To properly carry out speed-change control even when the input torque changes after starting speed-change control in a speed-change controller carrying out learning correction of a command value related to engaging force of a friction engagement device such that predetermined speed-change operation is carried out.

If a change of the input torque TIN during speed-change control satisfies a predetermined criterion (a time t1), a release side oil pressure command value SPB2 is set as 0 to forcibly release a second brake B2, and a set value of a forced termination timer is increased. Speed-change is thereby promptly carried out, speed-change delay caused by release delay of the second brake B2 is suppressed, an engagement side first brake B1 is properly engaged and speed-change control is terminated before the forced termination timer reaches the set value (a time t3), and transmission shock due to forced termination is prevented.
