The modern active systems and the advanced driver assistance systems have certainly reduced the amount of accidents. However these systems are still lacking one major information, which is the friction between the tyre-road interface. The performance of these systems could be enhanced substantially if this information was known. Rather simple methods can be used to determine the friction coeffi...

soil compaction can occur as a result of a number of factors. one of the most important factors is soil response to pressures imposed by wheels and soil engaging tools. this research investigated the effect of tyre load and inflation pressure on soil compaction-related factors. these factors include rut width, rut depth, cone index and horizontal force in different layers of soil profile. in th...

This paper introduces an improved Electronic Stability Program for cars that can deal with the sudden burst of a tyre. The Improved Electronic Stability Program (IESP) is based on a fuzzy logic algorithm. The IESP collects data from the same sensors of a standard ESP and acts on brakes/throttle with the same actuators. The IESP reads the driver steering angle and the dynamic condition of the ca...

The driving speed of modern tractors increased within last years up to 60 km/h. Together with the driving speed, the safety and comfort requirements are increasing as well. Since modern agricultural tractors still don’t have a rear axle suspension, their driving dynamics behaviour can become critical at certain situations. To be able to predict such critical situations, a multibody model of a t...

We present an application of artiicial neural networks to monitoring the tyre pressure of cars using acoustic data derived from vibrations recorded by an accelerometer. As a preprocessing step for feature extraction we perform a spectral analysis of the sound data. The components of the estimated power density spectrum are used as input patterns for the neural estimator. These patterns are used...

Abstract The noise generated by the rolling tyre contributes significantly to cars interior noise. This is caused tyre-road contact, and at low frequencies (0-500 Hz) mostly transmitted inside cockpit through structure-borne transmission path. In support of studies in this research field, an interpretative model tyre-wheel system accounting for effects induced angular speed represents a useful ...
