A controller 21 is provided with a lock-up capacity control means for controlling a lock-up capacity TLU to a predetermined target capacity TLU* (TLU1) when a transition to a coast running state occurs, a timing means for measuring a time Ts during which a slippage ”N, which is a difference between a revolution speed (engine speed Ne) of an input element and a revolution speed (turbine speed Nt) of an output element, is within a predetermined range (|”N|<N1) when the lock-up capacity TLU is controlled to the target capacity TLU* (TLU1), and a capacity learning means for making a learning-correction to the target capacity TLU* (TLU1) such that the time Ts measured by the timing means is brought to a predetermined target time T*. By virtue of the learning-correction, it is possible to accurately control the lock-up capacity when the transition to the coast running state has occurred. |
