Abstract
Official abstract text for this publication.
A control device of a vehicle drive device includes a hydraulic power transmission device having an input-side rotating element to which power from an engine is input and an output-side rotating element outputting power to drive wheels, a first electric motor coupled to the input-side rotating element, and a second electric motor coupled to the drive wheels, the vehicle drive device having an electric path through which power is electrically transmitted between the first electric motor and the second electric motor and a mechanical path through which power is mechanically transmitted via the hydraulic power transmission device, the control device controlling an operating point of the engine by adjusting a torque of the first electric motor, the control device changing a proportion of power transmitted through the electric path and power transmission through the mechanical path based on a request amount when the operating point of the engine is controlled.
