ABSTRACT:
An apparatus and method for controlling a CVT (continuously variable transmission), and a program for executing the control method that reduces a transmission shock during a braking operation. When a foot brake switch is turned on and a vehicle speed is less than or equal to a threshold speed, the ECU increases a clamping pressure applied to a transmission belt to a pressure level higher than a normal pressure. When the vehicle speed falls to or below the threshold speed when the foot brake switch is turned on, the ECU prohibits an increase in the clamping pressure applied to the transmission belt.
