When deceleration lock-up differential pressure learning control is entered and a difference between this deceleration lock-up differential pressure instruction value and a disengagement initial pressure of lock-up smooth off control becomes smaller than prior to deceleration lock-up differential pressure learning control, the disengagement initial pressure PS of lock-up smooth off control is corrected to a low side in accordance with a difference between that deceleration lock-up differential pressure instruction value and the disengagement initial pressure. Furthermore, by changing the sweep gradient of lock-up smooth off control to a small side, and in addition, correcting the disengagement initial pressure PS of lock-up smooth off control to a low side in consideration of disengagement delay of the lock-up clutch pursuant to that sweep gradient change, the actual disengagement time during lock-up smooth off control can be matched with a target disengagement time.
