Title
(EN) ELECTRIC POWER STEERING DEVICE
(FR) DISPOSITIF ÉLECTRIQUE DE DIRECTION ASSISTÉE
(JA) 電動パワーステアリング装置
Abstract
(EN) [Problem] To provide an electric power steering device capable of reducing a driver's burden in steering even when a failure occurs. [Solution] The electric power steering device comprises: a plurality of systems equipped with drive circuits (20a, 20b) for driving corresponding motor coils (3a, 3b); and a control unit (10) for controlling the control amounts of the drive circuits (20a, 20b). When a failure occurs in at least one of the systems including the motor coils (3a, 3b), the control unit (10) reduces the control amount of a system in which the failure has occurred to less than the control amount in normal time or stops the driving by the system in which the failure has occurred and increases the control amount of a system in which the failure does not occur to greater than the control amount in normal time.
(FR) La présente invention a pour objectif de fournir un dispositif électrique de direction assistée capable de réduire le fardeau du conducteur pour manœuvrer la direction même lorsqu'une panne se produit. Pour ce faire, l'invention concerne un dispositif électrique de direction assistée comprenant : une pluralité de systèmes équipés de circuits d'entraînement (20a, 20b) pour l'entraînement de bobines de moteur correspondantes (3a, 3b) ; et une unité de commande (10) pour la commande des valeurs de commande des circuits d'entraînement (20a, 20b). Lorsqu'une panne se produit dans au moins un des systèmes, y compris les bobines du moteur (3a, 3b), l'unité de commande (10) réduit la valeur de commande d'un système dans lequel la panne s'est produite à une valeur inférieure à la valeur de commande en temps normal ou arrête l'entraînement par le système dans lequel la panne s'est produite et augmente la valeur de commande d'un système dans lequel la panne ne se produit pas à une valeur supérieure à la valeur de commande en temps normal.
