ABSTRACT:
In controlling an internal combusion engine so as to temporarily decrease output torque thereof in relation to speed stage shifting of an automatic transmission connected therewith, input rotational speed of the automatic transmission is monitored so as to obtain first and second subsequent time points corresponding to traversing of first and second predetermined values of the input rotational speed along with change thereof due to the speed stage shifting of the transmission, and a control for decreasing engine output torque is triggered at the first time point, while the cancellation of the decreasing of engine output torque is triggered at a time point which is counted by a timer starting from the second time point.
