Abstract: A controller (140) controls a set of electrically operated brake units (141a, 151a; 141b, 151b; 142a, 152a; 142b, 152b; 143a, 153a; 143b, 153b; 144a, 154a; 144b, 154b) of a rail vehicle (100), which has wheels arranged in pairs of first and second wheels on 5 a respective common wheel axle (131, 132, 133, 134), where each wheel is individually braked via a respective brake unit in the set of electrically operated brake units. The controller (140) repeatedly determines a respective adhesion parameter (µ1a, µ1a, µ2a, µ2b, µ3a, µ3b, µ4a, µ4b) reflecting a friction coefficient between each 10 wheel (101a, 101b, 102a, 102b, 103a, 103b, 104a, 104b) of the rail vehicle (100) and a rail upon which the wheel travels. The controller (140) compares repeatedly compares the respective adhesion parameters (µ1a, µ1b, µ2a, µ2b, µ3a, µ3b, µ4a, µ4b) pairwise to one another. In each pair, first and second adhesion parameters 15 (µ1a,µ1b; µ2a, µ2b; µ3a, µ3b; µ4a, µ4b) are compared to one another, which adhesion parameters have been determined for the first and second wheels on the common wheel axle (131, 132, 133, 134). The controller (140) reports a respective adhesion parameter (µ1, µ2, µ3, µ4) for one of said common wheel axles (131, 132, 133, 20 134) if and only if a ratio (µa/µb) between the first and second adhesion parameters (µ1a, µ1b; µ2a, µ2b; µ3a, µ3b; µ4a, µ4b) is within a first predefined threshold interval (EQ1) around a factor one.
