PROBLEM TO BE SOLVED: To set a lock-up capacity during coast traveling in a lock-up mode to quickly release a lock-up clutch during abruptly braking a vehicle while preventing the disengagement of the clutch. SOLUTION: When coast traveling is achieved during fastening the lock-up clutch, a lock-up capacity is reduced so that a slip rotating speed is a predetermined low rotating speed (S10). The lock-up capacity with the slip rotating speed being the predetermined low rotating speed is set as a learning value (S21). During a time after the slip rotating speed is the predetermined low rotating speed and before a predetermined time passes, deviation between the predetermined low rotating speed and an actual slip rotating speed is integrated (S24). The learning value is corrected in accordance with an integrated value for the deviation (S28). A minimum lock-up capacity is set to be the corrected learning value (S29).
