CADJapanGermany: HF

Japanese-German Research Collaboration on Connected and Automated Driving: Human Factors



  • Project type: Funded by the Federal Ministry of Education and Research
  • Research area: Automated driving
  • Contact: Burak Karakaya, Birte Emmermann
  • Project period: 09/2019 - 12/2022


The collaborative research project CADJapanGermany: HF consists of a consortium of the two countries Japan and Germany, which are each funded separately from one another. On the German side, funding is provided by the Federal Ministry of Education and Research with the project management organization VDI / VDE Innovation + Technik GmbH and consists of the partners Technical University of Munich, Chemnitz University of Technology, Technische Universität Dresden, Ulm University and the German Aerospace Center.

On the Japanese side, the consortium also includes four universities, the University of Tsukuba, the University of Tokyo, Kumamoto University, Keio University and the National Institute of Advanced Industrial Science and Technology (AIST). To ensure that the research activities described in this project are linked to current technical and economic developments, the automotive industry will support the project in the form of an annual expert workshop.



Automated vehicles have been the global focus of automotive research for several years. Manufacturers on all continents try to prepare their vehicles for all traffic systems worldwide. Germany is actively taking a step in this direction over the next three years and is doing targeted research with Japan, which is also strongly automotive-oriented, on the upcoming topics of automated vehicle guidance.

Due to the progressing international development of automated driving functions, which in the future will take over more and more driving tasks of the driver, a profound exchange is started alongside the already existing national projects in connection with human factors. This exchange is built up through Japanese-German expert workshops, guest researcher exchanges, joint publications or educational / teaching activities.



The CADJapanGermany: HF project investigates the topics of external communication, general and professional driver training as well as interaction and transition (switching between automation levels) in several sub-studies and in intercultural exchange, as these can be affected to a large extent by intercultural differences.

The automation levels (up to level 4), which are of high relevance for a successful introduction of automation in urban and suburban scenarios, are brought into focus. The next stages of research and development in the area of ​​human factors will benefit from the project knowledge for the exchange of methodical standards, a common understanding of usage scenarios, intercultural comparisons and the identification of invariants for possible standardization.
