Description

Die Erfindung betrifft eine Pistenraupe mit einem Fahrgestell und zwei auf gegenüberliegenden Seiten des Fahrgestells angeordneten Kettenlaufwerken, sowie mit wenigstens einem Anbaugerät zur Bearbeitung einer Schneefläche.The invention relates to a snowcat with a chassis and two crawler tracks arranged on opposite sides of the chassis, as well as with at least one attachment for working on a snow surface.

Eine derartige Pistenraupe ist aus der DE 101 41 155 A1 bekannt. Die bekannte Pistenraupe weist ein Fahrgestell sowie links- und rechtsseitig des Fahrgestells angeordnete Kettenlaufwerke auf. Heckseitig ist die Pistenraupe mit einem Anbaugerät in Form einer Heckfräse versehen. Die Pistenraupe weist Sensoren zum direkten oder indirekten Erfassen eines Ist-Zustandes der von der Heckfräse zu bearbeitenden Pistenoberfläche auf. Als Sensoren zum direkten Erfassen der Pistenoberfläche sind berührend oder berührungslos arbeitende Sensoren vorgesehen, die der Pistenoberfläche zugewandt sind. Abhängig von erfassten Sensordaten wird die Heckfräse mittels einer Steuereinheit so gesteuert, dass sich eine gleichmäßige Pistenoberfläche ergibt. Maßgeblich ist dabei die Oberflächentopografie der Piste mit Gefällen, Steigungen, Übergängen zu einer ebenen Piste, Überfahren einer Kuppe oder Ähnliches. Denn hierdurch verändert die Pistenraupe beim Befahren der entsprechenden Pistenoberfläche permanent ihre Lage und Ausrichtung. Die Oberflächensensorik soll dazu dienen, solche sich ändernden Konturen zu erfassen und zu gewährleisten, dass die Heckfräse trotz der sich während des Fahrbetriebs permanent verändernden Lage der Pistenraupe immer eine gleichmäßige Bearbeitung der Pistenoberfläche vornimmt.Such a snowcat is from the DE 101 41 155 A1 known. The known snow groomer has a chassis and crawler tracks arranged on the left and right of the chassis. At the rear, the snow groomer is equipped with an attachment in the form of a rear tiller. The snow groomer has sensors for the direct or indirect detection of an actual state of the slope surface to be processed by the rear tiller. As sensors for direct detection of the runway surface, contacting or non-contacting sensors are provided, which face the runway surface. Depending on the recorded sensor data, the rear tiller is controlled by a control unit in such a way that the slope surface is even. The decisive factor is the surface topography of the slope with slopes, inclines, transitions to a level slope, driving over a hilltop or the like. This is because the snow groomer permanently changes its position and orientation when driving on the corresponding slope surface. The surface sensors are intended to detect such changing contours and to ensure that the rear tiller always processes the slope surface evenly despite the constantly changing position of the snowcat.

Aufgabe der Erfindung ist es, eine Pistenraupe der eingangs genannten Art zu schaffen, die eine gegenüber dem Stand der Technik verbesserte Schneeflächenbearbeitung ermöglicht.The object of the invention is to create a snowcat of the type mentioned at the outset which enables snow surface cultivation to be improved compared with the prior art.

