“…In this plot, the strain levels outside the contact patch have been moved to the zero line, so the curves can be easily compared. In practice, the strain offset in the vertical axis of the plot (outside the contact patch) is associated with inflation pressure [34]. Here, the offsets have been subtracted to make up for minor differences in pressure.…”

With the recent advances in autonomous vehicles, there is an increasing need for sensors that can help monitor tire–road conditions and the forces that are applied to the tire. The footprint area of a tire that makes direct contact with the road surface, known as the contact patch, is a key parameter for determining a vehicle’s effectiveness in accelerating, braking, and steering at various velocities. Road unevenness from features such as potholes and cracks results in large fluctuations in the contact patch surface area. Such conditions can eventually require the driver to perform driving maneuvers unorthodox to normal traffic patterns, such as excessive pedal depressions or large steering inputs, which can escalate to hazards such as the loss of control or impact. The integration of sensors into the inner liner of a tire has proven to be a promising method for extracting real-time tire-to-road contact patch interface data. In this research, a tire model is developed using Abaqus/CAE and analyzed using Abaqus/Explicit to study the nonlinear behavior of a rolling tire. Strain variations are investigated at the contact patch in three major longitudinal slip driving scenarios, including acceleration, braking, and free-rolling. Multiple vertical loading conditions on the tire are applied and studied. An intelligent tire prototype called KU-iTire is developed and tested to validate the strain results obtained from the simulations. Similar operating and loading conditions are applied to the physical prototype and the simulation model such that valid comparisons can be made. The experimental investigation focuses on the effectiveness of providing usable and reliable tire-to-road contact patch strain variation data under several longitudinal slip operating conditions. In this research, a correlation between FEA and experimental testing was observed between strain shape for free-rolling, acceleration, and braking conditions. A relationship between peak longitudinal strain and vertical load in free-rolling driving conditions was also observed and a correlation was observed between FEA and physical testing.

Run-flat tires are an important solution to solve the traffic accidents of tire blowout and the inserts supporting run-flat tire (ISRFT) can effectively solve the problem of zero-pressure driving after the tire blowout. Since the characteristics of vehicles equipped with this run-flat tire after tire blowout is different from that of normal tires, a reasonable tire model is required to develop the dynamic response characteristics. In this paper, the theoretical analysis of the zero-pressure rolling for the inserts supporting run-flat tire was firstly carried out, and steady-state mechanical characteristics tests were conducted to obtain the mechanical characteristics. Secondly, a dynamics model based on the UniTire model was developed for inserts supporting run-flat with the consideration of camber angle.Finally, three sets of typical working conditions were selected to compare the effect of different camber angles on the tire blowout parameters of vehicles equipped with inserts supporting run-flat tire and normal tire (NT), which proved the superiority characteristics of inserts supporting run-flat tire. This study provides a basis for improving the autonomous characteristics of vehicles.

<div>To investigate the effect of a tire blowout (TBO) on the dynamics of the vehicle comprehensively, a three-dimensional full-vehicle multibody mathematical model is developed and integrated with the nonlinear Dugoff’s tire model. In order to ensure the validity of the developed model, a series of standard maneuvers is carried out and the resulting response is verified using the high-fidelity MSC Adams package. Consequently, the in-plane, as well as out-of-plane dynamics of the vehicle, is extensively examined through a sequence of TBO scenarios with various blown tires and during both rectilinear and curvilinear motion. Moreover, the different possible inputs from the driver, the road bank angle, and the antiroll bar have been accounted for. The results show that the dynamic behavior of the vehicle is tremendously affected both in-plane and out-of-plane and its directional stability is degraded. It has been also found that a vehicle subjected to a TBO accident is prone to a fatal rollover accident due to the excessive lateral acceleration triggered by the TBO. Furthermore, the reaction from the driver plays a crucial role in stabilizing/destabilizing the vehicle following a TBO.</div>
