Abstract
(EN)
An electric motor control device (10) comprises: a target torque instruction unit (15) that gives instructions regarding a target torque to each of a right side control circuit (21R) and a left side control circuit (21L); and a failure occurrence identifier (18) that identifies if there is an occurrence of failure of the right side control circuit and the left side control circuit. If it is identified that there is an occurrence of failure of one of the two control circuits, the target torque instruction unit: gives instructions regarding a fail-safe torque lower than a normal target torque, as the target torque, to a failure-identified control circuit; and gives instructions regarding a failure time target torque lower than the normal target torque and higher than the fail-safe torque, to a normal control circuit.
(FR)
L'invention concerne un dispositif de commande de moteur électrique (10) comprenant : une unité d'instruction de couple cible (15) qui donne des instructions concernant un couple cible à chacun d'un circuit de commande côté droit (21R) et d'un circuit de commande côté gauche (21L) ; et un identifiant d'occurrence de défaillance (18) qui identifie s'il y a une occurrence de défaillance du circuit de commande côté droit et du circuit de commande côté gauche. S'il est identifié qu'il y a une occurrence de défaillance de l'un des deux circuits de commande, l'unité d'instruction de couple cible : donne des instructions concernant un couple à sécurité intégrée inférieur à un couple cible normal, en tant que couple cible, à un circuit de commande identifié comme défaillant ; et donne des instructions concernant un couple cible de temps de défaillance inférieur au couple cible normal et supérieur au couple à sécurité intégrée à un circuit de commande normal.

電動機制御装置(10)は、右側制御回路(21R)と左側制御回路(21L)とにそれぞれ目標トルクを指示する目標トルク指示部(15)と、右側制御回路および左側制御回路の故障発生の有無を特定する故障発生特定部(18)と、を備える。目標トルク指示部は、2つの制御回路のうちの一方の故障発生が有ると特定された場合に、故障特定制御回路に対しては、目標トルクとして正常目標トルクよりも低いフェイルセーフ用トルクを指示し、正常制御回路に対しては、正常目標トルクよりも低く、且つ、フェイルセーフ用トルクよりも高い故障時目標トルクを指示する。
