Abstract

　回転数ピックアップ７１（走行速度検出手段）、油圧センサ７２（走行操作検出手段）、油圧センサ７３（駆動状況検出手段）、電圧センサ７４（Ｔ／Ｍ速度段検出手段）により油圧式走行車両の走行状態に関するパラメータを検出し、コントロールユニット８０、電磁比例弁８１、エンジン制御装置８２、モータレギュレータ３３により、その走行状態に関するパラメータに基づいて油圧式走行車両の運転状態を判定し、その判定結果に応じて油圧走行モータ１４を含む走行系の等価容量と油圧走行モータ１４に供給される最大流量とを制御する。このように走行状態に応じてポンプ流量とモータ容量を制御することにより、燃費を悪化させることなく良好な走行性能を確保することができる。
