To provide a control device for a vehicular lockup clutch capable of sufficiently securing the responsiveness of the lockup clutch in a flexible start control.

The flexible start control for slip-engaging the lockup clutch 32 is performed when a vehicle starts moving, and before starting the flexible start control, a precharge control for establishing a standby state in which a predetermined preparation pressure is indicated to a linear solenoid valve SLU for slip control is performed. Since output oil pressure PSLU output from the linear solenoid valve SLU is increased to about the preparation pressure just before starting the flexible start control, the responsiveness of the lockup clutch 32 in the flexible start control can be sufficiently secured. Thus, the racing of an engine 28 or the like which results from response delay of hydraulic control in the flexible start control can be appropriately suppressed to improve the fuel efficiency.
