(EN) IMPROVED METHOD AND SYSTEM OF HYDRAULIC BRAKING FOR VEHICLE WITH COUPLING
(FR) PROCEDE ET SYSTEME DE FREINAGE HYDRAULIQUE AMELIORE POUR VEHICULE AVEC ATTELAGE
Abstract
(EN)
Method for controlling a braking circuit for a vehicle (V) equipped with a coupling (A), the vehicle (V) comprising a hydraulic supply circuit (100) and a hydraulic control circuit (200) equipped with a control device (225), the coupling (A) comprising a hydraulic braking circuit (300) connected to the hydraulic supply circuit (100) and to the hydraulic control circuit (200) and comprising a hydraulic accumulator (360) wherein, when - the vehicle (V) is at rest, and - the pressure within the hydraulic accumulator (360) is less than or equal to a threshold pressure value, the control device (225) produces an increase in pressure of the hydraulic accumulator (360) via the hydraulic control circuit (200).

Procédé de pilotage d'un circuit de freinage pour un véhicule (V) muni d'un attelage (A), le véhicule (V) comprenant un circuit hydraulique d'alimentation (100) et un circuit hydraulique de commande (200) muni d'un dispositif de pilotage (225), l'attelage (A) comprenant un circuit hydraulique de freinage (300) relié au circuit hydraulique d'alimentation (100) et au circuit hydraulique de commande (200) et comprenant un accumulateur (360) hydraulique dans lequel, lorsque - le véhicule (V) est à l'arrêt, et - la pression au sein de l'accumulateur hydraulique (360) est inférieure ou égale à une valeur seuil de pression, le dispositif de pilotage (225) réalise une montée en pression de l'accumulateur (360) hydraulique via le circuit hydraulique de commande (200).
