YRSRA: Yaw and Roll Stable Region Analytics for Ground Vehicle System

This article presents a software tool YRSRA for calculating both the yaw and roll stable region for ground vehicle system. Firstly, the iterative model of yaw rate and slip angle is constructed through deducing the two-degree-of-freedom vehicle dynamics. Secondly, the load transfer ratio (LTR) is coded with given yaw rate and slip angle. Thirdly, several Illustrative examples are depicted, such as variation of steer angle, road adhesion coefficient and vehicle speed. The software features an easy to generate yaw and roll stability region by on-demand configuring vehicle parameters, but can also be scripted and used as a library.
