An object of the present invention is to provide a construction machine that can reduce particulate matter (PM) or nitrogen oxide (NOx) discharged from an internal combustion engine mounted on the construction machine. The construction machine 200 includes a diesel engine 101 controlled based on a torque command, an electric motor 102 mechanically connected to the diesel engine, an electric energy storage device 111 that supplies electric power to the electric motor, and a hydraulic pump 103. The construction machine performs work by driving the hydraulic pump using the diesel engine and the electric motor. A speed control device 118 controls a speed of the electric motor 102 based on a speed command. A torque limiter 115 obtains the torque command having a rate of change with time limited based on a torque target. |
