Apparatus for controlling construction equipment engine and control method therefor
The present invention relates to an apparatus for controlling a construction equipment engine and a control method therefor. The apparatus for controlling a construction equipment engine comprises: a vehicle control unit for controlling construction equipment; a lever for generating a first signal when the construction equipment is converted into an operating state or a neutral state; an auto idle switch for generating a second signal when an auto engine idle mode is on; an engine for generating power; and an engine control unit for controlling the engine according to an engine revolution per minute (RPM) requested by the vehicle control unit, generating engine torque information for the engine and supplying the information to the vehicle control unit. If the lever is converted into the neutral state while being in a state where the second signal is activated, the vehicle control unit controls the engine control unit to reduce the RPM of the engine to the step RPM (RS) corresponding to a first speed-reducing step; if the first speed-reducing step is maintained for a predetermined period of time, the vehicle control unit controls the engine control unit to further reduce the RPM of the engine to the idle RPM (RI) corresponding to a second speed-reducing step; and if the lever is converted into the operating state while the second speed-reducing step is being maintained, the vehicle control unit controls the engine control unit to recover the RPM of the engine (20) to the step RPM (RS) corresponding to the first speed-reducing step.
