<p>PROBLEM TO BE SOLVED: To provide a control device of a hybrid vehicle, which enables vibration to be suppressed, the vibration occurring when an internal combustion engine is stopped.SOLUTION: The control device is applied to a hybrid vehicle 1 in which a first MG 11 is connected to a sun gear S of a planetary gear mechanism 15, an internal combustion engine 10 is connected to a carrier C of the planetary gear mechanism 15 via a variable inertial fly wheel 17 and a dumper 18, and an output part 14 is connected to a ring gear R of the planetary gear mechanism 15. The control device performs engine stop control causing the first MG 11 to output torque so that engine speed of the internal combustion engine 10 decreases when the internal combustion engine 10 is stopped. During performing the engine stop control, the control device controls the variable inertial fly wheel 17 so that: the variable inertial fly wheel 17 switches to a high inertial state when an absolute value of the torque to be output from the first MG 11 is larger than a switching determination value; and the variable inertial fly wheel 17 switches to a low inertial state when the absolute value of the torque to be output from the first MG 11 is equal to or less than the switching determination value.</p> |
