With the advancement of vehicle chassis electrification, propulsion torque, steering angle, and suspension deformation are becoming independently adjustable, supplying the potential to further enhance the chassis dynamic performance and driving safety. The suspension geometric characteristics play a vital role due to their dominant influences on the wheel attitude and the resulting forces, especially under severe maneuvers. In this work, we propose the parametrization of independent suspension geometry based on the screw theory and extend the conventional vehicle lateral dynamic model with parameter calibration and simulation verification in a double lane-change maneuver. This study establishes a connection between the chassis structure and the actuation-level control, providing an important reference for more accurate chassis motion control and its application in assisted/autonomous driving.
