Electric driving assembly, control method and device of electric driving assembly and vehicle

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 tha
