Definitions

  • the invention relates to an industrial truck with a mast, a driver's canopy with a driver's workplace for a driver and a vehicle body according to the preamble of patent claim 1.
  • a rear vehicle contour ie a rear area of an industrial truck that has a trailer hitch
  • this rear vehicle contour is covered by the counterweight of the industrial truck.
  • Other critical areas that are not directly visible to the driver from his driver's workplace and are in the immediate vicinity of the industrial truck are, for example, the front wheels of the vehicle, which are covered by fenders, the fork carriage, the tips of the fork arms, which are attached to the Fork carriage are arranged, or side areas of the vehicle.
  • Obstacles or objects that cross the path of the industrial truck or that are located in one of the above-mentioned surrounding areas that are difficult or not directly visible to the driver can therefore often not be recognized by the driver in good time or only too late.
  • the risk of a collision due to a delay in braking by the driver of the industrial truck, even if the driving style is adapted, cannot be completely ruled out.
  • Solutions known in the prior art often provide for the use of sensors which are intended to warn the driver in good time of an imminent collision of the industrial truck he is steering with an object or obstacle.
  • the subsequent installation of such sensors in existing industrial trucks is often associated with additional technical and thus financial expenditure.
  • the use of such sensors does not improve the driver's direct or immediate view of these critical environmental areas in the vicinity of the industrial truck.
  • the driver's poor or insufficient view of critical areas from his driver's workplace of the industrial truck therefore results not only in possible collisions with objects in these areas but also damage to the vehicle itself, the environment and the load to be transported.
  • the driver often has to drive slowly and particularly carefully because potential collision points in these critical surrounding areas are not directly visible to him. This reduces the goods handling performance and leads to an increase in costs for the operator of the vehicle.
  • the EP 0 254 192 A1 discloses an industrial truck in which cameras record images of areas hidden from the driver's field of vision, which are displayed to the driver of the industrial truck on one or more monitors. Two cameras can be arranged at the same height and at a distance from one another, so that the distance of an object can be calculated in a computer by virtual overlapping of the two camera images and this calculated distance can be displayed to the driver.
  • the EP 0 254 192 A1 discloses the preamble of claim 1.
  • the JP 2015 174705 A discloses an industrial truck in which a camera is arranged so that it can pivot about a pivot axis and pivots as a function of the lifting height of the forks, so that the camera is directed at the forks at every lifting height.
  • the camera image supplied by the camera is overlaid with a virtual and stored fork image and an image composed of camera image A and the virtual fork image B is shown to the driver on a head-up display.
  • the UK 2 460 326 A1 discloses an industrial truck that can be remotely controlled with a mobile device.
  • the mobile device has a display on which the operating elements of the industrial truck can be shown.
  • the industrial truck can have a camera whose camera images can be shown on the display of the mobile device.
  • the present invention is therefore based on the object of further developing an industrial truck in such a way that a driver in his driver's workplace of the industrial truck has a direct and therefore unrestricted view of the surrounding areas in the vicinity of the industrial truck, which are otherwise covered for him or are very difficult to see.
  • Another task is to reduce the risk of the industrial truck colliding in areas that are difficult to see and thus avoid damage to the vehicle, the surroundings and the load to be transported.
  • the industrial truck is provided with a mast, a driver's canopy with a driver's workplace for a driver and a vehicle body, and includes a display device and a recording device for recording an image of an area covered by the industrial truck, which is covered by the driver's workplace cannot be seen immediately or directly by the driver present, with the display device being able to be electronically connected to the recording device and with the display device also being designed to display the surrounding area recorded by the recording device in such a way that a virtual viewing channel can be generated through the industrial truck, through which the Drivers located in the driver's workplace is enabled to look into the surrounding area covered by the industrial truck, with the direction of the virtual viewing channel is essentially congruent with the direction in which the driver is looking at the surrounding area covered by the industrial truck, and an image processing device is provided which is designed to convert the image of the surrounding area recorded by the recording device for the driver in the overhead guard from a perspective specific to the recording device into a to convert driver-specific perspective for the driver located in the overhead guard,

Description

Die Erfindung betrifft ein Flurförderzeug mit einem Hubgerüst, einem Fahrerschutzdach mit einem Fahrerarbeitsplatz für einen Fahrer und einem Fahrzeugkörper gemäß Oberbegriff des Patentanspruchs 1.The invention relates to an industrial truck with a mast, a driver's canopy with a driver's workplace for a driver and a vehicle body according to the preamble of patent claim 1.

Flurförderzeuge sind mit ihrem Hubgerüst dazu ausgelegt, Lasten zu transportieren. Das Hubgerüst und ein Lastaufnahmemittel des Hubgerüsts sowie eine gegebenenfalls mit dem Hubgerüst aufgenommene Last führen jedoch zu Einschränkungen der Sicht des im Fahrerarbeitsplatz befindlichen Fahrers, da das Hubgerüst bzw. das Lastaufnahmemittel und eine gegebenenfalls aufgenommene Last einem Fahrer, der für gewöhnlich an seinem Fahrerarbeitsplatz sitzt und welcher sich in der Regel unmittelbar hinter dem Hubgerüst und dem Lastaufnahmemittel befindet, eine freie und direkte Sicht auf dem vor dem Fahrzeug liegenden Fahrweg oder den zu fahrenden Transportweg nehmen oder zumindest stark einschränken, auf welchem sich das Flurförderzeug entlangbewegt. Zusätzlich gibt es aus der Perspektive des Fahrers von seinem Fahrerarbeitsplatz aus betrachtet, Umgebungsbereiche, die sich in einer unmittelbaren Nähe des Flurförderzeugs befinden und die für diesen Fahrer nur schwer oder gar nicht direkt einsehbar sind. Neben diesen schwer einsehbaren Umgebungsbereichen sind es aber auch Teile der Fahrzeugkontur des Flurförderzeugs selbst, die für den Fahrer auf seinem Fahrerarbeitsplatz nicht direkt einsehbar sind, weil diese durch Komponenten des Fahrerschutzdaches oder des Fahrzeugs verdeckt werden.Industrial trucks are designed with their mast to transport loads. However, the mast and a load-carrying device of the mast and any load picked up by the mast lead to restrictions in the driver's view located in the driver's workplace, since the mast or the load-carrying device and any load picked up by a driver who usually sits at his driver's workplace and which is usually located immediately behind the mast and the load handling device, take away or at least severely restrict a free and direct view of the route in front of the vehicle or the transport route to be traveled along which the industrial truck is moving. In addition, from the perspective of the driver from his driver's workplace, there are surrounding areas that are in the immediate vicinity of the industrial truck and that are difficult or impossible for the driver to see directly. In addition to these surrounding areas that are difficult to see, there are also parts of the vehicle contour of the industrial truck itself that the driver cannot see directly from his driver's workplace because they are covered by components of the driver's overhead guard or the vehicle.

So lässt sich zum Beispiel eine hintere Fahrzeugkontur, also ein Heckbereich eines Flurförderzeugs, welche über eine Anhängerkupplung verfügt, von einem Fahrer nicht direkt einsehen, da diese hintere Fahrzeugkontur von dem Gegengewicht des Flurförderzeugs verdeckt ist. Andere kritische Umgebungsbereiche, die für den Fahrer auf seinem Fahrerarbeitsplatz nicht direkt einsehbar sind und sich in der unmittelbaren Nähe des Flurförderzeugs befinden, sind zum Beispiel die Vorderräder des Fahrzeugs, die durch Kotflügel verdeckt sein, der Gabelträger, die Spitzen vom Gabelzinken, die an dem Gabelträger angeordnet sind, oder Seitenbereiche des Fahrzeugs.For example, a rear vehicle contour, ie a rear area of an industrial truck that has a trailer hitch, cannot be seen directly by a driver because this rear vehicle contour is covered by the counterweight of the industrial truck. Other critical areas that are not directly visible to the driver from his driver's workplace and are in the immediate vicinity of the industrial truck are, for example, the front wheels of the vehicle, which are covered by fenders, the fork carriage, the tips of the fork arms, which are attached to the Fork carriage are arranged, or side areas of the vehicle.