Diese Aufgabe wird dadurch gelöst, dass an einem Tragwerksabschnitt des Fahrgestells und/oder des Anbaugerätes wenigstens ein Messaufnehmer vorgesehen ist, der zumindest in einem Fahrbetrieb der Pistenraupe kontinuierlich in eine Schneeschicht der Schneeoberfläche über eine definierte Schichttiefe eintaucht und eine Kraftsensorik und/oder eine Temperatursensorik aufweist, die derart an dem Messaufnehmer angeordnet sind, dass in Schichttiefenrichtung der Schneeschicht gesehen kontinuierlich wenigstens zwei Messwerte für eine Schneehärte und/oder eine Schneetemperatur in unterschiedlicher Schichttiefe aufnehmbar sind. Die erfindungsgemäße Lösung erfasst während eines Fahrbetriebs der Pistenraupe permanent verschiedene Parameter einer Schneeschicht der Schneefläche über eine definierte Schichttiefe, wodurch ein Schneepistenaufbau erfasst werden kann. Dabei wird insbesondere die sich über die Schichttiefe verändernde Härte der Schneefläche und die sich über die Schichttiefe ändernde Temperatur der Schneefläche erfasst. So kann insbesondere erkannt werden, dass auf eine angeschmolzene, weiche obere Schicht eine härtere untere Schicht folgt, oder umgekehrt, dass eine eigentlich weiche untere Schicht von einer gefrorenen oberen Eisschicht überzogen ist und Ähnliches. Ein solcher Messaufnehmer ist vorzugsweise im Bereich einer Fahrzeugmitte der Pistenraupe - in Fahrzeuglängsrichtung gesehen - positioniert, so dass eine Schneeschicht zwischen den gegenüberliegenden Kettenlaufwerken erfasst wird, die nicht durch die Ketten der Kettenlaufwerke verdichtet und beunruhigt ist. Dabei kann der wenigstens eine Messaufnehmer im Bereich einer Unterseite des Fahrgestells der Pistenraupe selbst, oder im Bereich eines front- oder heckseitigen Anbaugerätes positioniert sein. Der wenigstens eine Messaufnehmer ist jeweils an einem stabilen Tragwerksabschnitt des Fahrgestells oder des front- oder heckseitigen Anbaugerätes befestigt.This object is achieved in that at least one measuring sensor is provided on a supporting structure section of the chassis and / or the attachment, which, at least when the snow groomer is driving, continuously dips into a layer of snow on the snow surface over a defined layer depth and has force sensors and / or temperature sensors which are arranged on the measuring transducer in such a way that, viewed in the direction of the depth of the snow layer, at least two measured values for a snow hardness and / or a snow temperature at different depths can be recorded continuously. The solution according to the invention continuously records various parameters of a snow layer of the snow surface over a defined layer depth while the snow groomer is in operation, whereby a snow slope structure can be recorded. In particular, the hardness of the snow surface, which changes over the depth of the layer, and the The temperature of the snow surface changes over the depth of the layer. In particular, it can be recognized that a melted, soft upper layer is followed by a harder lower layer, or vice versa, that an actually soft lower layer is covered by a frozen upper layer of ice and the like. Such a measuring sensor is preferably positioned in the area of a vehicle center of the snow groomer - viewed in the vehicle longitudinal direction - so that a layer of snow is detected between the opposing crawler tracks, which is not compacted and disturbed by the chains of the crawler tracks. The at least one measuring sensor can be positioned in the area of an underside of the chassis of the snow groomer itself, or in the area of a front or rear attachment. The at least one measuring sensor is each attached to a stable supporting structure section of the chassis or of the front or rear attachment.

In Ausgestaltung der Erfindung ist der Messaufnehmer schwertförmig ausgeführt. Die schwertförmige Ausführung ist bezüglich des im Fahrbetrieb in der Schneefläche erzeugten Widerstandes besonders günstig. Dabei ist die Schwertform in Fahrzeuglängsrichtung ausgerichtet, so dass der schwertförmige Messaufnehmer nach Art eines Bootsschwertes eines Segelbootes in die Schneefläche eintaucht.In an embodiment of the invention, the sensor is designed in the shape of a sword. The sword-shaped design is particularly favorable with regard to the resistance generated in the snow surface when driving. The sword shape is aligned in the longitudinal direction of the vehicle, so that the sword-shaped measuring sensor dips into the snow surface like a boat sword of a sailing boat.

In weiterer Ausgestaltung der Erfindung ist der Messaufnehmer zwischen einer Ruhestellung und einer Messstellung beweglich angeordnet. Diese Ausgestaltung ermöglicht ein Anheben des Messaufnehmers in eine Ruhestellung und ein Absenken in die Messstellung, so dass die Pistenraupe bei Überfahren eines schneefreien Untergrundes nicht durch den Messaufnehmer behindert ist und darüber hinaus eine Beschädigung des Messaufnehmers bei Befahren von schneefreiem oder schneearmem Untergrund verhindert wird. Die bewegliche Anordnung kann relativ zu dem Tragwerksabschnitt oder gemeinsam mit dem Tragwerksabschnitt vorgesehen sein. In letzterem Fall ist der Messaufnehmer an dem Tragwerksabschnitt fest angeordnet, aber der Tragwerksabschnitt als Ganzes ist relativ zu der Pistenraupe beweglich. Im ersten Fall ist der Messaufnehmer beweglich an dem Tragwerksabschnitt gelagert.In a further embodiment of the invention, the measuring sensor is arranged to be movable between a rest position and a measuring position. This configuration enables the sensor to be raised to a rest position and lowered to the measurement position, so that the snowcat is not hindered by the sensor when driving over a snow-free surface and, in addition, damage to the sensor is prevented when driving over a snow-free or poorly snowed surface. The movable arrangement can be provided relative to the structural section or together with the structural section. In the latter case, the measuring sensor is fixedly arranged on the supporting structure section, but the supporting structure section as a whole is movable relative to the snow groomer. In the first case, the sensor is movably mounted on the supporting structure section.

