Abstract
A vehicle driving apparatus includes: an engine; a first rotary electric machine; first and second output shafts; a power distribution device for distributing a power between the first and second output shafts; and a control device for controlling an electric-power generation torque of a second rotary electric machine such that a power distribution ratio between the first and second output shafts becomes a target distribution ratio, and controlling a total torque of the engine and the first rotary electric machine such that a requested drive torque is obtained. The control device executes an electric-power consuming control to supply at least a part of a generated electric power generated by the second rotary electric machine, to the first rotary electric machine without via a power storage device, and to drive the first rotary electric machine, such that an operation state of the engine is brought close to a fuel-economy optimum state.
