Provided is a hybrid-vehicle control device that can reduce rattling sounds without engine RPM being changed. When a second electric motor torque (TM2) is in a rattling sound generation region (G), in comparison with normal traveling when the second electric motor torque (TM2) is not in the rattling sound generation region (G), engine revolution variation supression control (at least one form of control from among EGR amount suppression control, self EGR amount suppression control, lean burn control, and ignition retardation control) is performed so as to reduce rattling sounds by suppressing engine revolution variations without changing engine RPM (NE). Therefore, rattling sounds can be reduced while an uncomfortable sensation caused by a change in the engine RPM (NE) is not imparted to a user.
