Description
Schaltanordnung zum Auslösen von Notschaltfunktionen beiSwitching arrangement for triggering emergency switching functions at
Kraftfahrzeugen Die Erfindung bezieht sich auf eine Schaltanordnung zum Auslösen von Notschaltfunktionen bei Kraftfahrzeugen, mit Notschaltern, die durch jeweils einen Beschleunigungsgeber gesteuert bei oder nach einer anormalen Beschleunigung zugeordnete Ausrüstungsteile aus- bzw. einschalten, und mit einem Airbag, der durch mindestens einen separaten Beschleunigungsgeber auslösbar ist.Motor vehicles The invention relates to a switching arrangement for triggering emergency switching functions in motor vehicles, with emergency switches that controlled by an accelerometer at or after an abnormal Switch the equipment assigned to acceleration off or on, and with a Airbag that can be triggered by at least one separate acceleration sensor.
Eine derarte Schaltanordnung ist bei Kraftfahrzeugen mit einem Airbag allgemein bekannt. Die Ausrüstungsteile sind dabei z. B. die Kraftstoffpumpe, die bei einem Unfall ausgeschaltet wird, sowie die Warnblinkanlage, die dabei eingeschaltet wird. Ferner kann auch eine ggf. vorhandene Zentralverriegelungsvorrichtung entriegelt werden. Die für die jeweiligen Notschalter vorgesehenen Beschleunigungsgeber besitzen in der Regel eine unterschiedliche Ansprechschwelle. Dies kann dazu führen, daß bei einem Unfall nicht alle Notschalter gesteuert werden. Dadurch kann beispielsweise die Kraftstoffpumpe eingeschaltet und damit eine Brandgefahr bestehen bleiben. Legt man andererseits die Einschaltschwellen der einzelnen Beschleunigungsgeber so niedrig, daß sie bei einem Unfall mit Sicherheit ansprechen, so kann auch diese Maßnahme zu Fehlfunktionen führen. Bei einer starken, nicht durch einen Unfall bedingten Bremsung des Kraftfahrzeugs können einzelne Beschleunigungsgeber dann bereits ansprechen und in dann unerwünschter Weise die zugeordneten Notschalter steuern.Such a switching arrangement is in motor vehicles with an airbag well known. The pieces of equipment are z. B. the fuel pump that is switched off in the event of an accident, as well as the hazard warning lights that are switched on will. Furthermore, any central locking device that may be present can also be unlocked will. Have the acceleration sensors provided for the respective emergency switch usually a different response threshold. This can lead to not all emergency switches are controlled in the event of an accident. This can, for example the fuel pump is switched on and there is still a risk of fire. Lays on the other hand, the switch-on thresholds of the individual accelerometers are so low that that they respond with certainty in the event of an accident, this measure can also be used to malfunction to lead. With a strong one, not one Accident-related braking of the motor vehicle can individual acceleration sensors then already address and then in an undesirable manner the assigned emergency switch steer.
Der Erfindung liegt die Aufgabe zugrunde, eine Schaltanordnung der eingangs genannten Art zu schaffen, die mit geringem Aufwand eine Fehlsteuerung der Notschalter mit großer Sicherheit verhindert.The invention is based on the object of a switching arrangement of To create the type mentioned at the outset, which can be miscontrolled with little effort the emergency switch prevents with great certainty.
Die Erfindung löst diese Aufgabe dadurch, daß der Airbag-Beschleunigungsgeber auch die Notschalter steuert. Damit wird einerseits die Sicherheit vor einer Fehlauslösung der Notschalter erhöht. Airbag-Beschleunigungsgeber haben nämlich mittlerweile einen derart hohen technischen Stand erreicht, daß sie tatsächlich nur bei einem Unfall ansprechen, da sie eindeutig zwischen einer starken Bremsung und einer unfallbedingten negativen Beschleunigung des Kraft fahrzeugs unterscheiden kdnnen. Andererseits können alle Notschalter durch diesen einen Beschleunigungsgeber gesteuert werden, so daß individuelle Bçsehleunigungsgeber entfallen.The invention solves this problem in that the airbag acceleration sensor also controls the emergency switch. On the one hand, this provides security against false tripping the emergency switch increases. Airbag accelerators now have one reached such a high technical standard that it actually only works in an accident address, as they clearly distinguish between heavy braking and an accident-related one negative acceleration of the motor vehicle can distinguish. on the other hand all emergency switches can be controlled by this one acceleration sensor, so that individual accelerometers are not required.
