Abstract
【解決手段】 エンジン負荷QCが所定値以上であり、加速状態判定手段M1がタービン25bの加速状態を判定し、かつ過給圧制御状態判定手段M2がターボチャージャの過給圧制御手段(バイパスバルブ、ウエストゲートおよびバリアブルフラップ)が最大過給圧制御状態(閉弁状態)にあると判定したときに、つまり実過給圧πCおよび収束値算出手段M4で算出した過給圧の収束値πC* から遅れ係数算出手段M5が算出したターボチャージャの遅れ係数αが該ターボチャージャについて固有の値を示すときに、その遅れ係数αに基づいて過給圧制御手段の故障を判定するので、エンジン負荷QCが急激に変化して過給圧πCの応答に遅れが生じているときでも高い故障検知精度を確保するとともに故障検知を行う頻度を高めることができる。

Description
また請求項3に記載された発明によれば、請求項1の構成に加えて、前記故障検知許可手段は、エンジンの点火時期のリタード量が所定値以上のときに過給圧制御手段の故障検知を禁止することを特徴とするエンジンの過給装置における過給圧制御手段の故障検知装置が提案される。
(a)スロットル開度がアイドル判定値以下(スロットル開度が全閉状態)
(b)過給圧比が所定値以上(過大な過給状態)
(c)スロットル開度の変化率が閉弁方向に所定値以上(スロットルバルブの急閉状態)の何れかである。
πC(t)=α×πC* (t−Δt)+(1−α)×πC(t−Δt)
で与えられる。この式を遅れ係数α(瞬時値)について解くと、
α={πC(t)−πC(t−Δt)}/{πC* (t−Δt)−πC(t−Δt)}が得られる。ここで、Δtは今回値および前回値の算出の時間差である。Δtが小さいと圧力比πCの変化量が小さいために外乱の影響を受けやすくなり、Δtが200msec以上で分布が安定するため、実施の形態ではΔt=200msecに設定している(図8および図9参照)。
α={πC(t)−πC(t−Δt)}/{πC* (t−Δt)−πC(t−Δt)}により算出する。続くステップS42で前記故障検知許可フラグが「1」にセットされていて故障検知が許可されていれば、ステップS43で検知回数カウンタをインクリメントし、ステップS44で遅れ係数α(瞬時値)を積算し、ステップS45で遅れ係数α(積算値)を積算回数で除算して遅れ係数α(平均値)を算出する。この遅れ係数αの算出は、遅れ係数算出手段M5(図5参照)により行われる。
