Description

Die Erfindung betrifft einen Überrollsensor für ein Kraftfahrzeug.The invention relates to a rollover sensor for a motor vehicle.

Zur Vermeidung von schweren Verletzungen sind seit langem Insassen­ rückhaltesysteme, wie beispielsweise Airbag und Gurtstraffer, bekannt. Zur möglichst frühzeitigen Auslösung dieser Rückhaltesysteme sind kontaktlose Crashsensoren, auch als Precrash-Sensoren bezeichnet, bekannt, aus deren Signalen auf einen unvermeidlichen Unfall geschlossen werden kann, so daß bereits vor der tatsächlichen Kollision die Auslösung der Rückhaltesysteme beginnen kann. Weiter ist es bekannt, daß die Signale der Precrash-Sensorik bzw. eines Airbagsteuergerätes zum Ansteuern der Zentralverriegelung und zum Absprengen der Batterieklemmen verwendet werden. Der Sinn liegt darin, den potentiellen Helfern nach einem Unfall den Zugang zum Kraftfahrzeug und damit zu der verletzten Person zu erleichtern bzw. die Gefahr eines Fahrzeugbrandes zu minimieren. Weiter ist es bekannt, mittels der Precrash-Sensorik eine Notrufzentrale zu verständigen. Dazu wird beispielsweise mittels eines GSM-Moduls die Notrufnummer bis auf die letzte Nummer gewählt, falls die Precrash-Sensorik ein Signal liefert. Kommt es dann tatsächlich zu einer Kollision, wird die letzte Nummer gewählt, wobei mittels eines vorhandenen Navigationssystems eine zusätzliche Ortsangabe des Unfallortes abgesetzt werden kann. Voraussetzung für alle diese Hilfsmaßnahmen ist jedoch, daß die Precrash-Sensorik auch rechtzeitig eine Situation als Unfall einschätzt. Am häufigsten werden Beschleunigungssensoren verwendet, die auf die meist vor einem Unfall erfolgte Vollbremsung reagieren. Darüber hinaus sind Bildverarbeitungsgeräte bekannt, aus deren Informationen ein Prozeßrechner eine bevorstehende Kollision errechnet. Eine mögliche Unfallsituation, bei der die Precrash- Sensorik unter Umständen nicht zuverlässig anspricht, ist das Überschlagen des Kraftfahrzeuges. Daher besteht unfalltechnisch der Bedarf eines Überrollsensors zur Erfassung des Überschlages eines Kraftfahrzeuges. Andererseits besteht das Problem, daß ein weiterer Sensor mit entsprechender Auswertelogik in das Bordnetz zu integrieren ist, was aufgrund der zunehmenden Sensorik an Grenzen stößt.To avoid serious injuries have long been inmates restraint systems, such as airbags and belt tensioners, are known. As possible Early triggering of these restraint systems are contactless crash sensors, too referred to as pre-crash sensors, known from their signals on a inevitable accident can be closed so that even before the actual Collision can begin triggering the restraint systems. It is also known that the signals of the pre-crash sensor system or an airbag control unit for controlling the Central locking and used to detach the battery terminals. Of the The point is to give potential helpers access to the after an accident Motor vehicle and thus to facilitate the injured person or the risk of To minimize vehicle fire. It is also known by means of the pre-crash sensor system to notify an emergency call center. This is done, for example, by means of a GSM module the emergency number is dialed down to the last number if the pre-crash sensor system is on Signal delivers. If a collision actually occurs, the last number becomes selected, an additional using an existing navigation system The location of the accident location can be deducted. Requirement for all of these Aid measures, however, is that the pre-crash sensor system also be a situation in time assessed as an accident. Accelerometers are most commonly used react to the emergency braking that usually occurred before an accident. Beyond that Image processing devices known from the information of a process computer upcoming collision is calculated. A possible accident situation in which the pre-crash The sensor system may not respond reliably, is the rollover of the Motor vehicle. Therefore, in terms of accident technology, there is a need for a rollover sensor Detection of the rollover of a motor vehicle. On the other hand, there is the problem that integrate a further sensor with appropriate evaluation logic into the vehicle electrical system is what comes up against limits due to the increasing sensors.

Der Erfindung liegt daher das technische Problem zugrunde, einen Überrollsensor zu schaffen, der mit geringem schaltungstechnischen Aufwand realisierbar ist.The invention is therefore based on the technical problem of a rollover sensor create that can be implemented with little circuitry.

