This paper discusses the possibility of assessing vehicle stability by means of unconventional graphical methodologies and defining a region of stability of the vehicle, using only yaw rate, lateral acceleration and sideslip rate. The three-dimensional β-r-β˙ phase surface is investigated, relating trajectories in the r-β˙ plane to their β values. The r-β˙ phase plane is investigated for different tyre models and tyre-road friction conditions. A new stability region is proposed.

Abstract

This paper discusses the possibility of assessing vehicle stability by means of unconventional graphical methodologies and defining a region of stability of the vehicle, using only yaw rate, lateral acceleration and sideslip rate. The three-dimensional β-r-β˙ phase surface is investigated, relating trajectories in the r-β˙ plane to their β values. The r-β˙ phase plane is investigated for different tyre models and tyre-road friction conditions. A new stability region is proposed.
