    • In hybrid construction machine employing a hydraulic motor and an electric motor for the driving of the swing structure, satisfactory operability of a combined operation of the swing structure and other actuators is secured irrespective of the operating status of the electric motor.A control device of the hybrid construction machine executes control selected from: hydraulic/electric complex swing control for driving the swing structure by total torque of the electric motor and the hydraulic motor when a swing operating lever device is operated; and hydraulic solo swing control for driving the swing structure by the torque of the hydraulic motor alone when the swing operating lever device is operated. The control device controls drive torque or driving force of each of the electric motor, the hydraulic motor and a second hydraulic actuator so that the relationship between the position or the speed of the second hydraulic actuator and the swing angle or the swing speed of the swing structure in the combined operation when the swing operating lever device and a second operating lever device are operated at the same time during the hydraulic/electric complex swing control is substantially identical with the relationship in the combined operation during the hydraulic solo swing control.
    • 在使用液压马达和用于驱动摆动结构的电动机的混合动力施工机械中,无论电动机的运行状态如何,均可确保摆动结构和其它致动器的组合操作的可操作性。 混合动力施工机械的控制装置执行选择的控制装置:当操作摆动操作杆装置时,通过电动机和液压马达的总转矩来驱动摆动结构的液压/电动复合摇摆控制; 以及当操作摆动操作杆装置时单独通过液压马达的扭矩驱动摆动结构的液压独奏摆动控制。 控制装置控制电动机,液压马达和第二液压致动器中的每一个的驱动扭矩或驱动力,使得第二液压致动器的位置或速度与摆动角度或摆动摆动速度之间的关系 在液压/电气复合体摆动控制期间当摆动操作杆装置和第二操作杆装置同时操作时的组合操作中的结构与液压独奏摇摆控制期间的组合操作的关系基本相同。
