A method for controlling a clutch unit for a drive train of a motor vehicle, wherein the clutch unit comprises a wet-running friction clutch for controllably transmitting torque from an input element to an output element of the clutch unit, wherein the clutch unit comprises oil for cooling the friction clutch, wherein heat inputs which contribute to heating the oil of the clutch unit are calculated, heat outflows which contribute to cooling the oil of the clutch unit are calculated and, as a function of the heat inputs and heat outflows, a maximum admissible clutch torque is calculated, and wherein the current clutch torque of the friction clutch is limited to the maximum admissible clutch torque.

Method for controlling a clutch unit

A transmission arrangement () for the controllable distribution of drive torque from an input element () to at least one output element (), comprising a first transmission part region (), namely a planetary gear mechanism, and an additional drive unit (), the first transmission part region () being drive-connected directly or indirectly to the input element () and to the additional drive unit (), and the first transmission part region () being drive-connected directly or indirectly to the output element ().
