  • Method for ascertaining an adhesion condition of a friction clutch
    Patent number: 9109990
    Abstract: A method for ascertaining an adhesion condition of a friction clutch operated with specified slip between an input part and an output part. In the case of rotational speed differences in the range of noise in the latter, a mean value and its variance are continuously derived from measurements taken by an unfiltered rotational speed difference between the input part and the output part, and when the mean value falls below a specified threshold and simultaneously the variance exceeds the mean value, the adhesion condition is recognized.
    Type: Grant
    Filed: April 16, 2013
    Date of Patent: August 18, 2015
    Assignee: Schaeffler Technologies AG & Co. KG
    Inventor: Rainer Praus

  • Method and device for controlling the slip of a vehicle clutch
    Patent number: 7813858
    Abstract: A method for controlling the slip of a vehicle clutch, wherein in the method the difference between a speed signal of the drive-end input shaft of the clutch and a filtered speed signal of a transmission-end clutch output shaft are maintained at a desired value.
