The present thesis project was done in collaboration with Magneti Marelli’s powertrain department located in Veneria Reale (Italy, Turin). Magneti Mareli is an Italian developer and manufacturer of high-tech components for the automotive industry. Initially it was a producer of magnetos for both the automotive and aviation industries, currently it deals with intelligent systems for active and passive vehicle safety, including design of vehicle control systems. In this thesis an electro-hydraulic actuation model was developed for real-time hardware In The Loop (HIL) applications to support model-based development of a WDCT controller which must be able to control the filling phase of the clutch actuators. The model comprehends a detailed physical description of a pressure control valve and of a nonlinear actuator. The system identification was done by means of experimental data collected from several tests. Clutches thermal behavior was also modeled to support the development of another controller whose aim is to cool down both the clutches according to safety and fuel-efficiency criteria. Two different simplified thermal models will be shown and the simplest one was chosen for code-generation and further development. Besides those activities, this thesis deals also with the development of a model-based software generation of a Torque Converter thermal behavior. The aim of this project is to estimate the torque converter oil temperature when the physical sensor used for doing so is not working. For this purpose a simple model is required in order to estimate the desired temperature in real-time. The model was identified through the use of experimental data.
