A target primary pressure and a target secondary pressure are set based on a speed ratio, a target line pressure as a target value of a line pressure is set to be a value obtained by adding an offset amount, as a positive value, to either one having a higher value out of the target primary pressure and the target secondary pressure, in at least a cross-point region as a region where an absolute value of a deviation, obtained by subtracting the target primary pressure from the target secondary pressure, is smaller than a predetermined deviation, and a primary pressure, a secondary pressure, and the line pressure are controlled to be the target primary pressure, the target secondary pressure, and the target line pressure, respectively.
