Title (EN) THROTTLE VALVE CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
(FR) DISPOSITIF DE COMMANDE DE VANNE D'ÉTRANGLEMENT POUR MOTEUR À COMBUSTION INTERNE
(JA) 内燃機関のスロットルバルブ制御装置
Abstract:
(EN) The purpose of the present invention is to provide a novel throttle valve control device for an internal combustion engine, with which the target torque of the internal combustion engine can be accurately generated. To achieve this purpose, the the present invention comprises a target intake new air quantity calculator 41 that calculates target intake new air that will pass through a throttle valve, an EGR gas flow rate calculator 43 that calculates an estimated flow rate of EGR gas that will pass through the throttle valve, a target intake gas rate calculator 44 that calculates a target intake flow rate for gas that will pass through the throttle valve on the basis of the target intake new air flow rate and the estimated EGR flow rate, and a target throttle valve opening degree calculator 45 that calculates a target opening degree for the throttle valve from the target intake gas flow rate. A target torque can be accurately generated because the target throttle opening degree is set on the basis of the target intake new air flow rate and the throttle-passing flow rate for EGR gas passing through the throttle valve.
(FR) Le but de la présente invention est de fournir un nouveau dispositif de commande de vanne d'étranglement pour un moteur à combustion interne, avec lequel le couple cible du moteur à combustion interne peut être généré avec précision. À cet effet, la présente invention comprend un calculateur de quantité 41 d'air d'admission cible neuf qui calcule un air d'admission cible neuf qui va passer à travers une vanne d'étranglement, un calculateur de débit de gaz RGE 43 qui calcule un débit estimé de gaz RGE qui va passer à travers la vanne d'étranglement, un calculateur de débit de gaz d'admission cible 44 qui calcule un débit d'admission cible pour le gaz qui va passer à travers la vanne d'étranglement sur la base du débit d'air d'admission cible neuf et du débit RGE estimé, et un calculateur de degré d'ouverture de vanne d'étranglement cible 45 qui calcule un degré d'ouverture cible pour la vanne d'étranglement à partir du débit de gaz d'admission cible. Un couple cible peut être généré avec précision du fait que le degré d'ouverture de vanne d'étranglement cible est réglé sur la base du débit d'air d'admission cible neuf et du débit de passage d'étranglement pour le gaz RGE passant à travers la vanne d'étranglement.
(JA) 内燃機関の目標トルクを精度良く発生することができる新規な内燃機関のスロットルバルブ制御装置を提供することにある。このため本発明は、スロットルバルブを通過する目標吸入新気を算出する目標吸入新気流量算出部41と、スロットルバルブを通過する推定EGRガス流量を算出するEGRガス流量算出部43と、目標吸入新気流量と推定EGR流量に基づいてスロットルバルブを通過する目標吸入ガス流量を算出する目標吸入ガス量算出部44と、目標吸入ガス流量から目標スロットルバルブ開度を算出する目標スロットルバルブ開度算出部45を備える。目標吸入新気流量とスロットルバルブを通過するスロットル通過EGRガス流量に基づいて目標スロットル開度を設定するので、精度良く目標トルクを発生することができる。
