Abstract

　指令手段による指令値に応じて第１目標回転数Ｎhと高速制御の領域Ｆ1とを設定する。第１目標回転数Ｎhに基づいて低回転側の第２目標回転数Ｎ2と高速制御の領域Ｆ2とを設定する。高速制御の領域Ｆ2でのエンジン制御中に、第１の所定ポンプ容量である第１設定位置Aをエンジン負荷とエンジン出力トルクとのマッチング点が超えたとき、高速制御の領域Ｆ2を高速制御の領域Ｆ1側にシフトする。ポンプ吐出圧とアクチュエータの負荷圧との差圧が、ポンプ制御装置8でのロードセンシング差圧を満たすことになった高速制御の領域Ｆ3を新たな高速制御の領域として、高速制御の領域Ｆ3でのエンジンの制御を行い、ロードセンシング差圧を満たさないときには、高速制御の領域Ｆ1までシフトする。これにより、エンジンの燃費を向上させ、しかも、作業機の最大速度が必要とされる場合には、必要とされる作業機の最大速度を低下させずに与えられるエンジンの制御装置及びその制御方法が提供できる。
