Authors initiated trial and evaluation of a new method to connect physical ports of acausal model and causal signal ports using FMI as an activity of technical committee of JSAE (Society of Automotive Engineers of Japan). We propose a way of model export and connection using new adaptor models. This method was tested by a benchmark model of a control system. Simulation results for the benchmark model showed good consistency between the original acausal model and the connected model using FMUs separated from the original model by this method. Also a guideline about using FMI for the model connection using this method was made in JSAE and is distributed to general users of Japanese automotive industries. Finally expectations about future enhancement of FMI for model exchange and circulation between different companies are presented.
