| Zusammenfassung: | The disclosure of Japanese Patent Application No. 2000-151301 filed on May 23, 2000, including the specification, drawings and abstract, is incorporated herein by reference in its entirety.
A method and apparatus for controlling a continuously variable transmission of a motor vehicle includes a controller that controls the speed ratio of the continuously variable transmission in accordance with a predetermined shift condition. The method and apparatus perform shift control in a specific manner during an operation of an anti-lock brake system, for example, by smoothing at least one of the rotational speed of the input shaft and the rotational speed of the output shaft, reducing a rate of change in the speed ratio during down shifting, restricting upshifting of the CVT, increasing an amount of hydraulic oil delivered from an oil pump, and/or increasing belt clamping force. |
