In order to study the coupling relationship of integrated system’s structure and control parameters, a combined optimize strategy to adjust parameters of two systems was proposed. The controller of active suspension system was designed using self-tuning control and the electric power steering system was designed using PID control. The simulation results show that compared with no control or single control system, integrated control can improve the controllability and stability, ride comfort, maneuverability and safety of vehicle.