In weiterer Ausgestaltung der Erfindung ist eine elektronische Steuereinheit vorgesehen, die mit der Kraftsensorik und/oder der Temperatursensorik gekoppelt ist, und die von der Kraftsensorik und/oder der Temperatursensorik übermittelte Messwerte auswertet. Erfindungsgemäß weist der Messaufnehmer entweder eine Kraftsensorik oder eine Temperatursensorik oder sowohl eine Kraftsensorik als auch eine Temperatursensorik auf. Die elektronische Steuereinheit ist mit einer Software versehen, die in geeigneter Weise eine Auswertung der von der Kraftsensorik und/oder der Temperatursensorik übermittelten Messwerte vornimmt. Durch die Auswertung wird eine automatische Einstellung verschiedener Funktionsparameter wie Fahrgeschwindigkeitsanpassung der Pistenraupe sowie Frästiefe, Fräsdrehzahl und Anpressdruck einer Heckfräse auf optimierte Werte ermöglicht. Dabei werden vorteilhaft entsprechende Daten bereits in einer Lernphase der Steuereinheit erfasst und in einer Datenbank abgelegt, so dass über geeignete Auswertealgorithmen ein selbstlernendes System geschaffen wird. Durch Vergleich mit als optimal angesehenen Sollwerten der Datenbank ist eine Regelung der Funktionsparameter ermöglicht, um eine Optimierung der Pistenbearbeitung zu erzielen.In a further embodiment of the invention, an electronic control unit is provided which is coupled to the force sensor system and / or the temperature sensor system and which evaluates the measured values transmitted by the force sensor system and / or the temperature sensor system. According to the invention, the measuring transducer has either a force sensor system or a temperature sensor system or both a force sensor system and a temperature sensor system. The electronic control unit is provided with software that evaluates the measured values transmitted by the force sensor system and / or the temperature sensor system in a suitable manner. The evaluation ensures that various functional parameters such as Adjustment of the driving speed of the snowcat as well as the milling depth, milling speed and contact pressure of a rear milling machine enables optimized values. Corresponding data are advantageously already recorded in a learning phase of the control unit and stored in a database, so that a self-learning system is created using suitable evaluation algorithms. By comparison with setpoint values in the database that are considered to be optimal, it is possible to regulate the functional parameters in order to optimize the slope cultivation.

In weiterer Ausgestaltung der Erfindung ist der Steuereinheit eine Anzeigeeinrichtung zugeordnet, die Auswertungen der Messwerte anzeigt. Die Anzeigeeinrichtung ist vorzugsweise stationär in einem Fahrerhaus der Pistenraupe oder aber mobil auf einem elektronischen Peripheriegerät wie insbesondere einem Smartphone, einem Tablet oder einem Laptop vorgesehen. Eine Zuordnung der Anzeigeeinrichtung zur Steuereinheit kann drahtgebunden oder drahtlos erfolgen.In a further embodiment of the invention, the control unit is assigned a display device which displays evaluations of the measured values. The display device is preferably provided stationary in a driver's cab of the snow groomer or mobile on an electronic peripheral device such as in particular a smartphone, a tablet or a laptop. The display device can be assigned to the control unit in a wired or wireless manner.

Funktionskomponenten des Anbaugerätes sind insbesondere Stellzylinder zur Veränderung der Lage des Anbaugerätes gegenüber dem Fahrgestell der Pistenraupe oder Antriebsmotoren, wie insbesondere Antriebsmotoren einer Heckfräse, um eine Ansteuerung durch Veränderung der Drehzahlen der Antriebsmotoren vorzunehmen.In a further embodiment of the invention, the control unit for activating at least one functional component of the attachment is designed in such a way that activation takes place as a function of evaluations of the measured values of the force sensors and / or the temperature sensors. Functional components of the attachment are, in particular, adjusting cylinders for changing the position of the attachment with respect to the chassis of the snow groomer or drive motors, such as, in particular, drive motors of a rear tiller, in order to control it by changing the speeds of the drive motors.

