Abstract
A control system for an engine with an automatic transmission, including an output reducing system for reducing an output of the engine by a predetermined quantity in a speed change operation of the automatic transmission, so as to suppress a speed change shock generated in the speed change operation; and an output reduction control system for controlling a start timing of operation of the output reducing system so as to make a timing when output reduction of the engine is completed by the output reducing system coincide with a start timing of an actual gear shift operation of the automatic transmission. Accordingly, the engine output is reduced in the speed change operation of the automatic transmission, and the speed change shock generated in the speed change operation can be greatly suppressed by making the timing when the output reduction of the engine is completed coincide with the start timing of the actual gear shift operation of the automatic transmission.
