A method of controlling a hybrid working machine having a hydraulic pump driven with an output of an engine and an output of a motor generator, comprising:
- calculating an input side power of the hydraulic pump, and
- controlling the output of the motor generator based on the calculated power.
A method of controlling a pump output of a hybrid working machine having a variable displacement hydraulic pump driven with an engine and having the engine assisted with a motor generator, comprising:
- controlling an output of the variable displacement hydraulic pump in accordance with a predetermined algorithm using an excess of the output of the variable displacement hydraulic pump determined by subtracting an output of the engine and an output of the motor generator from the output of the variable displacement hydraulic pump.
