Dynamic modeling and control of a car transmission system

In the paper, the dynamic model of a car transmission system is taken into account and a simple control strategy for controlling the transmitted torque is presented. All the main components of the transmission system (the engine, the clutch, the gear-box, the differential, etc.) have been modeled in details by using the graphical modeling technique named power-oriented graph. A particular attention has been paid to the model of the clutch system because of its importance in the modulation of the transmitted torque. A simple control strategy for controlling the torque transmitted during the "start" of the car is also presented. Simulation results show the usefulness of the model and the effectiveness of the presented control strategy.
