摘要： Both a hydraulic motor and an electric motor are provided for driving an upper swing structure. When the amount of electricity stored in a capacitor is appropriate, the upper swing structure is driven by both the hydraulic motor and the electric motor. When the amount of electricity stored in the capacitor exceeds an appropriate value, the mode is changed over to a mode in which the upper swing structure is driven only by the hydraulic motor, and an assist electric generation motor is assist-driven or engine-driven to thereby rapidly return the amount of electricity stored in the capacitor to an appropriate range. The capacity of the capacitor can be reduced, and the amount of electricity stored in the capacitor can be managed without losing the operability of swing motion.

Therefore, the actuator that malfunctions can easily be specified among the plurality of mounted actuators.

摘要： 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.
