Abstract
A method for operating a drivetrain of a motor vehicle having at least one centrifugal pendulum, in which the centrifugal pendulum comprises at least one primary part rotatable about an axis of rotation, at least one secondary part movable relative to the primary part, and at least one damping medium by which relative movements are hydraulically dampened between the primary part and the secondary part, wherein at least one temperature of the damping medium is calculated by an electronic calculating device of the drivetrain with the aid of a mathematical model.

A method for operating a drivetrain of a motor vehicle comprising:
- at least one centrifugal pendulum, in which the centrifugal pendulum comprises at least one primary part rotatable about an axis of rotation, at least one secondary part movable relative to the primary part, and at least one damping medium by which relative movements are hydraulically dampened between the primary part and the secondary part, wherein at least one temperature of the damping medium is calculated by an electronic calculating device of the drivetrain with the aid of a mathematical model.
A drivetrain for a motor vehicle, having at least one centrifugal pendulum, which comprises at least one primary part rotatable about an axis of rotation, at least one secondary part movable relative to the primary part, and at least one damping medium by which relative movements are to be hydraulically dampened between the primary part and the secondary part,
- an electronic calculating device, which is adapted to calculate at least one temperature of the damping medium with the aid of a mathematical model.
