| description | A construction machine (1) includes an engine (15), a loadestimationunit (45) that estimates a pump power absorption, aregeneration/poweringpower demand calculationunit (46) that calculates a regeneration/powering power demand according to a state of charge in an electrical storage device (34), an engine power demand calculation unit (47) that calculates an engine power demand based on the power absorption and regeneration/powering power demand, and a motor generator control unit (48) that performs rotational speed control or torque control. The control unit (48) includes a control switching unit (48A) that switches the rotational speed and the torque control according to the engine power demand and the rotational speed of the engine (15). The control switching unit (48A) switches from the torque control to the rotational speed control when during performance of the torque control, the engine power demand increases and the rotational speed of the engine (15) becomes lower than a predetermined rotational speed. |
