Abstract

Die Erfindung bezieht sich auf ein Verfahren zur Reibungsbeeinflussung zwischen Rad und Schiene, bei welchem eine Ausbringung (1) eines Reibungsbeeinflussungsmittels (2) auf zumindest ein erstes Rad (36) eines Schienenfahrzeugs und/oder zumindest eine Schiene eines Gleises (43) mittels zumindest eines ersten Reibungsbeeinflussungsmittelspenders (3) des Schienenfahrzeugs in Abhängigkeit von mittels zumindest einer Ortungseinrichtung (6) des Schienenfahrzeugs erfassten Ortsinformationen des Schienenfahrzeugs ausgelöst wird.Für einen effizienten und umweltfreundlichen Einsatz des Reibungsbeeinflussungsmittels (2) wird vorgeschlagen, dass die Ausbringung (1) des Reibungsbeeinflussungsmittels (2) auf Grundlage von Vergleichen (11) der Ortsinformationen mit Infrastrukturinformationen in Abhängigkeit einer Gleisgeometrie, wobei insbesondere eine Gleisbogenlänge (b) berücksichtigt wird, in Abhängigkeit einer Trassierung, wobei insbesondere eine Gleisneigung berücksichtigt wird, und/oder in Abhängigkeit einer Annäherung des Schienenfahrzeugs an eine vor dem Reibungsbeeinflussungsmittel (2) zu schützende Infrastruktur ausgelöst wird, wobei die auszubringende Reibungsbeeinflussungsmittelmenge (V) in Abhängigkeit eines Reibungsbeeinflussungsmittelverbrauchs eingestellt wird.The invention relates to a method for influencing friction between wheel and rail, in which application (1) of a friction influencing agent (2) to at least a first wheel (36) of a rail vehicle and/or at least one rail of a track (43) by means of at least one first dispenser (3) of the friction-modifying agent (3) of the rail vehicle is triggered depending on location information of the rail vehicle detected by means of at least one locating device (6) of the rail vehicle.For an efficient and environmentally friendly use of the friction-modifying agent (2), it is proposed that the deployment (1) of the friction-modifying agent (2 ) on the basis of comparisons (11) of the location information with infrastructure information depending on a track geometry, taking into account a track curve length (b) in particular, depending on a routing, taking into account a track inclination in particular, and/or depending on pendency of the rail vehicle approaching an infrastructure to be protected from the friction modifier (2), the amount (V) of the friction modifier to be deployed being set as a function of the consumption of the friction modifier.
