| Abstract(E) | Vehicle response to steering input is affected by interaction between the steering system and vehicle motion. Front-tyre lateral forces generate a restoring moment about the kingpin, which acts on the steering system and couples the steering system with vehicle motion. Previous studies have proposed steering control methods to decouple this interaction. However, a framework for incorporating the restoring moment into steering system dynamics as a steering–vehicle coupling term has not been explicitly organised. This study examines the coupled structure of a steering–vehicle system with steering control. A two-degree-of-freedom steering-system model is reduced to a one-degree-of-freedom steering-system model, and dominant poles are compared. Root loci and coefficients of the characteristic equation show that the restoring moment appears as a coupling term. The derived stability conditions clarify the roles of the restoring-moment coupling term and steering control in system stability. Incorporating the coupling term into steering-system dynamics enables vehicle-motion effects and steering control to be treated in a unified form. |
