Abstract

The present invention provides a low idle control system of construction equipment and an automatic control method thereof. Said low idle control system of the construction equipment comprises: a front angle change sensing means (10) which senses an operation of at least a part of a front unit through changes in an angle; a controller (3) which is electrically connected with said front angle change sensing means (10), determines whether to enter an auto idle state by receiving an output signal that is delivered from said front angle change sensing means (10), and generates an rpm control signal corresponding to the result of said determination on whether to enter the auto idle state; and an ECU (4) which controls the rpm of an engine (5) by receiving the rpm control signal outputted from said controller (3). The invention understands the state of use of equipment more accurately, thereby implementing an effective auto idle function.
