Stand der TechnikState of the art
Die Erfindung betrifft eine Vorrichtung, ein Steuergerät und ein Verfahren zur Detektion einer Kollision nach der Gattung der unabhängigen Patentansprüche.The The invention relates to a device, a control device and a Method for detecting a collision according to the preamble of the independent claims.
Aus
Offenbarung der ErfindungDisclosure of the invention
Die erfindungsgemäße Vorrichtung zur Detektion einer Kollision bzw. das erfindungsgemäße Steuergerät bzw das erfindungsgemäße Verfahren zur Detektion einer Kollision mit den Merkmalen der unabhängigen Patentansprüche haben demgegenüber den Vorteil, dass eine solche Insassensensierung ein Signal liefert, das auch zur Detektion einer Kollision dient. Dabei wertet eine Auswerteschaltung, beispielsweise ein Mikrocontroller oder Mikroprozessor das Signal dahingehend aus, dass die zeitliche Änderung des Signals mithin seine zeitliche Ableitung zur Kollisionsdetektion verwendet wird. Gewichtsmesssensoren messen die Kraft im Fahrzeug vertikal, also in z-Richtung. Bei einer Kollision kommt es zu einer Vorverlagerung eines Fahrzeuginsassen, was sich in einer Änderung des Kraftflusses ausdrückt. Diese Änderung wird erfindungsgemäß zur Kollisionsbestimmung ausgenutzt. Dabei kommen vorzugsweise absolut messende Sensoren zum Einsatz, die innerhalb der Sitzstruktur verbaut sind und nunmehr im Allgemeinen als iBolt bekannt sind. Der Aufbau eines solchen Kraftmesselements, das die Insassensensierung ausmacht, ergibt die Möglichkeit, die Kraft in z-Richtung zu erfassen. Momente um die x- bzw. y-Achse sowie die Kräfte in x- und y-Richtung werden kompensiert und unterdrückt. Üblicherweise können vier solche Kraftmesselemente pro Sitz verwendet werden. Für die Durchführung der Erfindung ist jedoch nur ein Sensor notwendig, um die zeitliche Änderung des Messsignals auszuwerten. Die Verwendung von zwei Kraftmessbolzen kann vorzugsweise zur Front- bzw. Heck-Crasherkennung verwendet werden.The inventive device for detecting a collision or the control device according to the invention or the inventive method for Detecting a collision with the features of the independent claims In contrast, the advantage that such occupant sensing provides a signal which also serves to detect a collision. It evaluates one Evaluation circuit, such as a microcontroller or microprocessor the signal to the effect that the temporal change of the signal its time derivative is used for collision detection. Weight measuring sensors measure the force in the vehicle vertically, ie in the z direction. In a collision, it comes to a forward displacement of a vehicle occupant, which is expressed in a change in the power flow. This change is inventively collision determination exploited. Preferably absolute measuring sensors come here used, which are installed within the seat structure and now generally known as iBolt. The construction of such Force measurement, which makes up the occupant sensing, gives the Possibility to Force in z-direction to capture. Moments about the x or y axis as well as the forces in the x and y directions are compensated and suppressed. Usually four such force measuring elements are used per seat. For the implementation of Invention, however, only one sensor is necessary to the temporal change to evaluate the measurement signal. The use of two force measuring pins can preferably be used for front or rear crash detection become.
Eine durch einen Crash bzw. Kollision hervorgerufene Verzögerung führt aufgrund der Massenträgheit des Insassen zu einer Vorverlagerung. Diese Vorverlagerung kann über einen Kraftmessbolzen oder eine andere gewichtsmessende Sensorik erfasst werden. Das bedeutet physikalisch eine signifikante Änderung des von ihm gemessenen Signals, welches mit dem Gewicht korreliert. Diese Änderung lässt sich erfindungsgemäß als Plausibilisierung und/oder als Kollisionsdetektion in einem Algorithmus zur Auslösung von Personenschutzmitteln einsetzen.A Crash-induced deceleration results the inertia of the occupant to a forward displacement. This forward displacement can be over a Force measuring pin or other weight-measuring sensors detected become. That means physically a significant change the signal measured by him, which correlates with the weight. This change can be according to the invention as a plausibility check and / or as collision detection in an algorithm for triggering Use personal protective equipment.
