WORK MACHINE, SYSTEM INCLUDING WORK MACHINE, AND METHOD FOR CONTROLLING WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/069848
Kind Code:
A1
Abstract:
A controller (8) defines a value W0b of the load in a bucket (3c) at a basic posture of a work machine (3) as a reference value, and acquires as comparative values the values W0a, W0c of loads in the bucket (3c) at postures differing from the basic posture. The controller (8) generates in advance correction data corresponding to the posture of the work machine (3c) on the basis of the reference value and the comparative values. The controller (8) detects the current posture of the work machine (3) and calculates a correction amount AAd of the value of the load in the bucket (3c) at the current posture of the work machine (3) on the basis of the correction data. The controller (8) uses the correction amount AAd, corrects the value W of the load in the bucket (3c) at the current posture of the work machine (3), and acquires a load value WP after correction.
