Title:
車両の変速制御装置
Document Type and Number:
Japanese Patent JP6845043
Kind Code:
B2
Abstract:
A shift control device of a vehicle including an internal combustion engine and a multi-speed transmission in series, the shift control device comprises: a control portion providing a downshift control in which an input shaft rotation speed of the multi-speed transmission is increased through a torque-up of the internal combustion engine toward a post-shift input shaft rotation speed in a neutral state where a release-side engagement device to be released during a downshift of the multi-speed transmission is released, so as to engage an engagement-side engagement device to be engaged after the shift. In the case of a shift pattern having a large internal inertia of the multi-speed transmission, the control portion controls a torque capacity of the engagement-side engagement device to a value greater than zero before starting a torque-up control of the internal combustion engine.
