The invention discloses a vehicle semi-active suspension damping control method, device and equipment and a medium, and relates to the technical field of vehicle control, and the method comprises the steps: building a multi-degree-of-freedom vehicle dynamics model based on the motion posture of a vehicle and in combination with the influence of each motion posture on the smoothness of the vehicle; according to the established degree-of-freedom whole vehicle dynamic model, a whole vehicle vibration equation is obtained through calculation, and according to semi-active suspension damping force output control logic, a variable damping output value is obtained through calculation; pID parameters are adjusted based on a preset intelligent algorithm, and variable damping output control is achieved through the PID controller after parameter adjustment. According to the invention, full-band adaptive correction of a semi-active suspension control strategy can be effectively solved, and the attitude stability of a vehicle body is ensured.
