Vorrichtung zur Überwachung des Abstands wenigstens eines Bezugspunktes an einem Fahrzeug relativ zur Fahrbahn ■ -Device for monitoring the distance of at least one reference point on a vehicle relative to the roadway ■ -
Stand der TechnikState of the art
Die Erfindung geht aus von einer Vorrichtung nach der Gattung des Hauptanspruchs. Zur Reifendrucküberwachung eines Fahrzeugs ist es z.B. aus der DE-OS 28 32 UUT bekannt, den Luftdruck durch einen an der Innenseite einer Felge angebrachten Drucksensor zu erfassen und dessen Meßwert berührungslos auf einen ortsfest an der Karosserie angebrachten Aufnehmer zu übertragen. Eine solche Anordnung ist zum einen sehr aufwendig und bedarf sowohl eines mechanischen Eingriffs an den Felgen, wie auch einer komplizierten Justierung von Geber und Aufnehmer. Da diese komplizierte Anordnung zudem stark mit dem Fahrbahnschmutz in Berührung kommt, ist eine Störanfälligkeit nicht zu vermeiden. Ein falscher Luftdruck beeinträchtigt nicht nur die Fahrsicherheit des Fahrzeugs, sondern verändert darüber hinaus die Neigung der Fahrzeugkarosserie sowie deren Abstand zur Fahrbahn, wasThe invention is based on a device according to the preamble of the main claim. For tire pressure monitoring of a Vehicle it is known e.g. from DE-OS 28 32 UUT, to detect the air pressure by a pressure sensor attached to the inside of a rim and its measured value to be transferred contactlessly to a sensor that is fixedly attached to the body. Such an arrangement is on the one hand very complex and requires both a mechanical intervention on the rims, as well as a complicated adjustment of encoder and transducer. Since this complicated arrangement is also strongly affected by the dirt from the road comes into contact, a susceptibility to failure cannot be avoided. Incorrect air pressure affects not only the driving safety of the vehicle, but also changes the inclination of the vehicle body as well as their distance to the road, what
sich z.B. für die Scheinwerfereinstellung ungünstig auswirkt.has an unfavorable effect, for example, on the headlight setting.
Um die Lage der Scheinwerfer bezüglich einer veränderten Karosserieneigung zu kompensieren, ist es beispielsweise aus der US-PS 36 3^ 677 bekannt, mittels eines induktiven Weggebers den Abstand zwischen der Karosserie und der Radaufhängung eines Fahrzeugs zu messen, aus der Differenz der Abstände an den beiden Fahrzeugachsen die Neigung zu bestimmen und entsprechend den Scheinwerferwinkel zu korrigieren. Diese Anordnung hat den Nachteil, daß ein falscher Luftdruck nicht miterfaßt werden kann und als Fehler in die Scheinwerfereinstellung eingeht. Darüber hinaus ist auch diese Anordnung wegen der komplizierten Erfassung der Fahrzeugneigung aufwendig und teuer.To compensate for the position of the headlights with respect to a changed body inclination, it is for example known from US-PS 36 3 ^ 677, by means of an inductive Weggebers to measure the distance between the body and the suspension of a vehicle from the Difference in the distances on the two vehicle axles to determine the inclination and, accordingly, the headlight angle to correct. This arrangement has the disadvantage that incorrect air pressure cannot be detected and is included as an error in the headlight setting. In addition, this arrangement is also complicated because of the Detecting the vehicle inclination is complex and expensive.
Zur Abstandsmessung zwischen Kraftfahrzeugen, insbesondere zur Erleichterung des Einparkens sind weiterhin aus der DE-OS 2 312 2U8, der DE-OS 2 531 665, der AT-PS 2^8 891+ sowie der DE-OS 32 07 950 berührungslose Abstandsmeßvorrichtungen bekannt, die insbesondere nach dem Ultraschall- oder Infrarot-Prinzip arbeiten. Eine Messung des Abstands zur Fahrbahn ist dort jedoch nicht erforderlich und daher auch nicht angesprochen.For distance measurement between motor vehicles, in particular to facilitate parking, DE-OS 2 312 2U8, DE-OS 2 531 665, AT-PS 2 ^ 8 89 1 + and DE-OS 32 07 950 contactless distance measuring devices are known that work in particular on the ultrasonic or infrared principle. A measurement of the distance to the roadway is not required there and is therefore not addressed.

