Abstract:
A vehicle driving apparatus includes: an engine; first and second rotary electric machines; a fluid transmission device including an input-side rotary element to which the engine and the first rotary electric machine are connected; and a control device configured to control an operation point of the engine by adjusting an electrical path amount in an electrical path between the first and second rotary electric machines. When a certain running mode is established, the control device is configured to correct the electrical path amount to an increased electrical path amount while maintaining an power of the engine requested by an operation of a vehicle driver, and to drive the second rotary electric machine, while controlling an output torque of the first rotary electric machine such that the electrical path amount transferred from the first rotary electric machine to the second rotary electric machine becomes the increased electrical path amount.
