Description

Die vorliegende Erfindung betrifft ein Winterdienstfahrzeug mit einem Streugerät zum Ausbringen von Streustoff, wobei das Streugerät einen Streustoff-Vorratsbehälter, eine Ausbringeinrichtung mit einem rotierend angetriebenen Streuteller, eine die Ausbringeinrichtung beschickende Fördereinrichtung und eine Steuereinrichtung umfaßt, welche die Stellung der Ausbringeinrichtung und die Streutellerdrehzahl einerseits in Abhängigkeit von einer vorgegebenen Streubildlage und andererseits in Abhängigkeit von der Fahrgeschwindigkeit und/oder dem Streustoffdurchsatz steuert, wozu eine Speichereinheit zum Abspeichern von auf die Fahrgeschwindigkeit und/oder den Streustoffdurchsatz bezogenen Einstellwerten für die Stellung der Ausbringeinrichtung und/oder die Streutellerdrehzahl sowie von für die Abhängigkeit der Stellung der Ausbringeinrichtung und/oder die Streutellerdrehzahl von der Fahrgeschwindigkeit und/oder dem Streustoffdurchsatz charakteristischen Zusammenhängen vorgesehen ist.The present invention relates to a winter utility vehicle with a spreader for spreading spreading material, wherein the spreader comprises a spreading material reservoir, a dispensing device with a rotatably driven spreading plate, a feed device feeding the dispensing device and a control device which controls the position of the dispensing device and the spreading plate speed on the one hand Dependent on a predetermined spread image position and on the other hand in dependence on the driving speed and / or the scattering material flow rate controls, including a memory unit for storing adjusted on the driving speed and / or the scattering material flow settings for the position of the dispensing device and / or the spreading plate speed and of the dependency the position of the dispensing device and / or the spreading plate speed of the driving speed and / or the scattering material throughput characteristic relationships is provided ,

Winterdienstfahrzeuge, welche mit einem Streugerät zum Ausbringen von Streustoff ausgestattet sind, sind durch ihren Einsatz zur Glättebekämpfung auf Straßen aller Art allgemein bekannt. Je nach den Einsatzbedingungen können dabei als zur Glättebekämpfung verwendete Streustoffe insbesondere Split, Salz oder ein Salz-Split-Gemisch, jeweils trocken oder befeuchtet, zum Einsatz kommen. Bei herkömmlichen Winterdienstfahrzeugen stellt der Fahrer dabei das Streubild, d.i. die Breite des bestreuten Streifens und dessen Lage relativ zum Winterdienstfahrzeug, und die Streudichte (Streustoffdosierung als Streustoffmenge pro Flächeneinheit) an einem im Führerhaus angeordneten Bedienpult ein. Bekannt ist indessen auch, diese beiden Parameter während eines Streueinsatzes entlang bekannter Streckenabschnitte laufend automatisch vorzugeben, insbesondere unter Verwendung von Positionsdaten des Winterdienstfahrzeuges sowie von für die meteorologische Situation (Temperatur, Feuchtigkeit, Art und Menge von Niederschlägen) charakteristischen Daten. Die insbesondere für die Lage des bestreuten Streifens relativ zum Winterdienstfahrzeug (symmetrisch oder aber asymmetrisch mehr oder weniger weit nach links oder rechts versetzt) maßgebliche Stellung der Ausbringeinrichtung kann dabei namentlich durch den Auftreffpunkt des Streustoffes auf dem Streuteller bestimmt sein, der sich insbesondere durch Variation der relativen Lage des Streutellers und einer diesen beschickenden Schütte zueinander verändern läßt.Winter service vehicles, which are equipped with a spreader for spreading spreading material, are well known by their use for anti-smoothness on roads of all kinds. Depending on the conditions of use, it is possible in particular to use split, salt or a salt-split mixture, in each case dry or moistened, as scattering agents used to control smoothness. In conventional winter maintenance vehicles, the driver sets the scatter pattern, ie the width of the streaked strip and its position relative to the winter maintenance vehicle, and the spreading density (Streptoffdosierung as scattering amount per unit area) on a control panel arranged in the cab. However, it is also known to automatically specify these two parameters continuously during a scattering operation along known route sections, in particular using position data of the winter maintenance vehicle and of data relevant to the meteorological situation (temperature, humidity, type and amount of precipitation). The particular for the location of the streaked strip relative to the winter service vehicle (symmetrically or asymmetrically more or less offset to the left or right) relevant position of the dispensing device may be determined by the impact point of the scattering material on the scattering plate, in particular by varying the Relative position of the spreading plate and a chimney that feeds them change each other.