In weiterer Ausgestaltung der Erfindung ist die Steuereinheit mit wenigstens einem Peripheriegerät zur Erfassung von Geodaten der Schneefläche und/oder zur Erfassung von Umgebungsparametern, wie insbesondere einer Umgebungstemperatur und einer Luftfeuchtigkeit, gekoppelt, um eine Ansteuerung der wenigstens einen Funktionskomponente des Anbaugerätes in Abhängigkeit von einer zusätzlichen Auswertung der Umgebungsparameter und/oder der Geodaten vorzunehmen. Die zusätzlichen Daten des wenigstens einen Peripheriegerätes ermöglichen eine Referenzierung und/oder Verknüpfung dieser Daten relativ zu den Messwerten der Kraftsensorik und/oder der Temperatursensorik des Messaufnehmers, der in die Schneefläche eintaucht. Somit können insbesondere Umgebungsparameter wie Temperatur oder Luftfeuchtigkeit ergänzend herangezogen werden, um das Anbaugerät, insbesondere eine Heckfräse, anzusteuern. Geodaten sind Topografiedaten der Schneefläche und/oder der die Schneefläche tragenden Geländestruktur, die insbesondere über ein GPS-System verfügbar sind. Ein entsprechendes Peripheriegerät kann an der Pistenraupe angebracht (insbesondere bezüglich Temperatur- und Luftfeuchtigkeitserfassung) sein, oder von der Pistenraupe entfernt stationär oder mobil (Satellit, Drohne) positioniert sein.In a further embodiment of the invention, the control unit is coupled to at least one peripheral device for the acquisition of geodata of the snow surface and / or for the acquisition of environmental parameters, such as in particular an ambient temperature and air humidity, in order to activate the at least one functional component of the attachment as a function of an additional To evaluate the environmental parameters and / or the geodata. The additional data of the at least one peripheral device enables these data to be referenced and / or linked relative to the measured values of the force sensor system and / or the temperature sensor system of the measuring transducer, which is immersed in the snow surface. Thus, in particular, environmental parameters such as temperature or air humidity can be used in addition to control the attachment, in particular a rear tiller. Geodata are topographic data of the snow surface and / or the terrain structure supporting the snow surface, which are available in particular via a GPS system. A corresponding peripheral device can be attached to the snow groomer (in particular with regard to temperature and Humidity detection), or be positioned stationary or mobile (satellite, drone) away from the snowcat.

In weiterer Ausgestaltung der Erfindung taucht der wenigstens eine Messaufnehmer in seiner Messstellung in die Schneefläche auf eine Tiefe ein, die einer Bearbeitungstiefe einer Heckfräse entspricht und insbesondere aus einem Bereich von 5 cm bis 25 cm, vorzugsweise 5 cm bis 10 cm, gewählt ist. Der Messaufnehmer weist über seine Höhe, und damit in Schneetiefenrichtung, mehrere zueinander beabstandete Messaufnahmepunkte der Kraftsensorik und/oder der Temperatursensorik auf, die alle drahtlos oder drahtgebunden an die Steuereinheit angeschlossen sind.In a further embodiment of the invention, the at least one measuring sensor is immersed in its measuring position in the snow surface to a depth that corresponds to a machining depth of a rear milling machine and is selected in particular from a range of 5 cm to 25 cm, preferably 5 cm to 10 cm.

Further advantages and features of the invention emerge from the claims and from the following description of a preferred exemplary embodiment of the invention, which is illustrated with the aid of the drawings.
  • Fig. 1 shows schematically an embodiment of a snow groomer according to the invention and
  • Fig. 2 schematically a block diagram for a sensor of the snow groomer according to FIG Fig. 1 .

