Abstract
A measurement value acquisition unit acquires measurement values from a plurality of sensors. A posture calculation unit calculates a posture of an attachment with respect to a vehicle body based on the measurement values. An intervention control unit determines a virtual rotation axis based on the calculated posture of the attachment. An operation signal acquisition unit acquires an operation signal for operating the support portion from an operation device. An intervention control unit generates a control signal for the tilt rotator to rotate the attachment around the virtual rotation axis so that an axial direction of the virtual rotation axis in a global coordinate system is held and a design surface and teeth of the attachment are approximately parallel to each other, based on the calculated posture of the attachment and an operation amount indicated by the operation signal for operating the support portion. An output unit outputs the generated control signal.
