The invention provides a variable-parameter suspension control method and system and electronic equipment, and belongs to the field of vehicle control. The method comprises the steps that road surface unevenness excitation is obtained; determining the cut-off frequency of a filter according to road surface unevenness excitation; establishing a state equation of the suspension system; determining a frequency response function based on the state equation of the pavement unevenness excitation and suspension system; based on the road surface unevenness excitation, the filter cut-off frequency and the frequency response function, the control rate is solved so as to control the acting force applied to the automobile mass borne by the wheel by the suspension beam and the acting force applied to the wheel mass by the suspension beam. According to the invention, the balance of acceleration and dynamic stroke under different road conditions can be realized.
