Abstract
A control apparatus includes a differential speed acquisition unit that acquires a differential speed representing a difference in speed between an input side drivingly connected to the input member of the fluid coupling and an output side drivingly connected to the transmission; a state determination unit that determines a shift speed in the transmission and an operating state of the direct connection clutch based on an accelerator opening and a vehicle speed of a vehicle; and a direct connection control unit that engages, if the differential speed is equal to or less than a predetermined engagement permitting threshold value when the state determination unit determines an upshift of the shift speed and a transition from a disengaged state to an engaged state of the direct connection clutch in a condition in which the accelerator opening is decreasing, the direct connection clutch regardless of an upshift operation of the shift speed.
