The invention discloses a semi-active suspension control method, a vehicle-mounted controller, a system, an automobile and a medium. The method comprises the steps that first detection data and second detection data collected in the vehicle driving process are acquired; performing fuzzy processing on the first detection data and the second detection data to obtain a first fuzzy state corresponding to the first detection data and a second fuzzy state corresponding to the second detection data; determining a target driving voltage according to a first fuzzy state corresponding to the first detection data and a second fuzzy state corresponding to the second detection data; and according to the target driving voltage, a piezoelectric element in the shock absorber is controlled to work. The method does not need to adopt any precise dynamic differential equation to carry out complex modeling calculation, not only can improve the efficiency of obtaining the target driving voltage, but also is easy to engineer when active control over the damping force of the shock absorber in the semi-active suspension is achieved, has a good real vehicle control effect, and is suitable for large-scale popularization and application. The control effect of the damping force of the shock absorber in the semi-active suspension can be improved.
