CONTINUOUSLY VARIABLE TRANSMISSION AND HYDRAULIC PRESSURE CONTROL METHOD THEREFOR

Title:

CONTINUOUSLY VARIABLE TRANSMISSION AND HYDRAULIC PRESSURE CONTROL METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2013/145967

Kind Code:

A1

Abstract:

In the present invention, on the basis of a transmission gear ratio, a target primary pressure and a target secondary pressure are set. At least, in a crosspoint region that is a region in which an absolute value of a deviation obtained by subtracting the target primary pressure from the target secondary pressure becomes smaller than a prescribed deviation, a target line pressure that is the target value of a line pressure is set to be a value in which an offset amount that is a positive value is added to the greater from between the target primary pressure and the target secondary pressure. The primary pressure, secondary pressure and line pressure are controlled to be the target primary pressure, target secondary pressure and target line pressure respectively.
