A Vehicle Dynamics Model for Torque Vectoring During a Turn.

Abstract

The focus of this research work is to develop a comprehensive vehicle dynamics model which addresses the coupling between longitudinal, lateral and vertical dynamics. Besides providing information about the translational and rotational variables, both under transient and steady state condition, it also aims to track changes in Euler angles with time which are used in most of the navigation algorithms. This research work strives to be a substantial improvement over the classical and much referred Bicycle Model for lateral dynamics by addressing coupled nature of translational and rotational dynamics; includes the effect of aerodynamics; considers non–linear nature of tire mechanics; has suspension modeling; accounts for lateral and longitudinal load transfers and last but not the least is able to simulate transient dynamics too and informs about other states of vehicles assumed constant or neglected in the former model.
