Abstract
A control apparatus of a power transmission system is provided and includes an input shaft through which torque from an engine is input and first and second motor/generators. A planetary gear set is disposed on a line from the input shaft and an output shaft transmits torque from the planetary gear set and the second motor/generator to driving wheels. A battery supplies electricity to the first and second motor/generators and charges electricity generated therefrom. An HEV mode 1 in which an operation of a first brake and a second brake is released or an HEV mode 2 in which an operation of the second brake is operated is converted based on a mechanical maximum efficiency range, a required power of the engine, a speed ratio of a transmission, and an SOC of the battery.
