Engine idling control system of construction machine
An engine idling control method for a construction machine includes setting, by an E-ECU, an initial engine RPM as a starting mode (S mode) by receiving a signal from a V-ECU at the time of an engine startup; receiving, by the E-ECU, a first instruction via an engine speed control switch in a state other than an automatic idle mode; activating the automatic idle mode when the first instruction is not input to a machine during a certain time period, and setting the engine RPM as the starting mode (S mode); deactivating the automatic idle mode when a second instruction is input to the machine via the engine speed control switch while the automatic idle mode is activated; and calculating, by the V-ECU, an actual torque required for a pump for starting the machine according to the second instruction when the automatic idle mode is deactivated, and sending the actual torque to the E-ECU.
