Title
(EN) COOLING FAN MOTOR/INVERTER SYSTEM FOR VEHICLES AND CONTROL METHOD AND PROGRAM THEREFOR

Abstract
(EN) A cooling fan motor/inverter system for vehicles, comprising: a motor control device (21) having a switching element (22), converting DC power supplied from a high-voltage power supply (4) into three-phase AC power, and supplying power to a three-phase motor (3); a first control unit (24) that controls the motor control device (21); an isolation-type CAN driver (82) that operates using power supplied from a low-voltage power supply (5) and transfers information to and from a vehicle-side ECU (6) on the host vehicle side of the cleaning fan motor/inverter system (2) for vehicles; and an isolation unit (8) that electrically isolates a low-voltage grid having power supplied thereto from the low-voltage power supply (5) and a high-voltage grid having power supplied thereto from the high-voltage power supply (4). If an error has been detected in the switching element (22), the first control unit (24) outputs error information to the vehicle-side ECU (6), via the isolation-type CAN driver (82), notifying that there is an error in the three-phase motor (3) control.
(FR) L'invention porte sur un système de moteur/onduleur de ventilateur de refroidissement pour véhicules, lequel système comprend : un dispositif de commande de moteur (21) ayant un élément de commutation (22), convertissant une énergie en courant continu fournie à partir d'une alimentation haute tension (4) en une énergie en courant alternatif triphasé, et fournissant de l'énergie à un moteur triphasé (3) ; une première unité de commande (24) qui commande le dispositif de commande de moteur (21) ; un dispositif d'attaque de bus CAN du type à isolation (82) qui fonctionne à l'aide d'une énergie fournie à partir d'une alimentation basse tension (5) et qui transfère une information vers et à partir d'une unité de commande électronique côté véhicule (6) sur le côté véhicule hôte du système de moteur/onduleur de ventilateur de nettoyage (2) pour véhicules ; et une unité d'isolation (8) qui isole électriquement un réseau basse tension ayant une énergie fournie à celui-ci à partir de l'alimentation basse tension (5) et un réseau haute tension ayant une énergie fournie à celui-ci à partir de l'alimentation haute tension (4). Si une erreur a été détectée dans l'élément de commutation (22), la première unité de commande (24) fournit en sortie une information d'erreur à l'unité de commande électronique côté véhicule (6), par l'intermédiaire du dispositif d'attaque de bus CAN du type à isolation (82), indiquant qu'il y a une erreur dans la commande de moteur triphasé (3).
(JA) スイッチング素子(22)を有し、高電圧電源(4)から供給される直流電力を三相交流電力に変換し、三相モータ(3)に電力供給するモータ制御装置(21)と、モータ制御装置(21)を制御する第1制御部(24)と、低電圧電源(5)から供給される電力によって作動し、車両用クーリングファンモータ・インバータシステム2の上位の車両側の車両側ECU(6)と情報を授受する絶縁型CANドライバ(82)と、低電圧電源(5)から電力が供給される低電圧系統と、高電圧電源(4)から電力が供給される高電圧系統とを電気的に絶縁させる絶縁部(8)とを具備し、第1制御部(24)は、スイッチング素子(22)に異常が検出された場合に、絶縁型CANドライバ(82)を介して、車両側ECU(6)に対して、三相モータ(3)の制御に異常がある旨を通知する異常情報を出力する。
