Control device for hybrid work machine, hybrid work machine, and control method for hybrid work machine

摘要

A control device for a hybrid work machine stores a work machine, an internal combustion engine that supplies power to the work machine, a generator motor connected to an output shaft of the internal combustion engine, and electric power generated by the generator motor, or In a control device that controls a hybrid work machine having a power storage device that supplies electric power to the generator motor, a determination unit that determines whether the output of the internal combustion engine is limited, and at the time of output limitation, An assist restricting unit for restricting an assist operation for supplying electric power stored in the power storage device to the generator motor when increasing the rotational speed of the internal combustion engine based on a load of the work implement during work; and An engine control unit that controls the internal combustion engine and the generator motor in a state where the assist operation is limited.
