Abstract
Description
Diese Erfindung betrifft eine Sensoreinrichtung für ein System zur Hinderniserfassung, und insbesondere eine Sensoreinrichtung, die einen kegelförmigen Wellenleiter aufweist, womit das Streusignal in einem Aufspürbereich konzentriert wird, wodurch die Sensoren besser eine Signalreflexion aufspüren und darauf reagieren können.These The invention relates to a sensor device for an obstacle detection system, and in particular a sensor device comprising a conical waveguide has, with which the scatter signal is concentrated in a detection area, whereby the sensors better detect a signal reflection and can react to it.
Heutzutage ist ein übliches Hindernis-Erfassungs-System ganz populär in Limousinen und anderen Typen von Fahrzeugen eingebaut, wobei Ultraschallsensoren in den vorderen und hinteren Stoßfängern angebracht sind. Wenn Sensoren zum Rückwärtsfahren in gewöhnliche Limousinen eingebaut werden, ist eines ihrer Hauptprobleme die Genauigkeit beim Aufspüren und der Entfernungsmessung von Gegenständen. Fehlerhafte Auslösung der Alarme von Rückfahrsensoren liegt häufig eher an unangemessener Konstruktion der Steuerschaltungen statt an einer Störung durch die Umgebung.nowadays is a common one Obstacle Detection System quite popular in sedans and others Types of vehicles installed, with ultrasonic sensors in the attached to front and rear bumpers are. If sensors for reversing in ordinary Limousines are installed, one of their main problems is the accuracy when tracking down and the distance measurement of objects. Faulty release of the Alarms from reversing sensors is common rather, due to inappropriate design of the control circuits at a fault through the environment.
Gewöhnliche
Sensoren können

kein Hindernis vorhanden ist. Unter Bezug auf die
Bei vielen Fahrzeugen mit Vierradantrieb, wie Geländewagen, Freizeitwagen und anderen schweren Fahrzeugen ist die Gesamtlänge dieser Art von Fahrzeugen häufig ein Vielfaches derjenigen einer Limousine, so dass sich der Fahrzeugführer in dem Vordersitz auf elektronische Sensoren, welche die Umgebungsbedingungen um das Fahrzeug aufnehmen, verlassen muss. Diese Art von Fahrzeugen haben gewöhnlich beiderseits der vorderen und hinteren Stoßfänger zusätzlich elektronische Sensoren installiert, die dazu neigen, eine beträchtliche Menge an Störecho zu erzeugen. Unter solchen Umständen nehmen Sensoren häufig falsche Signale auf und lösen den Alarm aus, obwohl tatsächlich kein Hindernis hinter dem Fahrzeug existiert. Diese falschen Alarme von den Sensoren zur Unterstützung sind sehr störend für Fahrzeugfahrer. Diese und andere Probleme können vermieden werden, wenn in den Sensor zum Rückwärtsfahren in die Arbeitsabläufe zur Aufspürung und Entfernungsmessung von Gegenständen eine dynamische Anpassung von Kenngrößen zur Umgebungskontrolle eingebaut ist, um das Streusignal in einem Aufspürbereich zu konzentrieren und auf diese Weise die gesamte Systemgenauigkeit zu erhöhen.at many four-wheel drive vehicles, such as SUVs, recreational vehicles and Other heavy vehicles is the overall length of this type of vehicle often a multiple of those of a sedan, so that the driver in the Front seat on electronic sensors, which the environmental conditions to pick up the vehicle, leave. This type of vehicles have usually installed electronic sensors on both sides of the front and rear bumpers, which tend to be a considerable one Amount of false echoes to create. In such circumstances take Sensors frequently Incorrect signals and release the alarm off, though actually no obstacle behind the vehicle exists. These false alarms from the sensors for support are very disturbing for vehicle drivers. These and other problems can be avoided when in the sensor for reversing in the work processes for revealing and distance measurement of objects a dynamic adjustment of environmental control parameters is installed to concentrate the scatter signal in a tracking area and in this way to increase the overall system accuracy.
Das Hauptziel der gegenwärtigen Erfindung ist, ein Verfahren und ein Gerät zur Aufspürung und Entfernungsmessung von Gegenständen mit hoher Genauigkeit bereitzustellen, indem ein technisches Mittel eingebaut wird, das während des Vorgangs der Aufspürung und Entfernungsmessung von Gegenständen die Kenngrößen zur Umgebungskontrolle dynamisch anpassen kann.The Main objective of the current The invention is a method and apparatus for tracing and ranging of objects to provide high accuracy by a technical means is installed during the the process of detection and distance measurement of objects the characteristics for Can dynamically adjust environment control.
