Title:
LOADING WORK ASSISTANCE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/102298
Kind Code:
A1
Abstract:
This loading work assistance system performs a computation to predict a trajectory of a work apparatus in a finite time section using the output of a first position calculator of a loader, output of an orientation detector of the work apparatus of the loader, and a dynamic characteristic of the work apparatus. Upon determining that the work apparatus will not enter a prohibited area set on the basis of output of a second position calculator of a carrier, the system computes, on the basis of the result of a prediction computation, first input of the dynamic characteristic with which a distal end of the work apparatus approaches a target position set on the basis of the output of the second position calculator. Upon determining that the work apparatus will enter the prohibited area, the system computes second input of the dynamic characteristic with which the distal end targets and approaches a position that is closer to the target position than the position of the distal end of the work apparatus at a position different from the target position outside the prohibited area, and the system computes control input for controlling the operation of the loader on the basis of the first input and the second input of the calculation result.
