Patent attributes
In a hybrid driving apparatus, a gear mechanism (3) having a first rotating element (7), a second rotating element (4) and a third rotating element (5) is provided, and a first driving power source (2), a second driving power source MG1 and a third driving power source MG2 are linked to the elements of the gear mechanism (3). The speed change ratio of the gear mechanism (3) can be altered. A driven member (18) to which the power output from an output element of the gear mechanism (3) is transmitted is provided. A first power transmission path (9) that connects the second driving power source MG1 to the driven member (18) is provided. A second power transmission path (17) that connects the third driving power source MG2 to the driven member (18) is provided. In this hybrid driving apparatus, at least one of the first power transmission path (9) and the second power transmission path (17) is provided with a transmission (19).
