Abstract
In a method for assessing a closed state of a clutch in a drive train of a motor vehicle, with which clutch a driver controls a frictional connection between an internal combustion engine and a change speed transmission of the motor vehicle, the assessment is carried out in dependence on a signal of a sensor which detects activation of the clutch. The method is distinguished by the fact that a difference in rotational speed which occurs across the clutch is determined and the assessment is additionally carried out in dependence on the difference in rotational speed. In addition, a control unit is configured to carry out the method.
