Method and device for stabilizing a semi-trailer

A method for stabilizing a vehicle combination of a trailer or semi-trailer and a towing vehicle having front wheels, said method comprising:

• determining and evaluating at least one dynamic movement input variable;
• if a rolling movement of the vehicle combination is detected by means of the evaluation, implementing at least braking interventions for stabilizing the dynamic movement state of the vehicle combination for the towing vehicle;
• and
• producing a yaw moment which counteracts the rolling movement of the vehicle combination, by means of braking interventions which are applied to the front wheels of the towing vehicle;
• wherein,
• braking interventions are implemented at the rear wheels of the towing vehicle;
• only when a predefined operating state of the vehicle combination is present;
• and
• the braking interventions which are implemented at the rear wheels effect an essentially constant braking at the rear wheels..

A device for stabilizing a vehicle combination comprising a trailer and a towing vehicle that has front wheels and rear wheels, said device comprising:

• means for determining and evaluating at least one dynamic movement input variable;
• means for implementing at least braking interventions at the front wheels of the towing vehicle, for stabilizing the dynamic movement state of the vehicle combination if a rolling movement of the vehicle combination is detected by means of the evaluation;
• wherein,
• a yaw moment which counteracts the rolling movement of the vehicle combination is produced by means of the braking interventions at the front wheels of the towing vehicle;
• braking interventions for the rear wheels of the towing vehicle are additionally permitted only when a predefined operating state of the vehicle combination is present;
• and
• the braking interventions which are additionally permitted or brought about for the rear wheels effect an essentially constant braking effect at the rear wheels.
