Title:

SWING CONTROL APPARATUS AND METHOD OF CONSTRUCTION MACHINERY

Document Type and Number:

WIPO Patent Application WO/2012/008627

Kind Code:

A1

Abstract:

The present invention relates to a swing control apparatus and method of construction machinery including a start position estimation unit, a stop target position calculation unit, and a swing motor position control unit. An upper swing body of construction machinery (e.g., a digger) may be stopped within a predetermined range even though a driver releases a lever or gives a stop command at time points different from each other. Thus, it may prevent the driver from performing an additional driving operation because the stopped position is changed according to time points at which the stop command starts.