Die Lösung des technischen Problems ergibt sich durch die Merkmale des Patentanspruchs 1. Durch die Ausbildung des Überrollsensors als Abstandssensor mit vertikaler Auflösung kann auf eine bereits vorhandene Sensorik zurückgegriffen werden, so daß zur Implementierung nur eine der Abstandssensorik zugeordnete Signalauswerteeinheit softwaremäßig ergänzt und die elektrischen Verbindungen zu den ansteuerbaren Komponenten hergestellt werden müssen. Die Abstandssensoren können bereits Bestandteil verschiedener Fahrassistenz-Systeme, wie beispielsweise Abstands- und Geschwindigkeitsregelung oder Einparkhilfen, sein. Andererseits kann die Abstandssensorik für den Überrollsensor selbstverständlich auch als unifunktionale separate Einheit ausgebildet sein. Das gemeinsame Prinzip beruht darauf, daß ein Abstandssensor nicht nur zur horizontalen, sondern auch zur vertikalen Abstandsbestimmung einsetzbar ist. Diese vertikale Abtastung ist den meisten handelsüblichen Abstandssensoren aufgrund ihrer Abstrahlcharakteristik implizit. Anschaulich ist die vertikale Abstandsmessung eine Höhenmessung des Abstandssensors zur Bodenfläche. Bei einem Überschlagen des Kraftfahrzeuges ändert sich zwangsläufig auch die Position bzw. Höhe des Abstandssensors zur Bodenfläche, die vom Abstandssensor erfaßt und von einer nachgeschalteten Auswerteeinheit in ein Steuersignal umsetzbar ist. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The solution to the technical problem results from the characteristics of the Claim 1. By designing the rollover sensor as a distance sensor vertical resolution, an existing sensor system can be used, so that only one assigned to the distance sensor system for implementation Software evaluation unit added and the electrical connections to the controllable components must be manufactured. The distance sensors can already part of various driver assistance systems, such as distance and cruise control or parking aids. On the other hand, the Distance sensors for the rollover sensor are of course also available as unifunctional ones separate unit. The common principle is that a Distance sensor not only to the horizontal, but also to the vertical Distance determination can be used. This vertical scan is most commercially available distance sensors implicitly due to their radiation characteristics. The vertical distance measurement is clearly a height measurement of the Distance sensor to the floor surface. In the event of a rollover of the motor vehicle changes the position or height of the distance sensor to the floor surface inevitably changes, which is detected by the distance sensor and in a downstream evaluation unit Control signal can be implemented. Further advantageous embodiments of the invention result itself from the subclaims.

Die Erfindung wird nachfolgend anhand eines bevorzugten Ausführungsbeispiels näher erläutert. Die Figur zeigen:The invention is explained in more detail below on the basis of a preferred exemplary embodiment explained. The figure shows:

Fig. 1 ein Kraftfahrzeug bei normaler Fahrt und Fig. 1 is a motor vehicle during normal driving and

Fig. 2 das Kraftfahrzeug gemäß Fig. 1 während oder nach einem Überschlag. Fig. 2, the motor vehicle of FIG. 1 during or after rolling.

