Abstract

The method involves measuring the acceleration acting on a vehicle using an acceleration sensor (2.1,2.2). The acceleration signal, or preferably its integral is compared with a variable triggering threshold. At least one pre-crash sensor (1.1,1.2) records the variation of the relative speed or distance of objects within a defined proximity of the vehicle. If the relative speed is detected to be above a given threshold or the distance is detected to be below a given threshold, this is identified as a safety critical condition and the triggering threshold is reduced.

Description

Die Erfindung betrifft ein Verfahren zur Aufprallerkennung gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a method for impact detection according to the Preamble of claim 1.

Verfahren zur Aufprallerkennung werten die Beschleunigungssignale eines Beschleunigungssensors aus und entscheiden, ob ein sicherheitskritischer Aufprall vorliegt und der Airbag bzw. andere Insassenschutzeinrichtungen ausgelöst werden müssen.Impact detection methods evaluate the acceleration signals Acceleration sensor and decide whether a safety-critical There is an impact and the airbag or other occupant protection devices must be triggered.

Die DE-OS 39 24 507 lehrt bereits ein Verfahren zur Auslösung von Rückhal­ temitteln, bei dem der Auslöseschwellwert zur Anpassung an die besondere Unfallsituation in Abhängigkeit von Betriebsparametern des Fahrzeuges veränderbar ist. Als Problem wurde dabei erkannt, daß die auslösende Meß­ größe, das Integral der Beschleunigung über ein Zeitfenster, eine gewisse Zeit benötigt, um den Schwellwert zu erreichen. Da jedoch ggf. die Aktivie­ rung von Insassenschutzeinrichtungen sehr schnell erfolgen muß, lehrt die Schrift die Anpassung des Auslöseschwellwertes. Jedoch ist der Schrift nicht zu entnehmen, wie die Zustandsgrößen zur Anpassung ermittelt werden sollen.DE-OS 39 24 507 already teaches a method for triggering back means at which the trigger threshold for adaptation to the particular Accident situation depending on the operating parameters of the vehicle is changeable. It was recognized as a problem that the triggering measurement size, the integral of the acceleration over a time window, a certain Time needed to reach the threshold. However, because of the activation must be done very quickly, teaches the Font the adjustment of the trigger threshold. However, the writing is not see how the state variables for adaptation are determined should.

Auch der Patentschrift DE 41 17 811 C2 ist die Veränderung des Auslöse­ schwellwertes zu entnehmen, falls die Beschleunigungsdifferenz gewisse Schwellwerte übersteigt. Dieses Verfahren bietet den Vorteil, mittels der Be­ schleunigungsdifferenz sicherer zwischen ungefährlichen Niedergeschwin­ digkeitsunfällen und sicherheitskritischen Hochgeschwindigkeitsunfällen unterscheiden zu können. Nachteilig ist jedoch, die zur Ermittlung der Be­ schleunigungsdifferenz erforderliche zeitliche Verzögerung sowie der komplexe Aufbau, der Schieberegister und entsprechende Auswerteeinrich­ tungen vorsehen muß. The patent DE 41 17 811 C2 is also the change in the trigger threshold value if the acceleration difference certain Thresholds exceeded. This method has the advantage of using the Be Acceleration difference between safe low speed accidents and safety-critical high-speed accidents to be able to distinguish. It is disadvantageous, however, that for determining the loading acceleration difference required time delay and the complex structure, the shift register and corresponding evaluation device must provide provisions.  

Des weiteren Ansätze zur Entwicklung von sogenannten Precrash-sensoren bekannt, welche bereits vor dem eigentlichen Zusammenstoß (Crash) das Herannahen von Objekten erkennen. So wurde auf der internationalen Kon­ ferenz "Advanced Microsystems for Automotive Application" 2./3. 12. 1996 in Berlin von N. Ancona u. a. unter dem Titel "An Optical Mircosystem for Pre­ dictive Crash Sensing" ein optisches Precrashsensorsystem vorgestellt. Dabei werden jedoch die Sicherheitseinrichtungen bereits direkt von den Pre­ crashsensoren aktiviert, was die Gefahr von Fehlauslösungen beispielsweise bei Beinahezusammenstössen extrem erhöht. Dies kann gegebenenfalls die Reaktionsfähigkeit des Fahrers gerade in dieser sicherheitskritischen Situa­ tion stark beeinträchtigen und ist daher zu vermeiden.Furthermore approaches to the development of so-called pre-crash sensors known which already before the actual collision (crash) Detect approaching objects. So at the international con conference "Advanced Microsystems for Automotive Application" 2nd / 3rd 12. 1996 in Berlin by N. Ancona u. a. under the title "An Optical Micro System for Pre dictive Crash Sensing "presented an optical pre-crash sensor system However, the safety devices are already used directly by the Pre crash sensors activated, which increases the risk of false triggering, for example extremely increased in near collisions. This can, if necessary Responsiveness of the driver in this safety-critical situation tion and should therefore be avoided.

