Functional diagram of the global discomfort assessment for vehicle passengers by means of simulation (UDASIM)


As part of the program “SME-innovative: ICT“, the Federal Ministry of Education and Research (BMBF) supports the research project UDASim in cooperation with the DLR Project Management Agency.

The project UDASim aims to develop a simulation-based method for global discomfort assessment for vehicle passengers. The objective is the investigation of global discomfort by means of an artificial neural network, which obtains all relevant influencing factors from complementary digital manikins (CASIMIR, RAMSIS, AnyBody). 

For this purpose, the digital manikins are adapted for a combined simulation and further enhanced to calculate all relevant influences. The artificial neural network is trained with data from trials with test persons and the entire procedure of global discomfort assessment is validated with further trials with test persons and combined simulations.

The unrivalled coupling of all three models, which are already used by vehicle manufacturers in different phases of product development, allows for comprehensive product optimization in consideration of ergonomic and comfort-relevant factors. Application relevance and thus the use of the results is ensured by the participation of Daimler, BMW and Ford as associated partners.