In dem Bewußtsein, daß einerseits zu wenig und/oder auf einen falschen Bereich der Fahrbahn ausgebrachter Streustoff die Wirksamkeit der Glättebekämpfung reduziert und daß andererseits eine zu hohe ausgebrachte Streustoffmenge sowohl unter Kosten- und auch unter Umweltgesichtspunkten nachteilig ist, wurde in den vergangenen Jahren intensiv an der Optimierung der Streustoffausbringung gearbeitet. Das Ergebnis hiervon sind verschiedene Vorschläge einer Steuerung der Ausbringeinrichtung unter Berücksichtigung mehrerer - den jeweiligen Betriebspunkt definierender - Betriebsparameter des Winterdienstfahrzeugs, d.h. nicht nur in Abhängigkeit von der vorgegebenen Streubildlage, sondern auch unter Berücksichtigung beispielsweise der Fahrgeschwindigkeit und/oder des Streustoffdurchsatzes. Entsprechende gattungsgemäße Winterdienstfahrzeuge, bei denen in diesem Sinne die Stellung der Ausbringeinrichtung und die Drehzahl des Streutellers nicht nur von der vorgegebenen Streubildlage abhängen, zeichnen sich demgemäß dadurch aus, daß in der Speichereinheit der Steuereinrichtung auch für die Abhängigkeit der Stellung der Ausbringeinrichtung und/oder die Streutellerdrehzahl von der Fahrgeschwindigkeit und/oder dem Streustoffdurchsatz charakteristischen Zusammenhänge abspeicherbar sind. In der EP 0563805 B1 und der DE 10328116 A1 werden hierzu verschiedene qualitativ definierte Korrektureingriffe angegeben, mittels derer Grundeinstellungen für die Streuteller-Drehzahl und die Stellung der Ausbringeinheit in Abhängigkeit von der Fahrgeschwindigkeit und dem Streustoff-Durchsatz gleich- oder aber gegensinnig hierzu modifiziert werden. Ferner ist vorgeschlagen worden ( DE 10301285 A1 ), bei der Verteilung von mit Flüssigkeit vermengtem Streustoff mittels eines rotierenden Streutellers das Verhältnis von Flüssigkeitsmenge und Streustoffmenge abhängig von einem oder mehreren Streuparametern wie dem Streustoffdurchsatz oder der Streubreite anzupassen, um eine Vergleichmäßigung des Streubildes bei sich ändernden Streuparametern zu erreichen.Aware that on the one hand too little and / or spread on a wrong area of the road surface scattering reduces the effectiveness of the anti-slipperiness and that on the other hand too high a spread amount of dust is disadvantageous from both cost and environmental point of view has been intense in recent years worked on the optimization of the spreading material application. The result of this are various proposals for controlling the application device taking into account several operating parameters of the winter maintenance vehicle defining the respective operating point, ie not only as a function of the predefined spread image position but also taking into account for example the driving speed and / or the scattering material throughput. Corresponding generic winter service vehicles, at which in this sense the position of the dispensing device and the speed of the spreading plate not only depend on the predetermined spread image position, are characterized accordingly characterized in that in the storage unit of the control device also for the dependence of the position of the dispensing device and / or the spreading plate speed of the driving speed and / or the scattering substance throughput characteristic relationships are stored. In the EP 0563805 B1 and the DE 10328116 A1 For this purpose, various qualitatively defined corrective interventions are specified, by means of which basic settings for the spreading plate speed and the position of the application unit as a function of the driving speed and the spreading material throughput are modified in the same way or in opposite directions. Furthermore, it has been proposed ( DE 10301285 A1 ), in the distribution of mixed with liquid scattering material by means of a rotating spreading plate to adjust the ratio of liquid quantity and scattering amount depending on one or more scattering parameters such as the scattering rate or the spread to achieve a homogenization of the scattering pattern with changing scattering parameters.

Gemessen an den Hoffnungen, die in die Verwendung solcher Steuerungen mit Korrekturalgorithmen gesetzt wurden, ist das mit solchermaßen ausgeführten Streugeräten unter praktischen Einsatzbedingungen erzielbare Ergebnis häufig enttäuschend. Insbesondere zeigen sich auch bei entsprechend ausgeführten Winterdienstfahrzeugen häufig nicht unerhebliche Abweichungen des Streubildes von der gewünschten Lage.Given the hopes that have been placed in the use of such controls with correction algorithms, the result achieved with such spreaders under practical conditions is often disappointing. In particular, not inconsiderable deviations of the scattering pattern of the desired location often show even with correspondingly executed winter maintenance vehicles.

