Abstract :
In this paper, coordinated vehicle dynamic control system of AFS/ESP 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. The model reference adaptive algorithm is used to derive the control law for ESP controller. A fuzzy logic control strategy is presented to control the coordinated system. The simulation results show that the coordinated control system can obviously improve vehicle maneuverability and ride quality much more than the individual control.
