There is a variety of possible applications: on-demand offerings in public transportation, delivery services, and mobile medical services or temporary accommodation. The concept, which features a rigorous separation of the vehicle from its function, was developed at the Institute of Vehicle Concepts of the German Aerospace Center (DLR) and has been pursued continuously across multiple projects at DLR for several years.
“Innovation is the key driver for tomorrow’s value creation in the automobile sector. This makes the U-Shift II project so important for SMEs. With its focus on technology transfer and the targeted involvement of medium-sized partners, this research and development project systematically strengthens the long-term competitiveness of Baden-Württemberg’s automobile industry when it comes to autonomous and networked driving,” said Dr. Nicole Hoffmeister-Kraut, Minister of Economic Affairs, Skilled Trades
and Tourism.
“We want to make vehicles that suit more than one single purpose,” said Professor Kora Kristof, Vice President for Digitalization and Sustainability at KIT. “A vehicle that adapts flexibly to different tasks saves resources. It’s a building block of sustainable mobility, and creates innovative options for Baden-Württemberg as a mobility hub.”
“The insights we gained in the U-Shift II project will help us to advance automated vehicle concepts and the technologies associated with them. With this research, we’re supporting Baden-Württemberg as an automotive hub, establishing important baselines for taking these innovative mobility ideas to practical application, and preparing their transfer to the road,” said Professor Meike Jipp, Director of the Energy and Transport division at DLR.
A Flat Drive Board at the Heart of the Concept
A key element of the concept is the flat drive board that includes the essential technical components such as the electric drive consisting of four hub motors, batteries, steering system, and central functions for control, monitoring, and energy supply. All of these were developed at the Research Institute for Automotive Engineering and Power Systems Stuttgart (FKFS). The drive board moves autonomously under the capsule intended for each task, lifts it up, and locks it in place. Human intervention is not necessary.
“The principle is similar to that of a swap container: Instead of designing dedicated vehicles for each task, the vehicle remains the same, only the superstructure changes,” said Dr. Michael Frey from KIT’s Institute of Vehicle Systems Technology (FAST). FAST was responsible for the design of the chassis with its integrated lifting system. It enables the vehicle to pick up and drop off the capsules without requiring additional infrastructure. “The implementation basically requires nothing more than a free space for the capsule and the vehicle,” explained Frey.
Technology that Adapts to Function
To pick up the capsule, the vehicle establishes a digital connection with it. “Thanks to the flexible technical architecture, the vehicle can adopt different functions depending on its task,” said Professor Eric Sax, who heads KIT’s Institute for Information Processing Technology (ITIV) where the electronic and software-based “control center” of the vehicle was developed. This unit interconnects and coordinates the various vehicle functions and capsule technologies. The functions and sensors automatically adapt to the selected capsule, for example, for transporting passengers or delivering goods. New software can be installed using a wireless connection, in much the same way as a smartphone update.
Safe on the Road, Accurate Docking
The vehicle uses sensors such as cameras, radar, and lidar to recognize its surroundings. The sensor concept as well as the systems for data processing and motion planning – which need to be performed with extreme accuracy during the docking process – have been developed at Ulm University. By interacting with the motion systems elaborated at the FKFS, the vehicle can carry out maneuvering and docking movements with centimeter precision. A locking system developed at the DLR keeps the capsule safely in place during travel.
Strong Research Team from Baden-Württemberg
The U-Shift II project is a collaboration of KIT, DLR, Ulm University, and FKFS; it is led and coordinated by DLR. The Baden-Württemberg Ministry of Economic Affairs, Skilled Trades and Tourism funded the project with EUR 10 million of which KIT received EUR 1.7 million.