Im Lichte des vorstehend dargelegten Standes der Technik besteht die Zielsetzung der vorliegenden Erfindung darin, ein Winterdienstfahrzeug der eingangs angegebenen Art zu schaffen, welches sich durch ein verbessertes Streuverhalten, d.h. insbesondere eine verbesserte Einhaltung des vorgegebenen Streubildes bei unterschiedlichen Betriebszuständen auszeichnet.In the light of the prior art set out above, the object of the present invention is to provide a winter utility vehicle of the kind set forth, which is characterized by an improved scattering behavior, i. In particular, an improved compliance with the predetermined spread pattern at different operating conditions is characterized.

Gelöst wird die vorstehend angegebene Aufgabenstellung gemäß der vorliegenden Erfindung, indem bei einem Winterdienstfahrzeug der eingangs angegebenen Art zumindest die für die Abhängigkeit der Stellung der Ausbringeinrichtung und/oder die Streutellerdrehzahl von der Fahrgeschwindigkeit und/oder dem Streustoffdurchsatz charakteristischen Zusammenhänge durch den Nutzer des Winterdienstfahrzeugs mittels einer der Steuereinrichtung zugeordneten Eingabeeinheit individuell und nutzungsspezifisch eingebbar sind. Die vorliegende Erfindung löst sich somit vollständig von dem bisher beschrittenen Weg, indem nicht eine - ggfs. durch den Nutzer des Winterdienstfahrzeugs spezifisch vorgebbare - Grundeinstellung der Ausbringeinheit insbesondere hinsichtlich deren Stellung und/oder der Streutellerdrehzahl in Anwendung eines in der Steuereinrichtung fest hinterlegten generellen Korrekturalgorithmus' in Abhängigkeit von der Fahrgeschwindigkeit des Winterdienstfahrzeugs, dem Streustoff-Durchsatz durch die Fördereinrichtung und/oder anderen Betriebsparametern modifiziert wird, sondern vielmehr die für die Abhängigkeit der Stellung der Ausbringeinrichtung und/oder die Streutellerdrehzahl von den jeweils berücksichtigten Betriebsparametern charakteristischen Zusammenhänge durch den Nutzer des Winterdienstfahrzeugs individuell und nutzungsspezifisch eingebbar sind. Die Erfindung baut auf diese Weise auf der Erkenntnis auf, daß es für die Einhaltung von Vorgaben durch das Streubild maßgeblich auf die Kompensation betriebspunktabhängiger dynamischer Effekte ankommt, welche hinwiederum stark von den individuellen Betriebsbedingungen des einzelnen Winterdienstfahrzeugs beeinflußt sind. Durch die erfindungsgemäße nutzungsspezifische Vorgabe der betriebspunkt- bzw. betriebszustandsabhängigen Beeinflussung bzw. Modifikation von Einstellwerten läßt sich in einer bisher nicht gekannten Weise das jeweilige Streugerät durch seinen Nutzer sowohl an die spezifische Konfiguration mit einem bestimmten Trägerfahrzeug als auch an bestimmte Betriebsweisen des Winterdienstfahrzeugs anpassen. Dies stellt ein grundlegend neues Konzept dar, aus dessen Anwendung eine ganze Reihe von Vorteilen resultiert. Besonders hervorzuheben ist insoweit, daß in Anwendung der vorliegenden Erfindung die spezifischen Besonderheiten des jeweils zum Einsatz kommenden Trägerfahrzeugs bei der Steuerung des Streugeräts berücksichtigt werden können. Durch die nutzungsspezifisch hinterlegten Zusammenhänge werden insbesondere unterschiedliche Strömungsverhältnisse hinter Trägerfahrzeugen unterschiedlicher Hersteller und/oder Bauweisen korrigiert, die sich namentlich durch die in erheblichem Maße unterschiedlich gestalteten Führerhäuser ergeben und bei gattungsgemäßen Winterdienstfahrzeugen nach dem Stand der Technik zu den Streubilddifferenzen beitragen. Entsprechendes gilt auch für die spezifische Ausstattung des betreffenden Winterdienstfahrzeugs mit Anbaugeräten wie insbesondere Schneepflügen. Nicht nur die Auswirkungen des Anbaus eines Schneepfluges als solchen auf die hinter dem Winterdienstfahrzeug herrschenden Strömungsverhältnisse (bei den unterschiedlichen Fahrgeschwindigkeiten) lassen sich in Anwendung der Erfindung berücksichtigen und korrigieren; auch die spezifischen Einflüsse unterschiedlicher Pfluggestaltungen (Abmessungen; mit oder ohne Windleitschirm) lassen sich über die nutzungsspezifisch hinterlegten Zusammenhänge korrigieren. Auch Besonderheiten des örtlich eingesetzten Streustoffes (z.B. untypische Korngrößen und/oder Kornformen von Split), die sich auf das Streubild auswirken, werden bei erfindungsgemäßen Winterdienstfahrzeugen durch die Verwendung nutzungsspezifischer, individueller, auf die Einstellwerte angewandter Korrekturzusammenhänge korrigiert.The object specified above according to the present invention is achieved by at least the relationships characteristic of the dependence of the position of the dispensing device and / or the spreading plate rotational speed on the driving speed and / or the spreading material throughput on a winter service vehicle of the type specified at the outset by the user of the winter maintenance vehicle by means of a the control unit associated input unit are individually and user-specific entered. The present invention is thus completely detached from the hitherto pursued path, by not a - possibly by the user of winter maintenance vehicle specifiable - Basic setting of the application unit in particular with regard to their position and / or the spreading plate speed in application of a permanently stored in the control device general correction algorithm depending on the driving speed of the winter maintenance vehicle, the spreading material throughput through the conveyor and / or other operating parameters is modified, but rather for the dependence of the position of the application and / or the spreading plate speed of the respectively considered operating parameters characteristic relationships by the user of the winter maintenance vehicle individually and usage-specific can be entered. The invention builds on the knowledge on the fact that it depends largely on the compensation of operating point-dependent dynamic effects for the compliance of specifications by the scattering image, which in turn are strongly influenced by the individual operating conditions of each winter maintenance vehicle. By virtue of the use-specific predefinition of the operating point-dependent or operating state-dependent influencing or modification of setting values, the respective spreader can be adapted by its user both to the specific configuration with a specific carrier vehicle and to specific modes of operation of the winter utility vehicle in a hitherto unknown manner. This represents a fundamentally new concept, the application of which results in a whole series of advantages. In particular, it should be emphasized that, in application of the present invention, the specific features of the carrier vehicle used in each case can be taken into account in the control of the spreader. The use-specifically deposited relationships in particular different flow conditions are corrected behind carrier vehicles of different manufacturers and / or designs, which result in particular by the cabs designed to a considerable extent and contribute to the scattered image differences in generic winter maintenance vehicles according to the prior art. The same applies to the specific equipment of the winter maintenance vehicle concerned with attachments such as snow plows in particular. Not just the effects of growing a snow plow as such on the prevailing behind the winter maintenance vehicle flow conditions (at the different speeds) consider and correct themselves in application of the invention; The specific influences of different plow designs (dimensions, with or without wind deflector) can also be corrected using the context-specific relationships. Also specifics of the locally applied scattering material (eg untypical grain sizes and / or grain shapes of split), which have an effect on the scattering pattern, are corrected in winter service vehicles according to the invention by the use of use-specific, individual correction contexts applied to the setting values.

