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

A need exists for a control device that would allow the rotational speed of a rotating electric motor to be reduced and the period of a lower rotational speed difference for the engagement-side engaging device of a transmission to be shortened during on-upshift control. A control apparatus for a vehicle drive apparatus wherein a specific engagement device (SSC) is controlled to be in a state of sliding engagement, and the rotational speed of a rotating electric motor (MG) is reduced relative to the rotational speed of an internal combustion engine (ENG) when the rotational speed difference (DELTA W1) of the engagement-side engaging device is reduced during on-upshift control.

Description

technical field [0001] The present invention relates to a control device for a vehicle drive device which includes a specific engagement device, a rotary electric machine, and a transmission device in order from the internal combustion engine side on a power transmission path connecting an internal combustion engine and wheels. Background technique [0002] Regarding such a control device as described above, for example, a technique described in Patent Document 1 below is known. In the technique described in Patent Document 1, the upshift control (referred to as upshift control) is performed from the state in which the torque in the forward acceleration direction is being transmitted to the wheels until the specific engagement device is maintained in the directly coupled engagement state. ). [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 9-331602 [0004] However, as in Patent Document 1, if the specific engagement device is maintained in the directl...
