Position Control Apparatus and Method for Working Machine of Construction Machinery
First Claim
1. A position control apparatus for a working machine of a construction machinery, comprising:
- a boom driving unit for driving a boom;
a bucket driving unit for driving a bucket;
a working tool manipulating part for generating a manipulation signal for driving the boom driving unit and the bucket driving unit;
a kick-down switch for generating a kick-down signal for lowering a gear stage; and
a controller for, if the kick-down signal is generated by the kick-down switch and the manipulation signal is generated by the working tool manipulating part, outputting a control signal to the boom driving unit and the bucket driving unit to move the boom and the bucket to a preset position.

6. A position control apparatus for a working machine of a construction machinery, comprising:
-
a boom driving unit for driving a boom; a bucket driving unit for driving a bucket; a working tool manipulating part for generating a manipulation signal for driving the boom driving unit and the bucket driving unit; a manipulation unit for changing the boom and the bucket to a preset posture; and a controller for outputting a control signal to the boom driving unit and the bucket driving unit such that, if a manipulation signal of the manipulation unit is input, the bucket is automatically moved to a position close to the ground surface in parallel to the ground surface by lowering the boom and changing a posture of the bucket. - View Dependent Claims (7, 8)

9. A position control method for a working machine of a construction machinery for controlling positions of a boom and a bucket, the method comprising:
-
(a) if a kick-down signal is input, determining whether or not a boom-down signal is input; (b) if the determination result of (a) step shows that the boom-down signal is not input, outputting the kick-down signal to a transmission control unit; and (c) if the determination result of (a) step shows that the boom-down signal is input, moving the boom and the bucket to a preset position without outputting the kick-down signal to the transmission control unit.