An die Steuereinrichtung ist typischerweise ein zur Vorgabe der Streubildlage dienendes Bedienpult angeschlossen; dies schließt allerdings nicht aus, daß auf vorher einprogrammierten Einsatzrouten bzw. Streckenabschnitten die Vorgaben auch automatisch in die Steuereinrichtung eingespeist werden können, und zwar unter Berücksichtigung der laufend automatisch ermittelten aktuellen Position des Winterdienstfahrzeugs (z.B. mittels GPS) und abgespeicherter routenabhängiger Solldaten.To the control device typically serving to specify the spread image position control panel is connected; However, this does not preclude the fact that the defaults can also be fed automatically into the control device on previously programmed deployment routes or sections, taking into account the current automatically ascertained current position of the winter service vehicle (for example by means of GPS) and stored route-dependent setpoint data.

Die jeweils anwendbaren individuell vorgebbaren Korrekturzusammenhänge können dabei auf unterschiedliche Weise festgelegt werden. So können durchaus spezifische Kurvenverläufe durch hierfür charakteristische Funktionen definiert werden. Besonders bevorzugt ist indessen, wenn die individuell vorgebbaren Korrekturzusammenhänge durch eine Mehrzahl diskreter Werte definiert sind, welche die maßgebliche Einflußnahme auf die auf einen Auslegungsbetriebspunkt bzw. -betriebszustand bezogenen Einstellwerte bei ausgewählten anderen Betriebspunkten bzw. Betriebszuständen des spezifischen Winterdienstfahrzeugs beinhalten. In diesem Sinne sind gemäß einer bevorzugten Weiterbildung der Erfindung in der Speichereinheit der Steuereinrichtung mehrere diskrete, auf unterschiedliche Betriebspunkte bezogene individuelle, nutzungsspezifische Einstellwerte abspeicherbar und weist die Steuereinrichtung eine der Ermittlung von Zwischenwerten zu den Einstellwerten dienende Interpolationseinheit auf. Dies gestattet die Nutzung der Vorteile der Erfindung über einen breiten Betriebsbereich selbst dann, wenn nur eine vergleichsweise geringe Anzahl spezifischer, auf einzelne Betriebspunkte bezogener Einstellwerte in der Speichereinheit abgelegt ist, zwischen denen der spezifische Korrekturwert durch Interpolation ermittelt wird. Eine solche Interpolationseinheit kann im Falle eines außerhalb der Einstellwerte liegenden Betriebspunktes den maßgeblichen Korrekturwert auch durch Extrapolation ermitteln.The respectively applicable individually definable correction contexts can be determined in different ways. Thus, specific curves can be defined by characteristic functions. However, it is particularly preferred if the individually predefinable correction relationships are defined by a plurality of discrete values, which are the decisive influence on the setting values relating to a design operating point or operating state at selected other operating points or operating states of the specific winter service vehicle. In this sense, according to a preferred development of the invention, a plurality of discrete, use-specific setting values related to different operating points can be stored in the memory unit of the control device, and the control device has an interpolation unit serving to determine intermediate values for the setting values. This allows the advantages of the invention to be exploited over a wide operating range even if only a comparatively small number of specific setting values relating to individual operating points are stored in the memory unit, between which the specific correction value is determined by interpolation. Such an interpolation unit can also determine the relevant correction value by extrapolation in the case of an operating point that lies outside of the setting values.

