Abstract
A transmission system may include a planetary gear set disposed on an input shaft receiving power of an engine, two input gears connected respectively to two rotation elements among three rotation elements of the planetary gear set, first and second motor/generators disposed on an intermediate shaft and a connecting shaft disposed in parallel with the input shaft, two intermediate gears connected respectively to first and second rotors of the first and second motor/generators, a brake selectively connecting the first rotor of the first motor/generator to a transmission housing, and two output gears fixedly disposed on an output shaft disposed in parallel with the intermediate shaft and transmitting power transmitted through one input gear of the two input gears and/or one intermediate gear of the two intermediate gears to a final reduction gear of a differential apparatus.
