Performance of Four-Wheel-Steering Vehicles in Lane Change Maneuvers

This study addresses the performance of four-wheel-steering vehicles in high-speed lane change maneuvers. We compare the steering commands of an experienced driver in executing high-speed lane change maneuvers in road tests with those determined via solving suitably formulated optimization problems. It turns out that the optimal control determined is qualitatively comparable to the steering commands used by experienced drivers in road tests. Hence, we can analytically compare the performance of an experienced driver in executing lane change maneuvers using different vehicles.
