The use of control systems, especially vehicle dynamic control systems, is increasing at a remarkable rate. A key parameter that affects the performance of a vehicle dynamic control system is the interaction forces between the tyre and the road since these forces determine the acceleration, braking and steering properties of a car. Consequently, the accurate estimate of these forces is highly d...

Tyre bead grade wire is used for tyre making application. The wire is used as reinforcement inside the polymer of tyre. The wire is available in different size/section such as 1.6-0.80 mm thin Cu coated wire. During tyre making operation at tyre manufacturer company, wire failed frequently. In this present study, different broken/defective wire samples were collected from wire mill for detailed...

Direct tyre-road contact friction estimation is essential for future active safety systems. Friction estimation methods were proposed earlier for driving conditions in the presence of a slip angle or slip ratio. However, the estimation of friction from a freely rolling tyre is still an unsolved topic. This study uses three 3-axis accelerometers on the inner liner of a tyre to detect friction po...

ABSTRACT At final parameters and characteristics of tyre can influence several basic elements – tyre composition, sort of used fillers, caoutchouc, reinforcing materials, their construction, choice of curing process, process of stabilization, storage conditions and so on. Nowadays by motorizing development are producers specialized for tire properties parameterize. This fact is necessary to sat...

This paper investigates a low degree-of-freedom wheel model, which describes the lateral vibration of towed wheels, called the shimmy. The model takes into account the lateral deformation of the tyre and also the torsional elasticity and the damping of the steering mechanism. The lateral deformation of the wheel is modeled by the stretched-string like tyre model, which considers the relaxation ...

Many people die each year in car accidents because of damaged tyres. There are some techniques that have been suggested during the years to detect such tyres. In this paper, we suggest a new technique for detecting damaged tyres employing a standard digital camera that produces JPEG images. The camera takes pictures of the tyre and if the image size is too large, the tyre is deemed to be with a...

Heavy aircraft main landing gear tyres skid immediately after touchdown as result of the high slip ratio between the tyres and runway, which lead to tyre wear and smoke. In this paper, the tyre wear is modelled on the Archard theory using ANSYS mechanical transient, to reveal the wheel’s dynamic and the tyre tread wear. The wheel’s dynamic and the amount of wear are calculated for initially sta...

A novel model based scheme for the state estimation during anti-lock braking is presented based on a LuGre tyre model and a quarter car model. The wheel angular speed and longitudinal vehicle acceleration information are used to design a nonlinear observer based on the unscented Kalman filter theory. This nonlinear observer provides the necessary information for the anti-lock control despite th...
