Claim 23:
24. A system including a work machine, the system comprising:
a vehicular body;
a plurality of wheels attached to the vehicular body;
a work implement including a bucket, a boom that raises and lowers the bucket, and a work tool cylinder that drives at least one of the bucket and the boom;
a traction sensor that senses information about traction of the plurality of wheels;
a cylinder pressure sensor that senses cylinder pressure of the work tool cylinder; and
a controller that calculates traction pressure included in the cylinder pressure based on the information about the traction sensed by the traction sensor, subtracts the traction pressure from the cylinder pressure to correct the cylinder pressure to calculate corrected pressure of the work tool cylinder, and calculates an instantaneous load in the bucket based on the corrected pressure.
