TThe modelling process for a DCT has been introduced, including prototype TCU, hydraulics, gearbox, synchronizers. This DCT model is coupled to a vehicle model with engine and EMS. The model can be used at different stages of the design process and for different purposes, from control strategy development to hydraulic module design. Based on this high frequency model, a real-time model has been derived that includes driveline modes up to 50 Hz. This model is suitable for Hardware-in-the-loop simulation, or for exporting as a s-function to Simulink (or other control development environments). Due to the preservation of fundamental dynamical effects in the real-time model it is able to reflect a physically correct transient behaviour and thus does not only permit pure functional testing on a HiL system (which is the typical scenario with standard models nowadays), but also the execution of pre-calibration tasks. Using key features of the Modelica language (object-oriented, acausal/equation based, continuous-discrete models), it is possible to obtain high quality plant models that can be smoothly integrated into the development process of a new transmission.
