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.
Claims15
A device for integrally controlling an engine and an automatic transmission in a vehicle, comprising:
- supercharging means for selectively continuously or gradually introducing boost pressure to said engine;
- means for detecting intake air temperature;
- and
- means for increasing or decreasing oil pressure in a hydraulic control device of said automatic transmission in association with at least the values of said intake air temperature and said boost pressure selectively introduced by said supercharging means.
