Title:
CONTROL DEVICE FOR AUTOMATIC TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2017/159203
Kind Code:
A1
Abstract:
This control device for an automatic transmission comprises: a continuously variable transmission mechanism (CVT); a target transmission ratio calculation unit (101) that calculates a target transmission ratio on the basis of a traveling state; a feedback control unit (103) that provides feedback control on the basis of an actual value, said actual value expressing the state of the continuously variable transmission mechanism (CVT); a phase compensation unit (104) that performs phase lead compensation of the feedback control on the basis of the traveling state; and a phase compensation control unit (109) that, when an unstable traveling state of a vehicle is detected, halts the phase lead compensation performed by the phase lead compensation unit (104). The present invention thus allows changes in the behavior of a vehicle to be suppressed, and can suppress a feeling of discomfort for a driver.
