Aus der DE 197 42 702 C2 ist eine Einrichtung zum Dämpfen von Schlingerbewegungen für mind. ein von einem Zugfahrzeug gezogenes Anhängersegment bekannt, bei dem die Winkelgeschwindigkeit des Anhängersegmentes um den Momentanpol oder der Knickwinkel um den Momentanpol erfasst und differenziert wird, und zur Regelung der Radbremsen des Anhängers heran gezogen wird. Als Sensoren für die Winkelgeschwindigkeit dienen Beschleunigungsmesser in unterschiedlicher Lage. DE 197 42 702 C2 describes a device for steaming of rolling movements for at least one of a towing vehicle trailer segment known, in which the Angular speed of the trailer segment around the instantaneous pole or the kink angle around the current pole is recorded and differentiated and to regulate the wheel brakes of the trailer is pulled. As sensors for the angular velocity serve accelerometers in different positions.

The invention has for its object a device to stabilize a trailer to create the is inexpensive and an increase in driving speed Towing vehicle with trailer attached.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass eine Einrichtung zum Stabilisieren eines Anhängers mit einer Bremsbetätigungsvorrichtung vorgesehen ist, die über mind. ein Bremsseil auf eine Radbremse einwirkt und für die Betätigung des Bremsseils ein Elektromotor vorgesehen ist, der von einer Fahrdynamikregelung derart betätigbar ist, dass in Abhängigkeit von sensorisch erfaßten Instabilitäten des Anhängers der Anhänger über eine Betätigung der Radbremse stabilisiert wird. According to the invention, this object is achieved in that a Device for stabilizing a trailer with a Brake actuation device is provided, which over min. a brake cable acts on a wheel brake and for that Actuation of the brake cable, an electric motor is provided can be actuated by a vehicle dynamics control system such that in Dependence on instabilities of the sensor Trailer of the trailer by operating the wheel brake is stabilized.
Dabei erfolgt über die von Sensoren erfaßten und in einer Fahrdynamikregelung logisch verknüpften und analysierten Messdaten, in die Daten eines Kraftfahrzeugs einbezogen werden können, eine Generierung eines Ansteuersignals für einen Elektromotor, der einen Aktuator verstellt und damit die Radbremse betätigt. Durch die Einbremsung eines Rades des Anhängers oder durch die Einbremsung beider Räder des Anhängers mit unterschiedlichem Bremsdruck werden durch Abbau der Seitenkräfte an dem einen Rad und Erhöhung der Längskräfte die sensorisch erfassten Instabilitäten des Anhängers korrigiert. Der Anhänger weist bevorzugt eine Achse mit zwei Rädern auf. This takes place via those detected by sensors and in one Vehicle dynamics control logically linked and analyzed Measurement data, included in the data of a motor vehicle can be a generation of a control signal for a Electric motor that adjusts an actuator and thus the Wheel brake applied. By braking a wheel of the Trailer or by braking both wheels of the Trailers with different brake pressure are reduced by the Lateral forces on one wheel and increased longitudinal forces the sensed instabilities of the trailer corrected. The trailer preferably has one axis with two Wheels on.

Die Trommelbremsen sind über eine verschiebbar geführte Anhängevorrichtung und über den Elektromotor unabhängig voneinander betätigbar. Durch die verschiebbar geführte Anhängevorrichtung wird der Anhänger vor dem Fahrzeug eingebremst. Nach einem weiteren Ausführungsbeispiel weist die Trommelbremse zwei Bremsbacken und ein Spreizelement auf. Mittels eines Kraftübertragungselementes, welches mit dem Elektromotor und dem Spreizelement verbunden ist, können die zwei Bremsbacken betätigt und nach Maßgabe der von der Fahrdynamikregelung ausgegebenen Ansteuersignale der Anhänger stabilisiert werden. The trailer advantageously has at least one, preferably two trained as drum brakes wheel brakes on a Brake cable can be actuated. The drum brakes are over one slidably guided hitch and over the Electric motor can be operated independently of one another. Through the the trailer is slidably guided braked the vehicle.

Eine weitere Einrichtung sieht vor, dass die Bremsbacken der Trommelbremse mittels einer linear verschiebbaren Spindel betätigbar sind. Die Spindel wird direkt von dem Elektromotor angetrieben und verschiebt diese linear beidseitig in Richtung der Bremsbacken. Die Bremsbacken werden über ein Zugelement in ihre Ausgangslage zurück geführt, wenn die Spreizelemente sich in ihrer Ausgangslage befinden bzw. das Bremsseil sich in seiner Ausgangslage befindet. Another device provides that the brake shoes of the Drum brake using a linearly displaceable spindle can be operated. The spindle is straight from that Electric motor driven and moved linearly on both sides in Direction of the brake shoes. The brake shoes are about one Traction element returned to its starting position when the Spreading elements are in their starting position or that Brake cable is in its starting position.
