Abstract

A method for operating a drive train of a vehicle having a clutch assembly, in particular for distributing torque to a primary axle and a secondary axle of the vehicle and/or for distributing torque between two wheels of one axle of the vehicle, comprises at least the following steps:a) determining temperature data at least from an electronic control unit which is assigned to the clutch assembly, or from an actuation unit of the clutch assembly;b) evaluating the temperature data determined in step a); andc) reducing an effective value of a control current at least of the electronic control unit or of the actuation unit by pulsing the control current if the evaluation in step b) reveals that a temperature at least of the electronic control unit or of the actuation unit exceeds a threshold value.
