Zusammenfassung:PROBLEM TO BE SOLVED: To perform an appropriate restriction against vibration or shock caused by a coupling of a lock-up clutch.SOLUTION: A complete coupling of a lock-up clutch is prevented by keeping an engine-speed higher than a rotational speed of a turbine of a torque converter until a vehicle speed exceeds a threshold value (in which neither a vibration nor a shock occurs along with a coupling of the lock-up clutch) after the engaging of the lock-up clutch of the torque converter is started.
