Vehicle Dynamics Platform, Experiments, and Modeling Aiming at Critical Maneuver Handling
For future advanced active safety systems, in road-vehicle applications, there will arise possibilities
for enhanced vehicle control systems, due to refinements in, e.g., situation awareness systems. To
fully utilize this, more extensive knowledge is required regarding the characteristics and dynamics
of vehicle models employed in these systems. Motivated by this, an evaluative study for the lateral
dynamics is performed, considering vehicle models of more simple structure. For this purpose, a
platform for vehicle dynamics studies has been developed. Experimental data, gathered with this
testbed, is then used for model parametrization, succeeded by evaluation for an evasive maneuver.
The considered model configurations are based on the single-track model, with different additional
attributes, such as tire-force saturation, tire-force lag, and roll dynamics. The results indicate that
even a basic model, such as the single-track with tire-force saturation, can describe the lateral dy-
namics surprisingly well for this critical maneuver.
