Functional Mock-up Interface in Mechatronic Gearshift Simulation for Commercial Vehicles

Mechatronic shifting simulation of automated trans-missions in commercial vehicles is used for optimi-zation and development in today’s truck engineering departments at Daimler. Within the ITEA2 project Modelisar in cooperation with ITI GmbH and SIM-PACK AG this application served as a usecase for proof of concept of the newly developed Functional Mock-Up interfaces (FMI). Utilizing these standard-ized interfaces models from different tools are cou-pled to build up the overall system for the mecha-tronic shifting simulation. The coupling via FMI for Model Exchange was achieved for control modules from MATLAB/Simulink into the SimulationX powertrain model and secondly from the 1D-multiphysics powertrain in SimulationX into multi-body vehicle in SIMPACK. Furthermore FMI for Co-Simulation was investigated in a pure Simula-tionX framework for the powertrain model. Very promising results can be observed as for modeling as for simulation processes. The FMI technology has clearly shown its capability to be applied in the pro-ductive simulation process
