Problems solved by technology

[0004] However, as in Patent Document 1, if the specific engagement device is maintained in the direct-connected engaged state, the internal combustion engine and the rotating electrical machine rotate integrally, and the moment of inertia of the rotating member rotating integrally with the rotating electrical machine increases.
Therefore, there is a limit to shortening the period during which the rotation speed difference of the engagement device on the engagement side of the transmission is reduced by reducing the rotation speed of the rotary electric machine during the upshift control.

Abstract

The present invention relates to a control device for a vehicle drive device capable of shortening a period during which the rotational speed of a rotating electric machine is reduced to reduce a rotational speed difference of an engagement-side engagement device of a transmission during upshift control. The control device of this vehicle drive device controls the specific engagement device (SSC) to be in the slip engagement state when the rotation speed difference (ΔW1) of the engagement-side engagement device is reduced during the execution of the upshift control, and makes the rotary electric machine The rotational speed of (MG) is reduced relative to the rotational speed of the internal combustion engine (ENG).

Description

technical field [0001] The present invention relates to a control device for a vehicle drive device provided with a specific engagement device, a rotary electric machine, and a transmission device in this order from the internal combustion engine side in a power transmission path connecting an internal combustion engine and wheels. Background technique [0002] As for the above-mentioned control device, for example, a technique described in the following Patent Document 1 is known. In the technology described in Patent Document 1, upshift control (called upshift control) is performed from a state in which torque in the forward acceleration direction is being transmitted to the wheels until the specific engagement device is maintained in the directly connected engagement state. ). [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 9-331602 [0004] However, as in Patent Document 1, when the specific engagement device is maintained in the directly connecte...
