Abstract (englisch):
Currently, the automotive industry shifts from classic Cyber-physical Systems~(CPSs) development to the development of CPSs with digital twins.
However, while most digital twins assume formal/formalized models, in practice many engineers stated to employ informal models or sketches during the development of CPS with digital twins.
Thus, to investigate the purpose and use of informal models in the automotive industry, we conducted an expert survey within the SofDCar project.
In detail, we set up an online questionnaire asking participants from industry and academia about the way they employ informal models in their contexts.
The survey indicates that informal models are widely used during the conception phase and for communication and documentation.
Thus, we maintain that digital twin architectures for the automotive industry must incorporate informal models, as additional artifacts documenting and communicating design decisions.
