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).

A method for recognizing a rail vehicle wheel as well as an arrangement for recognizing a rail vehicle wheel. A specific detection pattern of the rail vehicle wheel to be identified is ascertained using rollover signal of a rail vehicle wheel to be identified, which is ascertained with the aid of a load measuring device arranged on a rail, the rollover signal describing a time characteristic of a rail load induced by the rail vehicle wheel to be identified on the rail equipped with the load measuring device during the rollover, and the specific detection pattern comprising one or multiple identification parameter(s)/characteristic value(s) ascertained using the rollover signal. The ascertained specific detection pattern of the rail vehicle wheel to be identified is compared with one or multiple predefined reference-specific detection pattern(s) of rail vehicle wheels, and the rail vehicle wheel to be identified is identified by the comparison.

The present invention is a system and method for the control of applying lubrication to the wheels of a fleet of railed-based vehicles and the rails on which the railed-based vehicles travel. In an aspect, the wheel-rail lubrication fleet management system is configured to analyze and optimize the application of wheel/rail lubrication within a whole fleet to the best possible efficiency. In an additional aspect, the wheel-rail lubrication fleet management system is further configured to manage the noise created by the interaction between the wheels and rails of the whole fleet. In such aspects, the wheel-rail lubrication fleet management system can monitor the real results of the application of lubricant of rail-wheel systems that utilize the lubrication fleet management system.
