Title:
CONTROL DEVICE FOR AUTOMATIC TRANSMISSION AND CONTROL METHOD FOR AUTOMATIC TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2019/159978
Kind Code:
A1
Abstract:
According to the present invention, an AT controller 10 has a continuous shift control processing unit 10a which executes a step-down continuous shift through a front shift and a rear shift during which the progresses of a shift change overlap each other, when there is a down-shift request for transitioning from a high-shift stage to a low-shift stage with an intermediate-shift stage skipped according to an accelerator stepping operation while traveling. The continuous shift control processing unit 10a corrects a rear shift release indication pressure for a rear shift release clutch so that the rear shift release clutch does not slip until the completion of the front shift and starts to slip after the completion of the front shift, when a front shift engaging capacity or a rear shift engaging capacity is generated during the progress of the front shift.
