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。
