Abstract
Zur Erhöhung des Insassenkomforts bei Geländefahrten, insbesondere bei Fahrten auf einer Böschung, bei der das Fahrzeugsenkrecht zu seiner Längsachse geneigt ist, sieht die Erfindung eine zur Erhöhung des Insassenkomforts ausgebildete Insassenrückhalteeinrichtung vor, die den Insassen in seinem Sitz zurückhält und eingreift, wenn ein definierter Neigungswinkel überschritten wird, der vom Insassen als unangenehm empfunden wird. Der Neigungswinkel liegt unterhalb einem kritischen Neigungswinkel, ab dem ein Überschlagen des Fahrzeugs droht. Die Insassenrückhalteeinrichtung enthält einen Dreipunktsicherheitsgurt, der über einen reversiblen Gurtstraffer angesteuert wird.To increase occupant comfort in off-road driving, especially when driving on a slope where the vehicle is perpendicularly inclined to its longitudinal axis, the invention provides an occupant restraint configured to increase occupant comfort which retains the occupant in his seat and engages when a defined angle of inclination is exceeded, which is perceived by the occupant as unpleasant. The angle of inclination is below a critical angle of inclination, from which a rollover of the vehicle threatens. The occupant restraint device includes a three-point seat belt, which is controlled via a reversible belt tensioner.
Description
Die Erfindung betrifft ein Insassenkomfortsystem nach dem Oberbegriff des Patentanspruchs 1.The invention relates to an occupant comfort system according to the preamble of
Ein derartiges Komfortsystem kann einen allgemein bekannten Sicherheitsgurt beinhalten, der über einen elektromotorischen Gurtstraffer ansteuerbar ist. Elektromotorische Gurtstraffer sind in der Patentliteratur hinlänglich bekannt. Die
Weiterhin ist bekannt, diese reversiblen Gurtstraffer frühzeitig in einer kritischen Fahrsituation und bereits vor dem eigentlichen Unfall auszulösen. Die

Der Erfindung liegt die Aufgabe zugrunde, ein Insassenkomfortsystem, insbesondere ein Insassenrückhaltesystem, zur Erhöhung des Insassenkomforts weiter zu verbessern. Die erfindungsgemäße Lösung dieser Aufgabe besteht in den Merkmalen des Anspruchs 1, vorteilhafte Ausgestaltungen der Erfindung beschreiben die Unteransprüche.The object of the invention is to further improve an occupant comfort system, in particular an occupant restraint system, for increasing occupant comfort. The achievement of this object is the features of
Die Auslösung des Insassenkomfortsystems zur Rückhaltung des Insassen in seiner Position erfolgt oberhalb eines Schwellwertes, ab der der Insasse die Position als unangenehm empfindet. Üblicherweise sitzt der Insasse im Fahrzeug und wird durch einen Rückhalteeinrichtung gesichert. Die Rückhalteeinrichtung ist normalerweise als Sicherheitsgurt ausgebildet, sie kann aber auch durch einen in der
Üblicherweise empfindet der Insasse seine Position dann als unkomfortabel, wenn er zusätzliche Kräfte aufwenden muss, um seine aktuelle Position beizubehalten. Um nicht aus seiner derzeitigen Position verlagert zu werden, muss der Insasse aktiv weitere Muskeln anspannen. Die Insassenposition wird also dann als unangenehm empfunden, wenn Verlagerungskräfte ein für den Insassen bekanntes Maß im normalen Fahrbetrieb übersteigen und der Insasse erhöhte Muskelkräfte aufwenden muss.Typically, the occupant then finds his position uncomfortable when he has to expend additional forces to maintain his current position. In order not to be relocated from its present position, the occupant must actively harness more muscle. The occupant position is therefore perceived as unpleasant when displacement forces exceed a known for the occupant measure in normal driving and the occupant must spend increased muscle forces.
Die Auslösung des Insassenkomfortsystems erfolgt unterhalb eines Schwellwertes bei dem üblicherweise Insassenrückhalteeinrichtungen ausgelöst werden. Diese werden bei einem drohenden Unfall oder bei kritischen Fährsituationen über Precrash-Sensoren oder entsprechende Systeme ausgelöst. Darunter sollen z. B. Radarsysteme, elektronische Stabilitätssysteme oder Fahrzeug-Fahrzeug-Kommunikationssysteme verstanden werden.The release of the occupant comfort system takes place below a threshold at which usually occupant restraint devices are triggered. These are triggered by pre-crash sensors or corresponding systems in the event of an imminent accident or critical ferry situations. Including z. As radar systems, electronic stability systems or vehicle-vehicle communication systems are understood.
Die Auslösung des Komfortsystems erfolgt demgemäß innerhalb eines Auslösefensters, dessen unterer Schwellwert durch das Komfortempfinden des Insassen und dessen oberer Schwellwert durch das Erreichen einer kritischen Fahrsituation definiert ist. Nach Erreichen der kritischen Fahrsituation kann die Steuerung der Insassenrückhalteeinrichtung von einer Sicherheitssystemsteuerung übernommen werden.The triggering of the comfort system is accordingly within a trip window whose lower threshold is defined by the comfort of the occupant and its upper threshold value by reaching a critical driving situation. After reaching the critical driving situation, the control of the occupant restraint device can be taken over by a safety system control.
