PROBLEM TO BE SOLVED: To quickly and accurately position a work machine at a target position while effectively preventing hunting action.SOLUTION: A control device stores an inclination of a vehicle machine that is inputted from the machine inclination sensor as a time series data, and a specified time amount of the time series data is subjected to Fourier transformation, thus a vehicle machine inclination fluctuation frequency is calculated. By using a work machine correction coefficient that is defined by a correction data about the work machine correction coefficient and the machine inclination fluctuation frequency being stored in advance and the vehicle machine inclination fluctuation frequency, a latest actual position of the work machine being inputted from a position detection member is corrected to calculate a corrected actual position. An inclination actuator is operated so that a deviation between the corrected actual position and the target position falls within a specified threshold value.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2017,JPO&INPIT【課題】ハンチング動作を有効に防止しつつ、作業機を目標位置に迅速且つ正確に位置させる。【解決手段】制御装置は、本機傾斜センサから入力される車輌本機の傾きを時系列データとして記憶し、前記時系列データの所定時間分をフーリエ変換して車輌本機傾き変動周波数を算出し、予め記憶されている本機傾き変動周波数及び作業機用補正係数に関する補正データと前記車輌本機傾き変動周波数とによって画される作業機用補正係数を用いて位置検出部材から入力された作業機の最新の実位置を補正して補正実位置を算出し、前記補正実位置と前記目標位置との偏差が所定閾値内に収まるように傾斜アクチュエータを作動させる。【選択図】図6
