| ABSTRACT |
|
In this paper, an active front steering (AFS) controller with a new variable steering ratio (VSR) map is proposed
to enhance the vehicle stability and consider the driver’s steering comfort. The properties of the steering sensitivity and the
yaw rate gain are investigated and utilized to construct a 3D VSR map in terms of the steering wheel angle and the longitudinal
vehicle velocity. Based on this 3D VSR map, the AFS controller is designed by adopting the model predictive control (MPC)
approach. An optimum solution of the MPC controller is determined by taking into account the AFS actuator limits. The
proposed algorithm is validated in simulations by using the commercial software, CarSim and MATLAB/Simulink. |
