PURPOSE:To prevent deceleration shock due to slip control by setting an opening of a throttle valve at a magnitude obtained through subtraction of a specified amount from the maximum opening of the throttle valve for a specified period of time from the time when the rotating acceleration of a combustion engine remains below a specified value and the rotating acceleration of a driving wheel becomes above a specified value. CONSTITUTION:An opening correcting means M12 judges that the upshift is completely carried out by an automatic change gear M3 when the rotating acceleration of a combustion engine M1 calculated by an engine acceleration calculating means 10 remains below a specified value and the rotating acceleration of a driving wheel M2 calculated by a driving wheel calculating means M11 becomes above a specified value. For a specified period of time, an opening of a throttle valve M6 driven by a control means M7 is set at a magnitude obtained by subtracting a specified amount from the maximum opening of the throttle valve M6 memorized by an opening memory means M9. Thus, the deceleration shock can be prevented by setting the opening of the throttle valve M6 at a magnitude obtained by subtracting a specified value from the maximum opening directly before abrupt reduction caused by a peak of driving wheel speed. |
