Abstract
A method for controlling a continuously variable transmission is a control method of controlling in/out of oil to/from a primary oil chamber by using an oil pump provided in an oil passage between the primary oil chamber and a secondary oil chamber. The method includes: an abnormality determination step of determining whether rotation of the oil pump is abnormal; and when it is determined that the rotation is abnormal in the abnormality determination step, a hydraulic control step of making a secondary oil pressure higher than a pressure before the determination of abnormality.