In der dargestellten Rückhalteeinrichtung zur Erhöhung des Insassenkomforts wird der Insasse schon vor der beginnenden Verlagerung sanft in seinem Sitz zurückgehalten.In the illustrated restraint to increase occupant comfort, the occupant becomes gently restrained in his seat even before the beginning shift.
In einer weiterführenden Ausführungsform kann das Ansteuern des Komfortsystems in Abhängigkeit der Fahrzeugneigung senkrecht zu dessen Fahrzeuglängsachse erfolgen. Dabei löst ein Sensor zur Erfassung der Fahrzeugneigung nach Überschreiten eines Schwellwerts das als Insassenrückhalteeinrichung ausgebildete Insassenkomfortsystem aus. Eine solcher Sensor zur Neigungsdetektierung ist z. B. aus der
In einer weiteren vorteilhaften Variante wird das Rückhaltesystem bei Überfahren einer holprigen Wegstecke ausgelöst, bei der das Fahrzeug stark erschüttert wird und zu Pendelbewegungen neigt. Der Insasse wird durch die Rückhalteeinrichtung an dem Sitz angebunden und daran gehindert eigene Pendelbewegungen relativ zum Fahrzeug auszuführen. Die Auslösung der Rückhalteeinrichtung kann durch Auswertung von Informationen zum Verhalten des Fahrwerks erfolgen, z. B. kann die Richtungsänderungsgeschwindigkeit der Dämpferbewegung erfasst werden.In a further advantageous variant, the restraint system is triggered when driving over a bumpy path, in which the vehicle is greatly shaken and tends to pendulum movements. The occupant is tethered to the seat by the retainer and prevented from performing its own oscillations relative to the vehicle. The triggering of the retaining device can be done by evaluating information about the behavior of the chassis, z. B. the direction change rate of the damper movement can be detected.
Gemäß einer weiteren Ausführungsform erfolgt die Ansteuerung der Rückhalteeinrichtung in Abhängigkeit von einer Sitzbelegungserkennung eines Insassen. Dies kann über Drucksensoren im Sitzpolster erfolgen. Bei einem Sicherheitsgurt als Rückhalteeinrichtung kann dies auch über eine Abfrage erfolgen, ob der Gurt angelegt ist.According to a further embodiment, the activation of the restraint device takes place as a function of a seat occupancy recognition of an occupant. This can be done via pressure sensors in the seat cushion. With a safety belt as a restraint device, this can also be done via a query whether the belt is applied.
Die Rückhalteeinrichtung ist als ein durch den Insassen zu- oder abschaltbares System ausgeführt und/oder der untere Auslöseschwellwert ist einstellbar ausgeführt, so dass der Insasse diesen seinem individuellen Komfortempfinden und seinem Einsatzbedarf anpassen kann und/oder der Insasse somit die Möglichkeit hat dieses System beim Betreibendes Fahrzeuges in einer Stadt auszuschalten. Bei einer Fahrt im Gelände mit Böschungsfahrten kann das System zugeschaltet werden.The restraint device is embodied as a system which can be switched on or off by the occupant and / or the lower triggering threshold is adjustable, so that the occupant can adapt this to his or her individual sense of comfort and use and / or the occupant thus has the option of operating the system Turn off vehicle in a city. When driving off-road with embankment drives, the system can be switched on.
In einer weiteren bevorzugten Ausführungsform kann der Insasse die Rückhaltekräfte individuell einstellen, da ein angenehmes Empfinden bezüglich der Stärke der Rückhaltekraft von Insassen unterschiedlich bewertet wird. Die Einstellung kann über eine Variation des Drehmoments erfolgen, das ein Elektromotor zum Aufwickeln der Gurttrommel aufbringt.In a further preferred embodiment, the occupant can adjust the restraining forces individually, since a pleasant sensation regarding the strength of the restraining force is assessed differently by occupants. The adjustment can be made via a variation of the torque applied by an electric motor for winding the belt drum.
Weiterhin kann vorgesehen sein, dass die Rückhaltekräfte bei stärker werdenden äußeren Einflüssen ansteigen. Bei einer Böschungsfahrt kann bei zunehmender Neigung die Gurtkraft erhöht werden oder seitliche Polster können bei erhöhten Rüttelbewegungen weiter ausgefahren werden.Furthermore, it can be provided that the retention forces increase with increasing external influences. In a slope drive, the belt force can be increased with increasing inclination or side pads can be extended with increased shaking movements on.
Anhand der Zeichnung wird ein Ausführungsbeispiel der Erfindung näher erläutert. Dabei zeigen:Reference to the drawings, an embodiment of the invention will be explained in more detail. Showing:
Der Sicherheitsgurt
Ein Einsatz des Insassenkomfortsystems
Ergänzend oder alternativ zu reversiblen Gurtstraffern können auch reversibel aufblasbare Sitzpolster als Insassenschutzmittel verwendet werden. Die Funktion der Stellmittel wäre dann beispielsweise Gebläsen oder druckbefüllbaren Patronen zugewiesen.In addition or as an alternative to reversible belt tensioners, reversibly inflatable seat cushions can also be used as occupant protection means. The function of the actuating means would then be assigned, for example, blowers or pressure-fillable cartridges.
