The invention provides an automobile semi-active suspension damping control method. An acquisition module, a conversion module, a processing module and a control module are included. The control method comprises the following steps of S1, collecting the current sprung mass through a sensor; S2, collecting automobile speed information through a sensor; S3, respectively inputting the information into an A/D conversion module; S4, inputting the converted digital information into a control module; S5, analyzing and outputting a control signal U by the control module; and S6, inputting the control signal U into a D/A conversion module, and outputting control voltage to adjust suspension damping. The semi-active suspension damping control method has the advantages that a multi-point measurement mode is adopted, sprung mass and vehicle body speed information are collected, damping of the semi-active suspension is changed through a fuzzy control algorithm in the controller, and the comfort and safety of the suspension are effectively improved.
