Abstract
A device integrally controls an engine having a supercharger and an automatic transmission. More specifically, boost pressure to the engine can be selectively introduced continuously or gradually, and oil pressure in a hydraulic control device of the automatic transmission is increased or decreased in accordance with the selected value of the boost pressure and an intake air temperature value. As a result, shift shock is low irrespective of output fluctuations of the engine due to a change in the boost pressure to and intake air temperature of the engine, and moreover, durability of the frictionally engaging devices is achieved.
