Engine control device of work machine and engine control method therefor

摘要

An engine control device is provided including: detection units for detecting a driving state of a work machine using a generator, target engine speed setting units for causing, on the basis of the driving state, a target engine speed set for a case where electric power generation by the generator is OFF to be the same as a target engine speed set for a case where the electric power generation by the generator is ON, and engine target output calculation units for calculating an engine target output during electric power generation OFF that can be output at most when the electric power generation by the generator is OFF, and calculates an engine target output obtained by adding an output corresponding to an electric power generation amount by the generator to the engine target output when the electric power generation by the generator is ON.

1. An engine control device of a work machine comprising:
a detection unit detecting a driving state of the work machine including a generator; a target engine speed setting unit setting, on the basis of the driving state, a target engine speed when electric power generation by the generator is OFF to be same as that when the electric power generation by the generator is ON; and an engine target output calculation unit calculating an engine target output during electric power generation OFF which is a maximum output when the electric power generation by the generator is OFF, and calculating another engine target output by adding an output corresponding to an electric power generation amount by the generator to the engine target output during electric power generation OFF when the electric power generation by the generator is ON.