Die Erfassung der Karosserieneigung kann dabei in vorteilhafter Weise über eine Niveauregelvorrichtung zur Kompensation der ScheinwerfereinstellungThe device according to the invention with the characteristic Features of the main claim has the advantage of a simple, non-contact distance measurement to the roadway safe and inexpensive monitoring of the air pressure of the vehicle tires and / or the body inclination guarantee. The body inclination can advantageously be detected using a level control device to compensate for the headlight setting
und/oder der Karosserieneigung selbst dienen. Dabei wird ein falscher Luftdruck automatisch mit berücksichtigt. Die Anbringung der Abstandsmeßvorrichtung bzw. -vorrichtungen ist auch noch bei Nachrüstung sehr einfach, und eine Justie rung kann entfallen.and / or serve the body inclination itself. It will an incorrect air pressure is automatically taken into account. the Attachment of the distance measuring device or devices is very simple even when retrofitting, and an adjustment tion can be omitted.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen .!er im Hauptanspruch angegebenen Vorrichtung möglich.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Das einzige Ausführungsbeispiel zeigt die Anbringung von Abstandsmeßvorrichtungen an einem Fahrzeug sowie eine Auswerteschaltung im Blockschaltbild. An embodiment of the invention is shown in the drawing shown and explained in more detail in the following description. The only embodiment shows the attachment of distance measuring devices to a vehicle and an evaluation circuit in the block diagram.
Beschreibung des AusführungsbeispielsDescription of the embodiment
Die Räder 10, 11 eines Kraftfahrzeugs 12 stehen auf einer Fahrbahn 13. Im vorderen Bereich 1U der Karosserie ist eine berührungslose Abstandsvorrichtung 15 und im hinteren Teil 16 der Karosserie eine berührungslose Abstandsmeßvorrichtung 17 befestigt. Die Abstandssignale A und BThe wheels 10, 11 of a motor vehicle 12 are on a Lane 13. In the front area 1U of the body is a contactless distance device 15 and in the rear part 16 of the body a contactless distance measuring device 17 attached. The distance signals A and B
■ν■ ν
der Abstandsmeßvorrichtungen 15, 17 sind einer Differen: bildungsstufe 18 zugeführt, deren Ausgangssignal A-B über einen Steuersignalgenerator 19 ein Stellglied 20 steuert, durch das die Winkelstellung der Fahrzeugscheinwerfer 21 einstellbar sind.of the distance measuring devices 15, 17 are one of the differences: education stage 18 supplied, the output signal A-B An actuator 20 via a control signal generator 19 controls by which the angular position of the vehicle headlights 21 are adjustable.
Ebenso ist an der vorderen Radaufhängung 22 eine berührungslose Abstandsmeßvorrichtung 23 sowie an der hinteren Radaufhängung 2U eine berührungslose Abstandsmeßvorrichtung 25 befestigt. Die Signale dieser Abstandsmeßvorrichtung 23, 25 sind einer Schwellwert stufe 26 zugeführt, durch die Kontrolleuchten 27, 28 sowie ein Warntongeber 29 steuerbar ist.Likewise, on the front wheel suspension 22 there is a contactless one Distance measuring device 23 and a contactless distance measuring device on the rear wheel suspension 2U 25 attached. The signals of this distance measuring device 23, 25 are fed to a threshold value stage 26, can be controlled by the control lights 27, 28 and a warning sounder 29.
