Traveling in a Volkswagen that is still to be developed

Volkswagen Group’s IT Virtual Engineering Lab has developed a virtual concept car using digital future technology


A Volkswagen (VW) plant, the Technical Development department, Hall 70: a Golf rolls up. The hall has no windows but the vehicle glides through a sunny urban scene. Here, nothing is real, not even the Golf, and this model will only appear on the roads in a few years' time.

Nevertheless, Frank Ostermann and Mathias Möhring are already sitting in the car. Ostermann enters a new route while Möhring adjusts the air conditioning. It's all no problem. The virtual Golf and its surroundings are the result of groundbreaking teamwork between the Volkswagen Group IT Virtual Engineering Lab and the Technical Development department, which had a shared goal – they wanted to revolutionize the development of new Volkswagen models. They have succeeded: the next Golf will already be developed virtually.

Ostermann and Möhring are wearing virtual reality (VR) goggles connected to several computers. Möhring suggests that they should check the airflow of the air conditioning system again. What is the air delivery like at full load? At the touch of a button, transparent flow lines surround both of them.

Frank Ostermann heads the Virtual Engineering Lab in Wolfsburg, Germany, one of six competence centers now operated by Volkswagen Group IT. In the labs, IT experts, scientists and software specialists from VW work together with research institutes and technology partners on the digital future of the company.

"In the Virtual Engineering Lab, we transform virtual reality into a practical tool for our Technical Development colleagues," says Ostermann. One result is the virtual concept car. The program transfers all the design and simulation data of a VW prototype to a graphic engine of the type used in video games.

"With the virtual concept car, we are going beyond a purely three-dimensional approach," Ostermann explains. "We combine a full feeling of space with functionality. A driver not only looks at their car but also controls it. So that's what we do in the virtual car, simply with hand movements, without a physical control. As in a real car." Ostermann shows how this can be done and selects another radio station on the virtual infotainment system.

VW is using virtual concept cars for the development of production models. The next Golf generation is being developed with this new tool. Möhring, who holds a doctorate in engineering, is responsible for the digitization of the product creation process with Volkswagen Technical Development. He says, "We use all the possibilities offered by digitization. The virtual concept car is a good example. And we still have a few ideas up our sleeve."

But why are virtual reality applications such as the virtual concept car needed? The virtual concept car saves development costs. The number of physical prototypes that need to be produced individually in a costly process can be reduced. This represents a considerable improvement in efficiency for the Volkswagen brand with its wide model range.

The virtual concept car also saves time. As all the components are designed digitally, their data can easily be transferred to the program. The result is a virtual, properly functioning car on which all the development team members can work together at the same time. "We already hold specific discussions at a very early stage; this would not be possible with physical prototypes and represents a gigantic leap forward," Möhring reports.

Ostermann and his team at the Virtual Engineering Lab are already working toward the next goal. To develop a virtual vehicle that allows a full experience and is fully operational, they have launched a research project at Stanford University in California.

Users are to be able to feel the virtual concept car in the future. To make this possible, a system of fine, pressure-sensitive pins simulates all the shapes and contours of the interior. This will allow the user to feel the surfaces and controls that do not exist in the real world. "If we could actually feel a virtual vehicle, that would take us to an entirely new dimension," Ostermann concludes.
