SWING CONTROL APPARATUS AND METHOD OF CONSTRUCTION MACHINERY
First Claim
1. A swing control apparatus for a construction machine comprising:
- a start position estimation unit calculating or estimating an optimum stop starting position for stopping an upper swing structure in a stop position (or at a stop angle) set by a user using the set stop position (or the set stop angle);
a stop target position calculation unit calculating a stop target position using a current position of the upper swing structure and the calculated or estimated optimum stop starting position when a user'"'"'s stop command is input; and
a swing motor position control unit controlling a position of a swing motor so that the upper swing structure is stopped in the calculated stop target position.

Abstract
A swing control apparatus and a swing control method for a construction machine are provided. The swing control apparatus includes a start position estimation unit, a stop target position calculation unit, and a swing motor position control unit. Even if an operator releases a lever or commands a stop at different times, an upper swing structure of the construction machine (for example, excavator) can be stopped within a predetermined range, and thus the inconvenience caused by an additional driving operation, which is required as the stop position differs according to the time point where the stop command starts, can be solved.
