Title: METHOD FOR DETECTING A PERFORMED SELF-ADJUSTMENT OF AN AUTOMATED INACTIVATED CLOSED CLUTCH OF A VEHICLE, PREFERABLY A HYBRID SEPARATING CLUTCH OF A HYBRID VEHICLE
Abstract:
The invention relates to a method for detecting a performed self-adjustment of an automated inactivated closed clutch of a vehicle, preferably a hybrid separating clutch of a hybrid vehicle, wherein an adjustment of an adjusting device of the clutch is checked by means of an adjustment of a pre-load point of the clutch, wherein a clutch characteristic curve is adapted when the position of the pre-load point has changed. In a method, in which the vehicle remains operational despite the detection of the performed self-adjustment, the adjustment of the pre-load point is detected and a deviation of the detected pre-load point with respect to a predetermined pre-load point is determined and stored. Subsequently, a bite point of the clutch characteristic curve is adapted, wherein the bite point is compared with a bite point boundary region that varies as a function of the detected pre-load point and, on the basis of said comparison, a further use of the bite point is checked.
