Als Nachteil bei den durch die Schriften offenbarten Lösungen kann betrachtet werden, dass bei einer Vereinheitlichung/Kombination der Airbag-, ABS- & ESP-Funktionalität zu einem System (einer Baueinheit) bei der Montage der Baugruppe im Fahrzeug ein Problem entsteht, dass darin besteht, dass der gewählte Montageort, nur immer für eine Funktionalität ein Optimum darstellt, da der bevorzugte Montageort für das Airbagsteuergerät auf dem Tunnel im Fahrgastraum ist (wegen der Beschleunigungs-Sensierung), wohingegen der bevorzugte Montageort für das ABS-/ESP-Steuergerät im Motorraum in unmittelbarer Nähe des Bremskraftverstärkers bzw. der mechanischen Ventilansteuerung ist.When Disadvantage of the solutions disclosed by the writings be considered that in a unification / combination the airbag, ABS & ESP functionality to one System (of a unit) during assembly of the assembly in the vehicle a problem arises that is that the chosen mounting location, only ever for a functionality represents an optimum, since the preferred mounting location for the airbag control unit on the Tunnel in the passenger compartment is (because of the acceleration sensing), whereas the preferred installation site for the ABS / ESP control unit in the engine room in the immediate vicinity of the brake booster or the mechanical valve control is.
Die Aufgabe der Erfindung ist es daher, eine Lösung zu schaffen, mittels dieser eine Kombination der einzelnen Funktionalitäten in einem gemeinsamen System ermöglicht wird, ohne dass hierdurch Einschränkungen an den einzelnen System-Funktionalitäten entstehen.The The object of the invention is therefore to provide a solution by means of this a combination of the individual functionalities in a common system allows without any restrictions on the individual system functionalities.
Diese Aufgabe wird durch die Merkmale der unabhängigen Ansprüche gelöst. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen, wobei auch Kombinationen und Weiterbildungen einzelner Merkmale untereinander denkbar sind.These The object is solved by the features of the independent claims. advantageous Further developments of the invention will become apparent from the dependent claims, wherein also combinations and developments of individual features with each other are conceivable.
Ein wesentlicher Gedanke der Erfindung besteht darin, dass zur Vermeidung oben angeführter Nachteile/Probleme, eine System-Auslegung (Partition) geschaffen wird, die im wesentlichen eine Kombination der Airbag-, ABS- & ESP-Funktionalität in einem gemeinsamen Steuergerät ermöglicht, wobei zur Vermeidung von einer Vielzahl von Leitungen, durch diese im Betriebsfall (Bremsfall) hohe Ströme fließen und entsprechende Störungen an die Umgebung aussenden würden (EMV), erfindungsgemäß mindestens eine ausgelagerte intelligente Aktorsteuereinheit (bspw. vor Ort im Motorraum) vorgeschlagen wird, um das Problem der unterschiedlichen erforderlichen Montageorte zu lösen.One essential idea of the invention is that to avoid above-mentioned disadvantages / problems, a system design (partition) is created that is essentially enables a combination of the airbag, ABS & ESP functionality in a common control unit, being to avoid a variety of lines, through these In case of operation (braking) high currents flow and corresponding faults would send out the environment (EMC), according to the invention at least an outsourced intelligent actuator control unit (eg locally in the engine compartment) is proposed to solve the problem of different to solve the required installation locations.
Die nachfolgende Lösung beschreibt eine Realisierung, bei dieser das gemeinsame Gehäuse des kombinierten Systems auf dem Tunnel im Fahrgastraum angeordnet ist, da an dieser Stelle eine optimale Beschleunigungserfassung (Sensierung) möglich ist.The subsequent solution describes a realization in which the common housing of the combined system is located on the tunnel in the passenger compartment, because at this point an optimal acceleration detection (sensing) is possible.
In einer nicht näher gezeigten Realisierungsform könnte anstatt des Tunnels als Montageort auch im Gegensatz der Bereich vor Ort im Motorraum gewählt werden, und die erforderlichen Sensorsignale in den Motorraum geleitet werden, wobei dieser Montageort infolge der erhöhten Umgebungstemperaturen nicht zu bevorzugen ist, weshalb diese Lösung in der weiteren Beschreibung auch nicht näher erläutert wird.In one not closer could be shown realization form instead of the tunnel as a mounting location also in contrast to the area chosen locally in the engine compartment be passed, and the required sensor signals in the engine compartment be, with this installation due to the increased ambient temperatures is not preferable, which is why this solution in the further description not closer either is explained.

Das Konzept erfordert andererseits in der Aktorsteuereinheit keine hohe Mikroprozessorleistung, wie dies im Steuergerät erforderlich ist, da hier nur die Steuerbefehle umgesetzt werden müssen und nicht die aufwändige Algorithmik zur Sensorsignalverarbeitung abgearbeitet wird.The On the other hand, concept does not require high in the actuator control unit Microprocessor performance, as required in the controller, since only here the control commands must be implemented and not the complex algorithms is processed for sensor signal processing.
