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.

Abstract: A distance obtaining unit obtains the distance between a work implement and a design terrain. A work aspect determining unit determines a work aspect by the work implement. A limit velocity deciding unit limits the velocity of the work implement when the distance between the work implement and the design terrain becomes smaller. When the work aspect is surface compaction work and the distance between the work implement and the design terrain is within a first range of at least a portion that is equal to or less than a predetermined first distance, the limit velocity deciding unit increases the limit velocity of the work implement in comparison to when the work aspect is an aspect of a work other than surface compaction, or cancels the limiting of the velocity of the work implement.
