Abstract
In a vehicle engine, when an accelerator pedal is released and a vehicle speed has decreased after fuel injection by a fuel injector has stopped, a controller restarts fuel injection. An engine rotation speed decrease rate immediately prior to restarting fuel injection is calculated, and a restart fuel injection amount is set which is larger the larger the decrease rate. In this way, the torque generated by the engine quickly recovers even during rapid deceleration, while during gradual deceleration, the generated torque increases gradually so that a torque shock does not occur.
