Abstract

　強制再生終了後の浄化判定で浄化不十分と判定された後の強制再生、強制再生が未完了のまま時間切れとなった後の強制再生、車両の走行距離が所定の判定用距離よりも小さい状態でＤＰＦの前後差圧が所定の第１判定用差圧よりも大きくなったときの強制再生のいずれかである緊急再生の場合には、手動再生を促す警報を発し、その後、手動再生の指示を受けたときには手動再生を実施し、手動再生の指示を受けないまま所定の条件下になったときには自動再生を実施する。これにより、排気ガス中のＰＭを浄化するためのＤＰＦの強制再生において、緊急再生の際に、手動再生が選択されなくても、強制再生を確実に実施し、運転者の負担を減少して利便性を向上させる。
