Abstract
【解決手段】 車両が備える内燃機関50のインテークマニホールド14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30と、エゼクタ30を機能、或いは機能停止させるVSV1とを有して構成される負圧発生装置100を制御するためのECU40Aであって、吸気温に応じて吸気温が所定値β以下のときに、VSV1がエゼクタ30を機能させるように制御されることを禁止する特定禁止制御手段を備える。このVSV1は、水温が所定温度T1よりも大きく、且つ所定温度T2よりも小さいときに、さらにスロットル開度が所定値αよりも小さいときに、エゼクタ30を利用してブレーキブースタ22に負圧を確保すべく、エゼクタ30を機能させるように制御される。

Claims (3)
- 車両が備える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負圧発生装置を制御するための負圧発生装置の制御装置であって、
吸気の温度に応じて、前記状態変更手段が前記エゼクタを機能させるように制御されることを禁止する特定禁止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。 - 前記特定禁止制御手段が、さらに前記吸気通路から取り出そうとする負圧が負の値で所定値以下である場合に、前記状態変更手段が前記エゼクタを機能させるように制御されることを禁止することを特徴とする請求項1記載の負圧発生装置の制御装置。
- 前記特定禁止制御手段が、冷間時に前記状態変更手段が前記エゼクタを機能させるように制御されるときに、前記状態変更手段が前記エゼクタを機能させるように制御されることを禁止することを特徴とする請求項1または2記載の負圧発生装置の制御装置。