Die Wirkungsweise der Scheinwerfer-Niveauregulierung besteht darin, daß durch die beiden Abstandsmeßvorrichtungen 15, 17 der jeweilige Abstand zur Fahrbahn 13, gemessen wird. Diese berührungslose Abstandsmessung ist im eingangs angegebenen Stand der Technik näher dargestellt und beruht prinzipiell auf der Laufzeitmessung eines Signals bzw. einer Welle von der Abstandsmeßvorrichtung 15 zur Fahrbahn 13 und zurück. Zur Messung können dazu prinzipiell Ultraschall-, Infrarot-, Radar- oder sonstige elektromagnetische Wellen verwendet werden. Die Abstandsmeßvorrichtung besteht somit prinzipiell aus einem Sender und einem Smpfänger. Eine hier nicht näher dargestellte elektronische Auswerteschaltung wandelt diese Laufzeit gemäß dem eingangs angegebenen Stand der Technik in ein abstandsabhängiges elektrisches Signal um. Bei unbelastetem Fahrzeug, korrektem Reifendruck sowie gleich hohen Befestigungsorten, müßten die Signale A und B der beiden Abstandsmeßvorrichtungen 15 und 17 identisch sein, so daß die Differenzierbildungsstufe 18 kein Ausgangssignal erzeugt. Ergibt sich infolge Belastung, AlterungThe headlight level control works in that the respective distance from the roadway 13 is measured by the two distance measuring devices 15, 17 will. This contactless distance measurement is shown in more detail in the prior art mentioned at the beginning and is based in principle on the transit time measurement of a signal or a wave from the distance measuring device 15 to lane 13 and back. In principle, ultrasound, infrared, radar or other can be used for measurement electromagnetic waves are used. The distance measuring device therefore basically consists of a transmitter and a receiver. An electronic evaluation circuit, not shown here, converts this transit time into a distance-dependent electrical signal according to the prior art mentioned at the beginning. With unencumbered Vehicle, correct tire pressure and equally high mounting locations, signals A and B should be the two distance measuring devices 15 and 17 must be identical, so that the differentiating stage 18 has no output signal generated. Occurs as a result of exposure to aging

von Federn, falschem Luftdruck oder sonstigen Einflüssen eine Veränderung der Karosserieneigung, so entsteht am Ausgang der Differenzbildungsstufe 18 ein entsprechendes Signal, das im Steuersignalgenerator 19 in ein entsprechendes Steuersignal für die Stellvorrichtung 20 umgewandelt wird. Diese Stellvorrichtung korrigiert entsprechend der Karosserieneigung die Winkelstellung der Scheinwerfer 21. Auf diese Weise wird eine zu schlechte Ausleuchtung der Fahrbahn bzw. eine Blendung der entgegenkommenden Fahrzeuge wirksam verhindert.from springs, incorrect air pressure or other influences a change in the body inclination occurs on Output of the difference formation stage 18 a corresponding Signal that is converted in the control signal generator 19 into a corresponding control signal for the actuating device 20 will. This adjusting device corrects the angular position of the headlights in accordance with the body inclination 21. In this way, the illumination of the road is too poor or the oncoming road is dazzled Vehicles effectively prevented.
Entsprechend wird der Abstand der Abstandsmeßvorrichtungen 23, 25 bzw. der Radaufhängungen 22, 2h zur Fahrbahn 13 gemessen, um den Luftdruck der Reifen zu kontrollieren. Bei sinkendem Luftdruck verringert sich dieser Abstand. Ab einem gewissen minimalen Grenzabstand wird ein kritischer Wert des Luftdrucks erkannt und optisch und/oder akustisch angezeigt. Entsprechend diesem kritischen Abstand ist der Schwellwert der Schwellwertstufe 26 gewählt. Wird dieser Schwellwert unterschritten, so leuchtet die entsprechende Kontrolleuchte 27 bzw. 28 auf. Alternativ oder zusätzlich kann ein akustisches Warnsignal durch den Warntongeber 29 erzeugt werden.Correspondingly, the distance of the distance measuring devices 23, 25 or the wheel suspensions 22, 2h to the roadway 13 is measured in order to control the air pressure of the tires. This distance decreases as the air pressure drops. Above a certain minimum limit distance, a critical value of the air pressure is recognized and indicated optically and / or acoustically. The threshold value of the threshold value stage 26 is selected in accordance with this critical distance. If the value falls below this threshold, the corresponding control lamp 27 or 28 lights up. Alternatively or additionally, an acoustic warning signal can be generated by the warning sounder 29.
Anstelle der dargestellten Anordnung mit zwei Abstandsmeßvorrichtungen 23, 25 kann auch jedem Rad eine solche Abstandsmeßvorrichtung zugeordnet werden, so daß der Luftdruck jedes Reifens getrennt kontrollierbar ist.Instead of the arrangement shown with two distance measuring devices 23, 25 such a distance measuring device can also be assigned to each wheel, so that the The air pressure of each tire can be controlled separately.
Es sei noch festgehalten, daß die Erfindung nicht auf die dargestellten Ausführungsbeispiele beschränkt ist. So kann beispielsweise in Abhängigkeit des gemessenen Abstandes anstelle der Scheinwerfer die gesamte Karosserie wieder in eine Normlage geregelt werden. Dies kann beispielsweise durch eine Druckvariierung eines hydraulischen Federsystems oder durch Druckzuführung in denIt should be noted that the invention does not apply to the illustrated embodiments is limited. So For example, depending on the measured distance, the entire body can be used instead of the headlights be regulated again in a standard position. This can be done, for example, by varying the pressure of a hydraulic Spring system or by applying pressure to the