Hindernisse oder Objekte, die den Weg des Flurförderzeugs kreuzen oder die sich in einem der zuvor genannten für den Fahrer schwer oder nicht direkt einsehbaren Umgebungsbereich befinden, können deshalb von dem Fahrer oftmals nicht rechtzeitig oder nur spät erkannt werden. Die Gefahr einer Kollision aufgrund eines verspätet eingeleiteten Abbremsmanövers durch den Fahrer des Flurförderzeugs, selbst bei einer angepassten Fahrweise, lässt sich deshalb nicht völlig ausschließen.Obstacles or objects that cross the path of the industrial truck or that are located in one of the above-mentioned surrounding areas that are difficult or not directly visible to the driver can therefore often not be recognized by the driver in good time or only too late. The risk of a collision due to a delay in braking by the driver of the industrial truck, even if the driving style is adapted, cannot be completely ruled out.

Im Stand der Technik bekannte Lösungen sehen oftmals den Einsatz von Sensoren vor, die den Fahrer bei einer bevorstehenden Kollision des von ihm gelenkten Flurförderzeugs mit einem Objekt oder Hindernis rechtzeitig warnen sollen. Der nachträgliche Einbau derartiger Sensoren in bestehende Flurförderzeuge ist jedoch oftmals mit einem technischen und damit finanziellen Mehraufwand verbunden. Zudem verbessert der Einsatz derartiger Sensoren nicht die direkte oder unmittelbare Sicht des Fahrers auf diese kritischen Umgebungsbereiche in der Nähe des Flurförderzeugs. Die schlechte oder unzureichende Sicht des Fahrers von seinem Fahrerarbeitsplatz des Flurförderzeugs auf kritische Umgebungsbereiche hat deshalb neben möglichen Kollisionen mit Objekten in diesen Umgebungsbereichen auch Schäden für das Fahrzeug selbst, der Umgebung und der zu transportierenden Ladung zur Folge. Außerdem muss der Fahrer häufig langsam und besonders vorsichtig fahren, weil potentielle Kollisionsstellen in diesen kritischen Umgebungsbereichen von diesem nicht direkt einsehbar sind. Dies reduziert die Warenumschlagsleistung und führt zu einer Kostenerhöhung bei dem Betreiber des Fahrzeugs.Solutions known in the prior art often provide for the use of sensors which are intended to warn the driver in good time of an imminent collision of the industrial truck he is steering with an object or obstacle. However, the subsequent installation of such sensors in existing industrial trucks is often associated with additional technical and thus financial expenditure. In addition, the use of such sensors does not improve the driver's direct or immediate view of these critical environmental areas in the vicinity of the industrial truck. The driver's poor or insufficient view of critical areas from his driver's workplace of the industrial truck therefore results not only in possible collisions with objects in these areas but also damage to the vehicle itself, the environment and the load to be transported. In addition, the driver often has to drive slowly and particularly carefully because potential collision points in these critical surrounding areas are not directly visible to him. This reduces the goods handling performance and leads to an increase in costs for the operator of the vehicle.

Die GB 2 460 326 A1 offenbart ein Flurförderzeug, das mit einem mobilen Gerät ferngesteuert werden kann. Das mobile Gerät hat ein Display, auf dem die Bedienelemente des Flurförderzeugs dargestellt werden können. Das Flurförderzeug kann eine Kamera aufweisen, deren Kamerabilder auf dem Display des mobilen Geräts dargestellt werden können.the UK 2 460 326 A1 discloses an industrial truck that can be remotely controlled with a mobile device. The mobile device has a display on which the operating elements of the industrial truck can be shown. The industrial truck can have a camera whose camera images can be shown on the display of the mobile device.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, ein Flurförderzeug derart weiterzubilden, dass ein Fahrer auf seinem Fahrerarbeitsplatz des Flurförderzeugs eine direkte und damit uneingeschränkte Sicht auf Umgebungsbereiche in der Nähe des Flurförderzeugs erhält, die für ihn sonst verdeckt oder nur sehr schwer einsehbar sind. Eine weitere Aufgabe besteht außerdem darin, die Gefahr von Kollisionen des Flurförderzeugs in schwer einsehbaren Umgebungsbereichen zu reduzieren und damit Schäden für das Fahrzeug, die Umgebung und die zu transportierende Last zu vermeiden.The present invention is therefore based on the object of further developing an industrial truck in such a way that a driver in his driver's workplace of the industrial truck has a direct and therefore unrestricted view of the surrounding areas in the vicinity of the industrial truck, which are otherwise covered for him or are very difficult to see. Another task is to reduce the risk of the industrial truck colliding in areas that are difficult to see and thus avoid damage to the vehicle, the surroundings and the load to be transported.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Flurförderzeug mit einem Hubgerüst, einem Fahrerschutzdach mit einem Fahrerarbeitsplatz für einen Fahrer und einem Fahrzeugkörper versehen ist und eine Anzeigevorrichtung und eine Aufnahmevorrichtung zur Aufnahme eines Abbildes eines von dem Flurförderzeug verdeckten Umgebungsbereiches umfasst, der von dem am Fahrerarbeitsplatz befindlichen Fahrer nicht unmittelbar oder direkt einsehbar ist, wobei die Anzeigevorrichtung mit der Aufnahmevorrichtung elektronisch verbindbar ist und wobei die Anzeigevorrichtung ferner ausgebildet ist, den von der Aufnahmevorrichtung aufgenommenen Umgebungsbereich derart anzuzeigen, dass ein virtueller Sichtkanal durch das Flurförderzeug hindurch erzeugbar ist, durch welchen es dem im Fahrerarbeitsplatz befindlichen Fahrer ermöglicht wird, in dem von dem Flurförderzeug verdeckten Umgebungsbereich zu blicken, wobei die Richtung des virtuellen Sichtkanals im Wesentlichen deckungsgleich zu der Blickrichtung des Fahrers auf den von dem Flurförderzeug verdeckten Umgebungsbereich ist und wobei eine Bildverarbeitungseinrichtung vorgesehen ist, welche ausgebildet ist, das von der Aufnahmevorrichtung aufgenommenes Abbild des Umgebungsbereiches für den im Fahrerschutzdach befindlichen Fahrer von einer der Aufnahmevorrichtung spezifischen Perspektive in eine für den im Fahrerschutzdach befindlichen Fahrer fahrerspezifischen Perspektive umzurechnen, welche in der Anzeigevorrichtung dargestellt wird.This object is achieved according to the invention in that the industrial truck is provided with a mast, a driver's canopy with a driver's workplace for a driver and a vehicle body, and includes a display device and a recording device for recording an image of an area covered by the industrial truck, which is covered by the driver's workplace cannot be seen immediately or directly by the driver present, with the display device being able to be electronically connected to the recording device and with the display device also being designed to display the surrounding area recorded by the recording device in such a way that a virtual viewing channel can be generated through the industrial truck, through which the Drivers located in the driver's workplace is enabled to look into the surrounding area covered by the industrial truck, with the direction of the virtual viewing channel is essentially congruent with the direction in which the driver is looking at the surrounding area covered by the industrial truck, and an image processing device is provided which is designed to convert the image of the surrounding area recorded by the recording device for the driver in the overhead guard from a perspective specific to the recording device into a to convert driver-specific perspective for the driver located in the overhead guard, which is displayed in the display device.

Der erfindungsgemäße Gedanke der vorliegenden Erfindung besteht darin, dass das erfindungsgemäßen Flurförderzeug eine Aufnahmevorrichtung umfasst, welche ein Abbild eines von dem Flurförderzeugs verdeckten Umgebungsbereiches aufnimmt und wobei dieses aufgenommene Abbild auf einer Anzeigevorrichtung für einen Fahrer im Fahrerarbeitsplatz derart angezeigt wird, dass dadurch ein virtueller Sichtkanal für den Fahrer erzeugt wird. Durch diesen virtuellen Sichtkanal wird bei dem Fahrer der Eindruck erzeugt, als würde er von seinem Fahrerarbeitssitzplatz aus eine direkte Sicht auf den eigentlichen verdeckten Umgebungsbereich haben.The idea of the present invention according to the invention is that the industrial truck according to the invention comprises a recording device which records an image of a surrounding area covered by the industrial truck and this recorded image is displayed on a display device for a driver in the driver's workplace in such a way that a virtual visual channel is created for the driver is generated. This virtual viewing channel gives the driver the impression that he would have a direct view of the actual covered area from his driver's seat.

