Title:
HYBRID CONSTRUCTION MACHINE
Document Type and Number:
WIPO Patent Application WO/2010/064625
Kind Code:
A1
Abstract:
A hybrid construction machine includes a hydraulic work element driven by hydraulic pressure generated by driving power of an internal combustion engine or a motor-generator, and also includes an electric motor-driven electric work element. A superordinate control section generates a control command for controlling drive of the hydraulic work element and the electric work element. A subordinate control section controls drive of the hydraulic work element and the electric work element on the basis of the control command generated by the superordinate control section. The subordinate control section monitors an abnormality of the superordinate control section.
