Document Type and Number:
WIPO Patent Application WO/2016/084421
Kind Code:
A1
Abstract:
A hybrid construction machinery control system (100, 200) comprises a hydraulic pump (26, 27), a regenerative motor (46), a rotating electrical device (48) that is connected to the regenerative motor (46), a storage battery (24) that accumulates power generated by the rotating electrical device (48), an assist pump (47) that is provided on the same shaft as the regenerative motor (46) and can supply a working fluid to a fluid pressure actuator (31) by being driven by the rotating electrical device (48), and a load adjusting unit (40, 41) that varies the assist pump (47) load in accordance with the state of the storage battery (24).
