PROBLEM TO BE SOLVED: To prevent stiffness from being felt caused by fuel cut in reacceleration as well as to improve fuel consumption efficiency by fuel cut, in a hybrid vehicle provided with an engine and an electric motor as power sources for vehicle traveling and to travel by selectively using the engine and the electric motor according to the operating conditions. SOLUTION: When it is judged that a vehicle is in the deceleration traveling state in steps SA1 to SA3, fuel supply in relation to an engine is stopped in a step SA4. Whether the vehicle is in the driving state in which it travels by taking an electric motor as a power source or not is judged in a step SA8. If YES, a first clutch CE1 is released in a step SA10 to release the engine from a driving system, while, if NO, namely, if the vehicle is in the driving range in which it travels by taking only the engine as a power source, the engine is forcibly rotated according to the vehicle traveling state by maintaining the engaging state of the first clutch CE1 . |
