This paper investigates the use of four-wheel-steering system for the control of vehicle, in the context of automatic lane-tracking. In this paper, the lane-tracking control system is designed on the basis of the four-wheel-steering automobile whose desired steering response is realized by the application of model matching control. Using simplified linear 2 degree-of-freedom bicycle model, simulation study and theoretical analysis are conducted to evaluate the lane-tracking control performance of active four-wheel-steering automobiles which have different desired steering response. A comparative study clearly reveals their advantages in lane-tracking performance.