Durch das erfindungsgemäße Flurförderzeug wird der Vorteil erzielt, dass der Fahrer auf seinem Fahrerarbeitsplatz des Flurförderzeugs mit Hilfe des erzeugten virtuellen Sichtkanals einen für ihn aus seiner Fahrerperspektive schwer oder gar nicht direkt einsehbaren Umgebungsbereich direkt einsehen kann. Dadurch können Kollisionen des Fahrzeugs mit in diesem bislang nur schwer einsehbaren Umgebungsbereich befindlichen Objekten deutlich reduziert werden.The industrial truck according to the invention achieves the advantage that the driver at his driver's workplace of the industrial truck can use the generated virtual viewing channel to directly see a surrounding area that is difficult or impossible to see directly from his driver's perspective. As a result, collisions of the vehicle with objects located in this surrounding area, which was previously difficult to see, can be significantly reduced.

Ein weiterer Vorteil des erfindungsgemäßen Flurförderzeugs besteht darin, dass die Belastung des Fahrers bei dem Betrieb des Flurförderzeugs reduziert wird, da dieser durch eine nun verbesserte Sicht auf mögliche Kollisionsstellen in kritischen Umgebungsbereiche in der Nähe des Flurförderzeugs entspannter arbeiten kann und weniger Angst vor Unfällen haben muss. Auch unter ergonomischen Gesichtspunkten wird der Fahrer des erfindungsgemäßen Flurförderzeugs entlastet, da sich dieser für eine verbesserte Sicht auf mögliche Kollisionsstellen nicht mehr in eine unnatürliche und für seinen Körper belastende Sitz- oder Halteposition für den Betrieb des Flurförderzeugs zu begeben braucht.A further advantage of the industrial truck according to the invention is that the stress on the driver when operating the industrial truck is reduced, since he can work in a more relaxed manner thanks to a now improved view of possible collision points in critical surrounding areas near the industrial truck and has less fear of accidents . The driver of the industrial truck according to the invention is also relieved from an ergonomic point of view, since he no longer needs to go into an unnatural sitting or holding position that puts a strain on his body to operate the industrial truck for an improved view of possible collision points.

Ein weiterer Vorteil des erfindungsgemäßen Flurförderzeugs besteht darin, dass ein Fahrer Transportaufträge in einer schnelleren Zeit und effektiver abwickeln kann, denn da er aus der Perspektive seines Fahrerarbeitsplatzes bislang verdeckte Umgebungsbereiche in der Nähe seines Fahrzeugs nun direkt über den virtuellen Sichtkanal einsehen kann, muss er das Fahrzeug nicht langsamer als erforderlich bewegen.A further advantage of the industrial truck according to the invention is that a driver can process transport orders more quickly and more effectively, because from the perspective of his driver's workplace he can now see previously hidden areas in the vicinity of his vehicle directly via the virtual viewing channel, he has to Do not move the vehicle slower than necessary.

Gemäß der vorliegenden Erfindung ist die Richtung des virtuellen Sichtkanals im Wesentlichen deckungsgleich zu der Blickrichtung des Fahrers auf den Umgebungsbereich. Dadurch wird der Vorteil erreicht, dass der Fahrer direkt auf einen verdeckten Sichtbereich, der auch als Umgebungsbereich bezeichnet wird, blicken kann, ohne dass der Fahrer - auch und insbesondere während des Fahrzeugbetriebes - eine unnatürliche Position oder Körperhaltung innerhalb seines Fahrerarbeitsplatzes einnehmen muss, um eine für ihn gute Sicht auf den ihn interessierenden Umgebungsbereich in der Nähe des Flurförderzeugs zu erhalten. Bei dem erfindungsgemäßen Flurförderzeug ist somit die Anzeigevorrichtung in Blickrichtung des Fahrers auf den verdeckten Umgebungsbereich angeordnet und die Darstellung des verdeckten Umgebungsbereichs erfolgt für den Fahrer in einer auf den verdeckten Umgebungsbereich gerichteten Perspektive.According to the present invention, the direction of the virtual viewing channel is essentially congruent with the driver's viewing direction of the surrounding area. This has the advantage that the driver can look directly at a concealed field of vision, which is also referred to as the surrounding area, without the driver having to assume an unnatural position or posture within his driver's workplace - also and especially during vehicle operation - in order to to get a good view of the surrounding area near the industrial truck that is of interest to him. In the industrial truck according to the invention, the display device is therefore arranged in the driver's direction of view of the covered surrounding area and the covered surrounding area is displayed for the driver in a perspective directed towards the covered surrounding area.

Gemäß der vorliegenden Erfindung ist weiterhin eine Bildverarbeitungseinrichtung vorgesehen, welche ausgebildet ist, ein von der Aufnahmevorrichtung aufgenommenes Abbild eines Umgebungsbereiches für den im Fahrerschutzdach befindlichen Fahrer von einer der Aufnahmevorrichtung spezifischen Perspektive in eine für den im Fahrerschutzdach befindlichen Fahrer fahrerspezifischen Perspektive umzurechnen, welche in der Anzeigevorrichtung darstellbar ist. Dadurch wird der Vorteil erreicht, dass der Fahrer eine möglichst realitätsgetreue Darstellung des aufgenommenen Abbildes des über den virtuellen Sichtkanal einzusehenden Umgebungsbereiches erhält. Der Fahrer erhält also eine Darstellung des aufgenommenen Abbildes, welchem einem Bild entsprechen würde, wenn er direkt auf den nicht verdeckten Umgebungsbereich blicken würde.According to the present invention, an image processing device is also provided, which is designed to convert an image recorded by the recording device of an area surrounding the driver in the overhead guard from a perspective specific to the recording device into a driver-specific perspective for the driver in the overhead guard, which is displayed in the display device is representable. This achieves the advantage that the driver receives a representation of the recorded image of the surrounding area to be viewed via the virtual viewing channel that is as realistic as possible. The driver thus receives a representation of the recorded image, which would correspond to an image if he were to look directly at the surrounding area that is not covered.

Gemäß einer Ausführungsform der vorliegenden Erfindung ist die Anzeigevorrichtung im Wesentlichen senkrecht zur Richtung des virtuellen Sichtkanals ausrichtbar. Dadurch wird der Vorteil erreicht, dass der Fahrer im Fahrerarbeitsplatz direkt auf einen ihn interessierenden Umgebungsbereich oder Sichtbereich blicken kann, ohne dass er dazu eine neue oder unnatürliche und für ihn unbequeme Körperhaltung einnehmen muss, die ihn zusätzlich oder unnötig belastet und ihn damit auch von den Aufgaben zum sicheren Betrieb des Flurförderzeugs ablenkt.According to an embodiment of the present invention, the display device can be aligned substantially perpendicular to the direction of the virtual viewing channel. This has the advantage that the driver is directly in the driver's workplace can look at a surrounding area or field of view that interests him without having to assume a new or unnatural and uncomfortable posture that causes additional or unnecessary stress and thus also distracts him from the task of safe operation of the industrial truck.

Gemäß einer Ausführungsform der vorliegenden Erfindung ist die Aufnahmevorrichtung zur Erzeugung eines Abbildes des Umgebungsbereiches an dem Hubgerüst und / oder an dem Fahrerschutzdach und / oder an dem Fahrzeugkörper anbringbar ist. Dadurch wird der Vorteil erreicht, dass der für den Fahrer im Fahrerarbeitsplatz jeweils zu beobachtende Umgebungsbereich in der Nähe des Flurförderzeugs, welchen er direkt einsehen möchte, in Abhängigkeit von der Position der Aufnahmevorrichtung einstellbar ist.According to one embodiment of the present invention, the recording device for generating an image of the surrounding area can be attached to the mast and/or to the driver's overhead guard and/or to the vehicle body. This achieves the advantage that the surrounding area to be observed by the driver in the driver's workplace in the vicinity of the industrial truck, which he would like to see directly, can be adjusted as a function of the position of the recording device.

