In order to set up a vehicle lateral controller for steering automation under the project ADVANCE-F, the frequency-shaped linear quadratic control theory is utilised to design the system for meeting requirements involved in tracking precision, robustness and ride quality by properly choosing the weighting factors. The final controller is composed of a full state feedback regulator with an observer. The simulation results reveal that the controller performs satisfactorily under a variety of situations including wind gust disturbance, transition curve and man-machine switching in a wide speed range from 0 kph to 120 kph.
