A new method was studied for directional stability improvement of articulated vehicles consisting of a tractor pulling multiple semi-trailers by introducing the all-wheel harmonized steering system. A series of simulations were used. Based on the state equations a servo control system was built to make each vehicle follow its individual target precisely. A state variables feedback system was established to enable the optimum steering of all wheels. Potential vehicle motion at entering into circular turning, lane changing and external disturbance with a series of simulations based on the above system were studied. It was clearly shown that all wheel steering is effective for directional stability. An observer was established for estimating all state values by measuring relative yawing angular velocity of a trailer only. The effectiveness of the observer was confirmed by a series of simulations.
