Space in warehouses is often a scarce commodity. Forklift drivers often have to manoeuvre their vehicles between shelves and parked parcels in confined spaces. Accidents that lead to scratches on the goods or the vehicles occur again and again. But far worse than the damage to property are the personal injuries which, according to a study by the trade association Berufsgenossenschaft Holz und Metall (BGHW), occur primarily when reversing in a nearby environment between one and three meters. In Germany alone, around 12,000 accidents involving forklift trucks are officially reported every year. A multi-camera system is therefore intended to relieve the forklift driver.
The system enables a 360° all-round view around the off-road vehicle via the function of the visual assistant – even with bulky goods. This makes it easy to pick up and move loads even in confined spaces. The system helps to manoeuvre the forklift truck precisely and to better estimate the distances while driving. The camera system consists of a control unit and four compact close-range cameras. This allows an area of up to eight by eight metres to be viewed. The cameras come from the Bosch passenger car sector and are adapted to the special requirements of the logistics market.
The cameras are oriented to the front, rear, and each side of the vehicle. With an opening angle of almost 190 degrees each, they cover the entire vehicle environment. The driver sees a realistic 3D model of his own vehicle on a display. As the vehicle moves, the environment is adapted in real time. The content of the screen pages between individual views and 360° panoramic view as well as the division into full screen and split screen pages can be preconfigured by the vehicle manufacturer according to the vehicle application. The driver then has the option of selecting the view suitable for the respective task from the preselection.
With the multi-camera system, the lane can be faded in from the front, rear or top view. For this purpose, the control unit records the steering angle, calculates the resulting lane and displays it on the display. If the steering angle changes, the resulting lane is recalculated and displayed accordingly. The lane display serves primarily as a manoeuvring and threading aid.