Eine Pistenraupe 1 nach den Fig. 1 und 2 weist ein Fahrgestell 2 auf, dem beidseitig - in Fahrzeuglängsrichtung gesehen - jeweils ein Kettenlaufwerk 3 zugeordnet ist. Die Pistenraupe 1 ist mit einem Fahrerhaus 4 versehen, das auf einer Fronthälfte des Fahrgestells 2 angeordnet ist. Dem Fahrgestell 2 sind zudem frontseitig ein Anbaugerät in Form eines Räumschildes 5 und heckseitig ein weiteres Anbaugerät in Form einer Heckfräse 6 zugeordnet. Die Heckfräse 6 ist über eine Stelleinrichtung 8 an dem Fahrgestell 2 angeordnet, die in Form eines mit mehreren hydraulischen Stellzylindern versehenen Heckgeräteträgers ausgeführt ist. Die Heckfräse 6 selbst weist ein Tragwerk auf, das lösbar an dem Heckgeräteträger gehalten ist, und in dem wenigstens eine Fräswelle sowie wenigstens ein Antriebsmotor für diese Fräswelle gehalten sind. An dem Tragwerk ist zudem eine heckseitig über eine gesamte Breite der Heckfräse 6 erstreckte Glätteinrichtung vorgesehen, die auch als Finisher bezeichnet wird. Dem Tragwerk der Heckfräse 6 sind zudem weitere Stellzylinder zugeordnet, die eine Verstellung von Teilbereichen des Tragwerks der Heckfräse 6 relativ zueinander ermöglichen.A snowcat 1 after the Fig. 1 and 2 has a chassis 2 to which a crawler gear 3 is assigned on both sides - viewed in the longitudinal direction of the vehicle. The snow groomer 1 is provided with a driver's cab 4 which is arranged on a front half of the chassis 2. The chassis 2 is also assigned an attachment in the form of a clearing blade 5 at the front and a further attachment in the form of a rear milling machine 6 at the rear. The rear milling machine 6 is arranged on the chassis 2 via an actuating device 8, which is designed in the form of a rear implement carrier provided with several hydraulic actuating cylinders. The rear milling machine 6 itself has a supporting structure which is detachably held on the rear implement carrier and in which at least one milling shaft and at least one drive motor for this milling shaft are held. In addition, a smoothing device which extends over the entire width of the rear milling machine 6 and is also referred to as a finisher is provided on the supporting structure. In addition, further adjusting cylinders are assigned to the supporting structure of the rear milling machine 6, which enable partial areas of the supporting structure of the rear milling machine 6 to be adjusted relative to one another.

Wie anhand der Fig. 1 erkennbar ist, steht die Pistenraupe 1 auf einer Schneefläche S1, S2 auf. In einem Fahrbetrieb überfährt die Pistenraupe 1 eine Oberfläche dieser Schneefläche. In einem Schneeflächenbearbeitungsmodus sind sowohl das frontseitige Räumschild 5 als auch die Heckfräse 6 aktiv und bearbeiten die Schneefläche. Mit dem Bezugszeichen S1 ist eine Schichttiefe gekennzeichnet, über die die Schneefläche durch die Heckfräse 6 bearbeitet wird. Diese Schichtdicke S1 beträgt bei der dargestellten Pistenraupe 1 etwa 10 bis 15 cm.How with the Fig. 1 can be seen, the snow groomer 1 stands on a snow surface S 1 , S 2 . In a driving mode, the snow groomer 1 drives over a surface of this snow surface. In a snow surface processing mode, both the front clearing blade 5 and the rear tiller 6 are active and process the snow surface. With the reference symbol S 1 is a Characterized layer depth over which the snow surface is processed by the rear milling machine 6. In the case of the snow groomer 1 shown, this layer thickness S 1 is approximately 10 to 15 cm.

Um einen Zustand der Schichtdicke S1 zu erfassen, der einer Arbeitstiefe der Heckfräse 6 und demzufolge einem klassischen Pistenaufbau einer Schneefläche entspricht, ist ein Messaufnehmer 7 vorgesehen, der an einem Tragwerksabschnitt der Heckfräse 6 fest angeordnet ist. Anhand der Fig. 1 ist die Positionierung des Messaufnehmers 7 in seiner Arbeitsstellung, das heißt seiner Messstellung, gezeigt, wohingegen die Heckfräse 6 in der schematischen Darstellung gemäß Fig. 1 in einer oberhalb dieser Schichtdicke S1 positionierten Lage gezeigt ist. Der Messaufnehmer 7 taucht in seiner Messstellung etwa über eine Arbeitstiefe der Heckfräse 6 in die obere Schneeschicht S1 ein.In order to detect a condition of the layer thickness S 1 that corresponds to a working depth of the rear tiller 6 and consequently a classic slope structure of a snow surface, a measuring sensor 7 is provided, which is fixedly arranged on a supporting structure section of the rear tiller 6. Based on Fig. 1 the positioning of the measuring transducer 7 in its working position, that is to say its measuring position, is shown, whereas the rear milling machine 6 is shown in the schematic representation according to FIG Fig. 1 is shown in a position positioned above this layer thickness S 1. In its measuring position, the measuring sensor 7 plunges into the upper layer of snow S 1 approximately over a working depth of the rear tiller 6.

