Title:
CONTROL DEVICE FOR CONSTRUCTION MACHINE AND CONSTRUCTION MACHINE EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2023/140092
Kind Code:
A1
Abstract:
A control device (1A) comprises a drive unit (21S, 5), an attitude information acquisition unit (31), and a control unit (50). The control unit (50) calculates the barycentric velocity of a work device (20) on the basis of the attitude information of the work device (20) detected by the attitude information acquisition unit (31), and meanwhile calculates a target barycentric velocity that is a target value of the barycentric velocity on the basis of the difference between a ground work that the work device (20) provides to the ground and a target ground work, and inputs a command value with feedback correction to the drive unit (21S, 5) such that the barycentric velocity approaches the target barycentric velocity.