Gemäß einer anderen Weiterbildung der Erfindung ist vorgesehen, daß die Steuereinrichtung des Winterdienstfahrzeugs einen Basisstellungs-Kennfeldspeicher, in dem ein einem Nennbetriebspunkt zugeordnetes Basisstellungs-Kennfeld mit einem Basis-Sollstellungswert der Ausbringeinheit für jedes durch die Streubreite links und die Streubreite rechts von einem fahrzeugfesten Bezugspunkt dargestellte Wertepaar abgespeichert ist, und einen Stellungs-Korrekturwertspeicher, in dem mindestens ein Stellungs-Korrekturwert zur betriebspunktabhängigen Korrektur der Basis-Sollstellungswerte abgespeichert ist, umfaßt, wobei der mindestens eine Stellungs-Korrekturwert mittels der Eingabeeinheit spezifisch und individuell durch den Nutzer eingebbar ist. Besonders bevorzugt sind dabei in dem Stellungs-Korrekturwertspeicher mehrere Stellungs-Korrekturwerte abgespeichert, die jeweils zweien der drei Parameter Streudichte, Fahrgeschwindigkeit und Streustoff-Durchsatz zugeordnet sind und - gemäß dem jeweiligen momentanen Betriebspunkt des Winterdienstfahrzeugs - in Abhängigkeit von diesen Parametern zur Korrektur des jeweiligen Basis-Sollstellungswerts eingesetzt werden. Optimale Ergebnisse lassen sich dabei erzielen, wenn jedem einzelnen Wertepaar des Basisstellungs-Kennfeldes eine eigene Stellungs-Korrekturwertreihe mit mehreren Stellungs-Korrekturwerten zugeordnet ist, deren einzelne Korrekturwerte jeweils zweien der drei Parameter Streudichte, Fahrgeschwindigkeit und Streustoff-Durchsatz zugeordnet sind. Wenn das Streugerät bei einem bestimmten Betriebspunkt betrieben wird, wird der diesem Betriebspunkt zugeordnete Stellungs-Korrekturwert der Korrektur des Basis-Sollstellungswerts zugrundegelegt. Bei Betriebspunkten zwischen solchen, denen spezifische Stellungs-Korrekturwerte zugeordnet sind, kommt die weiter oben bereits angesprochene Interpolation zum Einsatz. Als durch die Streubreite links und die Streubreite rechts von einem fahrzeugfesten Bezugspunkt dargestelltes Wertepaar im Sinne der vorstehenden Ausführungen ist auch anzusehen, wenn die Streubreite links und die Streubreite rechts von einem fahrzeugfesten Bezugspunkt durch die Gesamtstreubreite sowie die Lage des bestreuten Streifens relativ zu einem fahrzeugfesten Bezugspunkt definiert werden.According to another embodiment of the invention, it is provided that the control device of the winter maintenance vehicle a base position map memory in which a nominal operating point associated base position map with a base setpoint value of the application unit for each represented by the scatter width left and the spread to the right of a vehicle-fixed reference point Value pair is stored, and a position correction value memory, in which at least one position correction value for operating point-dependent correction of the base target position values is stored, wherein the at least one position correction value by means of the input unit specifically and individually entered by the user. Particularly preferred are in the position correction value memory a plurality of position correction values are stored, which are each assigned to two of the three parameters spreading density, driving speed and spreading material throughput and - in accordance with the respective instantaneous operating point of the winter maintenance vehicle - are used as a function of these parameters for correcting the respective basic setpoint value. Optimal results can be achieved if each individual value pair of the base position characteristic map is assigned its own position correction value series with a plurality of position correction values whose individual correction values are assigned to two of the three parameters spreading density, driving speed and spreading material throughput. If the spreader is operated at a certain operating point, the posture correction value associated with that operating point will be used to correct the base target position value. At operating points between those to which specific position correction values are assigned, the interpolation already mentioned above is used. As shown by the spread to the left and the spread to the right of a vehicle-fixed reference point value pair in the sense of the foregoing is also to be considered when the spread left and the spread to the right of a vehicle-fixed reference point by the total spread and the position of the streaked strip relative to a vehicle-fixed reference point To be defined.

