Abstract
Description
Die Erfindung betrifft ein Lenksystem eines Fahrzeugs, insbesondere Kraftfahrzeugs, mit einer Überlagerungsvorrichtung.The The invention relates to a steering system of a vehicle, in particular Motor vehicle, with a superposition device.
Aus
der
Ausgehend hiervon soll eine einfache Möglichkeit zur Realisierung eines solchen Lenksystems geschaffen werden.outgoing this is an easy way be created for the realization of such a steering system.
Diese Aufgabe wird durch ein Lenksystem mit den Merkmalen des Patentanspruches 1 gelöst.These Task is by a steering system with the features of claim 1 solved.
Das erfindungsgemäße Lenksystem weist eine Überlagerungsvorrichtung mit einer ansteuerbaren Stelleinrichtung auf, die über ein Antriebsteil mit einem ersten Getriebeeingang eines Überlagerungsgetriebes verbunden ist. Zur Verbindung eines Lenkrads des Lenksystems mit einem zweiten Getriebeeingang des Überlagerungsgetriebes ist eine Lenkradwelle vorgesehenen und zur Verbindung eines Getriebeausgangs des Überlagerungsgetriebes mit einem Lenkgetriebe des Lenksystems dient eine Ausgangswelle. Eine Verriegelungseinrichtung stellt in ihrem Verriegelungszustand die Drehbewegungsübertragung zwischen dem zweiten Getriebeeingang und dem Getriebeausgang sicher und lässt in ihrem Freigabezustand die Drehbewegungen an den Getriebeeingängen und am Getriebeausgang unbeeinflusst. Ein Fahrberechtigungssystem prüft die Fahrberechtigung des Fahrers und löst das Umschalten der Verriegelungseinrichtung in ihren Freigabezustand aus, wenn das Fahrberechtigungssystem einen nichtberechtigten Fahrer festgestellt hat. Das Umschalten der Verriegelungseinrichtung in den Freigabezustand im Falle eines nichtberechtigten Fahrers gewährleistet, dass keine Zwangskopplung zwischen dem zweiten Getriebeeingang und dem Getriebeausgang besteht, so dass die Lenkbarkeit des Fahrzeugs durch die Verriegelungseinrichtung nicht sichergestellt ist. Durch diese Maßnahme kann die Lenkbarkeit des Fahrzeugs aufgehoben werden, so dass das Fahrzeug gegen das Fahren durch einen Nichtberechtigten gesichert werden kann. Das Lenksystem mit Überlagerungsvorrichtung ermöglicht eine sehr einfache Realisierung eines Diebstahlschutzes.The steering system according to the invention has an overlay device with a controllable adjusting device, which via a Drive part with a first transmission input of a superposition gear connected is. To connect a steering wheel of the steering system with a second transmission input of the superposition gear is a steering wheel shaft provided and for connecting a transmission output of the superposition gearing with a steering gear of the steering system is an output shaft. A locking device is in its locked state the rotary motion transmission between the second transmission input and the transmission output safely and lets in their release state, the rotational movements at the transmission inputs and at the transmission output unaffected. A driving authorization system checks the driving authorization of the driver and releases the switching of the locking device in its release state if the driver authorization system is an unauthorized driver Has been established. Switching the locking device in ensures the release status in the case of an unauthorized driver, that no forced coupling between the second transmission input and the transmission output is made, allowing the steerability of the vehicle is not ensured by the locking device. By This measure the steerability of the vehicle can be lifted, so that the Vehicle secured against driving by an unauthorized person can be. The steering system with overlay device allows one very simple realization of a theft protection.
Vorteilhafte Ausgestaltungen des Lenksystems ergeben sich aus den abhängigen Patentansprüchen.advantageous Embodiments of the steering system will become apparent from the dependent claims.
Vorteilhafterweise bleibt die Stelleinrichtung dann unbetätigt, wenn das Überlagerungsgetriebe in der Übertragungsverbindung vom zweiten Getriebeeingang zum Getriebeausgang nicht-selbsthemmend ausgeführt ist und wenn das Fahrberechtigungssystem einen nichtberechtigten Fahrer festgestellt hat. Das Umschalten der Verriegelungseinrichtung in ihren Freigabezustand reicht aus, um die Lenkbarkeit des Fahrzeugs über das Lenkrad aufzuheben und das Fahrzeug dadurch gegen das unberechtigte Fahren zu sichern. Eine Drehung des Lenkrades bewirkt bei dieser Ausgestaltung keine Drehbewegung am Getriebeausgang.advantageously, the actuator then remains unconfirmed when the superposition gearing in the transmission connection from the second transmission input to the transmission output is non-self-locking executed and if the driving authorization system is an unauthorized driver Has been established. Switching the locking device in their release state is sufficient to the steerability of the vehicle over the Lift the steering wheel and thereby the vehicle against the unauthorized To secure driving. A rotation of the steering wheel causes this Design no rotational movement at the transmission output.
Alternativ hierzu kann es vorgesehen sein, dass dann, wenn das Überlagerungsgetriebe in der Übertragungsverbindung vom zweiten Getriebeeingang zum Getriebeausgang selbsthemmend ausgeführt ist und wenn das Fahrberechtigungssystem einen nichtberechtigten Fahrer festgestellt hat, die Stelleinrichtung die Drehstellung der Ausgangswelle entsprechend einem vorgebbaren Lenkwinkel an den lenkbaren Fahrzeugrädern einstellt, wobei diese Drehstellung unabhängig ist von der Drehstellung der Lenkradwelle. Zusätzlich zum Umschalten der Verriegelungseinrichtung in ihren Freigabezustand wird die Stelleinrichtung derart unabhängig von der Drehstellung der Lenkradwelle bzw. des Lenkrades angesteuert, dass der sich an den lenkbaren Fahrzeugrädern einstellende Lenkwinkel nicht der Lenkradstellung entspricht. Beispielsweise kann einfach der aktuelle Lenkwinkel unverändert bleiben unabhängig davon, welche Drehbewegung am Lenkrad ausgeführt wird. Dazu wird die Stelleinrichtung gegensinnig zur Lenkraddrehung betrieben, so dass sich die Drehbewegungen an den beiden Getriebeeingängen gegenseitig aufheben.alternative For this purpose, it may be provided that, when the superposition gear in the transmission connection From the second transmission input to the transmission output is designed self-locking and if the driving authorization system is an unauthorized driver has determined, the adjusting device according to the rotational position of the output shaft sets a predefinable steering angle on the steerable vehicle wheels, this rotational position is independent is from the rotational position of the steering wheel shaft. In addition to switching the locking device in its release state, the actuator is so independent of the rotational position of the steering wheel shaft or the steering wheel is controlled, that is the steering angle adjusting to the steerable vehicle wheels does not correspond to the steering wheel position. For example, easy the current steering angle unchanged stay independent of which rotational movement is carried out on the steering wheel. For this purpose, the adjusting device operated in the opposite direction to the steering wheel rotation, so that the rotational movements at the two transmission inputs each other cancel.
