Title:
CONTROL DEVICE FOR AUTOMATIC TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2020/013158
Kind Code:
A1
Abstract:
This control device for an automatic transmission has a feedback control unit (103) that calculates a target transmission gear ratio of a continuously variable transmission (CVT) on the basis of a travel state, and uses an integral compensator (301) to carry out feedback control on the basis of the deviation between the target transmission gear ratio and the actual transmission gear ratio of the continuously variable transmission (CVT). The feedback control unit stops the operation of the integral compensator (301) when the occurrence of a transient disturbance is estimated, and subsequently, when it is determined that the deviation does not fluctuate any more, the feedback control unit restarts the operation of the integral compensator (301).