Die selben Zusammenhänge, die vorstehend in Verbindung mit der Steuerung der Stellung der Ausbringeinrichtung dargelegt wurden, können alternativ oder additiv in Verbindung mit der Steuerung der Streutellerdrehzahl zur Anwendung gelangen. Zur Vermeidung von Wiederholungen wird insoweit auf eine gesonderte Darstellung verzichtet.The same relationships set forth above in connection with controlling the position of the dispenser may alternatively or additionally be used in conjunction with the control of the spreader plate speed. To avoid repetition is waived in this respect to a separate presentation.

Eine zu der vorstehend dargelegten Ausführungsform alternative Weiterbildung der Erfindung zeichnet sich dadurch aus, daß die Steuereinrichtung einen Basisstellungs-Kennfeldspeicher, in dem ein Basisstellungs-Kennfeld mit einer Basis-Sollstellung der Ausbringeinheit für jedes durch die Streubreite links und die Streubreite rechts von einem fahrzeugfesten Bezugspunkt sowie einen der drei Werte Streudichte, Fahrgeschwindigkeit und Streustoff-Durchsatz dargestellte Wertetriplett abgespeichert ist, und einen Stellungs-Korrekturwertspeicher, in dem für jedes Wertetriplett des Basisstellungs-Kennfeldes mehrere von einem anderen der drei Werte Streudichte, Fahrgeschwindigkeit und Streustoff-Durchsatz abhängige Stellungs-Korrekturwerte zur betriebspunktabhängigen Korrektur der jeweiligen Basis-Sollstellung abgespeichert sind, umfaßt. Die Stellungs-Korrekturwerte werden hierfür, wie auch im Falle der vorstehend angesprochenen Weiterbildung, individuell und für das jeweils konfigurierte Winterdienstfahrzeug spezifisch durch den betreffenden Nutzer während einer Lehr- und Adaptionsphase in den hierfür vorgesehenen Stellungs-Korrekturwertspeicher eingespeist.An embodiment of the invention which is alternative to the above embodiment is characterized in that the control device has a base position map memory in which a base position map with a basic target position of the dispensing unit for each by the scatter width left and the spread to the right of a vehicle-fixed reference point and a position correction value memory, in which for each value triplet of the base position characteristic map, a plurality of position correction values dependent on a different one of the three values of spreading density, driving speed and spreading material throughput are stored for operating point-dependent correction of the respective base target position includes. For this purpose, as in the case of the above-mentioned further development, the posture correction values are fed in individually and for the respectively configured winter service vehicle specifically by the user concerned during a teaching and adaptation phase into the position correction value memory provided for this purpose.

Auch hier gilt, daß sich die vorstehend in Verbindung mit der Steuerung der Stellung der Ausbringeinrichtung dargelegten Zusammenhänge alternativ oder additiv in Verbindung mit der Steuerung der Streutellerdrehzahl anwenden lassen. Zur Vermeidung von Wiederholungen wird insoweit wiederum auf eine gesonderte Darstellung verzichtet.Again, the relationships set forth above in connection with the control of the position of the dispenser may alternatively or additionally be used in conjunction with the control of the spreading plate speed. To avoid repetition is again waived in this respect to a separate presentation.

