Abstract
The use of combined Direct Yaw-moment Control (DYC) with Active Front Steering (AFS) control to improve vehicle handling and stability is proposed. To improve the response of yaw rate, the strategy of sliding mode theory is employed for AFS controller. Basing on the optimal control theory, the DYC controller is designed. The DYC controller makes the vehicle follow the desired dynamic model by sideslip angle regulating feed-forward and the state feedback of both yaw rate and sideslip angle. The effect of combination control system on the vehicle handling and stability is studied through a open loop computer simulation of the two degrees of freedom linear vehicle model. The simulation results show that the combination of both DYC controller and AFS controller can effectively control the sideslip angle and yaw rate synchronously, achieve good transient and steady response, lighten the burden of the driver and improve vehicle handling and stability. Especially a good response can still be achieved at a high speed, which is good for improving the security of driving.