Gemäß einer Ausführungsform der vorliegenden Erfindung ist die Aufnahmevorrichtung zur Erzeugung eines virtuellen Sichtkanals zu dem Umgebungsbereich im Bereich eines Lastaufnahmemittels am Hubgerüst anbringbar. Dadurch wird der Vorteil erreicht, dass zum Beispiel ein Bereich um den Gabelträger oder die Spitzen der am Gabelträger angeordneten Gabelzinken aufgenommen werden kann und von dem Fahrer in seinem Fahrerarbeitsplatz direkt und in Echtzeit insbesondere während des Fahrzeugbetriebs ständig eingesehen werden kann. Auf diese Weise kann der Fahrer sein Fahrzeug und dessen Position genauer und schneller ausrichten.According to one embodiment of the present invention, the recording device for generating a virtual visual channel to the surrounding area can be attached to the mast in the area of a load handling device. This has the advantage that, for example, an area around the fork carriage or the tips of the fork tines arranged on the fork carriage can be recorded and can be viewed directly and in real time by the driver in his driver's workplace, especially during vehicle operation. In this way, the driver can align his vehicle and its position more precisely and quickly.

Gemäß einer Ausführungsform der vorliegenden Erfindung ist die Anzeigevorrichtung an einer Frontkonsole des Fahrerschutzdaches angeordnet. Dadurch wird der Vorteil erreicht, dass der Fahrer von seinem Fahrerarbeitsplatz aus direkt in den zu beobachtenden Umgebungsbereich im Bereich des Lastaufnahmemittels, also einen Frontbereich des Flurförderzeugs, blicken kann. Der Blick des Fahrers auf die Anzeigevorrichtung entspricht damit also seiner natürlichen Blickrichtung auf den betreffenden Umgebungsbereich, wenn dieser nicht verdeckt wäre. Der Fahrer muss als nicht auf eine Anzeigevorrichtung blicken, die sich an einer anderen Position befindet, als die Position des zu beobachtenden Umgebungsbereiches. Dadurch wird für den Fahrer auf seinem Fahrerarbeitsplatz der Eindruck erzeugt, als würde er vor einem sogenannten durchsichtigen Cockpit des Flurförderzeugs sitzen. Dies bedeutet, dass die Frontkonsole, die den direkten Blick des Fahrers auf den Bereich des Lastaufnahmemittels verdeckt, für den Fahrer durchsichtig bzw. transparent wird.According to one embodiment of the present invention, the display device is arranged on a front console of the overhead guard. This achieves the advantage that the driver can look from his driver's workplace directly into the surrounding area to be observed in the area of the load handling device, ie a front area of the industrial truck. The driver's view of the display device thus corresponds to his natural direction of view of the surrounding area in question if this were not covered. The driver does not have to look at a display device that is located at a different position than the position of the surrounding area to be observed. This gives the driver the impression that he is sitting in front of a so-called transparent cockpit of the industrial truck. This means, that the front console, which covers the driver's direct view of the area of the load handling device, becomes transparent for the driver.

Gemäß einer Ausführungsform der vorliegenden Erfindung ist die Aufnahmevorrichtung zur Erzeugung eines virtuellen Sichtkanals zu dem Umgebungsbereich, welcher von einem Kotflügel des Flurförderzeugs und / oder einem Reifen des Flurförderzeugs verdeckt ist, an dem Fahrerschutzdach oder an dem Fahrzeugkörper angebracht. Dadurch wird der Vorteil erreicht, dass der Fahrer ein Abbild des Umgebungsbereiches erhält, den er von seinem Fahrerarbeitsplatz aus sonst nicht direkt einsehen kann. Insbesondere die Bereiche um die Reifen des Flurförderzeugs herum, können kritische Bereiche darstellen, durch deren Beobachtung und Einsicht Kollisionen vermieden werden können.According to one embodiment of the present invention, the recording device for generating a virtual visual channel to the surrounding area, which is covered by a fender of the industrial truck and/or a tire of the industrial truck, is attached to the overhead guard or to the vehicle body. This achieves the advantage that the driver receives an image of the surrounding area, which he cannot otherwise see directly from his driver's workplace. In particular, the areas around the tires of the industrial truck can be critical areas, and collisions can be avoided by observing and understanding them.

Gemäß einer Ausführungsform der vorliegenden Erfindung ist die Anzeigevorrichtung an dem Fahrerschutzdach angeordnet. Dadurch wird der Vorteil erreicht, dass ein Umgebungsbereich, welchen der Fahrer von seinem Fahrerarbeitsplatz nicht direkt einsehen kann, dem Fahrer über den virtuellen Sichtkanal angezeigt wird. Die Anordnung der Anzeigevorrichtung an dem Fahrerschutzdach entspricht damit einer natürlichen Blickrichtung des Fahrers am Fahrerarbeitsplatz auf den betreffenden Umgebungsbereich, auf welchen der Fahrer auch ohne Anzeigevorrichtung direkt blicken würde, wenn dieser nicht verdeckt wäre.According to one embodiment of the present invention, the display device is arranged on the overhead guard. This achieves the advantage that a surrounding area which the driver cannot see directly from his driver's workplace is displayed to the driver via the virtual viewing channel. The arrangement of the display device on the overhead guard thus corresponds to a natural line of sight of the driver at the driver's workplace to the surrounding area in question, which the driver would also look at directly without the display device if it were not covered.

Gemäß einer Ausführungsform der vorliegenden Erfindung ist die Aufnahmevorrichtung zur Erzeugung eines virtuellen Sichtkanals zu einem Umgebungsbereich, welcher sich zumindest teilweise unter dem Flurförderzeug befindet, unterhalb des Flurförderzeugs anbringbar. Dadurch wird der Vorteil erreicht, dass der Fahrer auf seinem Fahrerarbeitsplatz ein Abbild auf einen Umgebungsbereich erhält, der sich zumindest teilweise unter dem Flurförderzeug befindet, ohne dass sich der Fahrer von seiner ursprünglichen Position auf dem Fahrerarbeitsplatz, insbesondere während des Fahrzeugbetriebes, entfernen muss oder eine ihm unnatürliche Körperhaltung einnehmen muss.According to one embodiment of the present invention, the recording device for generating a virtual visual channel to a surrounding area, which is at least partially below the industrial truck, can be attached below the industrial truck.

This achieves the advantage that the driver at his driver's workplace receives an image of the rear area of the vehicle, which is normally covered by the counterweight of the vehicle, particularly when the vehicle is moving backwards.

Gemäß einer Ausführungsform der vorliegenden Erfindung ist die Anzeigevorrichtung in einem Heckbereich des Flurförderzeugs oder an einem Heckbereich des Fahrerschutzdaches angeordnet. Dadurch wird der Vorteil erreicht, dass der Fahrer an seinem Fahrerarbeitsplatz durch eine entsprechende Änderung seiner Körperhaltung oder seiner Position, insbesondere bei einer rückwärtigen Fahrbewegung des Fahrzeugs, durch einen Blick auf die Anzeigevorrichtung direkt in den Heckbereich des Fahrzeugs blickt, welcher normalerweise durch das Gegengewicht des Fahrzeugs verdeckt wird. Der Blick des Fahrers auf die Anzeigevorrichtung entspricht damit seiner natürlichen Blickrichtung in den Heckbereich, wenn dieser nicht verdeckt wäre.According to one embodiment of the present invention, the display device is arranged in a rear area of the industrial truck or on a rear area of the driver's overhead guard. This achieves the advantage that the driver at his driver's workplace by changing his posture or his position, in particular when the vehicle is moving backwards, by looking at the display device looks directly into the rear area of the vehicle, which is normally covered by the counterweight of the vehicle is covered. The driver's view of the display device thus corresponds to his natural line of sight into the rear area if this were not covered.

Gemäß einer Ausführungsform der vorliegenden Erfindung weist der Heckbereich des Flurförderzeugs eine Anhängerkupplung auf. Dadurch wird der Vorteil erreicht, dass die sonst verdeckte Anhängerkupplung bei entsprechender Anordnung der Aufnahmevorrichtung von dem Fahrer an seinem Fahrerarbeitsplatz durch den virtuellen Sichtkanal auf diesen Bereich direkt eingesehen werden kann.According to one embodiment of the present invention, the rear area of the industrial truck has a trailer hitch. This achieves the advantage that the trailer hitch, which is otherwise hidden, can be viewed directly by the driver at his driver's workplace through the virtual viewing channel in this area, given a corresponding arrangement of the recording device.

