Abstract
A control apparatus includes an ECU that is configured to: start engagement transition control for outputting an engagement transitional hydraulic pressure command value that causes an engagement device to be actuated from a released state toward an engaged state from when an operating member is displaced from a non-drive operating position; when an engagement transition time is longer than a target time, learn the engagement transitional hydraulic pressure command value such that the engagement transitional hydraulic pressure command value increases; when the engagement transition time is shorter than the target time, learn the engagement transitional hydraulic pressure command value such that the engagement transitional hydraulic pressure command value reduces; and prohibit learning of the engagement transitional hydraulic pressure command value or invalidate the learned engagement transitional hydraulic pressure command value, when the operating time of the operating member is longer than a predetermined time.
