Title:
CONTROL SYSTEM FOR HYBRID CONSTRUCTION MACHINE
Document Type and Number:
Japanese Patent JP2017210732
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve system efficiency of a hybrid construction machine.SOLUTION: A control system 100 for a hybrid construction machine compromises: a first and second main pumps 71, 72; a regenerative motor 88 that is rotatably driven by a circulated working fluid; a motor generator 91 connected to the regenerative motor 88; an assist pump 89 connected to the regenerative motor 88 and the motor generator 91; and a controller 90. The controller 90, when assist pump driving force La is larger than a driving force limit value Lmax, controls the assist pump 89 or the motor generator 91 so that the assist pump driving force La is equal to or smaller than the driving force limit value Lmax.SELECTED DRAWING: Figure 1
