Abstract

A hybrid working machine includes an engine, a motor generator connected to the engine, a variable displacement hydraulic pump configured to be driven to rotate with the output of the engine, and a control part configured to control the rotation speed of the engine and the variable displacement hydraulic pump. The control part is configured to determine the target rotation speed of the variable displacement hydraulic pump based on a hydraulic load and control the rotation speed of the engine using the target rotation speed.
