Abstract: based on the dynamic model of vehicle suspension and steering, the relationship and harmony mechanism
between active suspension system and electric power steering were analyzed. 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.
