Title (EN) CONTROL DEVICE FOR SOLENOID VALVE DRIVING CIRCUIT AND FAULT DIAGNOSIS METHOD
(FR) DISPOSITIF DE COMMANDE POUR CIRCUIT D'ATTAQUE D'ÉLECTROVANNE ET PROCÉDÉ DE DIAGNOSTIC DE DÉFAUTS
(JA) 電磁弁駆動回路の制御装置および異常診断方法
Abstract: front page image
(EN)When an ignition switch is turned off, a Main OFF command that turns off a cut-off main transistor (58a) is output to the cut-off main transistor (58a) and a switching command that switches drive transistors (56a-56d) is output to the drive transistors (56a-56d). In that state, solenoid currents (Ia-Id) detected by current sensors (59a-59d) are compared to a threshold (Idref) to determine (diagnose) whether the cut-off main transistor (58a) is operating properly (a DC power source (57) and the drive transistors (56a-56d) are cut off).
(FR)Lorsqu'un commutateur d'allumage est coupé, une instruction de coupure principale qui bloque un transistor principal de coupure (58a) est délivrée au transistor principal de coupure (58a) et une instruction de commutation qui commute des transistors d'attaque (56a à 56d) est délivrée aux transistors d'attaque (56a à 56d). Dans cet état, des courants de solénoïde (Ia à Id) détectés par des capteurs de courant (59a à 59d) sont comparés à un seuil (Idref) pour déterminer (diagnostiquer) si le transistor principal de coupure (58a) fonctionne correctement (une source de courant continu (57) et les transistors d'attaque (56a à 56d) sont coupés).
(JA)イグニッションスイッチがオフとされたときには、遮断用メイントランジスタ58aをオフとさせるメインオフ指令を遮断用メイントランジスタ58aに出力すると共に駆動用トランジスタ56a~56dをスイッチングさせるスイッチング指令を駆動用トランジスタ56a~56dに出力する。そして、その状態で電流センサ59a~59dにより検出されたソレノイド電流Ia~Idを閾値Idrefと比較して遮断用メイントランジスタ58aが正常に作動している(直流電源57と駆動用トランジスタ56a~56dとが遮断されている)か否かを判定(診断)する。