Von Vorteil ist die Einsparung von Beschleunigungssensoren, denn es kann beispielsweise der Beschleunigungssensor eingespart werden, der in Heckrichtung empfindlich ist und der eine Plausibilisierung für den Heck-Crash bzw. auch für den Front-Crash darstellen soll. Die Einführung der Erfindung vermeidet so die Verzögerung des Insassen durch diese Plausibilisierung, denn die Erfassung der Kraftmessbolzen erfolgt in analoger Form. Damit kann durch die Einsparung von Sensoriken eine deutliche Reduktion der Hardwarekosten gegeben sein.From Advantage is the saving of acceleration sensors, because it For example, the acceleration sensor can be saved, which is sensitive in the tail direction and a plausibility check for the Heck crash or for to represent the front crash. The introduction of the invention avoids so the delay the occupant through this plausibility check, because the detection of the force pin takes place in analogous form. This can be achieved by saving on sensors be given a significant reduction in hardware costs.
Durch den Einsatz von vier Kraftmessbolzen kann mittels der vier Kraftmessbolzen eine deutlich bessere Plausibilisierung durchgeführt werden. Dadurch ergibt sich der Vorteil einer erhöhten Robustheit bei einer Auslösung der Personenschutzmittel.By The use of four force measuring pins can be done by means of four force measuring pins a significantly better plausibility check will be carried out. This results the advantage of an increased Robustness in a trip the personal protective equipment.
Das erfindungsgemäße Steuergerät weist eine Schnittstelle auf, die die Signale beispielsweise des Kraftmessbolzens bereitstellt.The Control unit according to the invention has a Interface on which the signals, for example, the force measuring bolt provides.
Durch die in den abhängigen Ansprüchen aufgeführten Maßnahmen und Weiterbildungen sind vorteilhafte Verbesserungen der in den unabhängigen Patentansprüchen angegebenen Vorrichtung zur Detektion einer Kollision bzw. der in den unabhängigen Patentansprüchen angegebenen Verfahrens zur Detektion einer Kollision möglich.By those in the dependent Claims listed measures and developments are advantageous improvements in the independent claims specified device for detecting a collision or in the independent one claims specified method for detecting a collision possible.
Besonders vorteilhaft ist, dass die zeitliche Änderung des Signals einer Schwellwertentscheidung unterzogen wird und so in einfacher Art und Weise die Detektionsauswertung geschehen kann. Dieser Schwellwert kann fest oder variabel sein. Daneben lassen sich anstatt oder zusätzlich weitere zeitliche Änderungen des Signals auswerten. Dazu gehören mehrfache Ableitungen des Signals, Varianzen, Schwankungsbreiten etc.Especially It is advantageous that the temporal change of the signal of a threshold value decision is subjected and thus in a simple way the detection evaluation can happen. This threshold can be fixed or variable. In addition, instead of or in addition to other temporal changes evaluate the signal. This includes multiple derivatives of the signal, variances, fluctuation ranges Etc.
Es ist weiterhin von Vorteil, dass gezählt wird, wie lange die zeitliche Ableitung über dem Schwellwert ist, um so genannte Misuse-Fälle wie ein Schlagloch oder eine Bordsteinüberfahrt auszublenden, die lediglich zu einem kurzzeitigen Überschreiten eines Schwellwertes führen. Daher ist die zeitliche Bewertung des Signals notwenig, um solche Misuse-Fälle ausschließen zu können.It is also advantageous that is counted how long the temporal Derivative over the threshold is so-called misuse cases like a pothole or a curb crossing hide, only for a short time crossing a threshold lead. Therefore, the temporal evaluation of the signal is necessary to such Misuse Falls exclude to be able to.
Vorteilhafterweise kann die Auswertung der zeitlichen Änderung des Signals zur Plausibilisierung eines Signals einer Crash-Sensorik verwendet werden. Dies erspart die Verwendung von einer zusätzlichen Crash-Sensorik.Advantageously, the evaluation of the temporal change of the signal used to check the plausibility of a crash sensor system. This saves the use of an additional crash sensor.
