Simulation of the steering characteristics of multi-axle vehicles based on a linear two-degree-of-freedom model

With the development of intelligent and unmanned heavy-duty multi-axle vehicles, it is necessary to conduct research on vehicle lateral dynamics. By establishing a linear two-degree-of-freedom model of a multi-axle vehicle, the steady-state and transient analyses of the steering characteristics of a six-axle vehicle are performed. Simulation results qualitatively show that the use of multi-axle steering technology can effectively improve the steering maneuverability of the vehicle and provide theoretical support for controller design in the future.
