Abstract: A control system controls a construction machine having a work machine including a tilting bucket. The control system includes: a first acquisition unit configured to acquire dimension data; a second acquisition unit configured to acquire external shape data of the bucket; a third acquisition unit configured to acquire target excavation landform data indicating a target excavation landform that is a two-dimensional target shape of an excavation object on a work machine operation plane perpendicular to a bucket axis; a fourth acquisition unit configured to acquire work machine angle data; a fifth acquisition unit configured to acquire tilt angle data indicating a turning angle of the bucket; and a calculation unit configured to obtain two-dimensional bucket data indicating an external shape of the bucket on the work machine operation plane on the basis of the dimension data, the external shape data, the work machine angle data, and the tilt angle data.

Abstract: Provided is a control system of a construction machine provided with working equipment including an arm and a bucket configured to rotate around each of a bucket axis and a tilt axis orthogonal to the bucket axis with respect to the arm. The control system includes: an angle determination unit configured to determine a tilt angle indicating an angle of a specific portion of the bucket around the tilt axis so that a target construction topography indicating a target shape of an excavation object and the specific portion of the bucket become parallel to each other; and a working equipment control unit configured to control a tilt cylinder configured to rotate the bucket around the tilt axis on the basis of the tilt angle determined by the angle determination unit.