Für die vorstehend näher erläuterten Ausführungsformen der Erfindung gilt, daß mit der Eingabeeinheit zweckmäßigerweise ein Lernmodus durchführbar ist, in dem die Stellungs- und/oder die Drehzahl-Korrekturwerte mittels einer Stellungs- bzw. Drehzahl-Korrekturwerterfassungsroutine individuell und fahrzeugspezifisch bestimmbar und in dem Stellungs- bzw. Drehzahl-Korrekturwertspeicher abspeicherbar sind. Der Lernmodus vollzieht sich während einer Lehr- und Adaptionsphase; in ihm wird das Winterdienstfahrzeug an vorgegebenen, insbesondere durch die Fahrgeschwindigkeit definierten Betriebspunkten betrieben, und die Einstellwerte für die Ausbringeinrichtung werden so lange nachgezogen, bis das tatsächliche Streubild den an dem Bedienpult eingestellten Vorgaben entspricht. Durch Quittieren werden die so ermittelten Einstellwerte dann als Korrekturwerte in dem zugeordneten Korrekturwert-Speicher hinterlegt.For the embodiments of the invention explained in detail above, a learning mode is expediently feasible with the input unit, in which the position and / or the rotational speed correction values can be determined individually and vehicle-specific by means of a position or rotational speed correction value detection routine and in the posture position. or speed correction value memory can be stored. The learning mode takes place during a teaching and adaptation phase; in it, the winter maintenance vehicle is operated at predetermined, in particular by the driving speed defined operating points, and the set values for the dispensing device are tightened until the actual spreading pattern corresponds to the set on the control panel specifications. By acknowledging, the setting values determined in this way are then stored as correction values in the assigned correction value memory.

Im Rahmen der Erfindung ist es ersichtlich sekundär, ob die Eingabeeinheit baulich ein fester Bestandteil der Steuereinrichtung oder aber ein an die Steuereinrichtung anschließbares Zusatzaggregat ist. Die an zweiter Stelle genannte Variante hat den Vorteil, daß die Möglichkeiten der Umprogrammierung der Steuereinrichtung sich ohne weiteres auf einen begrenzten, hierzu autorisierten Personenkreis beschränken lassen. Allerdings ließe sich ein vergleichbares Ergebnis bei der an erster Stelle dargelegten Variante mit einer in die Steuereinrichtung integrierten Eingabeeinheit durch die Vergabe entsprechender Zugriffsrechte erreichen.In the context of the invention, it can be seen secondarily whether the input unit is structurally a fixed component of the control device or else an additional unit which can be connected to the control device. The second-mentioned variant has the advantage that the possibilities of reprogramming the control device can be limited to a limited, authorized for this purpose group of people readily. However, a comparable result could be achieved in the variant set forth in the first place with an input unit integrated in the control device by granting corresponding access rights.

Eine abermals andere bevorzugte Weiterbildung der Erfindung zeichnet sich dadurch aus, daß in dem vorstehend erläuterten Stellungs-Korrekturwertspeicher und/oder dem Drehzahl-Korrekturwertspeicher zu jedem Wertepaar bzw. Wertetriplett des entsprechenden Basis-Kennfeldes mehrere streustoffspezifische Stellungs- bzw. Drehzahl-Korrekturwertreihen abrufbar abgespeichert sind. Dies trägt dem Umstand Rechnung, daß unterschiedliche Streustoffe ein teilweise in erheblichem Maße voneinander abweichendes Streuverhalten zeigen. Mit der Vorgabe eines bestimmten Streustoffs an dem Bedienpult greift die Steuereinrichtung im Rahmen des zugehörigen Steuerungsprogramms selbsttätig auf die diesem spezifischen Streustoff zugeordneten Korrekturwerte zurück. Alternativ hierzu kann vorgesehen sein, daß in dem vorstehend erläuterten Stellungs-Korrekturwertspeicher und/oder dem Drehzahl-Korrekturwertspeicher zu jedem Wertepaar bzw. Wertetriplett des entsprechenden Basis-Kennfeldes jeweils ein streustoffspezifischer Datensatz mit entsprechenden streustoffspezifischen Stellungs- bzw. Drehzahl-Korrekturwertreihen über die Eingabeeinheit abspeicherbar sind. Statt streustoffspezifisch auf die Korrekturwerte Einfluß zu nehmen, können in entsprechender Weise auch in dem vorstehend erläuterten Basisstellungs- und/oder Basisdrehzahl-Kennfeldspeicher mehrere streustoffspezifische Basis-Kennfelder abrufbar abgespeichert oder aber über die Eingabeeinheit abspeicherbar sein.A yet another preferred embodiment of the invention is characterized in that in the above-described position correction value memory and / or the speed correction value memory for each pair of values or value triplet of the corresponding base map multiple scatter-specific position or speed correction value rows are stored retrievable , This takes into account the fact that different scattering substances show a scattering behavior that sometimes differs considerably from one another. With the specification of a specific scattering substance on the operating panel, the control device automatically accesses the correction values assigned to this specific scattering substance as part of the associated control program. Alternatively, it can be provided that in the above-described position correction value memory and / or the speed correction value memory for each pair of values or value triplet of the corresponding base map each a scatter-specific data record with corresponding scattering-specific position or speed correction value series via the input unit can be stored are. Instead of influencing the correction values in a scattering-specific manner, a plurality of scattering substance-specific basic characteristic maps can be stored in a corresponding manner also in the base position and / or base speed map memory explained above, or they can be stored via the input unit.

