WORK MACHINE, SYSTEM INCLUDING WORK MACHINE AND METHOD FOR CONTROLLING WORK MACHINE
To provide a work machine, a system including a work machine and a method for controlling a work machine that can reduce an error caused by the position of a work machine.SOLUTION: A controller 8 acquires, with a load value W0b in a bucket 3c with a basic position of a work machine 3 as a reference value, load values W0a, W0c in the bucket 3c with a different position from the basic position as comparison values. The controller 8 generates in advance correction data in accordance with a position of the work machine 3 based on the reference value and the comparison value. The controller 8 detects a current position of the work machine 3, and calculates, based on the correction data, a correction amount AAd of a load value in the bucket 3c with the current position of the work machine 3. The controller 8 corrects a load value W in the bucket 3c with the current position of the work machine 3 by using the correction amount AAd, and acquires a load value WP after the correction.SELECTED DRAWING: Figure 2
【課題】作業機の姿勢による誤差を低減できる作業機械、作業機械を含むシステムおよび作業機械の制御方法を提供する。【解決手段】コントローラ８は、作業機３の基本姿勢でのバケット３ｃ内の荷重値Ｗ０ｂを基準値とし、その基本姿勢とは異なる姿勢でのバケット３ｃ内の荷重値Ｗ０ａ、Ｗ０ｃを比較値として取得する。コントローラ８は、基準値と比較値とに基づき、作業機３ｃの姿勢に応じた補正データを予め生成する。コントローラ８は、作業機３の現在の姿勢を検知し、補正データに基づき、作業機３の現在の姿勢におけるバケット３ｃ内の荷重値の補正量ＡＡｄを算出する。コントローラ８は、上記補正量ＡＡｄを用いて作業機３の現在の姿勢におけるバケット３ｃ内の荷重値Ｗを補正して補正後の荷重値ＷＰを取得する。【選択図】図２
