Abstract (en)

[origin: WO2006063547A1] In order to determine a slip variable describing the reliability of torque transmission between two conical disk pairs of a conical disk continuously variable gearbox, which are frictionally engaged by a wrap-around means, the pressure between at least one conical disk pair and the wrap-around means is modulated and the slip variable is determined from the difference in rotational speed of the conical disk pairs upon modulation of the pressure, wherein said pressure modulation is carried out with a frequency, that is above the adjustment frequency of the transmission ratio of the gearbox, and a predetermined amplitude.
