PROBLEM TO BE SOLVED: To solve or relax the jerky movement of a vehicle generated during traveling at low speed. SOLUTION: In fuel cut control over an internal combustion engine, when an accelerator openingθis set to a threshold or below, it is determined as one of fuel cut start conditions. When a variation or a rate of changeΔθ/Δt per unit time in the accelerator openingθis below a predetermined value A, the threshold is set to a valueθ<SB>1</SB>smaller than a thresholdθ<SB>2</SB>when it is not below the predetermined value. Thereby, it becomes possible to reduce fuel cut start frequency when slightly depressing an accelerator pedal during the traveling at low speed and to avoid occurrence of the jerky movement due to frequency of fuel cut.
