Abstract

In a gritting apparatus (3) for servicing roads in winter, which is mobile or mounted on a gritting vehicle (1), the gritting material is fed, proportional to the driving speed, in meterable amounts to a hydromotor-driven gritting element (7) which rotates about an essentially vertical axis, can be adjusted to different speeds of rotation and gritting widths and is adjustable transversely with respect to the driving direction (arrow 37) in relation to the central longitudinal axis (9) of the gritting apparatus (3) and/or of the gritting vehicle (1) by means of a remote-controlled adjustment drive (22) and whose operating position is indicated by a gritting pattern indicator (28). In order to be able to set the position of the gritting pattern (15) in a manner which is controlled and as precise as possible and to be able to read off this setting exactly, the gritting pattern display takes place by means of an electronic display device in such a way that, in addition to or instead of the set gritting width, in each case the widths of the two gritting pattern sections (15/1, 15/2) lying to the right and left of the central longitudinal axis (9) of the gritting vehicle (1) or of the gritting apparatus (3) are displayed. <IMAGE>

Description

Die Erfindung betrifft ein Winterdienst-Streugerät, das fahrbar oder auf ein Streufahrzeug aufgesetzt ist, bei dem das Streugut mittels eines hydromotorisch fahrgeschwindigkeitsproportional angetriebenen Endlosförderers in dosierbaren Mengen einem hydromotorisch angetriebenen, um eine im wesentlichen vertikale Achse rotierenden und auf unterschiedliche Drehzahlen und Streubreiten einstellbaren Streuorgan zugeführt wird, das in bezug auf die Längsmittelachse des Streugerätes und/oder des Streufahrzeuges quer zur Fahrtrichtung durch einen fernbedienbaren Verstellantrieb verstellbar ist und dessen Arbeitsstellung durch einen Streubildanzeiger angezeigt wird.The invention relates to a winter service spreading device which is mobile or placed on a spreading vehicle in which the spreading material is supplied in metered quantities to a hydromotor-driven spreading member which rotates about a substantially vertical axis and is adjustable to different speeds and spreading widths by means of a hydromotor-driven endless conveyor is, which is adjustable transversely to the direction of travel with respect to the longitudinal center axis of the spreading device and / or the spreading vehicle by a remote-controlled adjustment drive and whose working position is indicated by a scatter pattern indicator.

Bei einem bekannten Winterdienst-Streugerät der gattungsgemäßen Art (DE 19 36 568 C3), das auf der Ladepritsche eines Streufahrzeuges sitzt, ist die Welle des rotierenden, als Streuteller ausgebildeten Streuorgans außerhalb eines vertikalen Fallrohres, durch welches das Streugut auf den Streuteller gelangt, in einem Träger gelagert, der um die Achse des Fallrohres schwenkbar ist. Der Träger ist über ein Untersetzungsgetriebe und eine biegsame Welle von einem drehbaren, im Fahrerhaus des Streufahrzeuges angeordneten Verstellorgan einstellbar. Dabei ist ein mechanischer Streubildanzeiger vorgesehen, der dem Fahrer die jeweilige Stellung des Streutellers anzeigen soll. Der Streubildanzeiger weist eine Sichtscheibe mit der Form eines Kreissektors auf, die mit mehreren streubildähnlichen Markierungen versehen ist. Sie ist in einem Gehäuse um eine Achse schwenkbar gelagert, und wird im selben Untersetzungsverhältnis wie der Träger des Streuorgans vom Verstellorgan verstellt. Die Drehachse dieser Sichtscheibe ist in der Mitte des Gehäuses angeordnet und durch eine Glasscheibe abgedeckt, welche mit Strichen versehen ist, die den Straßenrand und die Straßenmitte markieren.In a known winter service spreader of the generic type (DE 19 36 568 C3) that sits on the loading platform of a spreader vehicle, the shaft of the rotating spreader, designed as a spreader plate, is outside of a vertical downpipe through which the spreader material reaches the spreader plate mounted on a carrier which is pivotable about the axis of the downpipe. The carrier can be adjusted via a reduction gear and a flexible shaft by a rotatable adjusting element arranged in the driver's cab of the spreading vehicle. A mechanical scatter pattern indicator is provided, which is intended to show the driver the respective position of the spreading disc. The scatter pattern indicator has a viewing window with the shape of a circular sector, which is provided with several markings similar to the scatter pattern. It is mounted in a housing so as to be pivotable about an axis, and is adjusted by the adjusting element in the same reduction ratio as the carrier of the scattering element. The axis of rotation of this sight glass is arranged in the middle of the housing and covered by a glass pane which is provided with lines which mark the roadside and the middle of the road.

