Abstract

 油圧駆動車両の原動機回転数制御装置は、原動機により駆動される油圧ポンプと、油圧ポンプからの圧油により駆動する走行用油圧モータと、操作量に応じた走行指令を出力する操作部材と、操作部材の操作量に応じて出力される走行指令に基づいて、油圧ポンプから油圧モータへの圧油の流れ、または油圧ポンプから吐出される圧油の流量を制御する流れ制御装置と、指令に基づいて原動機の目標回転数を出力する目標回転数出力装置と、原動機回転数を目標回転数となるように制御する回転数制御装置と、車速を検出する車速検出装置と、操作部材の操作量に応じた目標車速を演算する車速演算装置とを備える。回転数制御装置は、車速検出装置により検出された車速と車速演算装置により演算された目標車速とに基づいて、目標回転数を補正する補正装置を有する。
