Title:
WORK MACHINE AND ACTUATOR CALIBRATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/090087
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a work machine and an actuator calibration system, wherein an actuator can be calibrated in a short time. In order to do so, this calibration device, when ordered to perform calibration of an actuator, orders a control device to transition to a calibration mode, during the calibration mode causes a command value of a regulator that controls a pump flow rate to vary according to a prescribed pattern while a direction control valve is held in a neutral position, and, after having ordered the control device to transition to the calibration mode, creates an update map in which measured values of the pump flow rate and the command values are associated, and uses the update map to update a conversion map.
