HYBRID CONSTRUCTION MACHINE
First Claim
1. A hybrid construction machine comprising:
- a motor generator system connected to an internal combustion engine and performing a motor generator operation;
an electric power accumulation system connected to said motor generator system;
a load drive system connected to said electric power accumulation system and being driven electrically;
an abnormality detection part operatively connected to said motor generator system, said electric power accumulation system and said load drive system; and
a main control part determining whether an abnormality has occurred based on a detection value of said abnormality detection part,wherein, when said abnormality determination part determines that an abnormality has occurred, said main control part stops a drive of one of said motor generator system, said electric power accumulation system and said load drive system, in which the abnormality is detected.

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.