Aufgabe der Erfindung ist es daher, ein weiteres Verfahren zur Aufpraller­ kennung aufzuweisen, welches eine schnelle Aktivierung der Insassenschutzeinrichtungen gewährleistet und die Gefahr von Fehlauslösungen verrin­ gert.The object of the invention is therefore a further method for impact Identify which rapid activation of the occupant protection devices guaranteed and reduce the risk of false tripping device.

Diese Aufgabe ist durch die kennzeichnenden Merkmale des Patentan­ spruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind den Un­ teransprüchen zu entnehmen.This task is due to the characterizing features of the patent spell 1 solved. Advantageous developments of the invention are the Un claims.

Es werden die Precrash-Sensoren zur Beeinflussung der veränderbaren Auslöseschwelle verwendet. Die Auslöseschwelle wiederum wird, wie bei den derzeit eingesetzten Verfahren der Aufprallerkennung, mit einem Be­ schleunigungssignal eines Beschleunigungssensors oder einem daraus abge­ leiteten Signal verglichen.There are the pre-crash sensors to influence the changeable trigger threshold used. The trigger threshold, in turn, is the same as for the currently used methods of impact detection, with a loading acceleration signal from an acceleration sensor or one of them conducted signal compared.

Erkennt der Precrash-Sensor innerhalb eines Nahbereichs, der bspw. bereits schon durch die maximal mögliche Meßentfernung des Precrash-Sensors vorgegeben ist, durch Vergleich mit entsprechenden Schwellwerten einen sicherheitskritischen Zustand, so wird die Auslöseschwelle herabgesetzt. Die Auslösung erfolgt jedoch erst nachdem das Beschleunigungssignal oder das daraus abgeleitete Signal die Auslöseschwelle überschreitet.The pre-crash sensor detects within a close range, for example already already by the maximum possible measuring distance of the pre-crash sensor is given, by comparison with corresponding threshold values safety-critical state, the trigger threshold is reduced. The However, triggering takes place only after the acceleration signal or signal derived therefrom exceeds the trigger threshold.

Die Herabsetzung der Auslöseschwelle ist dabei so zu wählen, daß die Insas­ senschutzeinrichtungen umgehend aktiviert werden, wenn das Beschleuni­ gungssignal nur bereits erste, über das normale Fahrverhalten hinausge­ hende Beschleunigungskräfte anzeigt.The lowering of the trigger threshold is to be chosen so that the Insas safety devices are activated immediately when the acceler only the first signal that goes beyond normal driving behavior accelerating forces.

Durch die Zuordnung der Precrash-Sensoren zu je einer Fahrzeugseite kön­ nen gezielt die Auslöseschwellen des Beschleunigungssignals des der jewei­ ligen Fahrzeugseite zugeordneten Beschleunigungssensors oder gezielt ent­ sprechend der Fahrzeugseite zugeordnete Insassenschutzeinrichtungen, bspw. Side-Airbags aktiviert werden.By assigning the pre-crash sensors to one side of the vehicle the triggering thresholds of the acceleration signal of the respective  Accelerometer assigned to the vehicle side or specifically ent occupant protection devices assigned to the vehicle side, For example, side airbags can be activated.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels sowie der Figuren erläutert.The invention is described below using an exemplary embodiment as well of the figures explained.

Es zeigen:Show it:

Fig. 2 zeitlich er Verlauf der Systemgrößen. Fig. 2 temporally he course of the system variables.

