Title (EN) TORQUE MONITORING DEVICE AND INTERNAL COMBUSTION ENGINE CONTROL SYSTEM
(FR) DISPOSITIF DE SURVEILLANCE DE COUPLE ET SYSTÈME DE COMMANDE DE MOTEUR À COMBUSTION INTERNE
(JA) トルク監視装置および内燃機関制御システム
Abstract:
(EN) This torque monitoring device monitors whether or not an estimated torque, which is an estimated value of the actual torque of an internal combustion engine, is in an abnormal state of having diverged from an engine required torque that is required in the internal combustion engine. The torque monitoring device comprises: discrete value setting units (34a, 34b, 34c, B16) that set discrete values to greater values as a divergence amount between the estimated torque and the engine required torque increases; an integration unit (34d) that calculates an integrated value, which is a value integrating the discrete values; and an abnormality determination unit (34e) that determines the torque to be in an abnormal state when the integrated value is equal to or greater than a prescribed abnormality determination threshold value.
(FR) L'invention concerne un dispositif de surveillance de couple qui surveille si un couple estimé, lequel est une valeur estimée du couple réel d'un moteur à combustion interne, se trouve ou non dans un état anormal consistant à avoir divergé par rapport à un couple moteur exigé qui est exigé dans le moteur à combustion interne. Le dispositif de surveillance de couple comprend : des unités de réglage de valeur discrète (34a, 34b, 34c, B16) qui définissent des valeurs discrètes à des valeurs supérieures à mesure qu'une amplitude de divergence entre le couple estimé et le couple moteur exigé augmente ; une unité d'intégration (34d) qui calcule une valeur intégrée, laquelle est une valeur intégrant les valeurs discrètes ; et une unité de détermination d'anomalie (34e) qui détermine que le couple se trouve dans un état anormal lorsque la valeur intégrée est égale ou supérieure à une valeur seuil de détermination d'anomalie prescrite.
(JA) トルク監視装置は、内燃機関の実トルクの推定値である推定トルクが、内燃機関に要求されている機関要求トルクと乖離したトルク異常状態であるか否かを監視するトルク監視装置であって、推定トルクと機関要求トルクとの乖離量が大きいほど、計数値を大きい値に設定する計数値設定部(34a、34b、34c、B16)と、計数値を積算した値である積算値を算出する積算部(34d)と、積算値が所定の異常判定閾値以上になった場合に、トルク異常状態であると判定する異常判定部(34e)と、を備える。