Wie anhand der Fig. 2 erkennbar ist, weist der Messaufnehmer 7 eine Schwertform auf. Mit dem Doppelpfeil F ist die normale Fahrtrichtung der Pistenraupe 1 und damit die normale Schlepprichtung der Heckfräse 6 gezeigt. An dem Messaufnehmer 7 sind insgesamt fünf Kraftmesspunkte 101, 102, 103, 104, 105 angeordnet, die frontseitig - auf die Fahrtrichtung F bezogen - an dem Messaufnehmer 7 positioniert und in Abstand zueinander in Hochrichtung des Messaufnehmers 7 und damit in Schichttiefenrichtung, angeordnet sind. Rückseitig - ebenfalls in Fahrtrichtung F gesehen - weist der schwertförmige Messaufnehmer 7 insgesamt fünf Temperaturmesspunkte 91, 92, 93, 94, 95 auf, die in Abstand übereinander - in Hochrichtung des Messaufnehmers 7 und damit in Schichttiefenrichtung gesehen - an dem Messaufnehmer 7 befestigt sind. Die Temperaturmesspunkte 91 bis 95 sind Teil einer Temperatursensorik 9. Die Kraftmesspunkte 101 bis 105 sind Teile einer Kraftsensorik 10. Die Kraftmesspunkte 101 bis 105 und die Temperaturmesspunkte 91 bis 95 ermöglichen die Erfassung eines Härteverlaufs bzw. eines Temperaturverlaufs des Pistenaufbaus in Schichttiefenrichtung über die Schichttiefe S1. Dabei kann ein Kraftmesspunkt 101 und ein Temperaturmesspunkt 91 jeweils als Referenzmesspunkt knapp oberhalb der Schichtdicke S1 in der Messstellung des Messaufnehmers 7 positioniert sein, wie in der schematischen Darstellung gemäß Fig. 2 dargestellt.How with the Fig. 2 can be seen, the sensor 7 has a sword shape. The double arrow F shows the normal direction of travel of the snow groomer 1 and thus the normal direction in which the rear tiller 6 is towed. A total of five force measuring points 10 1 , 10 2 , 10 3 , 10 4 , 10 5 are arranged on the measuring transducer 7, which are positioned on the front side - in relation to the direction of travel F - on the measuring transducer 7 and at a distance from one another in the vertical direction of the measuring transducer 7 and thus in Layer depth direction, are arranged. On the back - also seen in the direction of travel F - the sword-shaped measuring sensor 7 has a total of five temperature measuring points 9 1 , 9 2 , 9 3 , 9 4 , 9 5 , which are spaced one above the other - viewed in the vertical direction of the measuring sensor 7 and thus in the layer depth direction - on the Sensor 7 are attached. The temperature measuring points 9 1 to 9 5 are part of a temperature sensor system 9. The force measuring points 10 1 to 10 5 are part of a force sensor system 10. The force measuring points 10 1 to 10 5 and the temperature measuring points 9 1 to 9 5 enable a hardness curve or a temperature curve to be recorded of the slope structure in the direction of the layer depth over the layer depth S 1 . A force measuring point 10 1 and a temperature measuring point 9 1 can each be positioned as a reference measuring point just above the layer thickness S 1 in the measuring position of the measuring transducer 7, as in the schematic illustration according to FIG Fig. 2 shown.