Gemäß einer Ausführungsform der vorliegenden Erfindung ist das Abbild oder ein Teil des Abbildes eines von der Aufnahmevorrichtung aufgenommenen Umgebungsbereiches zumindest teilweise in Echtzeit und / oder als eine in einer Speichervorrichtung des Flurförderzeugs hinterlegte Aufnahme an die Anzeigevorrichtung übertragbar. Dadurch wird der Vorteil erreicht, dass der Fahrer insbesondere während des Fahrbetriebes zumindest teilweise durch den virtuellen Sichtkanal in verdeckte Umgebungsbereiche blicken kann und der Fahrer stets aktuelle Informationen darüber erhält, ob sich zum Beispiel in einem von ihm beobachteten Umgebungsbereich Objekte befinden, denen er mit seinem Fahrzeug ausweichen muss oder die ihn veranlassen, das Fahrzeugverhalten entsprechend anzupassen.According to one embodiment of the present invention, the image or part of the image of a surrounding area recorded by the recording device can be transmitted to the display device at least partially in real time and/or as a recording stored in a storage device of the industrial truck.

Die Anzeigevorrichtung 6 ist ferner ausgebildet, den von der Aufnahmevorrichtung 7 aufgenommenen Umgebungsbereich 8 derart anzuzeigen, dass ein virtueller Sichtkanal 9 durch das Flurförderzeug 1 hindurch erzeugbar ist, durch welchen es dem im Fahrerarbeitsplatz 4 befindlichen Fahrer 12 ermöglicht wird, in dem von dem Flurförderzeug 1 verdeckten Umgebungsbereich 8 zu blicken.the figure 1 shows a side view of an industrial truck 1 according to the invention with a mast 2, an overhead guard 3 with a driver's workplace 4 for a driver 12 and a vehicle body 5. The industrial truck comprises a display device 6, which includes at least one display 22, and a recording device 7, which is at least a camera 21 can be formed, and the display device 6 can be electronically connected to the recording device 7 . The display device 6 is also designed to display the surrounding area 8 recorded by the recording device 7 in such a way that a virtual viewing channel 9 can be generated through the industrial truck 1, through which the driver 12 located in the driver's workplace 4 is enabled to view the area from the industrial truck 1 covert surrounding area 8 to look.

Die in der Figur 1 dargestellte Ausführungsform des erfindungsgemäßen Flurförderzeugs 1 umfasst eine Anzeigevorrichtung 6 in einem Frontbereich 26, welcher sich auf der Seite des Hubgerüsts 2 befindet. Weiterhin kann in einem Heckbereich 18 des Flurförderzeugs 1 eine Anzeigevorrichtung 6 angeordnet sein. Das in der Figur 1 dargestellte Flurförderzeug 1 umfasst weiterhin eine Aufnahmevorrichtung 7a, welche im Frontbereich 26 angeordnet ist, um ein Abbild eines von dem Flurförderzeug 1 verdeckten Umgebungsbereiches 8 aufzunehmen, der von dem am Fahrerarbeitsplatz 4 befindlichen Fahrer 12 nicht unmittelbar oder direkt einsehbar ist. Zusätzlich kann eine weitere Aufnahmevorrichtung 7b, welche im Heckbereich 18 des Flurförderzeugs 1 angeordnet ist, um ein Abbild eines von dem Flurförderzeug 1 verdeckten Umgebungsbereiches 8 aufzunehmen, der von dem am Fahrerarbeitsplatz 4 befindlichen Fahrer 12 nicht unmittelbar oder direkt einsehbar ist.The one in the figure 1 Illustrated embodiment of the industrial truck 1 according to the invention comprises a display device 6 in a front area 26, which is located on the side of the mast 2. Furthermore, a display device 6 can be arranged in a rear area 18 of the industrial truck 1 . That in the figure 1 The industrial truck 1 shown also includes a recording device 7a, which is arranged in the front area 26 in order to record an image of a surrounding area 8 that is covered by the industrial truck 1 and that cannot be directly or directly viewed by the driver 12 located at the driver's workplace 4. In addition, a further recording device 7b, which is arranged in the rear area 18 of the industrial truck 1, in order to record an image of an area 8 covered by the industrial truck 1, which is not immediately or directly visible to the driver 12 located at the driver's workplace 4.

Die Richtung des in der Figur 1 dargestellten virtuellen Sichtkanals 9 ist im Wesentlichen deckungsgleich zu der Blickrichtung des Fahrers 12 auf den Umgebungsbereich 8. Aus der Figur 1 ist ebenfalls darstellbar, dass die Anzeigevorrichtung 6 im Wesentlichen senkrecht zur Richtung des virtuellen Sichtkanals 9 ausgerichtet ist. Dadurch wird der Vorteil erreicht, dass der Fahrer 12 im Fahrersitzplatz 4 auf das in der Anzeigevorrichtung 6 dargestellte und von der Aufnahmevorrichtung 7 aufgenommene Abbild eines Umgebungsbereiches 8 auf eine Weise blickt, als würde er durch die diesen Umgebungsbereich 8 sichtverhindernde Komponente des Flurförderzeugs 1 - zum Beispiel das Hubgerüst 2 oder den Fahrzeugkörper 5 - direkt hindurchblicken. Dadurch entsteht beim Fahrer 12 der Eindruck, dass die sichtverhindernde Komponente des Flurförderzeugs 1 über diesen virtuellen Sichtkanal 9, der dem Fahrer 12 die direkte Sicht auf den ansonsten verdeckten Umgebungsbereich 8 ermöglicht, ausgeblendet ist.The direction of the figure 1 The virtual viewing channel 9 shown is essentially congruent with the direction in which the driver 12 is looking at the surrounding area 8. From FIG figure 1 it can also be shown that the display device 6 is aligned essentially perpendicular to the direction of the virtual viewing channel 9 . This achieves the advantage that the driver 12 in the driver's seat 4 looks at the image of a surrounding area 8 shown on the display device 6 and recorded by the recording device 7 in a way as if he were being blocked by the component of the industrial truck 1 that prevents this surrounding area 8 from being seen - for example Example the mast 2 or the vehicle body 5 - look directly through. This creates the driver 12 of Impression that the view-obstructing component of the industrial truck 1 is hidden via this virtual viewing channel 9, which allows the driver 12 to have a direct view of the surrounding area 8 that is otherwise covered.

In der Figur 1 sind verschiedene Beispiele dargestellt, an welchen Positionen innerhalb des Flurförderzeugs 1 die Aufnahmevorrichtung 7 angebracht werden kann, um Abbilder von verschiedenen Umgebungsbereichen 8 in der Nähe des Flurförderzeugs 1 zu generieren. So ist zum Beispiel eine Aufnahmevorrichtung 7a an dem Hubgerüst 2 angebracht, wobei das Hubgerüst 2 als Bestandteil eines Lastaufnahmemittels 13 ausgebildet ist. Das Lastaufnahmemittel 13 kann dabei auch den Gabelträger oder die Gabelspitzen der Gabenzinken umfassen. An jeder dieser Elemente lässt sich ebenso eine Aufnahmevorrichtung 7 anbringen (nicht in der Figur 1 dargestellt). Eine weitere Aufnahmevorrichtung 7b ist an dem Fahrzeugkörper 5 angeordnet und eine weitere Aufnahmevorrichtung 7c ist an dem Fahrerschutzdach 3 bzw. dem Fahrzeugkörper 5 angeordnet.In the figure 1 Various examples are shown at which positions within the industrial truck 1 the recording device 7 can be attached in order to generate images of different environmental areas 8 in the vicinity of the industrial truck 1 . For example, a receiving device 7a is attached to the mast 2, the mast 2 being designed as part of a load handling device 13. The load handling device 13 can also include the fork carriage or the fork tips of the fork tines. A receiving device 7 can also be attached to each of these elements (not shown in the figure). figure 1 shown). A further receiving device 7b is arranged on the vehicle body 5 and a further receiving device 7c is arranged on the overhead guard 3 or the vehicle body 5 .

