The concept of intelligent tires has drawn attention researchers in the areas autonomous driving, advanced vehicle control, and artificial intelligence. focus this paper is on application machine learning techniques to tire force estimation. We present an system with a tri-axial acceleration sensor, which installed onto inner liner tire, Neural Network for real-time processing sensor data. acce...

A nonlinear model consisting “yaw, roll, longitudinal, lateral and pitch” has been developed in which, tire and suspension characteristics have been considered. Tire model is based on the elliptic concept and tire Calspan data. According to this tire model, cornering force and aligning moment are computed as a function of slip and camber (inclination) angles, normal load, tire adhesion characte...

Tires are a key sub-system of vehicles that have a big responsibility for comfort, fuel consumption and traffic safety. However, current tires are just passive rubber elements which do not contribute actively to improve the driving experience or vehicle safety. The lack of information from the tire during driving gives cause for developing an intelligent tire. Therefore, the aim of the intellig...

In-situ sensing the tire–road interactions such as local contact friction force distributions provides crucial information for building accurate friction force models for vehicle safety control. In this paper, we report the development of an embedded, flexible local force sensor for measuring the tire local friction forces and their distributions. A new pressuresensitive, electric conductive ru...

In this paper, we are interested in developing a robust tire-force estimator for heavy duty vehicles. We use a combined model of the articulated vehicle: a yaw plane model for the chassis motion and a vertical plane model for the axles. In the proposed method, we make use of the on-board available sensors to which are added lowcost sensors. In order to optimize the sensors configuration, a robu...

The United States Army began developing Unmanned Ground Vehicles (UGV) in the early 1900’s. Concurrently, researchers developed and enhanced passenger and commercial ground vehicles. Although significant progress has been made for improving vehicle mobility for all ground vehicles throughout the past century, mobility has lacked a concise mutually agreed definition and analytical standardized c...

The interaction between the tire and road has long been of interest for vehicle dynamic simulation. A planar tire model is developed to capture the tire circumferential displacements and calculate the spindle force according to the tire shape. The tire is discretized into segments and Hamilton’s principle is used to derive the model mathematical expression. It is shown that the static constrain...
