Abstract
A hybrid vehicle driving device includes: a first differential mechanism connected to an engine and transmitting a rotation of the engine; a second differential mechanism connecting the first differential mechanism and a drive wheel; engagement devices changing a speed of the first differential mechanism; and a valve arranged in a hydraulic circuit and regulating the engagement devices from simultaneously engaging. The second differential mechanism includes a first rotation element connected to an output element of the first differential mechanism, a second rotation element connected to a first rotating machine, and a third rotation element connected to a second rotating machine and the drive wheel. The valve regulates the engagement devices from simultaneously engaging at a time of traveling with the engine, and tolerates the engagement devices from simultaneously engaging at a time of traveling with the first rotating machine and the second rotating machine.
