1. An apparatus for controlling a CVT mounted on a vehicle and transmitting power of a prime mover to a driven wheel through a belt wound around a drive pulley and a driven pulley that are supplied with hydraulic clamping pressure from a hydraulic mechanism to clamp the belt from lateral sides, an ABS mechanism adapted to reduce braking force to be applied to the driven wheel and an ABS controller for controlling operation of the ABS mechanism when the driven wheel is detected to be locked, comprising:

  • a pulley clamping pressure setting unit that sets the hydraulic clamping pressure of the pulleys based on torque to be transmitted by the belt;

    an ABS operation delay determiner that determines whether the operation of the ABS mechanism is delayed by the ABS controller; and

    a clamping pressure corrector that corrects the set hydraulic clamping pressure of the pulleys in accordance with a determination result of the ABS operation delay determiner.
