Title (EN) METHOD AND SYSTEM FOR IMPROVING SAFETY FOR A VEHICLE BRAKING ARRANGEMENT
(FR) PROCÉDÉ ET SYSTÈME PERMETTANT D’AMÉLIORER LA SÉCURITÉ POUR UN SYSTÈME DE FREINAGE DE VÉHICULE
Abstract:
(EN) The present invention relates to a method for improving safety for a vehicle braking arrangement having air circuits for supplying compressed air for service brakes and parking brake. The method comprises the step of determining (S1) the compressed air pressure in the respective air circuits. The method further comprises the steps of: determining (S2) the order in which said air circuits are pressurised for the respective circuits during air pressure build up; and taking action (S3) if the parking brake air circuit is pressurised prior to any of the service brake air circuits. The present invention also relates to a system for improving safety for a vehicle braking arrangement having air circuits for supplying compressed air for service brakes and parking brake. The present invention also relates to a vehicle. The present invention also relates to a computer program and a computer program product.
(FR) La présente invention concerne un procédé permettant d'améliorer la sécurité pour un système de freinage de véhicule ayant des circuits d'air qui servent à fournir de l'air comprimé aux freins de service et au frein à main. Le procédé comprend l'étape consistant à déterminer (S1) la pression d'air comprimé dans les circuits d'air respectifs. Le procédé comprend en outre les étapes consistant : à déterminer (S2) l'ordre dans lequel lesdits circuits d'air sont mis sous pression pour les circuits respectifs pendant l'accumulation de pression d'air ; et à exécuter une action (S3) si le circuit d'air de frein à main est mis sous pression avant les circuits d'air de freins de service. L'invention concerne également un système permettant d'améliorer la sécurité pour un système de freinage de véhicule ayant des circuits d'air qui servent à fournir de l'air comprimé aux freins de service et au frein à main. L'invention porte également sur un véhicule. Elle se rapporte aussi à un programme d'ordinateur et à un produit programme d'ordinateur.
