Abstract
A work equipment control device includes a bucket posture-determining unit, a working plane-determining unit, and a bucket control unit. The bucket posture-determining unit determines an angle of a bucket in global coordinates. The working plane-determining unit determines an angle of a working plane in the global coordinates indicating a target shape of an excavation object of work equipment. The bucket control unit controls the bucket such that a difference between the angle of the bucket and the angle of the working plane maintains a uniform angle.
