Elegant and maneuverable – the AutoTram® Extra Grand at the IAA Commercial Vehicles

18.09.2012
The AutoTram® Extra Grand currently does its laps on the DEKRA test track at the EuroSpeedway Lausitz, working through the testing procedure to obtain a single vehicle approval.
In past weeks, an increasing number of journalists and press representatives have been expressing their interest in this impressive vehicle. They are fascinated by its length, which raises several questions: How can a vehicle of this enormous size cope with the tight bends of city traffic? Is it a hazard to other traffic participants? How can the AutoTram® be maneuvered forward and reverse?

Scientists at the Fraunhofer Institute for Transportation and Infrastructure Systems IVI took up the challenge to make extra-long vehicles maneuverable in city traffic. This was achieved by equipping the vehicle with four steered axles in addition to the fixed main drive axle. A multi-axle steering system, developed and tested at the Fraunhofer IVI, has been implemented in the AutoTram® Extra Grand for the first time.

With this steering system, the vehicle has the maneuverability of a 12-meter city bus and can be operated by any licensed bus driver in the traffic network, forward and reverse. The AutoTram® Extra Grand was developed and constructed by seven partners within the »Innovative Regionale Wachstumskerne« research program, initiated by the German Federal Ministry of Research and Education (BMBF). The vehicle’s maneuverability is an important requirement for obtaining an approval. The German regulations for the operation of vehicles in passenger transport (BOKraft) require a turning radius of 12.5 meters, which is kept by the vehicle. As the AutoTram® Extra Grand has a tram-like swept path, the hazard to cyclists and pedestrians is smaller than with an 18-meter articulated bus.

Richard Kiemer, who has been employed at the AutoTram® Extra Grand’s manufacturer Göppel Bus for many years, steered the giant vehicle through Dresden’s narrow roads when it was first presented to the public this August. The well-experienced expert concludes: »I have been driving 24-meter buses with passenger trailers for several years. Now it is 6 meters more, which is again a challenge for me. But with this vehicle, I will be able to manage bends just the same«.

Liu Xiaoming, director of Beijing’s public transport, also had the pleasure of sitting behind the wheel and taking a test drive in the AutoTram® Extra Grand. His comment on the ride: »This bus has the look of a ship and drives like a car – quite comfortable«. The vehicle’s length obviously does not scare him. He ought to know – Liu Xiaoming manages a fleet of 220,000 vehicles.

From 20th to 27th September 2012, visitors can take a look at the AutoTram® Extra Grand, which will be exhibited on the innovation stage at the IAA Commercial Vehicles (International Motor Show) in Hannover.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
