Abstract

An apparatus for stabilizing a vehicle combination made up of a tractor vehicle and a trailer or semitrailer. For this purpose, the apparatus contains a first determination arrangement used to determine an inflection angle variable that describes the angle between the longitudinal axis of the tractor vehicle and the longitudinal axis of the trailer or semitrailer. The apparatus also contains a processing arrangement with which a comparison is performed as a function of the inflection angle variable and a comparison variable. The apparatus contains a first actuator arrangement associated with the trailer or semitrailer and with which a brake pressure can be established at at least one wheel of the trailer or semitrailer. The first actuator arrangement is actuated at least as a function of the comparison performed with the processing arrangement. The apparatus furthermore contains a second determination arrangement with which the comparison variable is determined as a function of the velocity of the tractor vehicle and/or as a function of whether stability interventions are being performed for the tractor vehicle.
