Abstract
Official abstract text for this publication.
A driving device for hybrid vehicle provided with an engine, first and second electrical machines, a first and second differential mechanisms, and a switching device in which the first and second differential mechanisms are connected to each other through output rotational elements. The engine and the first and second rotating electrical machines are connected to different rotational elements out of rotational elements of the first and second differential mechanisms. The switching device switches between an independent mode and a four-element mode. In the four element mode, rotational elements connected to the engine, first and second rotating electrical machines, and the output rotational elements differentially rotate, and in an alignment chart in the four-element mode, any one of rotational elements connected to the first and second rotating electrical machines is located between a rotational element connected to the engine and the output rotational elements.
