Tire Performance Estimation Under Combined Slip and Empirical Parametrization of the Tire Rut on Dry Sand
… navigation of vehicles across different types of terrain like soil, mud, and snow. As the properties of the terrain heavily influence the interaction with the tire, it is necessary to characterize the terrain from a tire performance and vehicle mobility perspective. Failure to properly understand …
