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 ...

An original method for the real-time estimation of the roll angle using low-cost sensors in two-wheeled vehicles is proposed. The roll angle greatly affects the dynamics of singletrack vehicles and its estimation is essential in control systems such as ABS, Traction Control, as well as Curve and Collision Warning, or even active suspensions. The proposed method uses a non-linear Kalman filter, ...

In order to provide appropriate performance on potentially hazardous winter or icy road surfaces, it is common to employ specific tyres developed for such conditions. Such winter tyres may contain studs embedded in the tyre tread, or they may be studless. Additionally, it is possible to use so called all season tyres which are also fitted for winter conditions. In some northern countries, the u...
