Title:
CONSTRUCTION EQUIPMENT CONTROL SYSTEM, CONSTRUCTION EQUIPMENT, AND CONSTRUCTION EQUIPMENT CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2020/158235
Kind Code:
A1
Abstract:
This construction equipment control system comprises: a design surface acquisition unit that acquires a design surface expressing a target shape to be constructed; an operation data acquisition unit that acquires operation data from an operation device for operating a work machine and a slewing body; a target value generation unit that generates a target value for a controlled variable associated with the tilting rotation of a tilting bucket and a target value for a controlled variable of the slewing body on the basis of the design surface and the operation data when the work machine and the slewing body are operated; a prediction unit that calculates a prediction value for the controlled variable associated with the tilting rotation of the tilting bucket and a prediction value for the controlled variable associated with the slewing of the slewing body on the basis of the target values and a prediction model for the work machine, and calculates drive amounts for controlling the work machine and the slewing body so as to maintain a distance between the prescribed position of the tilting bucket and the design surface and to maintain the attitude of the tilting bucket on the basis of the prediction values and the design surface; and a command unit that outputs control commands for controlling the work machine and the slewing body on the basis of the drive amounts.