Weiterhin ist es günstig, wenn in dem Basisstellungs-und/oder dem Basisdrehzahl-Kennfeldspeicher mehrere betriebsartspezifische Basis-Kennfelder und/oder in dem Stellungs-Korrekturwertspeicher und/oder dem Drehzahl-Korrekturwertspeicher mehrere betriebsartspezifische Stellungs- bzw. Drehzahl-Korrekturwertreihen abrufbar abgespeichert bzw. über die Eingabeeinheit abspeicherbar sind. Als unterschiedliche Betriebsarten, deren Auswirkungen auf das Streubild sich auf diese Weise kompensieren lassen, sind in diesem Sinne beispielsweise unterschiedliche Ausstattungsvarianten des betreffenden Winterdienstfahrzeugs anzusehen, namentlich die beiden Betriebsarten mit bzw. ohne einen angebauten Frontschneepflug oder aber die drei Betriebsarten mit ausgeschwenktem, mit angelegtem bzw. ohne Seitenschneepflug. Als unterschiedliche Betriebsarten in diesem Sinne können auch präventive Streueinsätze mit einem in dessen Transportstellung angehobenen, nach links oder aber nach rechts angestellten Frontschneepflug angesehen werden; denn bei der vergleichsweise hohen Fahrgeschwindigkeit des Winterdienstfahrzeugs während eines präventiven Streueinsatzes wirkt sich die Orientierung der Anstellung des Schneepfluges durchaus auf die Strömungsverhältnisse hinter dem Winterdienstfahrzeugs und somit auf die Verteilung des von der Ausbringeinrichtung abgeworfenen Streustoffes aus. Damit die jeweilige Betriebsart von der Steuereinrichtung berücksichtigt werden kann, weist das zugehörige Bedienpult zweckmäßigerweise ein entsprechendes Betriebsarten-Schaltelement auf.Furthermore, it is favorable if in the base position and / or the base speed characteristic map memory several mode-specific basic maps and / or in the position correction value memory and / or the speed correction value memory several mode-specific Position or speed correction value rows can be stored in a retrievable manner or stored via the input unit. As different modes of operation, the effects of which can be compensated on the scattering pattern, in this sense, for example, different equipment variants of the respective winter service vehicle to look at, namely the two modes with or without a mounted front snow plow or the three modes with swung out, with invested or without side snow plow. As different modes of operation in this sense, preventive spreading inserts can be considered with a raised in the transport position, to the left or to the right employed front snowplow; because at the comparatively high driving speed of the winter maintenance vehicle during a preventive litter application, the orientation of the employment of the snowplough definitely affects the flow conditions behind the winter maintenance vehicle and thus on the distribution of the discarded by the spreading litter. So that the respective operating mode can be taken into account by the control device, the associated operating panel expediently has a corresponding operating mode switching element.

Ersichtlich läßt sich die vorliegende Erfindung auch dadurch technisch umsetzen, daß sich die gesamten der Steuerung der Ausbringeinheit zugrundeliegenden Daten über die Eingabeeinheit individuell und nutzungsspezifisch, d.h. zur Anpassung des Streugeräts insbesondere an bestimmte Streustoffe oder Betriebsarten des Winterdienstfahrzeugs, durch den Nutzer ersetzen lassen. Im übrigen ist es für die Umsetzung der vorliegenden Erfindung unerheblich, ob die Ausbringeinrichtung einen oder mehrere Streuteller aufweist, wobei in dem an zweiter Stelle genannten Fall die Streuteller im Sinne der Erzielung eines optimalen Gesamtstreubildes aufeinander abgestimmt gesteuert werden.Obviously, the present invention can also technically implement the fact that the entire underlying the control of the application unit data on the input unit individually and use-specific, ie to adapt the spreader particular to certain scattering substances or operating modes of the winter maintenance vehicle, can be replaced by the user. Otherwise, it is for the implementation of the present invention irrelevant whether the dispensing device has one or more scattering plates, wherein in the second case mentioned the scattering plates are controlled in the sense of achieving an optimal Gesamtstreubildes coordinated.
