Abstract

L’invention se rapporte à un dispositif d’optimisation, pour favoriser un freinage régénératif au sein d’un système de freinage comprenant un dispositif de freinage électrique régénératif et un frein mécanique à serrage par actionnement hydraulique, commandé par un système de commande hydraulique qui fournit une pression hydraulique audit frein mécanique par l'intermédiaire d'un circuit d'alimentation hydraulique. Le frein mécanique comprend un actionneur hydraulique de déplacement d’un piston qui applique le serrage, mobile entre une position active et une position de repos. Le système de freinage comporte un circuit d’alimentation (1) hydraulique. Le dispositif d’optimisation comporte un dispositif de précharge (2) agencé pour que l'actionneur du frein ne s'active qu'au-delà d'une pression déterminée non nulle reçue en entrée du circuit d'alimentation, choisie pour être supérieure à une pression de fuite qui existe à l'entrée dudit circuit d'alimentation (1) de frein lorsque le freinage régénératif est activé.
