The controller (21) is provided with: a lock-up capacity-controlling means for controlling the lock-up capacity (TLU) to a specified target capacity (TLU*) (TLU1) when the vehicle shifts to coasting; a timing means for measuring the time (Ts) that the slippage DeltaN, which is the difference between the rotation speed of the input element (engine rotation speed (Ne)) and the rotation speed of the output element (turbine rotation speed (Nt)), is within a specified range (∣DeltaN∣<N1) when the lock-up capacity (TLU) is controlled to the target capacity (TLU*) (TLU1); and a capacity-learning means for learned calibration of the target capacity (TLU*) (TLU1) so that the time (Ts) measured by the timing means is a specified target time (T*). The lock-up capacity can be accurately controlled by the learned calibration when the vehicle shifts to coasting. |
