Title:
CONTROL SYSTEM FOR HYBRID CONSTRUCTION MACHINE
Document Type and Number:
WIPO Patent Application WO/2011/099401
Kind Code:
A1
Abstract:
A controller determines whether the storage amount of a battery falls below a threshold value, and when the storage amount falls below the threshold value, controls an assist control mechanism on the basis of an assist correction factor to decrease the assist output of a sub pump, controls an engine controller on the basis of an engine rotation speed correction factor to increase the rotation speed of an engine to thereby increase the discharge amount of a main pump, and increases the rotation speed of the engine by an amount corresponding to a decrease in the assist output of the sub pump to increase the output of the main pump.