Abgesehen davon, daß eine solche mechanisch verstellbare Streubildanzeige dem Fahrer höchstens einen groben, ungenauen Anhaltspunkt für die Streubildlage in bezug auf die Längsmittelachse des Fahrzeuges bzw. des Streugerätes vermitteln kann, setzt ihre Anwendung eine mechanische, manuell betätigbare Verstelleinrichtung voraus, welche gleichzeitig mit dem Streuteller auch die Sichtscheibe verschwenkt. Solche mechanischen Verstelleinrichtungen entsprechen aber nicht mehr dem heute verlangten Bedinungskomfort, und überdies ist ihre Einstellgenauigkeit nicht ausreichend für eine möglichst genaue Positionierung des Streubildes, die wiederum Voraussetzung für eine sowohl aus wirtschaftlichen als auch aus Gesichtspunkten des Umweltschutzes möglichst sparsame Ausbringung des Streugutes ist.Apart from the fact that such a mechanically adjustable spreading image display can provide the driver with at most a rough, imprecise reference point for the spreading image position in relation to the longitudinal central axis of the vehicle or the spreading device, its use requires a mechanical, manually actuable adjusting device which works simultaneously with the spreading plate also the viewing window swiveled. However, such mechanical adjustment devices no longer correspond to the level of comfort required today, and moreover their setting accuracy is not sufficient for the most accurate possible positioning of the spreading pattern, which in turn is a prerequisite for economical spreading of the spreading material from both an economic and environmental point of view.

Der Erfindung liegt deshalb die Aufgabe zu Grunde, ein Winterdienst-Streugerät der gattungsgemäßen Art so zu verbessern, daß eine möglichst exakte Positionierung des Streubildes kontrolliert einstellbar und genau ablesbar ist.The invention is therefore based on the object of improving a winter service spreading device of the generic type in such a way that the most exact possible positioning of the spreading pattern can be adjusted in a controlled manner and can be read exactly.

Gelöst wird diese Aufgabe erfindungsgemäß dadurch, daß die Streubildanzeige durch eine elektronische Anzeigevorrichtung in der Weise erfolgt, daß neben oder anstelle der eingestellten Streubreite jeweils die Breiten der beiden rechts und links der Längsmittelachse des Streufahrzeuges bzw. des Streugerätes liegenden Streubildabschnitte angezeigt werden.This object is achieved according to the invention in that the spreading image is displayed by an electronic display device in such a way that, in addition to or instead of the set spreading width, the widths of the two spreading image sections lying to the right and left of the longitudinal central axis of the spreading vehicle or the spreading device are displayed.

