Abstract (en)

[origin: WO2019057495A1] The invention relates to a method for operating a drive train (10) of a motor vehicle having at least one centrifugal pendulum (12), wherein the centrifugal pendulum (12) has at least one primary part (16) that can rotate about an axis of rotation (14), at least one secondary part (18) that can move relative to the primary part (16) and at least one damping medium (20) via which relative movements between the primary part (16) and the secondary part (18) are hydraulically damped, wherein at least one temperature of the damping medium (20) is calculated by means of an electronic computing device (34) of the drive train (10) based on a calculation model.
