Empirical Analysis of Pneumatic Tire Friction on Ice
Pneumatic tire friction on ice is an under-researched area of tire mechanics. This study covers the design and analysis of a series of pneumatic tire tests on a flat-level ice road surface. The terramechanics rig of the Advanced Vehicle Dynamics Lab (AVDL) is a single-wheel test rig that allows for …

Modeling and performance analysis of ABS systems with nonlinear control
… the slip values are iterated from a nonlinear tire model based on the Magic Formula. Simulations of hard braking and steering maneuvers are conducted using the nonlinear Yaw-plane Four-wheel steering vehicle model with Limited Roll motion (YFLR) incorporating the nonlinear Magic Formula tire …

Lateral Tracking and Stability Control for Automated Vehicles
… scenarios. A Modified-LuGre type dynamic tire model is proposed and used in the design of direct yaw moment control. This thesis solves the problem of optimal usage of tire traction in the application of vehicle stability control by using the 2-D Modified LuGre tire model. Since the model …

Optimal planning and control for hazard avoidance of front-wheel steered ground vehicles
… in which constrained dynamic quantities, such as friction circle utilization, are minimized, while ensuring a minimum clearance from hazards. These optimal trajectories can be computed numerically, though real-time computation requires simple models and constraints. To simplify the computation of …

Multi-Length Scale Modeling of Rubber Tribology For Tire Application
Tire, or in its primitive form, Wheel, an important invention for the transportation sector, has evolved from a circular block of hard and durable material to one of the most complex and influential components of an automobile. It is the only means of contact between the vehicle and the road and is …

Experimental Characterization and Modeling of Tire-Ice Interface
Tire parameters play a very important role in tire performance. Depending on the driving conditions for which a given tire is designed, its parameters must be chosen appropriately (e.g., the radius of the tire, the width of the tire, material properties of different sections). Among tire …

Analytical Modeling for Sliding Friction of Rubber-Road Contact
Rubber friction is an important aspect to tire engineers, material developers and pavement engineers because of its importance in the estimation of forces generated at the contact, which further helps in optimizing tire and vehicle performances, and to estimate tire wear. It mainly depends on the …

Tire-Road Friction Coefficient Estimation Using a Multi-scale, Physics-based Model
The interaction between a tire and road surface is of critical importance as the motion of a car in both transient and steady-state maneuvers is predicated on the friction forces generated at the tire-road interface. A general method for predicting friction coefficients for an arbitrary asphalt …
