CONTROL SYSTEM FOR CONSTRUCTION MACHINE, CONSTRUCTION MACHINE, AND METHOD FOR CONTROLLING CONSTRUCTION MACHINE
First Claim
1. A control system for a construction machine including a work machine including:
- a boom rotatable about a boom axis relative to a vehicle main body, an arm rotatable about an arm axis parallel to the boom axis relative to the boom, and a bucket rotatable about a bucket axis parallel to the arm axis and about a tilt axis perpendicular to the bucket axis relative to the arm, the control system comprising;
a first acquisition unit configured to acquire dimension data including a dimension of the boom, a dimension of the arm, and a dimension of the bucket;
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 the bucket axis;
a fourth acquisition unit configured to acquire work machine angle data including a boom angle data indicating a turning angle of the boom about the boom axis, arm angle data indicating a turning angle of the arm about the arm axis, and a bucket angle data indicating a turning angle of the bucket about the bucket axis;
a fifth acquisition unit configured to acquire tilt angle data indicating a turning angle of the bucket about the tilt axis; 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
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.
