Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung mit den Merkmalen des Oberbegriffs von Patentanspruch 1.The invention relates to a device with the features of the preamble of claim 1.
Derartige Vorrichtungen dienen zum Anzeigen einer Gefahr, die durch ein in der Nachbarspur befindliches Objekt hervorgerufen wird. Es ist bekannt, auf eine mög liche Gefahr akustisch hinzuweisen (WO 94/04941). Auch ist es bekannt, diese Ge fahr optisch zu signalisieren (US 5,786,772). Dabei wird im Außenspiegel und ggf. sogar im Innenspiegel ein Lichtsignal aktiviert. Beide bekannten Vorrichtungen ber gen die Gefahr in sich, übersehen bzw. überhört zu werden. Dies ist angesichts der zunehmenden Belastung des Fahrers durch die zunehmende Verkehrsdichte in steigendem Maße der Fall. Damit aber wird die Wirkung der bekannten Vorrichtun gen ins Gegenteil verkehrt. Einerseits verläßt sich der Fahrer auf die Existenz der Warnung und glaubt, daß eine Gefahr nicht besteht, während die Warnung lediglich untergegangen ist. Ein weiterer Nachteil optischer oder akustischer Verfahren ist deren Wahrnehmbarkeit durch evtl. weitere Fahrzeuginsassen.Such devices are used to indicate a danger caused by a in the Neighboring track object is caused. It is known to be possible acoustic danger (WO 94/04941). It is also known this Ge visually signal driving (US 5,786,772). In the exterior mirror and if necessary even a light signal is activated in the interior mirror. Both known devices ber there is a risk of being overlooked or ignored. This is in the face of increasing driver stress from increasing traffic density in increasingly the case. But this is the effect of the known device the opposite. On the one hand, the driver relies on the existence of the Warning and believes that there is no danger as the warning merely has perished. Another disadvantage of optical or acoustic methods is their perceptibility by any other vehicle occupants.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, bei der die Gefahr der Nicht-Wahrnehmung deutlich reduziert ist und deren Aktivität allein dem Fahrer bemerkbar ist.The invention has for its object a device of the aforementioned To create a way in which the risk of not being perceived is significantly reduced and whose activity is only noticeable to the driver.
Die Erfindung löst diese Aufgabe mit den Merkmalen des Patentanspruchs 1. The invention solves this problem with the features of claim 1.
Durch die Änderung der Bediencharakteristik des Betätigungsglieds erfährt der Fah rer selbsttätig und beim Benutzen des Betätigungsglieds auf haptische Weise, daß der beabsichtigte Spurwechsel durch ein nahes oder sich schnell näherndes Objekt gefährlich sein kann. Voraussetzung dafür ist lediglich, daß er tatsächlich das Betätigungsglied bedient. Abgesehen davon, daß er hierzu aufgrund gesetzlicher Bestimmungen verpflichtet ist, wird er durch die Erfindung geradezu angeregt, sich gesetzeskonform zu verhalten. Über das Betätigungsglied erhält er auf einfache Weise signalisiert, ob er tatsächlich ohne eine Unfallgefahr einen Spurwechsel vornehmen kann. Dies wird seine Bereitschaft, diese Absicht anzuzeigen, deutlich erhöhen.The driver learns from the change in the operating characteristics of the actuator rer automatically and when using the actuator in a haptic way that the intended lane change through a nearby or rapidly approaching object can be dangerous. The only requirement is that he actually does that Actuator operated. Apart from the fact that he did this on the basis of legal Provisions, he is almost stimulated by the invention himself behave in accordance with the law. Via the actuator, he receives on simple Weise signals whether he is actually changing lanes without the risk of an accident can make. This shows his willingness to indicate this intention increase.
Es ist prinzipiell möglich, die Bediencharakteristik des Betätigungsglieds immer dann zu verändern, wenn sich ein Objekt im toten Winkel befindet. Demgegenüber ergibt sich eine Verbesserung, wenn diese Veränderung nur dann vorgenommen wird, wenn das Objekt zumindest die gleiche Geschwindigkeit wie die Eigengeschwindig keit des Fahrzeugs aufweist. Liegt die Geschwindigkeit des Objekts jedoch unter der Fahrzeuggeschwindigkeit, so besteht eine Kollisionsgefahr allenfalls dann, wenn sich das Objekt im unmittelbaren Nahbereich des Fahrzeugs befindet. Da die Be stimmung der Objektgeschwindigkeit einhergeht mit einer Abstandsbestimmung, kann durch einen entsprechenden Filter auf einfache Weise unterschieden werden, wenn sich das Objekt außerhalb des Nahbereichs befindet. In diesem Fall wird die Betätigungscharakteristik nur dann verändert, wenn sich das Objekt so schnell nähert, daß bei einem Spurwechsel Kollisionsgefahr besteht.In principle, it is always possible to operate the actuator to change when an object is in the blind spot. In contrast results an improvement if this change is only made if the object is at least the same speed as its own speed speed of the vehicle. However, the speed of the object is less than that Vehicle speed, there is a risk of collision at most if the object is in the immediate vicinity of the vehicle. Since the Be adjustment of the object speed goes hand in hand with a distance determination, can be easily distinguished by an appropriate filter, when the object is out of close range. In this case the The actuation characteristics only change if the object moves so quickly approaches that there is a risk of collision when changing lanes.
Auch die Art und Weise, auf die die Bediencharakteristik verändert wird, läßt ver schiedene Variationsmöglichkeiten zu. Zwei Möglichkeiten sind in den Patent ansprüchen 3 und 4 angegeben. Mit den Merkmalen des Patentanspruchs 2 ist auch die Möglichkeit umfaßt, bei der das Betätigen des Betätigungsglieds ggf. überhaupt nicht mehr möglich ist. Der Fahrer erhält auf diese Weise deutlich und "unübersehbar" signalisiert, daß ein Spurwechsel nicht angezeigt ist. The way in which the operating characteristics are changed leaves ver different possible variations. Two options are in the patent claims 3 and 4 specified. With the features of claim 2 is also includes the possibility of actuating the actuator at all is no longer possible. The driver gets this clear and "Visible" signals that a lane change is not indicated.
Die Merkmale des Patentanspruchs 4 beinhalten auch die Möglichkeit, die Vibration unterschiedlich entsprechend der Schwere der bestehenden Gefahr zu gestalten. Ein Parameter hierfür kann die Differenzgeschwindigkeit zwischen dem Objekt und dem eigenen Fahrzeug selbst sein. Ist diese Differenzgeschwindigkeit groß, so han delt es sich beim Objekt um ein überholendes Fahrzeug mit einer großen Kollisions gefahr. Ist die Differenzgeschwindigkeit beispielsweise 0, so kann ein Spurwechsel vorgenommen werden, sofern sich das Objekt außerhalb des unmittelbaren Nah bereichs befindet.The features of claim 4 also include the possibility of vibration different depending on the severity of the existing danger. A parameter for this can be the difference in speed between the object and be your own vehicle. If this differential speed is high, then han the object is an overtaking vehicle with a large collision danger. If the differential speed is 0, for example, a lane change can be made be made provided the object is outside the immediate vicinity area.
Auf diese Weise wird es mit einfachen Mitteln möglich, die beim Spurwechsel durch insbesondere im toten Winkel befindliche Fahrzeuge bestehende Unfallgefahr deutlich zu verringern.In this way it becomes possible with simple means that by changing lanes vehicles in particular in the blind spot present an accident risk decrease significantly.
