Abstract

Provided is a hybrid vehicle driving apparatus including: a power transmission mechanism which is connected to an engine and is able to output a rotation of the engine while changing the rotation speed; a differential mechanism which connects the power transmission mechanism and a drive wheel to each other; and a regulation device, wherein the differential mechanism includes a first rotation component which is connected to an output component of the power transmission mechanism, a second rotation component which is connected to a first rotating electric machine, and a third rotation component which is connected to a second rotating electric machine and the drive wheel, and wherein the regulation device switches between a state where a differential operation of the differential mechanism is regulated and a state where the differential operation of the differential mechanism is allowed.