Der besondere Vorteil der erfindungsgemäßen Lösung besteht darin, daß der Fahrer des mit einem solchen Winterdienst-Streugerät ausgerüsteten Streufahrzeugs anhand der Streubildanzeige wesentlich genauer als bisher ablesen kann, wie weit das Streuorgan bezogen auf die Längsmittelachse des Fahrzeuges nach links und nach rechts streut. Normalerweise ist dem Fahrer bekannt, wie groß die Gesamtbreite seines Streufahrzeuges ist, so daß er auch genauer abschätzen kann, wie weit das Streubild die Fahrzeugbreite nach beiden Seiten überragt und wie weit das Streubild vom Straßenrand entfernt liegt. Es ist somit eine wesentlich genauere Positionierung des Streubildes auf der zu bestreuenden Verkehrsfläche möglich.The particular advantage of the solution according to the invention is that the driver of the spreading vehicle equipped with such a winter service spreading device can use the spreading image display to read much more accurately than before how far the spreading member spreads to the left and to the right in relation to the longitudinal center axis of the vehicle. Normally, the driver knows how large the total width of his spreading vehicle is, so that he can also estimate more precisely how far the spread pattern extends beyond the vehicle width on both sides and how far the spread pattern is from the roadside. It is therefore possible to position the spreading pattern much more precisely on the traffic area to be spread.

Durch die Ausgestaltung der Erfindung nach Anspruch 2 wird die erfindungsgemäße Lösung insofern verbessert, als nicht nur die Handhabung erleichtert, sondern auch die größtmögliche Genauigkeit in der Übereinstimmung zwischen der wirklichen Streubildlage auf der Verkehrsfläche und der Anzeige gewährleistet wird, wobei die Ausgestaltung nach Anspruch 3 diese Anzeige genau und übersichtlich ablesbar macht.The embodiment of the invention according to claim 2 improves the solution according to the invention in that not only is it easier to use, but also the greatest possible accuracy in the correspondence between the actual scatter pattern on the traffic area and the display is ensured, the embodiment according to claim 3 Makes the display easy to read.

Die Ansprüche 4 bis 7 betreffen Ausgestaltungen der Erfindung, durch welche ein einfacher und funktionssicherer Aufbau sowie eine leichte, übersichtliche Bedienungund insbesondere exakte Einstellung der Parameter ermöglicht wird.Claims 4 to 7 relate to configurations of the invention, by means of which a simple and functionally reliable construction as well as an easy, clear operation and in particular exact setting of the parameters is made possible.

Anhand der Zeichnung wird im folgenden ein Ausführungsbeispiel der Erfindung näher erläutert.An exemplary embodiment of the invention is explained in more detail below with reference to the drawing.

Es zeigt:

  • Fig. 1 in Draufsicht ein Streufahrzeug im Einsatz auf der rechten Fahrbahnhälfte einer zweispurigen Straße;
  • Fig. 2 ein schematisiertes Blockschaltbild der Bedien- und Steuerelemente sowie der Streubildanzeige.
It shows:
  • Figure 1 is a plan view of a gritting vehicle in use on the right half of the lane of a two-lane road.
  • Fig. 2 is a schematic block diagram of the controls and controls and the scatter image.

In Fig. 1 ist ein Streufahrzeug 1 in Draufsicht dargestellt, auf dessen Ladepritsche 2 ein Winterdienst-Streugerät 3 mit einem Streugutbehälter 4 und einer Streuvorrichtung 5 aufgesetzt ist. Die Fahrtrichtung ist durch den Pfeil 37 angegeben. Die Streuvorrichtung 5 weist einen gemäß Pfeil 6 in Uhrzeigerdrehrichtung hydromotorisch angetriebenes Streuorgan 7 in Form eines Streutellers auf, der um eine vertikale Schwenkachse 8, die in der Längsmittelachse 9 des Streufahrzeuges 1 bzw. des Winterdienst-Streugerätes 3 liegt, verschwenkbar und in bezug auf die Längsmittelachse 9 in unterschiedlichen Winkelpositionen (a) fixierbar.In Fig. 1, a spreader vehicle 1 is shown in plan view, on the loading platform 2, a winter service spreader 3 with a grit container 4 and a spreader 5 is placed. The direction of travel is indicated by arrow 37. The spreading device 5 has a spreading member 7, which is driven by a hydraulic motor in the clockwise direction of rotation in the form of a spreading disc, which rotates about a vertical pivot axis 8 lies in the longitudinal central axis 9 of the spreading vehicle 1 or the winter service spreading device 3, can be pivoted and can be fixed in different angular positions (a) with respect to the longitudinal central axis 9.

