Abstract

Abrupt deceleration of a vehicle is detected based on a depression amount or a depression speed of a brake pedal. If abrupt deceleration of the vehicle has been detected during fuel-cut control, a command is issued to make forcible restoration of control out of the fuel-cut control. Then a lock-up clutch is disconnected and fuel injection for an engine is resumed so as to restore a rotational speed of the engine. As a result, the engine is prevented from stalling due to the undershooting of the engine rotational speed.
