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 machine, 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 configured to generate output signals as a combined function of the kick-down signal and the manipulation signal such that, if the kick-down signal is generated by the kick-down switch and the manipulation signal is generated by the working tool manipulating part, the controller outputs a control signal to the boom driving unit and the bucket driving unit to move the boom and the bucket to a preset position, and such that if the kick-down signal is generated by the kick-down switch and the manipulation signal is not generated by the working tool manipulating part, the controller outputs the kick-down signal to a transmission control unit to lower a gear stage.

5. A position control apparatus for a working machine of 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 configured to output 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;
wherein the working tool manipulating part includes a boom manipulating part for generating the manipulation signal for driving the boom, and when the manipulation signal of the manipulation unit is input and a boom-down signal is input by the boom manipulating part, the controller automatically drives the boom and the bucket, and wherein when the manipulation unit is manipulated while the boom-down signal is not input, the controller is a kick-down switch for outputting a transmission adjusting signal to a transmission control unit and is installed on an upper surface of the boom manipulating part to be manipulated together with the boom manipulating part.
- a boom driving unit for driving a boom;