Die Ansteuerung der Notschalter kann gleichzeitig mit der des Airbags erfolgen. Dies hat den Vorteil, daß die zugeordneten Ausrüstungsteile in der gewünschten Weise ge schaltet werden, bevor beispielsweise eine durch Deformation des Kraftfahrzeugs bedingte Leitungsunberbres chung eine Ansteuerung der Notschalter bzw. Einschalten der Ausrüstungsteile unmöglich macht. Dabei wird von der Eigenschaft eines üblichen Airbag-Beschleunigungsgebers, besonders schnell anzusprechen, Gebrauch gemacht.The emergency switch can be activated at the same time as the airbag take place. This has the advantage that the associated pieces of equipment in the desired Way ge are switched before, for example, a deformation of the motor vehicle conditional line uninterrupted triggering of the emergency switch or switching on which makes pieces of equipment impossible. It is of the property of a usual Airbag accelerator to respond particularly quickly, made use of.
üblicherweise ist für den Airbag ein Steuergerät vorgesehen, an dem der Beschleunigungsgeber angeschlossen ist.Usually a control unit is provided for the airbag on which the accelerometer is connected.
Das Steuergerät beinhaltet beispielsweise meist auch einen sogenannten SAFING SENSOR, der einerseits noch empfindlicher als der Beschleunigungsgeber auf Verzögerungen des Kraftfahrzeugs anspricht, andererseits bei einem nicht unfallbedingten Kurzschluß in der Leitung des Beschleunigungsgebers eine Fehlauslösung des Airbags verhindert. Ist das Steuergerät nun so ausgelegt, daß es auch die Notschalter ansteuert, so ist hierfür keine gesonderte Auswerteelektronik erforderlich und man kann die im Steuergerät enthaltene Auswerteelektronik und die angesprochenen weiteren Sicherheits-Schaltmaßnahmen des Steuergeräts auch für die Notschalter ausnutzen.For example, the control device usually also includes a so-called SAFING SENSOR, which on the one hand is even more sensitive than the acceleration sensor Delays of the motor vehicle responds, on the other hand in a non-accident-related Short circuit in the line of the accelerator, an incorrect deployment of the airbag prevented. If the control unit is now designed in such a way that it also activates the emergency switch, so no separate evaluation electronics are required for this and you can use the Evaluation electronics contained in the control unit and the other safety switching measures mentioned of the control unit can also be used for the emergency switch.
Ein derartiges Steuergerät überwacht üblicherweise auch den Stromkreis für den Airbag und schaltet bei einem Fehler eine Kontrolleuchte ein. Auch diese Funktion des Steuergeräts läßt sich im Rahmen der Erfindung zur Erhöhung der Sicherheit einer Auslösung der Ausrüstungsteile ausnutzen. Hierbei überwacht das Steuergerät auch die Stromkreise für die Notschalter und/oder für die Ausrüstungsteile und schaltet im Störfall ebenfalls die Kontrolleuchte ein. Dadurch kann sichergestellt werden, daß die Ausrüstungsteile bei einem Unfall in der erforderlichen Weise geschaltet werden bzw. daß eine stromkreisbedingte Nicht-Schaltung dieser Teile rechtzeitig signalisiert wird.Such a control device usually also monitors the circuit for the airbag and switches on a control lamp in the event of a fault. These too Function of the control device can be used within the scope of the invention to increase security exploit a tripping of the equipment. The control unit monitors this also the circuits for the emergency switches and / or for the equipment and switches in the event of a fault, the control light also comes on. This can ensure that the equipment is switched in the required manner in the event of an accident or that a circuit-related non-switching of these parts in time is signaled.
Die Erfindung ist anhand eines in der Zeichnung dargestellten Ausführungsbeispiels weiter erläutert. Ausrüstungsbauteile wie Benzinpumpenrelais, Zentralverriegelungsvorrichtung und Warnblinkanlage werden dabei durch ein Steuergerät für einen Airbag bei einem Unfall geschaltet.The invention is based on an embodiment shown in the drawing further explained. Equipment components such as fuel pump relay, central locking device and hazard warning lights are thereby controlled by a control unit for an airbag at a Accident switched.
Drei nicht dargestellte Gasgeneratoren für zwei ebenfalls nicht dargestellte Airbags eines Kraftfahrzeugs werden bei einem Unfall durch drei Zündpillen 1, 2 und 3 gezündet.Three gas generators, not shown, for two, also not shown In the event of an accident, the airbags of a motor vehicle are triggered by three squibs 1, 2 and 3 ignited.
Von zwei im Frontbereich des Kraftfahrzeugs gelegenen, als Schalter dargestellten Frontsensoren 4 und 5 wird dabei mindestens einer geschlossen. In einem als elektrische Leitung 6 dargestellten Zündkreis fließt dann von einer nicht dargestellten Batterie Strom durch die Zündpillen 1 bis 3.Of two located in the front area of the motor vehicle, as switches The front sensors 4 and 5 shown here are closed at least one. In an ignition circuit shown as an electrical line 6 then does not flow from one Battery current shown through the squibs 1 to 3.