Das Kraftfahrzeug 1 umfaßt mindestens einen Abstandssensor 2, der derart am Kraftfahrzeug 1 angeordnet ist, daß dieser den Abstand zum Boden 3 erfaßt. Zur multifunktionalen Verwendung des Abstandssensors 2 ist dieser im vorderen Bereich des Kraftfahrzeuges 1 angeordnet. Der Abstandssensor 2 ist vorzugsweise als Radar- und/oder Lasersensor ausgebildet und mit einer nicht dargestellten Auswerteeinheit verbunden. Der Abstandssensor 2 sendet eine spezifische Strahlung aus und empfängt die von Objekten reflektierte Teilstrahlung. Aufgrund der Berücksichtigung von Laufzeit und Empfangswinkel der reflektierten Strahlung kann dann der Abstand und die Position eines Objektes bestimmt werden. Für die Funktion als Überrollsensor ist dabei besonders der vertikale Abstand zum Boden 3 von Interesse, aus dem auf die Höhe h1 des Abstandssensors 2 geschlossen werden kann. In der Fig. 2 ist das Kraftfahrzeug 1 nach einem Überschlag dargestellt, so daß nunmehr der Abstand vom Abstandssensor 2 zum Boden 3 h2 ist. Entsprechend der Abtastrate des Abstandssensors 2 nimmt dieser eine Reihe von Höhenwerten zwischen h1 und h2 auf. Die Absolutwerte der Höhenwerte h hängen zwar von der Art des Überschlagens ab, jedoch ist der Verlauf zwischen den Höhenwerten charakteristisch. Dieser Verlauf kann zur Unterstützung von Fehlalarmen ausgewertet werden. Fährt beispielsweise das Kraftfahrzeug 1 auf einer Straße mit vielen Schlaglöchern, so signalisiert der Abstandssensor 2 bei jedem Schlagloch eine sich verändernde Höhe. Aus dem Verlauf der Höhenwerte kann jedoch geschlossen werden, daß es sich ausschließlich um eine vertikale Auf- und Abbewegung und nicht um einen Überschlag handelt.The motor vehicle 1 comprises at least one distance sensor 2 , which is arranged on the motor vehicle 1 in such a way that it detects the distance from the floor 3 . For multifunctional use of the distance sensor 2 , it is arranged in the front area of the motor vehicle 1 . The distance sensor 2 is preferably designed as a radar and / or laser sensor and connected to an evaluation unit, not shown. The distance sensor 2 emits specific radiation and receives the partial radiation reflected by objects. The distance and the position of an object can then be determined on the basis of the propagation time and reception angle of the reflected radiation. The vertical distance from the floor 3 , from which the height h 1 of the distance sensor 2 can be concluded, is of particular interest for the function as a rollover sensor. In FIG. 2, the motor vehicle 1 is shown after a rollover so that now is the distance from the distance sensor 2 to the base 3 h 2. Depending on the sampling rate of the distance sensor 2 , the latter records a series of height values between h 1 and h 2 . The absolute values of the height values h depend on the type of rollover, but the course between the height values is characteristic. This course can be evaluated to support false alarms. For example, if the motor vehicle 1 is driving on a road with many potholes, the distance sensor 2 signals a changing height for each pothole. However, it can be concluded from the course of the altitude values that it is exclusively a vertical up and down movement and not a rollover.

Eine besonders vorteilhafte Ausgestaltung der Erfindung ergibt sich, wenn der Abstandsmesser 2 gleichzeitig als Precrash-Sensorik verwendet wird. Eine Precrash- Sensorik dient zur berührungslosen Erfassung einer Unfallsituation, so daß frühzeitig Fahrzeuginsassenrückhaltesysteme, wie beispielsweise Airbag und Gurtstraffer, aktiviert werden. Dazu kann mittels der horizontalen Auflösung des Abstandssensors 2 die relative Bewegungsbahn eines Objektes bestimmt werden und daraus auf einen gegebenenfalls unvermeidlichen Kollisionsfall geschlossen werden und mittels der vertikalen Auflösung auf einen Überschlag des Kraftfahrzeuges 1 geschlossen werden, was jeweils in der gemeinsamen Auswerteeinheit erfolgt. Die Auswerteeinheit ist dann mit dem Fahrzeuginsassenrückhaltesystemen und/oder einer Zentralverriegelung und/oder einem Notrufsystem und/oder einen Zündsatz für eine Batterieklemme verbunden, so daß auf eine separate Verkabelung zu den anzusteuerbaren Sicherheitskomponenten verzichtet werden kann. Der Abstandssensor 2 dient dabei als umfassender Unfallsensor, aus dessen Signalen die geeigneten Gegenmaßnahmen der verschiedenen Sicherheitsvorkehrungen ableitbar sind.A particularly advantageous embodiment of the invention results when the distance meter 2 is used simultaneously as a pre-crash sensor system. A pre-crash sensor system is used for contactless detection of an accident situation, so that vehicle occupant restraint systems, such as airbag and belt tensioners, are activated at an early stage. For this purpose, the relative movement path of an object can be determined by means of the horizontal resolution of the distance sensor 2 and an inevitable collision case can be inferred therefrom, and an overturn of the motor vehicle 1 can be inferred by the vertical resolution, which takes place in each case in the common evaluation unit. The evaluation unit is then connected to the vehicle occupant restraint systems and / or a central locking system and / or an emergency call system and / or an ignition kit for a battery terminal, so that separate wiring to the controllable safety components can be dispensed with. The distance sensor 2 serves as a comprehensive accident sensor, from whose signals the suitable countermeasures of the various safety precautions can be derived.