Fig. 1 zeigt eine schematische Darstellung einer Anordnung zur Durchfüh­ rung des Verfahrens. Bei dem Ausführungsbeispiel wurden zwei Precrash-Sen­ soren 1.1 und 1.2 verwendet, die der ersten und zweiten Fahrzeugseite zugeordnet sind. Entsprechend sind auch zwei Beschleunigungssensoren 2.1 und 2.2 verwendet worden. Die Zentraleinheit 3 steuert und empfängt die Signale der Precrash- und Beschleunigungssensoren (1 und 2) und leitet die­ se weiter. So werden die Auslöseschwellen für die einzelnen Beschleuni­ gungssignale entsprechend der Ergebnisse der Precrash-Sensoren angepaßt. Überschreitet eines der Beschleunigungssignale die Auslöseschwelle, so wird von der Zentraleinheit 3 entschieden, welche der Insassenschutzeinrichtun­ gen, dargestellt in diesem Schema als 4.1 und 4.2, ausgelöst werden. Dabei werden einerseits die der jeweiligen Fahrzeugseite zugeordneten Sicher­ heitseinrichtungen sowie eventuell übergeordnete Sicherheitseinrichtun­ gen 5, wie Front-Airbag oder Benzinabschaltung angesprochen, die jedoch nicht im einzelnen dargestellt sind. Fig. 1 shows a schematic representation of an arrangement for performing the method. In the exemplary embodiment, two pre-crash sensors 1.1 and 1.2 were used, which are assigned to the first and second vehicle sides. Accordingly, two acceleration sensors 2.1 and 2.2 have also been used. The central unit 3 controls and receives the signals from the pre-crash and acceleration sensors ( 1 and 2 ) and forwards them. So the trigger thresholds for the individual acceleration signals are adjusted according to the results of the pre-crash sensors. If one of the acceleration signals exceeds the trigger threshold, the central unit 3 decides which of the occupant protection devices, shown in this diagram as 4.1 and 4.2 , are triggered. On the one hand, the safety devices assigned to the respective vehicle side and any higher-level safety devices 5 , such as front airbag or gasoline cut-off, are addressed, but these are not shown in detail.

Fig. 2 zeigt nun den zeitlichen Verlauf der Systemgrößen. So wird der Ver­ lauf des vom Precrash-Sensor ermittelten relativen Abstandes zum Fahrzeug mit ΔS, die vom Beschleunigungssensor ermittelte Beschleunigung a und der Auslösebefehl 6 in ihrem zeitlichen Ablauf dargestellt. Fig. 2 shows the time course of the system variables. Thus, the course of the relative distance to the vehicle determined by the pre-crash sensor is represented by ΔS, the acceleration a determined by the acceleration sensor and the triggering command 6 are shown in their chronological sequence.

Zum Zeitpunkt t0 dringt ein Objekt in den Nahbereich des Fahrzeugs ein und der Abstand ΔS verringert sich immer mehr.At time t 0 , an object enters the near area of the vehicle and the distance ΔS decreases more and more.

Zum Zeitpunkt t1 unterschreitet der Abstand ΔS den Schwellwert S1, wor­ aufhin die Auslöseschwelle a von dem Wert a1 auf den deutlich niedrigeren Wert a2 gesetzt wird. At time t 1 , the distance ΔS falls below the threshold value S 1 , whereupon the trigger threshold a is set from the value a 1 to the significantly lower value a 2 .

Zum Zeitpunkt t2 erfolgt der Zusammenstoß, der zu einer Verformung der Knautschzonen des Fahrzeugs und zu Beschleunigungskräften führt, die ge­ genüber den im normalen Fahrbetrieb üblichen erhöht sind.At time t 2 , the collision takes place, which leads to a deformation of the crumple zones of the vehicle and to acceleration forces which are higher than those customary in normal driving.

Zum Zeitpunkt t3 erreicht das Beschleunigungssignal den nunmehr reduzier­ ten Wert a2 der Auslöseschwelle, so daß die Zentraleinheit den Auslösebe­ fehl 6 an bestimmte Insassenschutzeinrichtungen sendet.At time t 3 , the acceleration signal reaches the now reduced value a 2 of the triggering threshold, so that the central unit sends the triggering error 6 to certain occupant protection devices.

Wäre der alte Schwellwert a1 des Normalbetriebs beibehalten worden, wäre erst zum Zeitpunkt t4 die Auslösung erfolgt, wie in Fig. 2 angedeutet wird. Durch den hohen Schwellwert a1 wird im Normalbetrieb sichergestellt, daß nicht etwa Erschütterungen des Fahrzeugs durch Straßenunebenheiten oder ähnliches zur Auslösung führen.If the old threshold value a 1 of normal operation had been retained, the triggering would not have taken place until time t 4 , as is indicated in FIG. 2. The high threshold value a 1 ensures in normal operation that vibrations of the vehicle due to uneven roads or the like do not lead to triggering.

Die vorliegende Erfindung wird insbesondere bei kleineren Fahrzeugen und für die gezielte Ansteuerung von Seiten-Airbags eine wesentliche Verbesse­ rung der Auslösegenauigkeit bei gleichzeitig hoher Auslösegeschwindigkeit beitragen.The present invention is particularly applicable to smaller vehicles and a significant improvement for the targeted control of side airbags tripping accuracy with high tripping speed contribute.
