The invention belongs to the technical field of automobiles, and particularly relates to a semi-active suspension hybrid ceiling-ground ceiling control method based on an improved controllable inerter. Comprising the following steps: step 1, modeling an ideal hybrid ceiling-ground shed semi-active suspension considering an inerter; 2, optimizing parameters of the ideal hybrid ceiling-ground shed semi-active suspension model considering the inerter; and step 3, determining a controllable inertia coefficient of the improved controllable inerter according to the inertia coefficient of the optimized ceiling inerter obtained in the step 2, so as to design a control strategy of the hybrid ceiling-ground ceiling semi-active suspension considering a matching relationship between a damping coefficient and the inertia coefficient. According to the method, it can be guaranteed that the vehicle keeps the optimal inertia coefficient and damping coefficient under different road conditions, vehicle body vibration of the target vehicle is effectively reduced, and the driving comfort is improved.
