Device and Method for Estimating a Current Wheel Diameter

Abstract

A device (9, 9a) for estimating a current wheel diameter of a wheel of a rail-based vehicle on a predetermined network of routes includes an interface (8) for collecting vibration data (5) of at least one wheel acting on the rail-based vehicle as an acceleration of the rail-based vehicle. The vibrations detectable using at least one wireless sensor (2a, 2b, 2c, 2d) arranged proximate the at least one wheel. A computing unit is configured for generating a predicted speed on the basis of the vibration data (5). A comparator unit is configured for estimating a wheel diameter based on differences between the predicted speed and an identified, corresponding ground truth speed (17).
