Abstract
A vehicle drive device having an input member coupled to an internal combustion engine; an output member coupled to a wheel; a first rotating electrical machine; a second rotating electrical machine; and a differential gear unit having at least three rotating elements. A dog engagement device is provided on a power transmission path between the input member and an input rotating element. The engagement device includes a state selecting member that switches a state among three states, which are a first state where the input rotating element and the input member are coupled and the input rotating element and a non-rotating member are not coupled, a second state where the input rotating element coupled with both the input member and the non-rotating member, and a third state where the input rotating element and the non-rotating member are coupled.
