PROBLEM TO BE SOLVED: To obtain good drivability by suppressing gear shift shock at the time when down-shift is performed during a lockup clutch operation at the cutting of fuel for speed reduction, and to enlarge a fuel cutting region. SOLUTION: When down-shift is performed during the lockup clutch operation at the cutting of fuel for speed reduction, a throttle opening increase amount DTH is set according to an engine revolution NE (S8), and a throttle opening indication value TH for an electronic control throttle is calculated by adding the throttle opening increase amount DTH to the throttle opening reference value THI set based on an accelerator pedal actuating amount Sap. Thereby, since a throttle valve is forcibly opened according to the engine revolution when performing down-shift, a negative engine torque caused by a pump damage or the like is reduced, and thus a shift shock can be alleviated. |
