Abstract
An integrated control method is provided for an engine and a transmission and the method is capable of integrally controlling the engine and the transmission, based on a control correlation between the engine and the transmission. This method determines a target engine operating point reflecting a driving state of a vehicle and a driver's intention to accelerate, in an integrated control map having an engine control area and a transmission control area. The method calculates a target shift ratio based on the target engine operating point, thus being capable of significantly saving a man-hour required to set a map as compared to a conventional control method in which an engine torque map and a shift pattern map are individually set, and improving fuel efficiency.
