Abstract:
(EN) A brake device for a rail vehicle has at least one brake cylinder (16) and a pressure-regulating apparatus (12) for making available a regulating pressure (Pa) for the brake cylinder (16) on the basis of a supply pressure (Ps) which is made available. In order to achieve improved regulation of the braking effect, it is proposed to sense the regulating pressure (Pa) downstream of the pressure-regulating apparatus (12), to estimate a brake cylinder pressure (Pb) in the brake cylinder (16) on the basis of this sensed regulating pressure (Pa), and to actuate the pressure-regulating apparatus (12) as a function of the estimated brake cylinder pressure (Pb).
(FR) L’invention concerne un dispositif de freinage pour un véhicule ferroviaire, ledit dispositif présentant au moins un cylindre de frein (16) et un dispositif de régulation de pression (12) destiné à fournir une pression de régulation (Pa) pour le cylindre de frein (16) à partir d’une pression d’alimentation (Ps) fournie. L’invention vise à parvenir à une meilleure régulation de l’effet de freinage. A cet effet, la pression de régulation (Pa) est détectée en aval du dispositif de régulation de pression (12), sur la base de cette pression de régulation (Pa) détectée, une pression de cylindre de freinage (12) régnant dans le cylindre de freinage (16) est estimée et le dispositif de régulation de pression (12) est piloté en fonction de la pression de cylindre de frein (Pb) estimée.
(DE) Eine Bremsvorrichtung für ein Schienenfahrzeug weist mindestens einen Bremszylinder (16) und eine Druckregeleinrichtung (12) zum Bereitstellen eines Regeldrucks (Pa) für den Bremszylinder (16) ausgehend von einem bereitgestellten Versorgungsdruck (Ps) auf. Um eine verbesserte Regelung der Bremswirkung zu erzielen, wird vorgeschlagen, den Regeldruck (Pa) stromab der Druckregeleinrichtung (12) zu erfassen, auf Basis dieses erfassten Regeldrucks (Pa) einen Bremszylinderdruck (Pb) im Bremszylinder (16) abzuschätzen und die Druckregeleinrichtung (12) in Abhängigkeit von dem abgeschätzten Bremszylinderdruck (Pb) anzusteuern.
