Vehicle and control method of vehicle

摘要

The catalyst smell reducing control in which the fuel cutoff is performed is not executed regardless of the catalyst smelling flag Fs1 equal to ‘1’ (step S140) when the vehicle speed V becomes less than the preset vehicle speed Vref (step S130) while the catalyst deterioration reducing control in which the fuel cutoff is prohibited is being executed (step S150). Such control prevents from executing the catalyst smell reducing control while the suspension of the catalyst deterioration reducing control and prevents performing the fuel cutoff after performing a fuel injection and performing the fuel injection again for a relatively short time in the internal combustion engine. Therefore, it is enabled to reduce an occurrence of a shock due to the temporal decline of the output torque from the internal combustion engine, and is thereby enabled to reduce a sense of incompatibility given to the driver or passenger by reducing the occurrence of the shock due to the execution of the catalyst deterioration reducing control and the catalyst smell reducing control.
