CA 2400351

A method to facilitate reducing delays in braking applications in a train using a system. The system includes at least one computer for executing brake control functions of the train and a brake pipe that extends along a length of the train for supplying air for brake operations. The train includes a lead locomotive, at least one remote locomotive, and at least one railcar. The method includes sensing a change in airflow in the brake pipe, determining whether the change in air flow is desired, sensing brake pipe pressure, and filtering undesired fluctuations in brake pipe pressure during brake applications based on the determination of whether a change in airflow is desired.

L'invention concerne un procédé qui facilite la réduction des retards intervenant dans les applications de freinage à bord d'un train. Le système décrit comporte au moins un ordinateur exécutant les fonctions de commande de freinage et une conduite du frein qui s'étend sur une longueur du train pour fournir l'air nécessaire aux opérations de freinage. Le train comprend une locomotive de tête, au moins une locomotive distante, et au moins un wagon. Le procédé considéré consiste à déceler un changement de flux d'air dans la conduite du frein, à déterminer si ce changement est souhaité, à déceler la pression dans la conduite du frein, et à filtrer les fluctuations parasites de pression dans la conduite du frein durant les applications de freinage, en fonction du caractère souhaitable ou parasite du chaque changement de flux d'air.
