Title (EN) ELECTRIC POWER STEERING APPARATUS
(FR) APPAREIL DE DIRECTION ASSISTÉE ÉLECTRIQUE
(JA) 電動パワーステアリング装置
Abstract:
(EN) This electric power steering apparatus is provided with two sets of independent armature winding wires and independent control units, wherein: a single power supply connector is divided, at a point near a power supply terminal, into at least four lines; a power supply relay, a filter, and an inverter are connected in order to a line through which a large current flows; and a control circuit unit is connected to a line through which a small current flows and a detection circuit that detects an abnormality of the control circuit unit is provided to the line.
(FR) Appareil de direction assistée électrique pourvu de deux ensembles de fils d'enroulement d'induit indépendants et d'unités de commande indépendantes : un seul connecteur d'alimentation électrique est divisé, au niveau d'un point proche d'une borne d'alimentation électrique, en au moins quatre lignes ; un relais d'alimentation électrique, un filtre et un onduleur sont connectés dans l'ordre à une ligne dans laquelle circule un grand courant ; et une unité de circuit de commande est connectée à une ligne das laquelle circule un petit courant et un circuit de détection qui détecte une anomalie de l'unité de circuit de commande est disposé sur la ligne.
(JA) 2組の独立した電機子巻線と制御ユニットを備え、単一の電源用コネクタを電源ターミナルの近傍で少なくとも4つのラインに分岐し、大電流が流れるラインには電源リレー、フィルタ、インバータ回路を順に接続し、小電流が流れるラインには制御回路部を接続すると共にその異常を検出する検出回路を備える。
