A control method for a hybrid work machine including an internal combustion engine which includes an exhaust gas treatment device, a generator motor which is connected to an output shaft of the internal combustion engine, and an electrical storage device which stores electric power generated by the generator motor or supplies electric power to the generator motor, the control method for the hybrid work machine includes: determining whether the hybrid work machine is in a regeneration state in which a regeneration is performed by the exhaust gas treatment device; setting a threshold value for starting a generation of power by the generator motor to a minimum generation torque as a lower limit value when it is determined that the exhaust gas treatment device performs a regeneration; and controlling the generator motor based on the set threshold value.
