Abstract
A control system of a hybrid construction machine includes a main pump for discharging working fluid and driving an actuator, a regeneration motor driven by the working fluid discharged from the actuator through a first regeneration passage, a rotational electric machine drivable by the regeneration motor, and a regeneration passage switching valve having a tank communication position that allows the first regeneration passage to communicate with a tank when a flow-in amount of the working fluid inside the first regeneration passage into the regeneration motor exceeds a defined value.
Claims5
A control system of a hybrid construction machine, comprising:
- a main pump configured to discharge working fluid and drive an actuator;
