Abstract
A method for determining a slip value describing the reliability of torque transmission between two conical disk pairs of a continuously variable transmission. The conical disk pairs are frictionally engaged by an endless torque-transmitting component. The contact pressure between at least one conical disk pair and the endless torque-transmitting component is modulated, and the slip value is determined from the difference in rotational speeds of the conical disk pairs upon modulation of the contact pressure. The pressure modulation is carried out at a modulation frequency that is above the transmission ratio adjustment frequency of the transmission and at a predetermined amplitude.
