Using a three-degree-of-freedom vehicle model (side-slip, yaw and roll degrees of freedom) and a nonlinear, saturating tire model, the behavior of a typcial exemplar vehicle (1986 Dogdge Lancer Turbo) was simulated. Steady state performance was examined through simulating a skidpad lateral accleration maneuver. A lane change maneuver was used to represent transient performance characteristics. A few simple experiments were conducted with the exemplar vehicle to estalbish parameters and verify some performance properties. Results of both stady state and transient simulations showed that four-wheel steer offers little or no demonstrated performance advantages over two-wheel steer.
