Title:
WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2020/194878
Kind Code:
A1
Abstract:
In the case of a bucket 10 being grounded on soil, an operation signal is output or corrected so that the relative angle of the bucket 10 with respect to a target face is maintained if the distance D between the bucket 10 and the target face 60 is equal to or less than a preset first threshold value D1; in the case of the bucket 10 not being grounded on soil, an operation signal is output or corrected so that the relative angle of the bucket 10 with respect to the target face 60 is maintained if the distance between the bucket 10 and the target face 60 is equal to or less than a preset second threshold value D2 set to be less than the first threshold value D1. Thus, control to maintain the angle of a work tool can be properly started.
