Integrated control of active front steering and semi-active suspension based on fuzzy logic method

Abstract

In this paper, an integrated vehicle dynamic control system of AFS/SAS is proposed to improve vehicle handling and ride performance. The SMC methodology which is deduced form the linear 2DOF vehicle model is used to design the AFS subsystem controller. Fuzzy logic control strategy is presented to control the integrated system. The simulation results show that the integrated control system can obviously improve vehicle maneuverability and ride quality much more than the individual control.
