Title
(EN) ADAPTIVE BRAKE SCHEME DURING A LOCOMOTIVE DISTRIBUTED POWER COMMUNICATION LOSS
(FR) SYSTÈME DE FREIN ADAPTATIF DURANT UNE PERTE DE COMMUNICATION DE PUISSANCE DISTRIBUÉE D'UNE LOCOMOTIVE
Abstract
(EN) An adaptive brake system for a distributed power train responsive to an interruption in a communication system for the train and a brake application initiated at the lead locomotive, reduces the brake pipe fluid pressure at a lead locomotive and a remote locomotive to a predetermined pressure level to reduce in-train forces that may occur as a result of the pressure differentials in the brake pipe line of the lead and remote locomotives.
(FR) L'invention porte sur un système de frein adaptatif pour une transmission de puissance distribuée sensible à une interruption dans un système de communication pour la transmission et une application de freinage amorcée au niveau de la locomotive de tête, lequel système de frein adaptatif réduit la pression de fluide de conduite du frein au niveau de la locomotive de tête et d'une locomotive à distance jusqu'à un niveau de pression prédéterminé pour réduire des forces dans la transmission qui peuvent apparaître par suite des différentiels de pression dans la conduite de frein des locomotives de tête et à distance.
