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,
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the display device can be aligned substantially perpendicular to the direction of the virtual viewing channel.
  • 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.
  • 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.
  • 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.
  • the front console which covers the driver's direct view of the area of the load handling device, becomes transparent for the driver.
  • 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.
  • the areas around the tires of the industrial truck can be critical areas, and collisions can be avoided by observing and understanding them.
  • 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.
  • the recording device for generating a virtual visual channel to a surrounding area can be attached below the industrial truck.
  • This achieves the advantage that the driver receives an image of a surrounding area at his driver's workplace, which is at least partially under the industrial truck, without the driver having to move from his original position on the driver's workplace, in particular during vehicle operation, or a has to adopt an unnatural posture for him.
  • the recording device for generating a virtual visual channel to a surrounding area which is located in a rear area of the industrial truck, Can be attached to the rear of the industrial truck or to the driver's overhead guard or to the vehicle body of 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.
  • 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.
  • 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.
  • 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.
  • the display device is designed to display an image of a plurality of environmental regions at the same time.
  • the recording device comprises at least one camera which is designed to record at least one surrounding area. This achieves the advantage that an image of the surrounding area to be observed can be recorded electronically in order to generate a virtual viewing channel of this surrounding area for further processing of the image recorded by the camera.
