Description

Die Erfindung betrifft ein Flurförderzeug mit einer Anzeige- und Bedienvorrichtung. Insbesondere betrifft die Erfindung ein Flurförderzeug nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a truck with a display and control device. In particular, the invention relates to an industrial truck according to the preamble of patent claim 1.

Flurförderzeuge, beispielsweise Gabelstapler mit den Funktionen eines Hubmastes, weisen eine Vielzahl von Arbeitsfunktionen auf, die über verschiedene Bedienelemente von einer Bedienperson gesteuert werden. Hinzu kommen die Steuerungsfunktionen für das Fahren. Neben der direkten Ansteuerung dieser Arbeitsfunktionen und Fahrfunktionen besteht auch eine zunehmende Anzahl von Einstellmöglichkeiten. Bei diesen kann es sich um klassische Funktion eines Fahrzeuges handeln, wie Lichtschalter, Scheibenwischer, aber auch um komplexere Einstellungen, die sich auf das Fahrverhalten auswirken, wie insbesondere bei Flurförderzeugen Rangierfunktionen, durch die Geschwindigkeiten herabgesetzt werden und eine feinfühligere Steuerung möglich ist. Hinzu kommen Komfortfunktionen wie etwa eine Klimatisierung, Belüftung und Beheizung der Kabine, die weitere zahlreiche Einstellmöglichkeiten erfordert. Dabei kann man unterscheiden zwischen primären Funktionen und Sekundärfunktionen, wobei Letztere solche sind, bei denen eine Einstellung oder Betätigung der entsprechenden Funktionen nicht kontinuierlich beim Arbeiten mit dem Flurförderzeug erforderlich ist. Da ein Flurförderzeug nicht regelmäßig im öffentlichen Straßenverkehr bewegt wird und oftmals nur im Inneren von Industriehallen, können zu solchen sekundären Funktionen abhängig von der Art des Einsatzes des Flurförderzeugs auch beispielsweise Lichtschalter und Schalter für Scheibenwischer gerechnet werden. Auch diese müssen unter Umständen nur im Ausnahmefall betätigt werden, wenn beispielsweise nur sehr selten innerhalb eines Betriebsgeländes auf ein Freigelände gefahren wird. Ein weiteres Beispiel solcher nur seltener vorzunehmenden Einstellungen bzw. sekundärer Funktionen sind Einstellungen von Assistenzsystemen, die Anpassungen an Wünsche der Bedienperson zulassen, beispielsweise Einstellungen zu dem Verhalten einer Hubhöhenvorwahl. Generell kann man als sekundäre Funktionen zumindest auch solche Einstellungsmöglichkeiten ansehen, die für eine Vielzahl von nachfolgenden, wiederholten Steuerungsbetätigungen vorgenommen werden.Forklifts, such as forklifts with the functions of a lift mast, have a variety of work functions, which are controlled via various controls by an operator. Added to this are the control functions for driving. In addition to the direct control of these work functions and driving functions, there is also an increasing number of setting options. These may be a classic function of a vehicle, such as light switches, windshield wipers, but also more complex settings that have an effect on driving behavior, such as in particular for industrial trucks shunting functions, are reduced by the speeds and a more sensitive control is possible. In addition, there are comfort functions such as air conditioning, ventilation and heating of the cabin, which requires numerous other adjustment options. It can be distinguished between primary functions and secondary functions, the latter being those in which an adjustment or actuation of the corresponding functions is not required continuously when working with the truck. Since a truck is not regularly moved on public roads and often only in the interior of industrial halls, such secondary functions can be expected depending on the type of use of the truck, for example, light switch and switch for windshield wipers. These may have to be operated only in exceptional cases, for example, if, for example, is rarely driven within a site on an open area. Another example of such settings or secondary functions to be made less frequently are settings of assistance systems which permit adjustments to the wishes of the operator, for example settings for the behavior of a stroke height preselection. Generally, as secondary functions, one can at least also regard those setting options that are suitable for a large number of subsequent, repeated control operations.

