PROBLEM TO BE SOLVED: To improve a fuel consumption by extending a time of fuel cutting control as long as possible by setting a return rotation speed as low as possible, an to a return rotation speed always reaching engine stall on the engine side in a control device of a hybrid vehicle, and to smoothly converge an engine speed to an idle rotation speed without uncomfortable feeling by performing assist control so as to keep the engine speed that does not cause the engine stall on the motor generator side. SOLUTION: This control device comprises a deceleration detecting means for detecting a deceleration state of the vehicle, and a fuel cut control means for performing the fuel cut control for stopping fuel supply to the engine only when a fuel cut performing condition is satisfied in decelerating vehicle, and for releasing the fuel cut control and resuming the fuel supply to the engine when the engine speed decreases to the set return rotation speed. |