Die Kraftsensorik 10 und die Temperatursensorik 9 sind an eine elektronische Steuereinheit St angeschlossen, die aus den übermittelten Messwerten in Schneetiefenrichtung einen Härteverlauf des Pistenaufbaus über die Schichtdicke S1 sowie einen Temperaturverlauf des Pistenaufbaus über die Schichtdicke S1 ermittelt, indem unter Zuhilfenahme einer entsprechend angepassten Software die Messwerte der Kraftsensorik 10 und der Temperatursensorik 9 ausgewertet werden. Die Steuereinheit St ist zur Ausgabe der Auswertungsergebnisse an eine Anzeigeeinrichtung 11 angeschlossen, die entweder im Fahrerhaus 4 für einen Fahrer der Pistenraupe 1 zugänglich ist, oder in einem mobilen Peripheriegerät vorgesehen ist, das ebenfalls vom Fahrer der Pistenraupe 1 im Fahrerhaus 4 mitgeführt werden kann, oder das extern in Abstand zur Pistenraupe 1 gehandhabt werden kann.The force sensor system 10 and the temperature sensor system 9 are connected to an electronic control unit St, which uses the transmitted measured values in the snow depth direction to determine a hardness profile of the slope structure over the layer thickness S 1 and a temperature profile of the slope structure over the layer thickness S 1 by using appropriately adapted software the measured values of the force sensor system 10 and the temperature sensor system 9 are evaluated. The control unit St is connected to a display device 11 for outputting the evaluation results, either in the driver's cab 4 for a driver of the Snow groomer 1 is accessible, or is provided in a mobile peripheral device that can also be carried by the driver of the snow groomer 1 in the driver's cab 4, or that can be handled externally at a distance from the snow groomer 1.

Die Steuereinheit St ist auch gekoppelt mit einem Peripheriegerät 12 zur Erfassung von Umgebungsparametern wie insbesondere Außentemperatur und Luftfeuchtigkeit. Dieses Peripheriegerät 12 ist in vorteilhafter Weise an der Pistenraupe 1 angebracht. Zudem empfängt die Steuereinheit St Daten eines Peripheriegerätes zur Erfassung von Geodaten einer Schneeoberfläche, die die Pistenraupe 1 überfahren soll. Diese Geodaten können über ein GPS-System 13 an die Steuereinheit St übermittelt werden. Alternativ können entsprechende Geodaten über die Topografie der zu überfahrenden Schneefläche auch über andere Datenverarbeitungssysteme der Steuereinheit St zugeführt werden, in denen entsprechende Topografiedaten abgelegt sind. Die Steuereinheit St wertet die Daten der Peripheriegeräte 12 und 13 wie auch die Messwerte der Kraftsensorik 10 und der Temperatursensorik 9 aus, um hiervon abhängig hydraulische Stellzylinder der Stelleinrichtung 8 und/oder der Heckfräse 6 und/oder Antriebsmotoren der Heckfräse 6 anzusteuern. Anhand der Fig. 2 sind diese Ansteuerungsobjekte in Form der Stellzylinder oder Antriebsmotoren mit dem Bezugszeichen A versehen.The control unit St is also coupled to a peripheral device 12 for recording environmental parameters such as, in particular, outside temperature and air humidity. This peripheral device 12 is advantageously attached to the snow groomer 1. In addition, the control unit St receives data from a peripheral device for recording geodata of a snow surface that the snow groomer 1 is to drive over. These geodata can be transmitted to the control unit St via a GPS system 13. Alternatively, corresponding geodata about the topography of the snow surface to be driven over can also be fed to the control unit St via other data processing systems, in which corresponding topography data are stored. The control unit St evaluates the data of the peripheral devices 12 and 13 as well as the measured values of the force sensors 10 and the temperature sensors 9 in order to control hydraulic actuating cylinders of the actuating device 8 and / or the rear milling machine 6 and / or drive motors of the rear milling machine 6 as a function of this. Based on Fig. 2 these control objects in the form of the actuating cylinders or drive motors are provided with the reference symbol A.

Je nachdem, wie der Härteverlauf und der Temperaturverlauf der Schneeflächenschicht S1, der der Arbeitstiefe der Heckfräse 6 entspricht, erfasst ist, kann die Heckfräse 6 bezüglich der einzustellenden Arbeitstiefe für die Fräswellen und bezüglich der Drehzahlen der Fräsmotoren der Fräswellen in geeigneter Weise angepasst werden.Depending on how the hardness profile and the temperature profile of the snow surface layer S 1 , which corresponds to the working depth of the rear tiller 6, is recorded, the rear tiller 6 can be adapted in a suitable manner with regard to the working depth to be set for the milling shafts and with regard to the speeds of the milling motors of the milling shafts.