In einer unten liegenden Förderwanne 10 des Streugutbehälters 4 ist ein Endlosförderer 11 in Form einer Förderschnecke angeordnet, der von einem Hydraulikmotor 12 fahrgeschwindigkeitsproportional angetrieben wird, wobei der Proportionalitätsfaktor zum Einstellen einer bestimmten Streudichte bzw. Streumenge einstellbar ist. Dieser Endlosförderer 11 fördert das Streugut aus dem Streugutbehälter 4 durch ein Förderrohr 13 und ein Fallrohr 14 über eine nicht dargestellte Rutsche punktuell auf das rotierende Streuorgan 7, so daß bei stehendem Fahrzeug beispielsweise das punktierte Streubild 15 und bei fahrendem Fahrzeug der gestrichelt dargestellte Streuteppich 16 entsteht, wenn das Streuorgan 7 um einen Winkel a gegenüber der Längsmittelachse 9 verschwenkt ist.An endless conveyor 11 in the form of a screw conveyor is arranged in a conveying trough 10 of the spreading material container 4, which is driven by a hydraulic motor 12 in proportion to the driving speed, the proportionality factor being adjustable for setting a specific spreading density or spreading quantity. This endless conveyor 11 conveys the grit from the grit container 4 through a conveyor pipe 13 and a down pipe 14 via a slide, not shown, to the rotating spreading member 7, so that, for example, the dotted spread pattern 15 is produced when the vehicle is stationary and the scattered carpet 16 shown in broken lines is produced when the vehicle is moving , when the scattering element 7 is pivoted by an angle a with respect to the longitudinal central axis 9.

Das Streufahrzeug 1 befindet sich in der Mitte der rechten Fahrbahn 17 einer insgesamt 8 m breiten, zweispurigen Straße 18, mit den seitlichen Begrenzungen 19 und 20, deren Mitte durch die Linienmarkierungen 21 dargestellt ist.The gritting vehicle 1 is located in the middle of the right-hand lane 17 of a total of 8 m wide, two-lane road 18, with the lateral boundaries 19 and 20, the center of which is represented by the line markings 21.

Es ist an der am unteren Bildrand angegebenen Meter-Skala erkennbar, daß das Streubild 15 und somit auch der Streuteppich 16 eine Breite von insgesamt 6 m aufweist und in bezug auf die Längsmittelachse 9 so positioniert ist, daß sich ein Streubildabschnitt 15/1 von 2 m Breite rechts von der Längsmittelachse 9 befindet und ein Streubildabschnitt 15/2 links von der Längsmittelachse 9. Des weiteren ist erkennbar, daß das Streubild 15 sich von der vom rechten Straßenrand 20 bis etwa zur Mitte der linken Fahrbahn 17' erstreckt.It can be seen from the meter scale indicated at the bottom of the figure that the scatter pattern 15 and thus also the scatter carpet 16 have a total width of 6 m and is positioned with respect to the longitudinal central axis 9 such that a scatter pattern section 15/1 of FIG. 2 m width is to the right of the longitudinal center axis 9 and a scatter pattern section 15/2 to the left of the longitudinal center axis 9. Furthermore, it can be seen that the scatter pattern 15 extends from the right side of the road 20 to approximately the center of the left lane 17 '.

Zum Verschwenken des Streuorgans 7 um die vertikale Achse 8 ist ein fernsteuerbarer Verstellantrieb 22 vorgesehen, der mit einem Positionsgeber 23 ausgerüstet ist.A remote-controllable adjustment drive 22, which is equipped with a position transmitter 23, is provided for pivoting the spreading member 7 about the vertical axis 8.

