Abstract

A rail vehicle (100) obtains a basic parameter (µ) reflecting an initial value of a friction coefficient (µ_e) relating to a rail segment (310) in a rail-way network (300) and validates the basic parameter (µ) through a procedure involving: measuring individual rotational speeds (ω₁, ω₂, ω₃, ω₄) of the axels to which the wheels (151, 152, 153, 154) of the rail vehicle (100) are connected while applying a gradually increasing brake force (BF) to a specific one of said axles; determining, while applying the gradually increasing brake force (BF), an absolute difference between the rotational speed (ω₂) of the specific one of said axles and an average rotational speed of said axles except the specific one of said axles; and in response to the absolute difference exceeding a threshold value deriving a parameter (µ_m) reflecting a measured value of the friction coefficient (µ_e); checking whether the measured value of the friction coefficient (µ_e) lies within an acceptance interval from the basic parameter (µ); and if so, assigning the validated value of the friction coefficient equal to the measured value of the friction coefficient (µ_e). Then, a friction data message (M(µe)) is emitted that contains the validated value of the friction coefficient.
