PURPOSE: A hybrid driving apparatus of a vehicle is provided to reduce energy loss due to electric energy flow or change by fixing the first motor generator and allowing the second motor generator to idle. CONSTITUTION: A hybrid driving apparatus of a vehicle comprises a planetary gear mechanism(1), first and second motor generators(3,5), an engine(7), a first brake(11), a second brake(13), and an output shaft(15). The planetary gear mechanism comprises at least four rotating elements. The first and the second motor generator are connected to two rotating elements of the planetary gear mechanism, respectively. The rotation restriction state of the engine can be independently varied by the two rotating elements. The first and the second brake can change the rotation restriction state of one of the rotating elements to a fixed member. The output shaft is connected to the rotating element of the planetary gear mechanism which is connected to the second motor generator.