Als weiteres Beispiel, das jedoch nicht in der Figur 1 dargestellt ist, kann die Aufnahmevorrichtung 7 zur Erzeugung eines virtuellen Sichtkanals 9 zu einem Umgebungsbereich 8, welcher sich zumindest teilweise unter dem Flurförderzeug 1 befindet, auch unterhalb des Flurförderzeugs 1 angebracht sein.As another example, but not in the figure 1 is shown, the recording device 7 for generating a virtual viewing channel 9 to a surrounding area 8, which is at least partially below the industrial truck 1, can also be attached below the industrial truck 1.

Zusätzlich kann die Aufnahmevorrichtung 7, wie in der Figur 1 dargestellt, zur Erzeugung eines virtuellen Sichtkanals 9 zu einem Umgebungsbereich 8, welcher sich in einem Heckbereich 18 des Flurförderzeugs 1 befindet, im Heckbereich 18 des Flurförderzeugs 1 oder an dem Fahrerschutzdach 3 oder an dem Fahrzeugkörper 5 des Flurförderzeugs 1 angebracht sein. Der Heckbereich 18 des Flurförderzeugs 1 kann eine Anhängerkupplung 19 aufweisen, auf die der Fahrer 12 durch einen entsprechenden virtuellen Sichtkanal 9, der die direkte Sicht auf diesen Bereich ermöglicht, blicken kann.In addition, the recording device 7, as in the figure 1 shown, to generate a virtual viewing channel 9 to a surrounding area 8, which is located in a rear area 18 of the industrial truck 1, in the rear area 18 of the industrial truck 1 or on the driver's overhead guard 3 or on the vehicle body 5 of the industrial truck 1. The rear area 18 of the industrial truck 1 can have a trailer hitch 19, which the driver 12 can look at through a corresponding virtual viewing channel 9, which enables a direct view of this area.

Das Flurförderzeug 1 kann deshalb auch eine Vielzahl von Aufnahmevorrichtungen 7 aufweisen, die an verschiedenen Positionen innerhalb des Flurförderzeugs 1 angeordnet sind.The industrial truck 1 can therefore also have a large number of receiving devices 7 which are arranged at different positions inside the industrial truck 1 .

Zur Anzeige der jeweils von den einzelnen Aufnahmevorrichtungen 7 erzeugten Abbilder der verschiedenen Umgebungsbereiche 8 sind an den verschiedenen Positionen innerhalb des Flurförderzeugs 1 Anzeigevorrichtungen 6 installiert. Die Figur 1 zeigt dazu entsprechende Beispiele. So ist zum Beispiel ein Display 22a an einer Frontkonsole 17 am Fahrerschutzdach 3 angeordnet, um dem Fahrer 12 am Fahrerarbeitsplatz 4 die direkte Sicht auf einen Umgebungsbereich 8 zu ermöglichen, welcher von der Frontkonsole 17 verdeckt ist. Ein weiteres Display 22b kann im Fahrerarbeitsplatz hinter dem Fahrersitz 28 angeordnet sein, um dem Fahrer 12 im Fahrerarbeitsplatz 4 eine direkte Sicht auf einen Umgebungsbereich 8 zu ermöglichen, welcher vom Heckbereich 18 des Flurförderzeugs verdeckt ist. Ein weiterer Display 22c kann im Beinbereich des Fahrerarbeitsplatzes angeordnet sein, um dem Fahrer 12 im Fahrerarbeitsplatz 4 eine direkte Sicht auf einen Umgebungsbereich 8 zu ermöglichen, welcher von einem Kotflügel 15 des Flurförderzeugs 1 und / oder einem Reifen 16 des Flurförderzeugs 1 verdeckt ist. Um diese von einem Kotflügel 15 oder einem Reifen 16 verdeckten Umgebungsbereiche 8 für den Fahrer 12 sichtbar zu machen, kann die Anzeigevorrichtung 6 jedoch auch direkt an dem Fahrerschutzdach 3 oder an dem Fahrzeugkörper 5 angebracht sein.Display devices 6 are installed at the different positions within the industrial truck 1 to display the images of the various surrounding areas 8 produced by the individual recording devices 7 . the figure 1 shows relevant examples. For example, a display 22a is arranged on a front console 17 on the overhead guard 3 in order to enable the driver 12 at the driver's workplace 4 to have a direct view of a surrounding area 8 which is covered by the front console 17 . Another display 22b can be arranged in the driver's workplace behind the driver's seat 28 in order to enable the driver 12 in the driver's workplace 4 to have a direct view of a surrounding area 8 which is covered by the rear area 18 of the industrial truck. Another display 22c can be arranged in the leg area of the driver's workplace in order to give the driver 12 in the driver's workplace 4 a direct view of a surrounding area 8 which is covered by a fender 15 of the industrial truck 1 and/or a tire 16 of the industrial truck 1. However, in order to make these surrounding areas 8 covered by a fender 15 or a tire 16 visible to the driver 12 , the display device 6 can also be attached directly to the driver's overhead guard 3 or to the vehicle body 5 .

Wenn dem Fahrer 12 eine direkte Sicht auf das Lastaufnahmemittel 13 ermöglicht werden soll, dann kann dazu, wie in der Figur 1 dargestellt, eine entsprechende Kamera 7a in einem Bereich des Lastaufnahmemittels 13 oder am Hubgerüst 2 angeordnet sein, um ein entsprechendes Abbild des Bereiches des Lastaufnahmemittels 13 aufnehmen zu können. Das dazugehörige Display 22a der Anzeigevorrichtung 6, auf welches dann der Fahrer 13 direkt blickt, welches das aufgenommene Abbild des Bereiches des Lastaufnahmemittels 13 anzeigt, ist dann vorzugsweise an der Frontkonsole 17 angebracht.If the driver 12 should be allowed a direct view of the load handling device 13, then this can, as in the figure 1 shown, a corresponding camera 7a can be arranged in an area of the load handling device 13 or on the mast 2 in order to be able to record a corresponding image of the area of the load handling device 13 . The associated display 22a of the display device 6, on which the driver 13 then looks directly, which displays the recorded image of the area of the load handling device 13, is then preferably attached to the front console 17.

Wenn der Fahrer 12 einen direkten Blick auf die Anhängerkupplung 19 des Flurförderzeugs 1 werfen möchte, dann ist es sinnvoll, eine entsprechende Anzeigevorrichtung 6b, wie in der Figur 1 dargestellt, in dem Heckbereich 18 des Flurförderzeugs oder an einem Heckbereich des Fahrerschutzdaches 3 anzuordnen, damit ein entsprechender virtueller Sichtkanal 9 dem Fahrer 12 an seinem Fahrerarbeitsplatz 4 eine direkte Sicht auf die Anhängerkupplung 19 ermöglicht wird. Das dazugehörige Display 22b der Anzeigevorrichtung 6 ist dann vorzugsweise, wie in der Figur 1 dargestellt, im Fahrerschutzdach 3 schräg hinter einem Fahrersitz 28 angeordnet.If the driver 12 wants to take a direct look at the trailer hitch 19 of the industrial truck 1, then it makes sense to have a corresponding display device 6b, as in FIG figure 1 shown to be arranged in the rear area 18 of the industrial truck or on a rear area of the driver's overhead guard 3 so that a corresponding virtual viewing channel 9 allows the driver 12 at his driver's workplace 4 to have a direct view of the trailer hitch 19 . The associated display 22b of the display device 6 is then preferably, as in the figure 1 shown, arranged diagonally behind a driver's seat 28 in the overhead guard 3 .

Wenn dem Fahrer 12 eine direkte Sicht auf das Rad 16, einem durch das Rad 16 oder dem Kotflügel 15 verdeckten Bereich ermöglicht werden soll, dann kann dazu, wie in der Figur 1 dargestellt, eine entsprechende Kamera 7c in einem Bereich des Fahrerschutzdaches 3 angeordnet sein, um ein entsprechendes Abbild dieses Bereiches aufnehmen zu können. Das dazugehörige Display 22c der Anzeigevorrichtung 6, auf welches dann der Fahrer 13 direkt blickt, welches das aufgenommene Abbild des Bereiches um den Kotflügel 15 oder des Rads 16 anzeigt, ist dann vorzugsweise in einem entsprechenden Bereich des Fahrerschutzdaches 3 angebracht, wie in der Figur 1 dargestellt.If the driver 12 is to be able to have a direct view of the wheel 16, an area covered by the wheel 16 or the fender 15, then this can be done, as in FIG figure 1 shown, a corresponding camera 7c can be arranged in an area of the overhead guard 3 in order to be able to record a corresponding image of this area. The associated display 22c of the display device 6, on which the driver 13 then looks directly, which displays the recorded image of the area around the fender 15 or the wheel 16, is then preferably mounted in a corresponding area of the overhead guard 3, as in FIG figure 1 shown.

