In the present invention, neutral coasting, in which a vehicle is driven with the engine (12) running freely, is ended when a throttle position (&thetas;acc) reaches or exceeds a comparatively low first threshold (α). The vehicle is thus switched back to normal driving promptly, providing re-acceleration performance that meets the driver's expectations. On the other hand, free-run coasting, in which the engine (12) is stopped, is continued until the throttle position (&thetas;acc) reaches a comparatively high second threshold (&bgr;), but since the engine (12) is stopped, the driver expects improved fuel economy but does not have high expectations for re-acceleration performance. As such, fuel-economy improvement meeting the driver's expectations can be provided, and at the same time, the likelihood of making the driver feel as though something were amiss when free-run coasting is maintained up until the second threshold (&bgr;) is low. |
