Title:
CONTROL DEVICE FOR VEHICLE DRIVE TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/104800
Kind Code:
A1
Abstract:
It is desirable that a control device be able to appropriately control the engagement pressure of an engagement-side engagement device, and the input torque transmitted from a drive power source to a transmission, thereby minimizing fluctuations in output torque during shifting. In the present invention, when, during shifting, changing the share of torque transmission between the engagement-side engagement device and the disengagement-side engagement device by controlling the engagement pressure of the engagement devices, an engagement-side control unit (46) performs specific engagement pressure control to change the engagement pressure of the engagement-side engagement device at either a constant rate of change, or a rate of change which is greater than said constant rate of change at the beginning of the change.
