In order to better understand the hydroplaning phenomenon, local velocity measurements of water flow are performed inside tire grooves a real car rolling through puddle. Velocity fields obtained by combining refraction Particle Image Velocimetry (r-PIV) illumination, seeding fluorescent particles, and either classical two dimensional components or three stereoscopic recording arrangements. The ...

In this paper, a new multi-objective uniform-diversity genetic algorithm (MUGA) with a diversity preserving mechanism called the e-elimination algorithm is used for Pareto optimization of a fivedegree of freedom vehicle vibration model considering the five conflicting functions simultaneously. The important conflicting objective functions that have been considered in this work are, namely, seat...

In this paper, a novel vehicle dynamics controller is proposed by combining two control loops which are formed by the individually actuated wheel braking and steering regulator. The inner braking loop regulates the individual tire force generation and prevents tire force saturation with respect to tire slip. When the tire forces are regulated to operate in the linear region of their nonlinear c...

Plus-sizing in the tire industry is the growing practice of replacing a vehicle’s original equipment wheel size with a larger diameter wheel and replacing the tire with a lower aspect ratio tire of the same diameter. This practice is normally associated with aftermarket sales, and there is a growing trend for vehicle dealerships to fit these larger wheels/tires to new cars. This paper discusses...

Today safety of the human life is major concern. Nowadays about 75% of the casualties has been observed due to the accidents during transport of the vehicle. These are especially due to the flaw in the tire pressure. Tire break avoiding is very important for safe driving in superhighway. Wireless Tire Pressure Monitoring System (TPMS) is used to detect whether one or more of the vehicle’s tire ...

We propose a simple rubber friction law, which can be used, for example, in models of tire (and vehicle) dynamics. The friction law is tested by comparing numerical results to the full rubber friction theory (Persson 2006 J. Phys.: Condens. Matter 18 7789). Good agreement is found between the two theories. We describe a two-dimensional (2D) tire model which combines the rubber friction model wi...

Among the urban societal burdens rolling noise generation from tire pavement interaction and waste stand apart. Many materials can be used in pavements with comparable mechanical performance. Noise-related characteristics such as porosity, sound absorption surface texture, were measured for semi-dense low mixtures using namely: recycled concrete aggregates, crumb rubber, polyethylene terephthal...

In this paper, a control scheme for emergency braking maneuvers in automated highway systems (AHSs) and a new online identification scheme to determine the tire–road friction characteristics of the vehicle are presented. The proposed controller determines the required pressure in the master cylinder of the braking system to achieve maximum deceleration during braking, based on the estimation of...
