The invention relates to the technical field of vehicles, in particular to a control method, device and equipment for a preview type semi-active suspension and a storage medium, and the method comprises the steps that state information at the current moment is collected; predicting a state output vector of the semi-active suspension control system in a prediction time domain according to the state information based on a pre-established model prediction controller, and obtaining a target optimization function according to the state output vector; and according to a preset reference input vector, a control sequence meeting the target optimization function and a preset constraint condition is calculated, and a target control quantity is obtained based on the control sequence, so that the semi-active suspension control system is controlled based on the target control quantity. Therefore, the problem that the smoothness and comfort of the vehicle cannot be guaranteed due to the fact that the front road surface information is not considered in the prior art is solved, the road surface information is fused, prediction control based on road preview is achieved, and the riding comfort and the driving smoothness can be improved.
