Fraunhofer Institut für Verkehrs- und Infrastruktursysteme IVI

The Fraunhofer Institute for Transportation and Infrastructure Systems IVI, headquartered in Dresden, employs a total of around 150 scientific employees at three locations. The institute collaborates closely with the universities TU Dresden, TU Bergakademie Freiberg and Technische
Hochschule Ingolstadt. Its transport-related research work ranges from the field of vehicle and propulsion systems to intelligent transport systems, and it also covers the areas of disposition, logistics and digital business processes.
The Fraunhofer IVI has many years of work experience in the field of innovative propulsion systems for public transport. The focus of these projects is on fully electric and hybrid propulsion systems. The Fraunhofer IVI’s expertise is based on numerous measuring campaigns in public transport vehicles and a detailed knowledge of vehicle technology – especially regarding innovative propulsion systems and their implementation in test vehicles.
The experience gained in the field of public transport vehicle technologies was incorporated into the vehicle simulation model IVIsion, a development of the Fraunhofer IVI. The product, which is successfully employed in a large number of projects, describes entire vehicles with great precision, combining detailed component models for powertrain, energy storage systems, auxiliaries, cooling and heating, driver and passengers, as well as interaction vehicle – environment – road into one highly complex simulation model. With the help of this model, it is possible to make a range of precise prognoses such as for the energy consumption of specific vehicle and propulsion configurations under given operational conditions.
