Abstract
(EN)
An electronic brake system according to an embodiment has a hydraulic circuit for supplying a liquid pressure to a wheel cylinder. The electronic brake system comprises: multiple electronic valves provided to open/close a channel of the hydraulic circuit; and a controller for correcting a target current of a currently operating electronic valve among the multiple electronic valves on the basis of a voltage that is input from a vehicle battery during braking control, or on the basis of a feedback current from the multiple electronic valves, and increasing the current supplied to the currently operating electronic valve such that the current thereof reaches the corrected target current.

Un mode de réalisation de l'invention concerne un système de frein électronique, qui a un circuit hydraulique pour délivrer une pression de liquide à un cylindre de roue. Le système de frein électronique comprend : de multiples vannes électroniques prévues pour ouvrir/fermer un canal du circuit hydraulique ; et un dispositif de commande pour corriger un courant cible d'une vanne électronique actuellement en fonctionnement parmi les multiples vannes électroniques sur la base d'une tension qui est entrée à partir d'une batterie de véhicule pendant une commande de freinage, ou sur la base d'un courant de rétroaction provenant des multiples vannes électroniques, et accroître le courant délivré à la vanne électronique actuellement en fonctionnement de telle sorte que le courant de celle-ci atteint le courant cible corrigé.
