| ABSTRACT |
|
This paper investigates integrated vehicle dynamics control through coordinating active aerodynamics control,
active rear steering, torque vectoring and hydraulically interconnected suspension for improving the overall vehicle
performance including handling, stability, and comfort. After developing each chassis control system, it is tested by various
manoeuvres in order to assess each subsystem. Then, a rule-based coordinate system is proposed for integrated control of the
four chassis control systems. Simulation investigation is performed to display the effectiveness of the proposed integrated
vehicle dynamics system. Results demonstrate that the proposed control scheme is able to enhance the multiple performance
indices of the vehicle including both the ride comfort, and the lateral stability, compared to the non-integrated control system. |
