Taking the control of the vehicle's active suspension as the research object, the vehicle body's vertical runout, vehicle body
pitch and roll vibration are regulated, and the SIMS strap-down inertial measurement technology is used to collect body attitude data
in real time to establish a 7-degree-of-freedom vehicle dynamic model. The large-scale system decentralized control is introduced to
decentralize the entire vehicle control into four 1?4 car body vertical control. Simulation analysis proves that the SIMS-based vehicle
active suspension control technology proposed in this paper can effectively control the body attitude change, and improve the dynamic performance of the vehicle
