METHOD FOR CONTROLLING DRIVING FLOW OF WHEEL EXCAVATOR

Title:

METHOD FOR CONTROLLING DRIVING FLOW OF WHEEL EXCAVATOR

Document Type and Number:

WIPO Patent Application WO/2014/069759

Kind Code:

A1

Abstract:

The present invention includes the steps of: performing maximum flow control on a pump by controlling a proportional control valve which controls the maximum flow of a hydraulic pump after confirming the presence or absence of an abnormality in pump confluence control; receiving the flow pump flow value input controlled by the proportional control valve; confirming an error when the flow value that is inputted during the maximum flow control for the pump has an error; and compensating for the flow value by giving a weighted value to the confirmed error. Accordingly, driving fuel consumption can be reduced by lowering engine speed, and driving noise can be reduced.
