Low idle control system of construction equipment and automatic control method thereof

Abstract

The present disclosure discloses a low idle control system of construction equipment and an automatic control method thereof. The low idle control system of construction equipment includes: a front angle change sensing means which detects an operation of at least a part of a front unit through changes in an angle; a controller which is electrically connected to the front angle change sensing means, determines whether to enter an auto idle state by receiving an output signal that is transmitted from the front angle change sensing means, and generates an rpm control signal corresponding to the result of the determination on whether to enter the auto idle state; and an ECU which controls the rpm of an engine by receiving the rpm control signal outputted from the controller. The present disclosure is capable of implementing an effective auto idle function by more accurately recognizing a state of using equipment.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a Section 371 National Stage Application of International Application No. PCT / KR2011 / 009920, filed Dec. 21, 2011 and published, not in English, as WO2012 / 087020 on Jun. 28, 2012.FIELD OF THE DISCLOSURE[0002]The present disclosure relates to a low idle control system of construction equipment and an automatic control method thereof, and more particularly, to a low idle control system of construction equipment and an automatic control method thereof, capable of implementing an effective auto idle function by accurately recognizing a state of using equipment.BACKGROUND OF THE DISCLOSURE[0003]In general, there are excavators, wheel loaders, and the like as construction equipment. The excavators perform various operations such as operations of excavating, leveling the ground, compacting the ground, lifting heavy objects, and the like. The excavator has a working device including a boom, an arm, and a bucket, and work of the ...

AI Technical Summary

Benefits of technology

The present invention provides a system and method for controlling the idle of construction equipment. The system uses sensors to detect the use of the equipment and controls the engine to automatically idle. This helps to save fuel and reduce emissions. The system also includes an angle change sensor to detect changes in the position of the front unit, which improves the accuracy of identifying when the equipment is being used. Overall, the system provides a more efficient and effective method for controlling idle in construction equipment.

Problems solved by technology

However, because a variation in pressure of the front unit is very small when the no-load operations are performed, it may be recognized that the equipment does not work.

However, the aforementioned no-load operation is frequently converted directly into a load operation, and in this case, because the auto idle state needs to be suddenly released, there is a problem in that the engine is stopped (engine stall), or an increase in output of the engine is delayed.
