The invention relates to a method for adapting the brake cylinder pressure (pc,actual; pc1/ pc2/ pc3/ pc4) of a pneumatic brake of a rail vehicle (FZG). According to the invention, during a braking process, the momentary actual slip (sactual) between at least one wheel (2) of the rail vehicle (FZG) and a rail (3) is determined, a desired slip (sdesired) between the at least one wheel (2) and the rail (3) is predetermined, and the brake cylinder pressure (pc,actual; pc1, pc2/ pc3, pc4), which corresponds to the difference of the actual slip (sactual) from the predetermined actual slip (sdesired), is modified such that the difference between the desired and actual slip is approximately zero or is at a minimum. The desired slip can be, selectively, in the micro or macro slip range. A braking state factor is determined in the event of a stable braking process, from axle speed measurements and brake cylinder pressures.
Procédé permettant d'adapter la pression (p<SUB>c</SUB>,<SUB>ist</SUB>; p<SUB>c1</SUB>, p<SUB>c2</SUB>, p<SUB>c3</SUB>, p<SUB>c4</SUB>) de cylindre d'un frein pneumatique d'un véhicule ferroviaire (FZG), selon lequel, pendant un processus de freinage, le patinage réel (s<SUB>ist</SUB>) momentané entre au moins une roue (2) du véhicule ferroviaire (FZG) et un rail (3) est déterminé, un patinage idéal (s<SUB>soll</SUB>) entre la roue (2) et le rail (3) est en outre prédéfini, et en fonction de l'écart entre le patinage réel (s<SUB>ist</SUB>) et le patinage idéal prédéfini (s<SUB>soll</SUB>), la pression (p<SUB>c,ist</SUB>; p<SUB>c1</SUB>, p<SUB>c2</SUB>, p<SUB>c3</SUB>, p<SUB>c4</SUB>) de cylindre de frein est modifiée de manière telle que l'écart entre le patinage réel et idéal se rapproche de zéro ou est réduit à un minimum. Le patinage idéal peut se trouver sélectivement dans la plage de micropatinage ou de macropatinage. En cas de processus de freinage stable, un facteur d'état de freinage est déterminé à partir de mesures des vitesses d'essieu et des pressions de cylindre de freinage.