Bekannt sind bei Flurförderzeugen ganz allgemein als Bedienelemente diskrete Schalter, Folientasten, aber auch Schaltflächen beispielsweise auf einem Touchscreen. Weiterhin im Stande Technik bekannt sind an einem Lenkrad angeordnete Lenkstockschalter.Are known in industrial vehicles in general as controls discrete switches, membrane keys, but also buttons, for example, on a touch screen. Furthermore, known in the art are arranged on a steering wheel steering column switch.

Bekannt sind auch optische Anzeigevorrichtung, insbesondere Bildschirme.Also known optical display device, in particular screens.

Als Problem stellt sich dabei gerade bei Flurförderzeugen heraus, dass nur beschränkter Platz vorhanden ist und eine Vielzahl solcher Schalt- und Einstellmöglichkeiten nicht ohne weiteres unterzubringen ist. Auch erweist es sich in der Herstellung als problematisch, für eine Vielzahl von Varianten und unterschiedlichen Ausführungsmöglichkeiten eines Flurförderzeugs jeweils angepasste Schalter und Bedienelemente vorzusehen. Gerade bei Flurförderzeugen ergibt sich jedoch zunehmend eine Vielzahl von Varianten aufgrund der Anpassung an spezielle Einsatzbedingungen und jeweils eine unterschiedliche Ausstattung mit Zusatzgeräten sowie Arbeitsfunktionen.As a problem, it turns out just in industrial trucks that only limited space is available and a variety of such switching and adjustment is not readily accommodate. Also, it proves to be problematic in manufacturing to provide for a variety of variants and different design options for a truck each adapted switches and controls. Especially for industrial trucks, however, there is an increasing number of variants due to the adaptation to special conditions of use and in each case a different equipment with additional equipment and work functions.

Aus der DE 100 15 009 A1 ist ein Steuerungs- und Überwachungssystem für ein Flurförderzeug bekannt, bei dem Funktionsgruppen in sinnfälligen Menüs angeordnet werden.From the DE 100 15 009 A1 a control and monitoring system for a truck is known, are arranged in the functional groups in meaningful menus.

DE 100 15 009 offenbart den Oberbegriff des Anspruchs 1. DE 100 15 009 discloses the preamble of claim 1.

Die JP H05 286 700 A offenbart eine Anzeigevorrichtung eines Gabelstaplers, die zwischen einem Ladebetrieb und einem Fahrbetrieb umgeschaltet werden kann.The JP H05 286 700 A discloses a display device of a forklift which can be switched between a loading operation and a driving operation.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Flurförderzeug mit einer Bedien- und Anzeigevorrichtung zur Verfügung zu stellen, das die zuvor genannten Nachteile vermeidet und mit dem mit wenig Platzaufwand eine Bedienung aller Funktionen möglich ist.The present invention has for its object to provide an industrial truck with an operating and display device that avoids the aforementioned disadvantages and with the use of all functions is possible with little space.

Diese Aufgabe wird durch ein Flurförderzeug mit den Merkmalen des unabhängigen Patentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by a truck with the features of independent claim 1. Advantageous developments of the invention are specified in the subclaims.

Die Aufgabe wird dadurch gelöst, dass bei einem Flurförderzeug mit einem Steuerungsrechner zur Ansteuerung von Fahr- und Arbeitsfunktionen sowie mit mindestens einer Anzeige- und Bedienvorrichtung, die zur Anzeige von Informationen zu den Fahr-und Arbeitsfunktionen durch den Steuerungsrechner einen Bildschirm aufweist und mit Schaltelementen, die mit dem Bildschirm verknüpft sind und durch die Eingaben erfolgen können, die Schaltelemente dem Rand des Bildschirms und jeweils einer Symbol- und/oder Textanzeige für eine Unterauswahl am Rand des Bildschirms zugeordnet sind, so dass bei Betätigung des Schaltelements die Unterauswahl zur Steuerung sekundärer Funktionen mit weiteren Eingabemöglichkeiten auf dem Bildschirm angezeigt wird. Erfindungsgemäß umfassen die sekundären Funktionen die Ansteuerung einer Beleuchtung des Flurförderzeugs und/oder Funktionen von Scheibenwischern und/oder Steuerungsfunktionen einer Heizung und/oder Steuerungsfunktionen einer Klimatisierung.The object is achieved in that in a truck with a control computer for controlling driving and working functions and with at least one display and control device which has a screen for displaying information about the driving and working functions by the control computer and switching elements, which are associated with the screen and can be made by the inputs, the switching elements are assigned to the edge of the screen and each a symbol and / or text display for a sub-selection at the edge of the screen, so that when actuated the switching element, the sub-selection for controlling secondary functions with further input options on the screen is displayed. According to the invention, the secondary functions include the control of a lighting of the truck and / or functions of windscreen wipers and / or control functions of a heating and / or control functions of air conditioning.

