Patent ID: 8364333

Claim:
A hybrid-type working machine comprising: an engine that drives a hydraulic pump; a motor generator that assists the engine; a plurality of electric loads; an electric storage part that supplies electric power to the motor generator and the electric loads; and a control part that controls said engine, said motor generator, said electric loads and said electric storage part, wherein the control part includes a CPU to perform functions of: setting a priority to each of said electric loads; computing an available electric power, which can be supplied from said motor generator and said electric storage part to said electric loads; computing a total electric power amount by summing electric power amounts requested by said electric loads; and comparing said available electric power with said total electric power amount, and, when said available electric power is smaller than said total electric power amount, determining a distribution ratio of electric power amounts to be supplied to the respective electric loads based on said priority to limit the electric power amounts supplied to said electric loads, wherein said determining determines the distribution ratio so that no limitation is applied to the electric power amount to be supplied to one of said electric loads, of which one is given said priority indicating a highest priority, and wherein, when the electric power amount requested by said one of said electric loads given the highest priority is larger than the available electric power, said determining determines the distribution ratio so that the entire available electric power is supplied to said one of said electric loads given the highest priority.
