Abstract

　常に正確にセンサの異常を検出できる、排気濾過装置におけるセンサの異常検出装置、およびその検出方法を提供することを目的とする。 　上記目的を達成するため、フィルタ上流側圧力センサと、該フィルタ上流側圧力センサによって検出された前記フィルタの上流側圧力値から、前記フィルタの上下流間での圧力差の実測値を減算し、前記フィルタの下流側における圧力値を算出するフィルタ下流側圧力算出手段と、内燃機関の運転状態に基づいて前記フィルタの下流側における圧力値を推定するフィルタ下流側圧力推定手段と、前記圧力算出値と圧力推定値との差を閾値と比較し、差圧センサとフィルタ上流側圧力センサの少なくとも一方の機能が正常に作動していないことを検出する異常検出手段とを備えてセンサの異常検出装置を構成した。
