The difference between semi-active suspension model based on damping force and damping control is analyzed. The semi-active suspension is intrinsically nonlinear and a two-degree-of-freedom semi-active suspension model based on damping control is established. The simulation results show that the semi-active suspension has some limitations in improving vehicle performance. Finally, the evaluation method of semi-active suspension control is discussed, and the necessity of improving the evaluation method is analyzed
