In this paper, a new architecture vehicle is introduced, which is called active-steering articulated virtual rail train (ASVRT). To realize the running control of ASVRTs under virtual rail constraints, a new active-steering system including a target trajectory generator and two controllers is designed. Firstly, the ASVRT kinematic model with n-units is established. Then a target trajectory generator is addressed based on coordinate calculation, transformation, and curve fitting. Furthermore, a rear-axle steering controller is designed to realize all hinge points track on the target trajectory, and then a front-axle coordinated steering controller is designed for units 2-N to achieve coordinated movement of the train and avoid large hinge stress. Finally, a simulation model with five units is built in software ADAMS, and then the simulations are carried out under the typical rails with different speeds. The simulation results show the proposed active-steering system has good tracking control performance.
