Abstract
A distance calculation unit calculates a bucket distance that is a distance between a point on a bucket and a target design surface representing a target shape of an excavation target. An intervention control unit calculates an intervention control amount to suppress a speed of work equipment such that the bucket does not intrude on the target design surface based on the bucket distance. An attachment control unit calculates an attachment control amount to rotate the bucket around an attachment axis such that an edge of the bucket and the target design surface approach each other in a parallel state. An attachment limiting unit limits rotation of the bucket around the attachment axis such that the bucket distance is not increased by a movement of the work equipment based on the intervention control amount and the attachment control amount.