Abschnitte der Leitung 6 verlaufen in einem Steuergerät 7 für den Airbag. Das Steuergerät enthält als zentrale Einheit einen schematisch dargestellten Mikroprozessor 8, der über diese Leitungsabschnitte und zusätzliche Anschlüsse den Zündkreis abschnittsweise mit Strom- bzw. Spannungsimpulsen beaufschlägt und damit den Zündkreis auf Leitungsfehler überprüft. Liegt ein derartiger Fehler vor, so wird eine Kontrolleuchte 9 durch den Mikroprozessor 8 eingeschaltet.Sections of the line 6 run in a control unit 7 for the Airbag. The control unit contains a schematically illustrated central unit Microprocessor 8, the over these line sections and additional connections The ignition circuit is subjected to current or voltage pulses in sections and thus the ignition circuit checked for line faults. If there is such an error, so a control lamp 9 is switched on by the microprocessor 8.
Der Mikroprozessor 8 besitzt einen weiteren Ausgang 10 für einen Schalttransistor 11, an dem Relaisspulen 12, 13 und 14 über eine Steuerleitung 15 angeschlossen sind. Diese schalten über als Notschalter dienende Relaiskontakte nicht dargestellte Ausrüstungsteile. Die Relaisspule 12 schaltet damit eine nicht dargestellte Kraftstoffpumpe, die Relaisspule 13 eine Zentralverriegelungsvorrichtung und die Relaisspule 14 eine Warnblinkanlage.The microprocessor 8 has a further output 10 for a switching transistor 11, to which relay coils 12, 13 and 14 are connected via a control line 15. These switch over equipment parts not shown, which serve as emergency switches. The relay coil 12 thus switches a fuel pump (not shown), the relay coil 13 a central locking device and the relay coil 14 a hazard warning light system.
Bei einer unfallbedingten anormalen Beschleunigung des Kraftfahrzeugs wird mindestens einer der Frontsensoren 4 und 5 geschlossen. Die Zündpillen 1 bis 3 zünden die Airbags. Gleichzeitig steuert der Mikroprozessor 8 den Schalttransistor 11 an. Über die Steuerleitung 15 werden die Relaisspulen 12 bis 14~erregt. Dadurch wird gleichzeitig mit dem Zünden des Airbag die Benzinpumpe abgeschaltet, die Zentralverriegelungsvorrichtung im Sinne einer Entriegelung geschaltet und die Warnblinkanlage eingeschaltet.In the event of abnormal acceleration of the motor vehicle as a result of an accident at least one of the front sensors 4 and 5 is closed. The primers 1 to 3 ignite the airbags. At the same time, the microprocessor 8 controls the switching transistor 11 at. The relay coils 12 to 14 ~ are excited via the control line 15. Through this If the fuel pump is switched off at the same time as the airbag is ignited, the central locking device switched in the sense of unlocking and switched on the hazard warning lights.
Durch die Schaltung der genannten Ausrüstungsteile mit Hilfe des Steuergeräts für den Airbag wird eine Fehlschaltung dieser Teile sicher vermieden. Die Ausrüstungsteile werden nur dann geschaltet, wenn auch der Airbag gezündet wird. By switching the equipment mentioned with the help of the The control unit for the airbag reliably prevents these parts from switching incorrectly. The equipment is only switched if the airbag is also deployed.
Wie in der Fig. angedeutet, ist innerhalb des Steuergeräts 7 auch ein SAFING-SENSOR vorgesehen, der bei einem nichtunfallbedingten Masseschluß des Zündkreises (Leitung 6) eine Zündung der Airbags und damit Einschalten der Ausrüstungsteile verhindert. As indicated in the figure, is within the control unit 7 also a SAFING-SENSOR is provided, which in the event of a non-accident-related short to ground of the Ignition circuit (line 6) an ignition of the airbags and thus switching on the equipment prevented.
Wie ohne weiteres zu erkennen, lassen sich mit Hilfe des Mikroprozessors 8 auch die Steuerleitung 15 und die daran angeschlossenen elektrischen Teile überwachen. Hierzu ist lediglich analog zur Überwachung des Zündkreises ein Leitungsabgriff zwischen einzelnen Abschnitten der Steuerleitung 15 bzw. der daran angeschlossenen Teile erforderlich.As can be seen without further ado, with the help of the microprocessor 8 also monitor the control line 15 and the electrical parts connected to it. For this purpose, there is only a line tap analogous to the monitoring of the ignition circuit between individual sections of the control line 15 or those connected to it Parts required.
Diese Leitungsabschnitte können durch den Mikroprozessor 8 gesteuert mit Hilfe von Strom bzw. Spannungsimpulsen auf elektrische Fehler untersucht werden. Bei einem Fehler kann ebenfalls die Kontrolleuchte 9 eingeschaltet werden. These line sections can be controlled by the microprocessor 8 can be examined for electrical faults with the aid of current or voltage pulses. In the event of an error, the control lamp 9 can also be switched on.