Vorteilhaft können dadurch sehr viele Funktionen bei geringem Platzbedarf angesteuert werden. Auch wird die Herstellung des Flurförderzeugs stark vereinfacht, da für eine Vielzahl von Varianten und unterschiedlichen Ausführungen des Flurförderzeugs jeweils angepasste Schalter und Bedienelemente leicht vorgesehen werden können. Die Varianz in der Montage beschränkt sich auf das Aktivieren bestimmter Funktionen in der Fahrzeugsoftware. Es muss nicht für jede Funktion, die durch eine Ausführungsform neu hinzukommt, ein bestimmter Schalter am Montageband vorgehalten werden. Auch können spätere Anpassungen und nachträgliche Ausrüstungen mit zusätzlichen Geräten bei dem Flurförderzeug leicht berücksichtigt werden. Indem die wichtigsten Funktionen aktuell auf der Bildschirmoberfläche dargestellt werden und durch das Aufrufen von einer Unterauswahl die sekundären Funktionen zugänglich werden, ergibt sich eine intuitive und leichte Bedienung. Es können in solchen Unterauswahlen auch Funktionen von Geräten von Drittanbietern integriert werden. Die Schaltelemente können dabei als mechanische Schalter seitlich neben dem Bildschirm angeordnet sein, oder als Schaltfläche auf dem Bildschirm selbst angeordnet sein, wenn dieser ein Touchscreen ist. Dies ist auch in Kombination möglich. In einer Unterauswahl kann eine weitere Unterauswahl angeboten werden. Bei den Symbol- und/oder Textanzeigen sind Kombinationen aus reinen Symbolen mit Texthinweisen denkbar. Durch diese Anzeigen wird für die Bedienperson verdeutlicht, was durch das Schaltelement ausgewählt werden kann. Der einfachste Fall und am schnellsten zu erfassen sind hierfür Symbole im Sinne von einfachen Grafiken.Advantageously, very many functions can be controlled in a small footprint. Also, the production of the truck is greatly simplified, since for a variety of variants and different versions of the truck each adapted switches and controls can be easily provided. The variance in the assembly is limited to activating certain functions in the vehicle software. It is not necessary for every function, which is added by an embodiment, a specific switch on the assembly line be kept. Also later adjustments and subsequent equipment with additional equipment in the truck can be easily taken into account. By presenting the most important functions currently on the screen surface and by accessing a subselection, the secondary functions are accessible, resulting in an intuitive and easy operation. It is also possible to integrate functions of third-party devices in such sub-selections. The switching elements can be arranged as a mechanical switch laterally next to the screen, or be arranged as a button on the screen itself, if this is a touch screen. This is possible in combination. In a subselection another subselection can be offered. For the symbol and / or text displays, combinations of pure symbols with text hints are conceivable. These displays make it clear to the operator what can be selected by the switching element. The simplest case and the fastest to capture for this purpose symbols in the sense of simple graphics.

Vorteilhaft sind die Schaltelemente neben dem Bildschirmrand angeordnet.Advantageously, the switching elements are arranged next to the edge of the screen.

Außerhalb des Bildschirms und direkt am Rand des Bildschirms können die Schaltelemente als mechanische Schalter ausgeführt sein, aber auch als Berührungssensoren.Outside of the screen and directly at the edge of the screen, the switching elements can be designed as mechanical switches, but also as touch sensors.

