Abstract

In order to improve the maneuverability and stability of a certain type of multi-axle special vehicle under low adhesion coefficient and high-speed conditions, an active steering controller is designed with this type of multi-axle special vehicle as the research object. Firstly, the dynamic model of this type of special vehicle is built based on Trucksim, and the accuracy of the model is verified by real vehicle experiments, which lays a foundation for the research on active steering control. Then, an active steering controller is designed based on the Ackerman steering principle with the zero centroid slip angle as the control objective. Finally, the model of the controller is built through simulink, and the cosimulation with the vehicle dynamics model of Trucksim is carried out to verify the designed active steering controller. The simulation results show that the designed active steering controller has an ideal control effect on the roll stability and handling stability of the vehicle under high speed conditions and low adhesion road coefficient.
