This paper presents the detailed model of a double clutch actuator with a suitable control algorithm. Firstly; there is an introduction into the theory of a double clutch transmission and the aim of this project. The simulation model with a Dymola® and a MATLAB®/Siulink® part is discussed. The library of a vehicle model with a highly det hydromechanical clutch is introduced; which includes models with different levels of detail. The modeling of the hydraulic and the mechanic parts of the clutch actuator is discussed; concentrating on the problem of determining the parameters of the actuator modules e.g.; the hydraulic valves. Some parts could not be used from existing Dymola® libraries; in those cases; new models are created based on Modelica code.