Damit der Fahrer des Streufahrzeuges 1 von seinem Fahrerhaus 24 aus alle Parameter eines Streuvorganges einstellen und überwachen kann, ist eine mittels eines Bedienungsaggregates 25 steuerbare bzw. einstellbare Steuer- und Regelungseinrichtung vorgesehen, die in Form eines Blockschaltbildes in Fig. 2 vereinfacht dargestellt ist. Diese Steuer- und Regelungseinrichtung umfaßt einen Steuerungsprozessor 26 mit einer elektronischen Rechnereinheit und einen Regelungsprozessor 27, einen elektronischen Bildschirm 28, den Verstellantrieb 22 zum Einstellen des Streuorgans 7 in bezug auf die Längsmittelachse 9, ein hydraulisches Proportionalventil 29, welches die Drehzahl des das Streuorgan 7 antreibenden Hydraulikmotors 30 regelt und ein Proportionalventil 31, welches die Drehzahl des Hydraulikmotors 12 des Endlosförderers 11 regelt. Der mit LCD oder sonstigen elektronischen Anzeigeelementen versehene Bildschirm 28 weist fünf übereinanderliegende Schriftzeilen auf, in denen die "Streubreite", die "Streumenge", die jeweils befahrene Straße und die "Streubildposition" angezeigt werden. In der untersten Schriftzeile sind durch die vertikalen Striche die Straßenränder 19, 20 und die Längsmittelachse 9 des Streufahrzeuges 1 angedeutet. Außerdem besitzt er eine Menüwählspalte 32, in welcher sich Pfeilmarkierungen befinden, die jeweils anzeigen, welche Menüzeile jeweils gerade aktiviert ist.So that the driver of the spreading vehicle 1 can set and monitor all parameters of a spreading process from his driver's cab 24, a control and regulating device that can be controlled or set by means of an operating unit 25 is provided, which is shown in simplified form in the form of a block diagram in FIG. 2. This open-loop and closed-loop control device comprises a control processor 26 with an electronic computer unit and a control processor 27, an electronic screen 28, the adjustment drive 22 for adjusting the spreading element 7 with respect to the longitudinal central axis 9, a hydraulic proportional valve 29 which determines the speed of the spreading element 7 driving hydraulic motor 30 controls and a proportional valve 31, which controls the speed of the hydraulic motor 12 of the endless conveyor 11. The screen 28 provided with LCD or other electronic display elements has five superimposed lines of text in which the "spreading width", the "spreading quantity", the respective traffic route and the "spreading image position" are displayed. In the bottom line of the text, the vertical lines indicate the road edges 19, 20 and the longitudinal central axis 9 of the spreading vehicle 1. He also has a menu selection column 32, in which there are arrow markings, each of which shows which menu line is currently activated.

Das Bedienungsaggregat 25 weist ein schalthebelartiges Bedienungsorgan 33 auf, das in den angegebenen vier Pfeilrichtungen wahlweise betätigbar ist und Verstellschalter betätigt, wobei durch die Betätigungen nach links und nach rechts die Menüwahl bzw. die Auswahl der zu ändernden Parametern stattfindet, während durch die Betätigungen nach oben oder nach unten jeweils die gewünschte Parametereinstellung erfolgt. Außerdem ist das Bedienungsaggregat 25 mit einem Menüwählschalter 34 und mit einem Eingabeschalter 35 versehen. Mit dem Menüwählschalter 34 wird jeweils das angewählte Menü aktiviert. Mit dem Eingabeschalter 35 werden die jeweils mit dem Bedienungsorgan 33 eingestellten Parameter bestätigt. Das Bedienungsaggregat 25 ist zudem mit einem Disketten- oder Kassettenlaufwerk 36 versehen, mit dem es möglich ist, auf Disketten oder Kassetten geschriebene Programme einzulesen.The control unit 25 has a control lever-like control element 33, which can be optionally operated in the four directions indicated by the arrow and actuates the adjustment switch, the menu selection or the selection of the parameters to be changed taking place by the actuations to the left and to the right, while the actuation means upward or the desired parameter setting is carried out downwards. In addition, the operating unit 25 is provided with a menu selector switch 34 and with an input switch 35. The selected menu is activated with the menu selector switch 34. With the input switch 35, the parameters set in each case with the operating element 33 are confirmed. The operating unit 25 is also provided with a diskette or cassette drive 36, with which it is possible to read programs written on diskettes or cassettes.

