<p>When the revolving speed (Nout) of a secondary pulley (150) is less than a first reference amount (Nout1), the disclosed electronic control device (300) implements lower limit hydraulic pressure control (step S100) which adjusts the hydraulic pressure (Pin) of a primary pulley (130) to be at a lower limit hydraulic pressure (Pinlim). When the revolving speed (Nout) is equal to or exceeds the first reference amount (Nout1), but is less than a second reference amount (Nout2), the electronic control device (300) implements balanced hydraulic pressure control (step S200) which adjusts the hydraulic pressure (Pin) to be greater than the lower limit hydraulic pressure (Pinlim). When the revolving speed (Nout) is equal to or exceeds the second reference amount (Nout2), the electronic control device (300) implements feedback control (step S300) which corrects the hydraulic pressure (Pin) on the basis of the size of the difference between a target transmission ratio (?trg) and a transmission ratio (?), calculated on the basis of revolving speeds (Nin, Nout) detected by each revolving speed sensor (305, 306).</p> |
