“…With the development of automotive technology, more and more tire behavior studies have been carried out to further improve the controllability of the vehicle and the predictability of its behavior, which improves the dynamic safety [1] . The accuracy of the simulation results obtained from the vehicle model depends largely on the accuracy of the tire model used [3,4,5] . With the continuous in-depth study of tire-road contact mechanism, scholars have studied a variety of different types of tire models, laying the foundation for tire mechanics research [6] .…”

In the study of vehicle dynamics, the accurate description of tire mechanical characteristics is the basis and key of vehicle dynamics simulation. An innovative tire model is proposed based on fuzzy algorithm and a sinusoidal membership function is used to design fuzzy rules. In order to ensure the accuracy of tire behavior calculation, this model is driven by a small amount of experimental data of tire mechanical characteristics. This tire model consists of four layers of fuzzy systems, each of which has a knowledge base. The data in knowledge base I is obtained by experiments, and the data of knowledge base II is computed by the upper system, and so is the later system. Then, the input signal, the change rate of side slip angle and slip rate, is considered to improve the calculation accuracy of the model. The proposed fuzzy tire model can accurately predict the longitudinal force, lateral force and self-aligning torque of the tire under unknown conditions. Finally, by comparing the fuzzy tire model with the experimental data, it is found that the maximum RRMSE (Relative Root Mean Square Error) value is not more than 0.14. It is proved that the model can accurately describe the tire mechanical characteristics under combined conditions.

“…The cornering stiffness is influenced by the tire pressure greatly. The cornering stiffness of the front and rear tires determines the steering behavior directly [27,28]. In this consideration, the tire pressure has something to do with the active safety systems, such as ESP.…”

An intelligent tire uses sensors to dynamically acquire or monitor its state. It plays a critical role in safety and maneuverability. Tire pressure is one of the most important status parameters of a tire; it influences vehicle performance in several important ways. In this paper, we propose a tire-pressure identification scheme using an intelligent tire with 3-axis accelerometers. As the primary sensing system, the accelerometers can continuously and accurately detect tire pressure with less electronic equipment mounted in the tire. To identify tire pressure in real time during routine driving, we first developed a prototype for the intelligent tire with three 3-axis accelerometers, and carried out data-acquisition tests under different tire pressures. Then we filtered the data and concentrated on the vibration acceleration of the rim in the circumferential direction. After analysis, we established the relationship between tire pressure and characteristic frequency of the rim. Finally, we verified our identification scheme with actual vehicle data at different tire pressures. The results confirm that the identified tire pressure is very close to the actual value.

An experimental and simulation study on static tire enveloping stiffness 1. Introduction Tires are the only component of a car in contact with the ground, and the mechanical performance of the tire directly affects the comprehensive performance in terms of the car's handling stability and comfort. Enhancing the mechanical properties of tires can greatly improve the safety and stability of the vehicle. Tire stiffness is an indispensable part of the mechanical analysis of tires, and it is divided into lateral stiffness, longitudinal stiffness, torsional stiffness, radial stiffness, and enveloping stiffness. The enveloping stiffness reflects the tolerance of the tire to uneven surfaces, stones, and potholes. The enveloping stiffness of a tire will directly affect the comfort of the vehicle on the road. Many studies (Zhou et al.,2009) have been performed on the enveloping stiffness with small bumps and quasi-static conditions used finite element software to simulate the stiffness characteristics of a tire, the bump width was 10 mm, and the pressure was 0.2 MPa. The deformation contour and displacement load curves of the tire were obtained. The relationship between the rise heights of the bumps and load was basically consistent with the experimental values. Some studies (Li et al.,2019) based on the static enveloping characteristics of tires used finite element software to simulate the rolling conditions of tires under different tire pressures and loads and low-speed rolling over a bulge. They found that at low speeds, the tire pressure and tire enveloping stiffness had a significant influence on the dynamic enveloping characteristics of the tire. Furthermore, the model that best matched the experimental data was composed of beam elements with a softening basis. The model was used to calculate the radial stiffness of the tire instead of the sidewall stiffness and inflation pressure, after which a model of the bump and tread was added using finite element software to study the effect of the load and radial stiffness on the enveloping characteristics of the tire. Some authors (Qiu et al.,1994) assumed that the radial stiffness of the tire was nonlinear, and
