Abstract

Provided is a control device of a vehicle capable of providing a tie-up control corresponding to a frictional load of an engagement-side engagement device during a torque phase in a drive upshift. In the presetting of a delay time tdel in a delay control of delaying the time point of starting the provision of a release-side torque phase control of reducing a release-side clutch torque with respect to the time point of starting the provision of a torque phase control of generating an engagement-side clutch torque during the torque phase in the drive upshift, the delay time tdel is shortened when a release-element shared torque before the start of the torque phase in the drive upshift is high, as compared to when the release-element shared torque is low, and therefore, the drive upshift can be performed with a tie-up corresponding to the frictional load of an engagement element changing in accordance with an input torque Ti that is the basis of the release-element shared torque before the start of the torque phase. Thus, the tie-up control corresponding to the frictional load of the engagement element can be provided during the torque phase in the drive upshift.
