PROBLEM TO BE SOLVED: To prevent bad deceleration feeling when control for prohibiting fuel cut at deceleration is performed to prevent catalyst from deteriorating under high temperature lean atmosphere. SOLUTION: When control for prohibiting fuel cut at deceleration is performed to prevent catalyst from deteriorating under higher temperature condition of catalyst even in deceleration condition, control for increasing deceleration force given to a vehicle is done simultaneously. For example, output of alternator using engine output is raised (step 203), or an air conditioner using engine output also is turned on. By turning on the brake for a vehicle equipped with ABS, or by performing downshift for an A/T(automatic transmission) vehicle, good deceleration feeling during fuel cut prohibiting can be maintained. |
