Abstract
Description
Es sind Kollisionswarneinrichtungen für Fahrzeuge auf Basis Ultraschallsensorik oder Infra rotsensorik bekannt und am Markt erhältlich.They are collision warning devices for vehicles based on ultrasonic sensors or infra red sensor technology known and available on the market.
Die bekannten Einrichtungen sind entwickelt worden, um Kollisionen im Nahbereich von Kraftfahrzeugen zu vermeiden.The known devices have been developed for collisions at close range To avoid motor vehicles.
Deshalb kommen Sensoren mit großen Sendekeulen zum Einsatz, um das gesamte Umfeld hinter dem Kraftfahrzeug zu erfassen und bei Unterschreiten eines Mindestabstandes ein Warnsignal auszulösen.That is why sensors with large transmission lobes are used to cover the entire environment to detect behind the motor vehicle and if the distance is less than a minimum Trigger warning signal.
Für LKW ist der Kollisionsfall nicht so wichtig, wichtiger ist die genaue Anzeige des Abstan des zu einer Verladeeinrichtung oder Begrenzung.The case of a collision is not so important for trucks, it is more important to display the exact distance to a loading facility or limit.
Die Distanzanzeige, insbesondere zur genauen Anzeige des Abstandes zu Verladeeinrichtun gen, wird auf einfacher und zu diesem Zweck optimierter Weise gelöst, indem nur ein Ultra schallsensor mit kleiner Sendekeule über einen Mikroprozessor periodisch abgefragt wird, wenn der Rückwärtsgang eines Kraftfahrzeuges eingelegt ist. Eine Software ist so konzipiert, daß bei schneller Fahrt eine Entfernung in grober Auflösung und bei langsamer Fahrt eine feine Auflösung der Entfernung zur Verladeeinrichtung oder zum Hindernis angezeigt wird. Durch eine integrierte Offseteinstellung kann die unterschiedliche Montage des Sensors zur Hinterkante des Fahrzeuges korrigiert werden.The distance display, in particular for the exact display of the distance to loading equipment gen, is solved in a simple and optimized manner for this purpose by using only one Ultra sound sensor with a small transmitting lobe is periodically polled via a microprocessor, when the reverse gear of a motor vehicle is engaged. A software is designed that when driving fast, a distance in rough resolution and when driving slowly, a fine Resolution of the distance to the loading device or to the obstacle is displayed. By An integrated offset setting can be used to mount the sensor differently Rear edge of the vehicle to be corrected.
Kraftfahrzeuge mit Ladebordwänden müssen 2 m vor der Verladeeinrichtung mit sehr geringer Toleranz stehen, wogegen andere Fahrzeuge nur mit ganz geringem Abstand (unter 30 cm, das entspricht unter dem meßbaren Laufzeitunterschied) vor der Verladeeinrichtung halten müssen. Deshalb wird der Distanzsensor mindestens 30 cm vor der Fahrzeughinterkante montiert und durch die Offseteinstellung auf Abstandsanzeige 0 cm korrigiert.Motor vehicles with tail lifts must be 2 m in front of the loading device with very little Tolerance, whereas other vehicles only with a very small distance (less than 30 cm, the corresponds to below the measurable transit time difference) in front of the loading device. Therefore, the distance sensor is installed at least 30 cm in front of the rear edge of the vehicle and corrected by the offset setting on the distance display 0 cm.
