Abstract
An engine control method includes determining an intention of a driver for acceleration during vehicle traveling, stopping fuel supply to an engine when a determination is made that the driver does not have the intention for acceleration, detecting a speed of the vehicle during inertial traveling, with fuel supply to the engine kept stopped, permitting restart of the engine when a determination is made that the driver has the intention for acceleration after stopping the fuel supply to the engine, prohibiting the restart of the engine until an engine rotational speed drops to or below a predetermined rotational speed threshold, even when the restart of the engine is permitted, restarting the engine after the engine rotational speed drops to or below the predetermined rotational speed threshold, and changing the rotational speed threshold depending on the detected speed. The rotational speed threshold increases with increase in the detected speed.
