Document Type and Number:
WIPO Patent Application WO/2018/124219
Kind Code:
A1
Abstract:
The present invention addresses the problem of reducing response delay. An automatic transmission control device 10 is provided with: a sleeve 14 that is moved and operated by an actuator 18 and that performs engagement operation; an engine 11 connected to an input shaft 12; and a control unit 21 that controls movement of the sleeve 14 by the actuator 18 in addition to controlling rotation of the input shaft 12 by the engine 11 or by a motor generator 13. The control unit 21 executes synchronization control for controlling rotation of the input shaft 12 so that it is possible to engage with another gear after disengagement and, at least prior to the completion of synchronization, starts the execution of shift control in which the sleeve 14 is moved by the actuator 18 to an engagement completion position.
