Abstract
A control device of a vehicle including a multi-speed transmission having plurality of gear positions different in gear ratio selectively established by controlling engagement and release predetermined engagement devices out of plurality engagement devices, the control device involves: shift control portion configured to provide delay control of delaying time point starting provision of release-side torque phase control reducing a torque capacity of release-side engagement device by a preset delay time with respect to time point of starting provision of a torque phase control of generating a torque capacity of an engagement-side engagement device during a torque phase in a drive upshift; and a delay time setting portion configured to preset the delay time such that the delay time is shortened when a shared torque of the release-side engagement device before start of the torque phase in the drive upshift is high, as compared to when the shared torque is low.
