Claim:
1. A hybrid vehicle driving apparatus comprising: an engine; a first rotating machine; a second rotating machine; a plurality of planetary gear mechanisms capable of forming a four-element complex planetary mechanism including four input/output elements to which the engine, the first rotating machine, the second rotating machine, and drive wheels are connected; and a controller configured to control the first rotating machine and the second rotating machine, wherein in a collinear diagram representing directions of rotation of respective planetary gear mechanisms within the four-element complex planetary mechanism, the first rotating machine and the second rotating machine are adjacent to each other and disposed on one side with respect to the engine, and in a state in which the four-element complex planetary mechanism is formed, the controller is configured to operate, in a predetermined mode, the first rotating machine and the second rotating machine at operating points at which a total of absolute values of workloads of the first rotating machine and the second rotating machine is smaller than the total of the absolute values at operating points providing an electric power balance between the first rotating machine and the second rotating machine represented by the following equation (1): where Tmg1 is a target torque of the first rotating machine, Nmg1 is a target rotational speed of the first rotating machine, Tmg2 is a target torque of the second rotating machine, and Nmg2 is a target rotational speed of the second rotating machine.
