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.