Über einen Bildschirmtreiber 36 werden die mit dem Bedienungsaggregat 25 in den Steuerungsprozessor 26 eingegebenen Werte am Bildschirm 28 angezeigt bzw. an den Regelungsprozessor 27 weitergegeben, der über Leistungsverstärker 40, 41 und 42 die jeweils gewünschte Einstellung der beiden Proportionalventile 29 und 31 sowie über den Verstellantrieb 22 die gewünschte Einstellung des Streuorgans 7 in bezug auf die Längsmittelachse 9 bewirkt. Durch den Positonsgeber 23, der beispielsweise aus einem Potentiometer bestehen kann, wird über einen Analog-Digitalwandler 43 dem Regelungsprozessor 27 die jeweilige Winkelposition des Streuorgans 7 in bezug auf die Längsmittelachse 9 gemeldet und an den Steuerungsprozessor weitergegeben. Die Rechnereinheit des Steuerungsprozessors errechnet aus dem eingegebenen Wert der Streubreite, der einer ganz bestimmten Drehzahl des Streuorgans 7 entspricht, und der gemeldeten Position des Streuorgans in bezug auf die Längsmittelachse 9 die Breiten der rechts und links der Längsmittelachse 9 liegenden Streubildabschnitte 15/1 und 15/2 von beispielsweise 2 m und 4 m, und bringt diese, wie in Fig. 2 dargestellt, auf dem Bildschirm 28 in der untersten Zeile in Meterwerten zur Anzeige. Dabei ist es selbstverständlich ohne weiteres möglich, nicht nur ganze Meter anzuzeigen, sondern z.B. auch halbe Meter. Kleinere Bruchteile eines Meters anzuzeigen, wäre angesichts der doch nicht so genau einhaltbaren Streubildgrenzen nicht nur überflüssig, sondern unrealistisch, weil es den Fahrer, der diese angezeigten Werte abliest und sich bei der Steuerung seines Fahrzeuges bzw. bei der Einstellung des Streuorgans 7 in bezug auf die Längsmittelachse 9 zur Annahme verleiten könnte, es handele sich um exakt einhaltbare Werte.Via a screen driver 36, the values entered with the control unit 25 into the control processor 26 are displayed on the screen 28 or passed on to the control processor 27, which uses power amplifiers 40, 41 and 42 to set the respective desired setting of the two proportional valves 29 and 31 and via the adjustment drive 22 causes the desired setting of the scattering element 7 with respect to the longitudinal central axis 9. The position transmitter 23, which can consist, for example, of a potentiometer, reports the respective angular position of the scattering element 7 with respect to the longitudinal central axis 9 to the control processor 27 via an analog-digital converter 43 and passes it on to the control processor. The computer unit of the control processor calculates the width of the scatter pattern sections 15/1 and 15 lying on the right and left of the longitudinal center axis 9 from the entered value of the spreading width, which corresponds to a very specific speed of the spreading member 7, and the reported position of the spreading member with respect to the longitudinal center axis 9 / 2 of, for example, 2 m and 4 m, and, as shown in FIG. 2, displays them on the screen 28 in the bottom line in meter values. It is Of course it is possible to display not only whole meters, but also half meters, for example. Displaying smaller fractions of a meter would not only be superfluous in view of the spreading image limits, which are not so precisely observable, but also unrealistic, because it is the driver who reads these displayed values and is concerned with the control of his vehicle or with the setting of the spreading element 7 the longitudinal central axis 9 could lead to the assumption that the values are precisely observable.

