摘要： PROBLEM TO BE SOLVED: To enable learning of a command value for making a lock-up clutch a state immediately before engagement, in a less disturbance state.SOLUTION: When a shift range is set at an N range or a transmission is in a neutral state by a neutral control, a command value for controlling a pressure difference of the lock-up clutch rises in stages (ST5, ST6, and ST10). Furthermore, the command value when the lock-up clutch moves from a release state to a slip state is detected based on a change of a slip amount of a torque convertor for the rising command value. Accordingly, on the basis of the command value, the command value for making the lock-up clutch the state immediately before engagement is learnt (ST7).

摘要： PROBLEM TO BE SOLVED: To accurately perform switching of control between open control and feedback control during lockup slip control. SOLUTION: Start-up lockup slip control is switched between open control and feedback control according to the torque capacity change rate T C ' of a lockup clutch 26. Therefore, even if various errors cause a slippage of an absolute value of torque capacity T C of the lockup clutch 26 to a normal torque capacity T C calculated without error, a torque capacity change rate T C ' containing error is made to substantially the same value as a normal torque capacity change rate T C '. Consequently, the switching of control between open control and feedback control during start-up lockup slip control can be accurately performed regardless of an error such that it affects the absolute value of torque capacity T C .
