Claims (1)
- 内燃機関の吸気系の吸気通路から取り出そうとする負圧よりも大きな負圧を発生させるエゼクタと、該エゼクタを機能、或いは機能停止させる状態変更手段とを有して構成されるとともに、前記内燃機関のアイドル時の吸気流量を調節するアイドル流量調節手段と独立した経路に配設される負圧発生装置を制御する負圧発生装置の制御装置であって、
吸気流量の増大に関する前記エゼクタの応答性は前記アイドル流量調整手段よりも低く、アイドル時に吸気流量を前記内燃機関が必要とする吸気流量に調節するにあたって、前記アイドル流量調節手段を制御するための制御量のうち、応答性を必要としない所定の制御量で指標される吸気流量が前記エゼクタを機能させたときに増大する吸気流量よりも大きいかどうかを判断することにより、前記状態変更手段を機能させてもアイドル回転数の維持又は制御性を確保できるかどうかを判断し、前記内燃機関の制御量のうち応答性を必要としない制御量で指標される吸気流量が前記エゼクタを機能させたときに増大する吸気流量よりも大きく確保できると判断した場合には、前記アイドル流量調節手段による調整が実行される前に前記状態変更手段を機能させる優先制御手段を備えることを特徴とする負圧発生装置の制御装置。
