Abstract
Providing a control device of a hybrid vehicle capable of reducing a rattling noise without changing an engine rotation speed. If the second electric motor torque Tis within the rattling noise occurrence region G, the engine rotation fluctuation suppression control (at least one of the EGR amount suppression control, the self-EGR amount suppression control, the lean-burn control, and the ignition delay control) is provided to suppress the engine rotation fluctuations as compared to during normal running while the second electric motor torque Tis out of the rattling noise occurrence region G and, therefore, the engine rotation fluctuations can be suppressed to reduce the a rattling noise without changing an engine rotation speed N. Thus, the rattling noise can be reduced without giving an uncomfortable feeling to a user due to a change in the engine rotation speed N.
