Ein X-By-Wire-System gemäß der vorliegenden Erfindung ist durch die in Patentanspruch 1 beschriebenen Merkmale gekennzeichnet.One X-by-wire system according to the present invention Invention is characterized by the features described in claim 1 characterized.
Es ist die Aufgabe der vorliegenden Erfindung, ein X-By-Wire-System für ein Kraftfahrzeug bereitzustellen, bei dem elektrisch bedienbare Bremsen auf vielfältige Weise betätigt werden können. Die vorliegende Erfindung kann auch ein System bereitstellen, bei dem alternative Steuerungsan ordnungen eingesetzt werden können, wenn eine oder mehrere Komponenten des Systems ausfallen.It The object of the present invention is an X-by-wire system for a To provide motor vehicle, in the electrically operated brakes on diverse Way pressed can be. The present invention can also provide a system in the alternative control arrangements can be used, if one or more components of the system fail.

Die vorliegende Erfindung stellt eine neue Topologie und Zusammensetzung zur Kommunikationsvernetzung, Signalteilung, Sicherheit und Aufintegration von physikalischen Einheiten bereit. Bei der ersten Ausführungsform besteht die Hauptkommunikation aus zwei unabhängigen Bussystemen, die mit unterschiedlichen Protokollen (in einem heterogenen Konzept) laufen. Bei der zweiten Ausführungsform kann die Kommunikation durch ein drahtloses System und/oder durch Verwendung der Stromleitungen erfolgen. Manche Sensorsignale können aus Sicherheitserfordernissen separat über Draht übertragen werden. Die Lenk- und Bremssysteme empfangen Fahrzeugdynamikbefehle auf hohem Niveau von der Hauptsteuereinheit, die auch als ein mögliches Gateway für andere Fahrzeuginformation wirken kann. Die Systemarchitektur und -topologie erlaubt es, daß mehr als ein Fehler auftreten kann, ohne grundlegende Brems- und Lenkfunktionen zu verlieren. Sollte beispielsweise die Lenkeinrichtung ausfallen, können die Vorderbremsen unabhängig betätigt werden, um ein Lenken zu ermöglichen. Sollte ähnlich eine der Vorderbremsen ausfallen, kann das Lenksystem während des Bremsens betätigt werden, um jegliches Giermoment zu kompensieren. Die Hauptsteuereinheit kann auch dazu verwendet werden, Ausfälle zu speichern, und meldet sofort bestimmte Ereignisse einem sicheren Ort außerhalb des Fahrzeugs.The The present invention provides a new topology and composition for communication networking, signal division, security and integration ready by physical units. In the first embodiment The main communication consists of two independent bus systems with different ones Run protocols (in a heterogeneous concept). At the second Embodiment can communication by a wireless system and / or by use the power lines take place. Some sensor signals may be off Security requirements are transmitted separately via wire. The steering and brake systems receive vehicle dynamics commands at a high level from the main control unit, which also acts as a possible gateway for others Vehicle information can act. The system architecture and topology allows more can occur as a failure, without basic braking and steering functions to lose. For example, should the steering device fail, can they Independent front brakes actuated to enable steering. Should be similar If one of the front brakes fails, the steering system can during the Braking actuated to compensate for any yaw moment. The main control unit can also be used to save failures and reports Immediately make certain events a safe place outside of the vehicle.
