ABSTRACT:
An apparent gear ratio, namely G=N.sub.T /N.sub.O, is determined based on transmission input and output revolution speeds N.sub.T and N.sub.O which are detected by sensors. The apparent gear ratio is used to determine whether a shift operation is in progress or not. It is defined that the gear shift operation is in progress when the apparent gear ratio falls between one gear ratio before the shift operation and another gear ratio after the shift operation. The engine output torque is altered, therefore, when the apparent gear ratio falls between one and another gear ratios.
