Abstract
[Object] When total power required by a hybrid construction machine increases above output power available from a driving source, power supplied to a rotation motor is restricted. [Means to Realize Object] Driving power from an engineis distributed to a hydraulic pumpand a generator. Electric power generated by the generatoris used to drive a rotation motor, and pressurized oil provided by the hydraulic pumpis used to drive a hydraulic machine. When both of the hydraulic machineand the rotation motorare simultaneously manipulated, the output power outputted by the engineand the required power required by the hydraulic machineand the rotation motorare detected. When the required power exceeds the output power, the torque or acceleration of the rotation motoris restricted to preferentially provide output power to the hydraulic machine
