摘要：
A control apparatus for a continuously variable transmission includes a clamping force increase portion. The continuously variable transmission includes a pair of a primary pulley and a secondary pulley on which a transmission belt is wound. A shift of the continuously variable transmission is performed by changing effective diameters of the primary pulley and the secondary pulley. The clamping force increase portion increases a belt clamping force when it is determined that a torque capacity is decreased by determining that drive power input to the primary pulley is decreased by an amount equal to or larger than a predetermined amount while the secondary pulley is in a stopped state or a substantially stopped state, as compared to when it is determined that the torque capacity is not decreased.
