Utility
Control Device
7 Sep 23
When a control device allows a shift speed formed by a transmission to transition from a pre-shift shift speed to a post-shift shift speed by performing engagement of an engagement-side engagement device and disengagement of a disengagement-side engagement device, the control device allows a torque phase in which a torque-sharing ratio between the engagement-side engagement device and the disengagement-side engagement device changes to proceed by performing engagement control in which transmission torque of the engagement-side engagement device is allowed to gradually increase.
