Abstract

A shift control device (70) of a vehicle (10) including an internal combustion engine (12) and a multi-speed transmission (22) in series, the shift control device comprising: a control portion (72, 74) providing a downshift control in which an input shaft rotation speed of the multi-speed transmission is increased through a torque-up control of the internal combustion engine (12) toward a post-shift input shaft rotation speed in a neutral state where a release-side frictional engagement device to be released during a downshift of the multi-speed transmission (22) is released, so as to engage an engagement-side frictional engagement device to be engaged after the shift; and a torque setting portion setting a required torque of the internal combustion engine (12) in the torque-up control of the internal combustion engine (12) such that an increasing rate of an actual torque of the internal combustion engine becomes smaller in the case of a shift pattern having a large internal inertia of the multi-speed transmission during the downshift as compared to the case of a shift pattern in which the internal inertia is small.
