  • Patent number: 10766480
    Abstract: A hybrid construction machine includes: a motor generator system connected to an internal combustion engine and performing a motor generator operation; an electric power accumulation system connected to the motor generator system; a load drive system connected to the electric power accumulation system and being driven electrically; an abnormality detection part equipped to the motor generator system, the electric power accumulation system and the load drive system; and a main control part determining whether an abnormality has occurred based on a detection value of the abnormality detection part. When the abnormality determination part determines that an abnormality has occurred, the main control part stops a drive of a drive system in which the abnormality is detected in the load drive system.

  • Patent number: 8818648
    Abstract: A hybrid construction machine includes a hydraulic pressure 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 work element driven by an electric motor. A superordinate control unit generates a control command which controls drive of the hydraulic pressure work element and the electric-motor work element. A subordinate control unit controls drive of the hydraulic pressure work element and the electric-motor work element based on the control command generated by the superordinate control unit. The subordinate control unit monitors an error in the superordinate control unit.
