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.

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 co
