ABSTRACT:
Fuel is cut off in the deceleration of a vehicle to improve efficiency of fuel consumption. Rotational speed of an engine in the resumption of fuel supply in the completion of the fuel cut-off is set to a value smaller than that otherwise set when a brake device is operated or the vehicle speed is higher than a predetermined value. While the torque of the engine varies abruptly to produce impact when the fuel cut-off is completed, passengers have a slight feeling of impact while the vehicle is being braked and travelling with high speed. Thus, while the feeling of impact is reduced, a period of fuel cut-off is increased to improve further the efficiency of fuel consumption and others.
