Title
(EN) CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
(FR) DISPOSITIF DE COMMANDE POUR MOTEUR À COMBUSTION INTERNE
(JA) 内燃機関の制御装置
Abstract
(EN)  This control device for an engine (1) controls at least the throttle opening and includes: a target opening calculation unit (throttle opening adjustment unit (541)) that selects one of a first requirement value for the throttle opening which corresponds to the torque requirement and a second requirement value which corresponds to another requirement, and calculates the target throttle opening on the basis of the selected requirement value. If the first requirement value is selected, an abnormality determination unit (560) determines an abnormality depending on the magnitude of difference between the first requirement value and the target throttle opening. If the second requirement value is selected, an abnormality is determined depending on whether the target throttle opening is equal to or greater than a predetermined upper-limit value.
(FR)  La présente invention concerne un dispositif de commande pour moteur (1) qui commande au moins l'ouverture du papillon des gaz et comprend : une unité de calcul d'ouverture cible (unité d'ajustement d'ouverture de papillon des gaz (541)) qui sélectionne l'une parmi une première valeur exigée pour l'ouverture du papillon des gaz qui correspond au couple demandé et une seconde valeur exigée qui correspond à une autre exigence, et calcule l'ouverture cible du papillon des gaz sur la base de la valeur exigée sélectionnée. Si la première valeur exigée est sélectionnée, une unité de détermination d'anomalie (560) détermine une anomalie en fonction de l'amplitude de la différence entre la première valeur exigée et l'ouverture cible du papillon des gaz. Si la seconde valeur exigée est sélectionnée, une anomalie est déterminée si l'ouverture cible du papillon des gaz est supérieure ou égale à une valeur limite supérieure prédéterminée.
(JA)  少なくともスロットル開度を制御するエンジン(1)の制御装置において、トルク要求に対応するスロットル開度の第1の要求値と、他の要求に対応する第2の要求値とのいずれかを選択し、この選択した要求値から目標スロットル開度を算出する目標開度算出部(スロットル開度の調停部(541))を備える。第1の要求値が選択される場合、異常判定部(560)により、第1の要求値と目標スロットル開度との偏差の大きさによって異常を判定する。第2の要求値が選択される場合、目標スロットル開度が所定の上限値以上であるか否かによって、異常を判定する。
