Zusammenfassung:A hybrid construction machine includes an engine (11), a hydraulic pump (14) configured to be driven by the engine (11), an electric motor (12) configured to assist the driving of the engine (11), and a generator (12) configured to be driven by the engine (11) to generate power. The number of revolutions of the engine (11) is caused to vary in accordance with the size of a load on the engine (11). In response to a decrease in the load requested of the engine (11), the engine (11) is decelerated by causing the generator 12 to generate power. In response to an increase in the load requested of the engine (11), the engine (11) is accelerated by assisting the engine (11) by driving the electric motor (12).
