Abstract
A control system for controlling both: an engine having a plurality of cylinders, a plurality of intake ports formed individually for the cylinders, a plurality of intake valves for opening or closing the intake ports individually for the cylinders, and a control valve for opening or closing one of the intake ports of each of the cylinders; and an automatic transmission connected to the engine. The control system comprises: a valve controller for opening the control valve, when an engine load is high, and for closing the control valve when the engine load is low: an air/fuel ratio controller for making an air/fuel ratio when the control valve is closed higher than that when the control valve is open; and a shift inhibitor for inhibiting the shift in the automatic transmission till a predetermined time period elapses after the switching of the control valve.
