Coordinated control of AFS and ESP based on fuzzy logic method

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.

Review of Powertrain Mode Transition Control Strategies for Hybrid Electric Vehicles

The current power train control strategies of hybrid electric vehicles focus on two issues: steady control problem, dynamic control problem. The former problem belongs to energy management strategy whose aim is to improve fuel economy while also attempting to minimize emissions. The latter problem refers to implement an optical control for power train components to satisfy the drivers power demand and ensure smooth power transfer. This paper gives an overview of dynamic control problem for HEV which focus on dynamic coordinated control strategies for HEV in mode transition.

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

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.