Die elektronischen Bauteile der Steuer- und Bedienungseinrichtung werden in der Regel geschützt im Fahrerhaus 24 untergebracht, wobei das Bedienungsaggregat 25 und der Bildschirm 28 im Fahrerhaus so angeordnet werden, daß sie vom Fahrersitz aus leicht bedienbar bzw. gut ablesbar sind.The electronic components of the control and operating device are usually protected in the cab 24, the control unit 25 and the screen 28 are arranged in the cab so that they are easy to use or read from the driver's seat.

Um einen Streuparameter zu ändern, geht der Fahrer so vor: Zunächst wird der Menüwählschalter 34 betätigt, so daß die zuletzt aktiviert gewesene Pfeilmarkierung in der Menüwählspalte 32 aufleuchtet. Dann wählt er durch entsprechende Betätigung des Bedienungsorgans 33 den zu ändernden Parameter, beispielsweise die "Streubreite" an. Wenn dies geschehen ist, wird der Menüwählschalter 34 wieder betätigt, dann wird durch entsprechende Betätigung des Bedienungsorgans 33 in Richtung der vertikalen Pfeile die andere Streubreite gewählt, die gleichzeitig in der ersten Zeile des Bildschirmes 28 angezeigt wird. Ist der gewünschte Wert auf dem Bildschirm erschienen, so wird dieser Wert durch Betätigung des Eingabeschalters 35 fixiert.In order to change a scattering parameter, the driver proceeds as follows: First, the menu selection switch 34 is actuated so that the arrow marking which was last activated in the menu selection column 32 lights up. He then selects the parameter to be changed, for example the “spreading width”, by actuating the operating member 33 accordingly. When this has happened, the menu selection switch 34 is actuated again, then the other spreading range is selected by corresponding actuation of the operating member 33 in the direction of the vertical arrows, which is simultaneously displayed in the first line of the screen 28. If the desired value has appeared on the screen, this value is fixed by actuating the input switch 35.

Mit der Änderung der Streubreite von beispielsweise 6 m auf 4 m ändert sich automatisch auch die Anzeige der Streubildposition in der untersten Zeile des Bildschirms 28. In diesem Fall würde diese dann lauten: 3 m links von der Längsmittelachse 9 und 1 m rechts von der Längsmittelachse. Das bedeutet dann für den Fahrer, daß er eine entsprechende Verstellung des Streuorgans 7 durch Verkleinerung des Winkels a vornehmen muß und zwar so weit, bis auf beiden Seiten der auch im Bildschirm sichtbaren Längsmittelachse 9 "2 m" erscheinen. Der Fahrer weiß dann, daß nur die rechte Straßenhälfte 17 bestreut wird, wenn er seine Fahrt in der Mitte dieser rechten Straßenhälfte fortsetzt. Die Streumenge läßt sich in analoger Weise auf andere Werte einstellen.When the spreading width changes from 6 m to 4 m, for example, the display of the scatter image position in the bottom line of the screen 28 also changes automatically. In this case, this would then be: 3 m to the left of the longitudinal center axis 9 and 1 m to the right of the longitudinal center axis . This then means for the driver that he has to make a corresponding adjustment of the spreading member 7 by reducing the angle a, and so far until "2 m" appears on both sides of the longitudinal central axis 9 which is also visible on the screen. The driver then knows that only the right half of the road 17 is sprinkled if he continues his journey in the middle of this right half of the road. The spread rate can be set to other values in an analogous manner.

Auf die Anzeige der Streubildposition hat die Änderung des Parameters "Streumenge" jedoch keinen Einfluß. Eine Veränderung dieser Anzeige ergibt sich dadurch nicht.However, changing the "Spread rate" parameter does not affect the display of the spread pattern position. This does not change this display.
