N2 - This paper addresses the problem of integrated control of Electrical Power Steering System (EPS) and Active Suspension System (ASS). Through integrating EPS with ASS, a full car dynamic model is established. Based on the integrated model, a random sub-optimal control strategy based on output feedback is designed to fulfill the integrated control of both EPS and ASS. The characteristics of the integrated control system are analyzed using Mattab/Simulink and a series of comparisons are made with the system without control and the ASS-only/EPS-only system. The simulation results show that the integrated control scheme can not only enhance the steering quality, but also significantly isolate the road excitation. Moreover, the integrated control system has a great improvement on anti-roll and anti-pitch abilities. The proposed research provides a theoretical solution for simultaneously improving the multiple vehicle performance indices including maneuverability, handling stability, ride comfort, and safety.
