Title:

HORSEPOWER CONTROL SYSTEM OF A HYBRID EXCAVATOR AND CONTROL METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2012/005391

Kind Code:

A1

Abstract:

Disclosed are a horsepower control system of a hybrid excavator and a control method therefor which controls the driving of a generator driver or a swing motor driver with a swing power ratio of 1 and a hydraulic power ratio of 1 in a first operation mode, and a swing power ratio of r (a user set value) and a hydraulic power ratio of 1 - r in a second operation mode. When the power required by the user is fully used, energy from an energy storage is used to maximize work capacity. When the total horsepower used is limited to the range of horsepower available, the limited use of the driving device is at a level of horsepower similar to that of a typical system, thereby minimizing fuel consumption.
