摘要： There is a need to further improve the fuel consumption of a vehicle. There is provided a vehicle control device mounted on a vehicle having: an engine; a battery that is chargeable with an amount of electric power generated by a generator which is driven with power of the engine; and auxiliary machinery that are operated with electric power of the battery. The vehicle control device comprises an idle reduction controller, an SOC detector, a current value obtaining section, a current correcting section, an idle reduction capacity setting section and a remaining capacity controller. The current correcting section comprises: a smoothing process section that makes the current value obtained by the current value obtaining section subject to a smoothing process (S160); a specific auxiliary machine operation detecting section that determines whether a specific auxiliary machine, which is included in the auxiliary machinery and is likely to have a temporary abrupt change of the current value, is in an operating state (step S140); and a current change suppressing section that suppresses an effect of a latest current value obtained by the current value obtaining section, in the smoothing process, when the specific auxiliary machine is determined to be in the operating state (S180).

摘要： 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.
