    摘要： A hybrid-type working machine includes a plurality of electric loads (21,23,25) and an electric storage part (19) supplying an electric power to a motor generator (12) and the electric loads (21,23,25). A priority setting part sets a priority to each electric load (21,23,25). A supply power computing part computes an available electric power, which can be supplied from the motor generator (12) and the electric storage part (19) to the electric loads (21,23,25). A total power computing part (54) computes a total electric power amount by summing electric power amounts requested by the electric loads (21,23,25). A power distributing part (60) compares the available electric power with the total electric power amount, and, when the available electric power is smaller than the total electric power amount, determines a distribution ratio of electric power amounts to be supplied to the respective electric loads (21,23,25) based on the priority to limit the electric power amounts supplied to the electric loads (21,23,25).

    摘要： A control apparatus for a hybrid construction machine which can continue filter regeneration without impairing the operability as far as possible irrespective of a condition of a machine body or a power storage device is provided.
    The control apparatus for a hybrid construction machine includes an engine, a motor generator driven by the engine and capable of generating electric power, a hydraulic pump driven by total torque of the engine and the motor generator, a power storage device, an inverter, a filter that collects a particulate material in exhaust gas of the engine, and a control section that outputs a command signal for controlling powering operation or regeneration operation of the motor generator. The control apparatus further includes a powering operation limitation section that inputs thereto an ordinary torque command for the motor generator calculated by a torque command value calculation section and a demand signal for regeneration of the filter decided by a filter regeneration decision section and calculates the command signal in response to the input signals. The powering operation limitation section calculates, when the demand signal for regeneration of the filter is available, a command signal for limiting the powering operation of the motor generator.

    摘要： A motor generator (27) is connected mechanically to an engine (21) and a hydraulic pump (23). The hydraulic pump (23) delivers pressurized oil to cylinders (11D) to (11F) in a working mechanism (11), a traveling hydraulic motor (25) and a revolving hydraulic motor (26). The revolving hydraulic motor (26) drives a revolving device (3) in cooperation with a revolving electric motor (33). The motor generator (27) and the revolving electric motor (33) are connected electrically to an electricity storage device (31). An HCU (36) sets a target electricity storage rate (SOC0) of the electricity storage device (31) and a pump output limit (POLO) of the hydraulic pump (23) corresponding to a mode selected by a mode selection device (38). The HCU (36) controls the engine (21), the motor generator (27), the revolving electric motor (33) and the electricity storage device (31) corresponding to the target electricity storage rate (SOC0) and the pump output limit (POLO).
