HYBRID WORKING MACHINE AND METHOD OF CONTROLLING SAME

摘要

A control unit of a hybrid working machine calculates an actual hydraulic pressure output from the output of an engine (30) and the output of a motor generator (34), and calculates an assumed hydraulic pressure output (Win) as an output of a hydraulic pump (21) using a predetermined algorithm. The control unit corrects a hydraulic pump characteristic parameter used in the predetermined algorithm based on an assumed hydraulic pressure output error being a difference between an assumed hydraulic pressure output and an actual hydraulic pressure output, calculates an assumed hydraulic pressure correction output, and controls the motor generator (34) based on the assumed hydraulic pressure correction output.
