ABSTRACT:
In a system for integrally controlling an automatic transmission and an engine, an ignition timing is temporarily lagged during shifting to decrease an engine torque. The system comprises a detecting device for detecting the presence of a shifting condition; a delaying device for delaying the commencement of actual shifting for a predetermined time duration; and a performing device for performing a fuel increase immediately after the presence of the shifting condition is detected. As a result, a decrease in the engine torque due to ignition timing control is satisfactorily secured, while exhaust gas temperature is prevented from rising, whereby temperature in an exhaust system is precluded from raising beyond an allowable value.
