进而使得控制器的共振频率与驱动电机的主阶次激励频率错频,避免因为主阶次激励频率与共振频率相同或者接近而引起控制器共振以及因为共振产生的啸叫问题。