In einer vorteilhaften Ausgestaltung ist der Bildschirm ein Touchscreen und sind die Schaltelemente Schaltflächen.In an advantageous embodiment, the screen is a touch screen and the switching elements are buttons.

Die Symbol- und/oder Textanzeigen können zugleich die Schaltelemente sein.The symbol and / or text displays can also be the switching elements.

Die Schaltelemente können am linken Rand des Bildschirms angeordnet sein.The switching elements can be arranged on the left edge of the screen.

Die Schaltelemente können am rechten Rand des Bildschirms angeordnet sein.The switching elements can be arranged on the right edge of the screen.

Vor allem bei einer Anordnung des Bildschirms seitlich rechts vor einem Fahrersitz, beispielsweise befestigt an einer Armlehne, wird vorteilhaft eine Sichtbehinderung vermieden während der Betätigung der Schaltelemente. Durch die Anordnung der Schaltelemente am rechten, senkrechten Bildschirmrand, wird der Bildschirm bei einer Betätigung nicht durch den Arm einer Bedienperson verdeckt.Especially with an arrangement of the screen laterally right in front of a driver's seat, for example, attached to an armrest, a visual obstruction is advantageously avoided during the operation of the switching elements. The arrangement of the switching elements on the right, vertical edge of the screen, the screen is not covered by an operator's arm when actuated.

Vorteilhaft sind die Schaltelemente und der Bildschirm rechts vor einem Fahrersitz angeordnet.Advantageously, the switching elements and the screen are arranged right in front of a driver's seat.

Die Schaltelemente und der Bildschirm können am vorderen Ende einer Armlehne des Fahrersitzes befestigt sein.The switching elements and the screen may be attached to the front end of an armrest of the driver's seat.

Vorteilhaft umfassen die sekundären Funktionen die Ansteuerung von Einstellungen zum Fahrbetrieb.Advantageously, the secondary functions include the activation of settings for driving operation.

In günstiger Ausgestaltung umfassen die sekundäre Funktionen Einstellungen zu Assistenzfunktionen, wie etwa einer Hubhöhenvorwahl, einer automatisierten Ein-/Auslagerungsfunktion, und/oder einer Fahrzeugnavigation.In a favorable embodiment, the secondary functions include settings for assistance functions, such as a lift height preselection, an automated load / unload function, and / or a vehicle navigation.

Weitere Vorteile und Einzelheiten der Erfindung werden anhand des in der schematischen Figur dargestellten Ausführungsbeispiels näher erläutert. Hierbei zeigt die Figur einen Bildschirm 1 einer Bedien- und Anzeigevorrichtung 2 sowie an der rechten Seite angeordnete Schaltelemente 3 und an der linken Seite des Bildschirms 1 angeordnete Schaltelemente 3. Symbol- und/oder Textanzeigen 4 für eine Unterauswahl sind in dem vorliegenden Ausführungsbeispiel als reine Symbole gestaltet und jeweils zugeordnet zu den Schaltelementen 3 am rechten senkrechten Rand des Bildschirms 1 und linken senkrechten Rand des Bildschirms 1 angeordnet. Wenn ein Schaltelement 3 durch eine Bedienperson betätigt wird, so zeigt der Steuerungsrechner auf dem Bildschirm 1 eine Unterauswahl an, in der Einstellungen für sekundäre Funktionen vorgenommen werden können.Further advantages and details of the invention will be explained in more detail with reference to the embodiment shown in the schematic figure. Here, the figure shows a screen 1 of a control and display device 2 and disposed on the right side switching elements 3 and arranged on the left side of the screen 1 switching elements 3. Symbol and / or text displays 4 for a subselection are in the present embodiment as a pure Symbols designed and each assigned to the switching elements 3 on the right vertical edge of the screen 1 and left vertical edge of the screen 1 is arranged. When a switching element 3 is operated by an operator, the control computer displays on the screen 1 a subselection in which settings for secondary functions can be made.