Die Anzeigevorrichtung 6 kann auch ausgebildet sein, ein Abbild oder mehrere Abbilder mehrerer Umgebungsbereiche 8 gleichzeitig anzuzeigen, welche sich auch in ihrer Perspektive zu einem Gesamtbild ergänzen lassen, so dass dem Fahrer 12 eine sogenannte 360°-Rundumperspektive eines ansonsten verdeckten Umgebungsbereiches 8 angeboten wird.The display device 6 can also be designed to display an image or multiple images of several surrounding areas 8 at the same time, the perspective of which can also be supplemented to form an overall picture, so that the driver 12 is offered a so-called 360° all-round perspective of an otherwise covered surrounding area 8.

Das Abbild oder ein Teil des Abbildes eines von der Aufnahmevorrichtung 7 aufgenommenen Umgebungsbereiches 8 ist dabei zumindest teilweise in Echtzeit und / oder als eine in einer Speichervorrichtung 20 des Flurförderzeugs 1 hinterlegte Aufnahme an die Anzeigevorrichtung 6 übertragbar. Dadurch können dem Fahrer 12 stets eine Anzahl von aktuellen Abbildern von Umgebungsbereichen 8 angeboten werden, auf welche er durch ein angepasstes Fahrverhalten entsprechend reagieren kann.The image or part of the image of a surrounding area 8 recorded by the recording device 7 can be transmitted to the display device 6 at least partially in real time and/or as a recording stored in a storage device 20 of the industrial truck 1 . As a result, the driver 12 can always be offered a number of current images of environmental regions 8 to which he can react accordingly by adapting his driving behavior.

In der Figur 1 umfasst das dargestellte Flurförderzeug 1 eine Anzeigevorrichtung 6, die ein erstes Display 22a umfasst, das in der Figur 1 im Frontbereich 26 des Flurförderzeugs 1 angeordnet ist. Ein weiteres Display 22b der Anzeigevorrichtung 6 ist in der Figur 1 im Heckbereich 18 des Flurförderzeugs 1 angeordnet. Ein weiteres Display 22c der Anzeigevorrichtung 6 kann innerhalb des Fahrerarbeitsplatzes 4 angeordnet. Das erste Display 22a und / oder das weitere Display 22b bzw. 22c können ausgebildet sein, zusätzliche Fahrzeuginformationen, zum Beispiel Warnhinweise, geänderte Transportrouten, Alarme oder Lastdiagramme, anzuzeigen.In the figure 1 includes the illustrated truck 1, a display device 6, which includes a first display 22a, which is in the figure 1 is arranged in the front area 26 of the industrial truck 1 . Another display 22b of the display device 6 is in FIG figure 1 arranged in the rear area 18 of the industrial truck 1 . Another display 22c of the display device 6 can be arranged inside the driver's workplace 4 . The first display 22a and/or the further display 22b or 22c can be designed to display additional vehicle information, for example warnings, changed transport routes, alarms or load diagrams.

Ferner kann in dem in der Figur 1 dargestellten Flurförderzeug 1 eine Bildverarbeitungseinrichtung 23 vorgesehen sein, welche ausgebildet ist, ein von der Aufnahmevorrichtung 7 aufgenommenes Abbild eines Umgebungsbereiches 8 für den im Fahrerschutzdach 3 befindlichen Fahrer 12 von einer der Aufnahmevorrichtung 7 spezifischen Perspektive in eine für den im Fahrerschutzdach 3 befindlichen Fahrer 12 fahrerspezifischen Perspektive umzurechnen, welche in der Anzeigevorrichtung 6 darstellbar ist. Auf diese Weise wird es dem Fahrer 12 ein Eindruck vermittelt, als würde er unmittelbar und geradewegs hindurch durch die einen Umgebungsbereich 8 verdeckende Komponente des Flurförderzeugs 1 blicken. Durch diese fahrerspezifische Perspektive wird dem Fahrer 12 also eine quasi natürliche aber emulierte Sicht auf einen verdeckten Umgebungsbereich 8 angeboten.Furthermore, in the in the figure 1 industrial truck 1 shown, an image processing device 23 may be provided, which is designed to convert an image of an area 8 recorded by recording device 7 for the driver 12 located in overhead guard 3 from a perspective specific to recording device 7 into a driver-specific perspective for driver 12 located in overhead guard 3 to convert, which can be displayed in the display device 6. In this way, the driver 12 is given the impression that he is looking directly and straight through the component of the industrial truck 1 that covers a surrounding area 8 . This driver-specific perspective therefore offers the driver 12 a quasi-natural but emulated view of a concealed surrounding area 8 .

Diese fahrerspezifische Perspektive in der Anzeigevorrichtung 6 kann von dem im Fahrzeugschutzdach 3 befindlichen Fahrer 12 mittels eines Bedienelements 24 in dem Flurförderzeug 1, welches mit der Bildverarbeitungseinrichtung 23 elektronisch verbindbar ist, manuell einstellt werden. Auf diese Weise kann das Fahrzeug 1 von verschiedenen Fahrern benutzt werden, die die für sie und ihre Körpergröße geeignete fahrerspezifische Perspektive auf ihre Erfordernisse einstellen können.This driver-specific perspective in the display device 6 can be set manually by the driver 12 in the vehicle protective roof 3 using an operating element 24 in the industrial truck 1, which can be electronically connected to the image processing device 23. In this way, the vehicle 1 can be used by different drivers, who can set the driver-specific perspective that is suitable for them and their body size to their requirements.

Über eine Sensorvorrichtung 25, welche in dem Flurförderzeug 1 vorgesehen sein kann, kann automatisch eine Position eines Fahrerkopfes oder der Augen eines im Fahrerschutzdach 3 befindlichen Fahrers 12 ermittelt werden, damit die fahrerspezifische Perspektive in Abhängigkeit dieser aufgenommenen Position des Fahrerkopfes oder der Augen auf der Anzeigevorrichtung 6 darstellbar und damit auch individuell einstellbar ist. Derartige Einstellungen können für verschiedene Fahrer in Form von Fahrerprofilen zum Beispiel in der Speichervorrichtung 20 hinterlegt werden. Die jeweiligen Fahrerprofile können dann bei einem Fahrerwechsel von dem jeweiligen Fahrer geladen werden, so dass dieser ohne Verzögerungen das Fahrzeug in Betrieb nehmen und seinen Transportauftrag zügig ausführen kann.A sensor device 25, which can be provided in the industrial truck 1, can automatically determine the position of a driver's head or the eyes of a driver 12 located in the overhead guard 3, so that the driver-specific perspective is displayed on the display device as a function of this recorded position of the driver's head or eyes 6 can be displayed and is therefore also individually adjustable. Such settings can be stored for different drivers in the form of driver profiles, for example in the storage device 20 . The respective driver profiles can then be loaded by the respective driver when there is a driver change, so that he can put the vehicle into operation without delay and carry out his transport order quickly.

