PURPOSE:To reduce the speed change shock without incurring the rise of the exhaust temperature by correcting the quantity of fuel supplied into an internal combustion engine to the increased quantity side, when the ignition timing is corrected to the delayed angle side in the speed change of an automatic transmission for vehicle. CONSTITUTION:When speed change is performed by an automatic transmission M2 which performs the torque transmission from an internal combustion engine M1 to a driving wheel M3, an ignition timing correcting means M4 corrects the ignition timing of the internal combustion engine M1 which is set by other treatment further to the delay angle side, and the speed change shock is reduced. At the same time, a fuel correcting means M5 corrects the quantity of fuel supplied to the internal combustion engine M1 which is set by other treatment further towards the increased quantity side, and the rise of the exhaust temperature generated by the delay angle treatment is suppressed. Further, since the degree of the reduction of output due to the delayed angle of the ignition timing is larger than that of the increase of output due to the increased quantity of fuel, speed change shock can be reduced sufficiently.
