Title:
WORK VEHICLE AND DATA CALIBRATION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/087830
Kind Code:
A1
Abstract:
A work vehicle is provided with: an operation device (51) for operating a work machine: a valve for adjusting the flow rate of a working fluid that actuates the work machine (104); solenoid proportional control valves (61A, 61B) that are provided to a pilot oil path connecting a pilot hydraulic pressure source and a pilot chamber for the valve and that generate a command pilot pressure using the original pressure input from the pilot hydraulic pressure source as primary pressure; and a main controller (52) for outputting a command current that actuates the solenoid proportional control valves (61A, 61B) in accordance with operation of the operation device (51). The main controller (52) comprises a data table storage unit (91) in which data for predicting the operating speed of the work machine is stored and a calibration unit (83) that calibrates the data if the operation device (51) is operated.
