Abstract
A work vehicle includes a work implement and a controller. The work implement includes a vehicular body that travels in excavation, a boom pivotable with respect to the vehicular body, and a bucket pivotable with respect to the boom. The controller calculates a direction of a cutting edge of the bucket, determines a direction of movement of the cutting edge by an excavation operation such that an excavation angle between the calculated direction of the cutting edge of the bucket and the direction of movement of the cutting edge by the excavation operation keeps a predetermined angle, and causes the work vehicle to perform the excavation operation in the direction of movement.
