摘要： 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.

摘要： A control system controls a line pressure applied to a CVT upon taking account of a certrifugal pressure caused by a rotation of pulleys. The control system determines whether the centrifugal pressure is greater than a predeterminied value only by which the pulley transmits an input torque from an engine. When the determination is affirmative, a lower limit of a duty ratio for operating a line pressure control valve is switched from a lower limit of a linear range to 0% duty ratio. Therefore, an actual transmissiou ratio control range is expanded while preventing an undershoot of the line pressure.

摘要： A control system for a continuously variable transmission having a drive pulley with a hydraulically shiftable disc and a hydraulic cylinder for operating the disc, a driven pulley with a hydraulically shiftable disc and a hydraulic cylinder, and a pressure regulator valve for regulating pressure of oil supplied to the hydraulic cylinders. The pressure regulator valve has a pressure level changing port to increase the pressure of oil supplied to the cylinders. A solenoid operated valve is provided for supplying the oil to the pressure level changing port or for draining the port. When wheels of a vehicle spin, the solenoid operated valve is energized to supply the oil to the port, thereby increasing the pressure of the oil.