Im Folgenden werden mögliche Lösungen für sogenannte in der Figur 1 angezeigte Kollisionsstellen A, B und C angegeben. Im Fall A der durch das Gegengewicht 27 verdeckten Anhängerkupplung 19 kann zum Beispiel eine Kamera 7b auf dem Gegengewicht 27 montiert werden. Das dazugehörige Display 22b kann dann zum Beispiel im Fahrerschutzdach 3 schräg hinter dem Fahrersitz 28 montiert sein. Bei Rückwärtsfahrt oder beim Manövrieren in engen Umgebungen kann der Fahrer 12 nun im Schulterblick sowohl den rückwärtigen Bereich des Fahrzeugs 1, also auch das Ende des Fahrzeugs 1 sehen, das im Display 22b dargestellt wird. Dabei wird nicht einfach das aufgenommene Kamerabild oder Abbild auf dem Display 22b dargestellt, sondern das Abbild wird durch die Bildverarbeitungseinrichtung 23 derart aufbereitet, damit es für den Fahrer 12 perspektivisch richtig - als in einer fahrerspezifischen Perspektive - dargestellt wird. Für den Fahrer 12 wird damit der Eindruck generiert, dass er durch den virtuellen Sichtkanal 9 oder ein entsprechendes Fenster in dem Fahrerschutzdach 3 und dem Gegengewicht 27 direkt auf die Anhängerkupplung 19 sehen würde.The following are possible solutions for so-called in the figure 1 indicated collision points A, B and C. In case A of the trailer hitch 19 covered by the counterweight 27, for example, a camera 7b can be mounted on the counterweight 27. The associated display 22b can then go to Example, be mounted diagonally behind the driver's seat 28 in the overhead guard 3 . When reversing or when maneuvering in tight surroundings, the driver 12 can now see both the rear area of the vehicle 1 and also the end of the vehicle 1, which is shown on the display 22b, by looking over his shoulder. The recorded camera image or image is not simply displayed on the display 22b, but the image is processed by the image processing device 23 in such a way that it is displayed in the correct perspective for the driver 12—as in a driver-specific perspective. The impression is thus generated for the driver 12 that he would be looking directly at the trailer hitch 19 through the virtual viewing channel 9 or a corresponding window in the overhead guard 3 and the counterweight 27 .

Der virtuelle Sichtkanal 9 und das entsprechende Fenster zum Gabelträger des Flurförderzeugs 1, der auch als Lastaufnahmemittel 13 bezeichnet wird und normalerweise von der Frontkonsole 17 verdeckt wird, könnte zum Beispiel, wie durch die Kollisionsstelle B in der Figur 1 dargestellt, durch eine Kamera 7a am Hubgerüst 2, wie in der Figur 1 dargestellt, und einem Display 22a an der Frontkonsole 17 realisiert werden.The virtual viewing channel 9 and the corresponding window to the fork carriage of the truck 1, which is also referred to as the load handling device 13 and is normally covered by the front panel 17, could, for example, as by the collision point B in the figure 1 shown by a camera 7a on the mast 2, as in FIG figure 1 shown, and a display 22a on the front panel 17 are realized.

Die Kollisionsstelle C auf dem Kotflügel 15 und die Vorderreifen 16, die normalerweise durch die A-Säule des Fahrerschutzdaches 3 und gegebenenfalls vorhandenen Türen (nicht dargestellt) verdeckt sind, könnten zum Beispiel durch entsprechende Kameras 7c auf den Kotflügeln 15 und Displays 22c an der Frontverkleidung des Flurförderzeugs 1 für den Fahrer 12 über einen virtuellen Sichtkanal 9 sichtbar oder direkt einsehbar gemacht werden.The collision point C on the fender 15 and the front tires 16, which are normally covered by the A-pillar of the driver's overhead guard 3 and any doors (not shown), could be, for example, by corresponding cameras 7c on the fenders 15 and displays 22c on the front panel of the industrial truck 1 can be made visible or directly visible to the driver 12 via a virtual viewing channel 9 .

Ferner kann über eine Displayteilung oder eine Displayumschaltung mehrere kritische Außenbereiche, also Umgebungsbereiche 8 auf einem Display 21 dargestellt werden. Zum Beispiel kann der rechte und der linke Kotflügel auf einem Display dargestellt werden. Bei einer Rückwärtsfahrt können gleichzeitig die Anhängerkupplung 19 und er schwer einsehbares Bereich im Rückraum eingeblendet werden, der entsteht, weil der Fahrer 12 seinen Kopf soweit drehen muss, um den Rückraum komplett einsehen zu können.Furthermore, a number of critical external areas, ie environmental areas 8, can be shown on a display 21 by dividing the display or by switching the display. For example, the right and left fenders can be shown on one display. When reversing, the trailer hitch 19 and the area in the rear that is difficult to see, which arises because the driver 12 has to turn his head far enough to be able to see the rear area completely, can be displayed at the same time.

Die Vorteile des erfindungsgemäßen Flurförderzeugs 1 mit einem oder mehreren virtuellen Sichtkanälen 9 zur direkten Einsicht von verdeckten Umgebungsbereichen 8 sind eine erhöhte Sicherheit, eine Verringerung der Häufigkeit und Schwere von Unfällen, eine Vermeidung von Ladegutbeschädigung, verbesserte Arbeitsbedingungen für den Fahrer 12, eine geringere Belastung des Fahrers 12 und eine höhere Umschlagsleistung von transportierten Waren mit dem Flurförderzeug 1.The advantages of the industrial truck 1 according to the invention with one or more virtual viewing channels 9 for direct viewing of covered surrounding areas 8 are increased safety, a reduction in the frequency and severity of accidents, avoidance of cargo damage, improved working conditions for the driver 12, less stress on the Driver 12 and a higher throughput of transported goods with industrial truck 1.

Ein weiterer Vorteil besteht darin, dass der Fahrer 12 durch den virtuellen Sichtkanal 9 und das entsprechende Fenster die kritischen Bereiche beurteilen kann, und gleichzeitig, weil ja das Display 22 in Richtung des kritischen Bereiches angebracht ist, den Rest der Umgebung wahrnehmen kann. Besonders deutlich wird das bei der Sicht auf die Anhängerkupplung 19 und auf das Fahrzeugende, weil der Fahrer im Schulterblick sowohl den kritischen Nahbereich im Display 22b als auch den übrigen Rückraum durch die Heckscheibe beurteilen kann. Der Fahrer 12 ist also nicht gezwungen, nach vorne zu blicken, obwohl er rückwärtsfahren möchte.A further advantage is that the driver 12 can assess the critical areas through the virtual viewing channel 9 and the corresponding window, and at the same time, because the display 22 is mounted in the direction of the critical area, can perceive the rest of the environment. This becomes particularly clear when looking at the trailer hitch 19 and the end of the vehicle, because the driver can assess both the critical close-up area on the display 22b and the rest of the rear area through the rear window by looking over his shoulder. The driver 12 is therefore not forced to look ahead, although he would like to reverse.

Die vorliegende Erfindung ist dabei nicht auf Gegengewichtsgabelstapler beschränkt, sondern kann bei allen Flurförderzeugen angewendet werden, bei denen die Sicht des Fahrers auf Komponenten des Flurförderzeugs 1 verdeckt ist.The present invention is not limited to counterbalanced forklift trucks, but can be applied to all industrial trucks in which the driver's view of components of the industrial truck 1 is blocked.

Ganz allgemein bedeutet das sogenannte durchsichtige Cockpit des erfindungsgemäßen Flurförderzeugs 1 im Kontext der vorliegenden Erfindung, dass Kameras eine Sicht auf die Bereiche des Außenbereichs des Flurförderzeugs 1 aufnehmen, die durch Komponenten des Flurförderzeugs wie zum Beispiel dem Fahrerschutzdach 3, Gabelträger, Gegengewicht 27, Stirnblech, Verkleidungen, Türen (nicht in der Figur 1 dargestellt) verdeckt sind. Entsprechend angeordnete Displays im Inneren des Flurförderzeugs 1 zeigen perspektivisch korrigierte Kamerasichten und vermitteln dem Fahrer 12 des Flurförderzeugs 1 auf diese Weise den Eindruck, durch sogenannte Fenster im Cockpit des Flurförderzeugs 1 auf wichtige Teil der Fahrzeugkontur sehen zu können.In very general terms, the so-called transparent cockpit of the industrial truck 1 according to the invention means in the context of the present invention that cameras record a view of the areas of the exterior of the industrial truck 1 that are covered by components of the industrial truck such as the driver's overhead guard 3, fork carriage, counterweight 27, front panel, Panels, doors (not in the figure 1 shown) are covered. Correspondingly arranged displays inside the industrial truck 1 show perspectively corrected camera views and in this way give the driver 12 of the industrial truck 1 the impression of being able to see important parts of the vehicle contour through so-called windows in the cockpit of the industrial truck 1 .
