PROBLEM TO BE SOLVED: To provide a control unit reducing the fuel consumption of an engine in an operation method of an engine generator, and a dump truck for a mine including the control unit.SOLUTION: A control unit for an engine generator includes an engine, a generator driven by the engine and a motor driven by the output power of the generator. In the control unit for an engine generator, an engine speed is kept constant when a generator output is a threshold value Pth*-dGp or more and an engine speed is a threshold value Neth*-dNe or more, and an output command value to change the output of the generator is output to control the engine speed and the generator output.SELECTED DRAWING: Figure 19 |
