In a method of detecting the operating state of a friction clutch which may be engaged and disengaged axially, as a result of being triggered by an actuation, an engagement point is determined from the parameters clutch engagement travel and associated clutch torque and/or associated clutch rotational speed, and its associated engagement travel is stored. In a method step independent of the actuations, a permissible maximum value of the engagement travel is stored. In a method step triggered by an actuation, a comparison is performed in which the engagement travel of the engagement point is compared with the permissible maximum engagement travel. In a method step which necessarily follows the method step relating to the comparison, if the engagement travel of the engagement point is greater than the permissible maximum engagement travel, a signal is displayed in order to be able to perform repairs.

Method of detecting the operating state of a friction clutch

A self-supporting structure for a motor vehicle with at least one transverse connection is provided. At least one transverse connection for stiffening the body structure is provided which is made in one piece from a dimensionally stable light weight metal or plastic foam and extends over the entire width of the body structure.
