When a line pressure PL serving as a source pressure of a primary pulley (2) and a secondary pulley (3) is controlled on the basis of a control deviation DeltaStep, which is the deviation between a step count StepMdl of a step motor (27) corresponding to a target speed ratio I (o) and a value obtained by adding a target deviation GTstep and a starting learned value Gstep to a step count Bstep of the step motor (27) corresponding to an actual speed ratio ip, the engine torque varies dramatically beyond the range of a predetermined value T1 and a predetermined value T2 during a predetermined time period t1, a learning error determination relating to the starting learned value Gstep is prohibited for a predetermined time period t2.
