Work machine, system including work machine, and method for controlling work machine

4:

• A system comprising a work machine including:
• a work implement having a boom, an arm attached to a leading end of the boom, and a bucket attached to a leading end of the arm;
• and
• a controller obtaining a load value within the bucket;
• obtaining a load value within the bucket when the work implement has a basic attitude, as a reference value, and a load value within the bucket when the work implement has an attitude different from the basic attitude, as a comparison value;
• generating correction data according to an attitude of the work implement beforehand, based on the reference value and the comparison value;
• sensing a current attitude of the work implement;
• calculating a correction amount of a load value within the bucket when the work implement has the current attitude, based on the correction data;
• and obtaining a corrected load value by correcting the load value within the bucket when the work implement has the current attitude using the correction amount.

• obtaining a load value within the bucket when the work implement has a basic attitude, as a reference value, and a load value within the bucket when the work implement has an attitude different from the basic attitude, as a comparison value;
• and
• generating correction data according to an attitude of the work implement, based on the reference value and the comparison value.