Darüber hinaus ist es von Vorteil, dass ein mechanischer Anschlag des Kraftmessbolzens, der als Überlastschutz genutzt wird, zur Kollisionsdetektion verwendet wird. Der Überlastschutz dient zur Sicherung des Sitzes bei einem Unfall. Auch dieser Anschlag kann vorzugsweise anhand der zeitlichen Änderung des Signals erkannt werden, indem bspw. ein Maximalwert erreicht wird. Auch die Form des Signals, die die zeitlichen Änderungen des Signals zeigt, kann im Sinne einer Mustererkennung zur Erkennung des Anschlags und damit zur Kollisionsdetektion verwendet werden.Furthermore it is advantageous that a mechanical stop of the force measuring bolt, as overload protection used for collision detection. The overload protection serves to secure the seat in the event of an accident. Also this stop can preferably be detected on the basis of the temporal change of the signal be achieved by, for example, a maximum value is reached. Also the form the signal that changes over time of the signal can, in the sense of a pattern recognition for detection of the attack and thus used for collision detection.

Erfindungsgemäß wertet der Mikrocontroller μC die zeitliche Änderung, sprich die zeitliche Ableitung des Signals von der Insassensensorik IB aus. Dieses Signal wird mit einem Schwellwert verglichen und wenn der Schwellwert überschritten wird, dann wird überprüft, wie lange dieser Schwellwert überschritten wird, um festzustellen, ob es sich um einem so genannten Misuse handelt oder um einen tatsächlichen Auslösefall. Darüber hinaus wird natürlich auch die Gewichtsinformation ausgewertet, um festzustellen, ob ein Airbag ausgelöst werden kann oder nicht. Darüber hinaus wertet der Mikrocontroller μC die Signale der Crash-Sensorik CS aus. Dafür werden die Sensorsignale auf bekannte Weise ausgewertet, wiederum mittels Kennlinien oder Schwellwerten. Neben der hier dargestellten ausgelagerten Sensorik ist es auch möglich, dass sich innerhalb des Steuergeräts SG1 eine Unfallsensorik befindet. Andere Komponenten, die zum Betrieb des Steuergeräts SG1 notwendig sind, aber für das Verständnis der Erfindung nicht, sind der Einfachheit halber vorliegend weggelassen worden. Die Daten von den Sesoriken CS bzw. IB werden über Punkt-zu-Punkt oder Bus-Verbindungen zum Steuergerät SG1 übertragen. Insbesondere für die Sensorik IB hat sich der bekannte LIN-Bus als vorteilhaft erwiesen.Evaluates according to the invention the microcontroller μC the temporal change, speak the time derivative of the signal from the occupant sensors IB off. This signal is compared with a threshold and when the threshold is exceeded will, then will be checked how long exceeded this threshold is to determine if it is a so-called misuse act or an actual Deployment case. About that Of course, too evaluated the weight information to determine if an airbag triggered can or not. About that In addition, the microcontroller μC evaluates the signals of the crash sensors CS off. Therefore the sensor signals are evaluated in a known manner, again by means of characteristic curves or threshold values. In addition to the one shown here outsourced sensors, it is also possible that within of the control unit SG1 is an accident sensor. Other components required for operation of the control unit SG1 are necessary, but for the understanding of The invention is not omitted here for the sake of simplicity Service. The data from the CS or IB sesorics are over point-to-point or transfer bus connections to the control unit SG1. Especially for the sensors IB has proven the well-known LIN bus to be advantageous.
Vorliegend wird eine Plausibilisierung mit dem Signal des Kraftmessbolzens bezüglich der Kollisionsdetektion durchgeführt. Es ist möglich, dass nur mit dem Kraftmessbolzen die Detektion der Kollision erfolgt. Anstatt von Beschleunigungssensoren können auch andere Sensoren wie Druck-, Körperschall- und Umfeldsensoren verwendet werden.present becomes a plausibility check with the signal of the force measuring bolt in terms of the collision detection performed. It is possible, that the collision is detected only with the force measuring bolt. Instead of acceleration sensors, other sensors such as Pressure, structure-borne noise and environmental sensors are used.
