Abstract
A control system for controlling both a lean combustion engine equipped with a swirl control valve and an automatic transmission. The control system includes a shift detector for detecting that a shift is being executed in the automatic transmission and a valve control inhibitor for inhibiting the switching the ON/OFF state of the swirl control valve in the course of the shift in the automatic transmission. A shift inhibitor inhibits the shift for a constant time period in case the ON/OFF state of the swirl control valve is switched. A regulation level changer changes the regulation level of the oil pressure of the automatic transmission in accordance with the ON/OFF state of the swirl control valve.
