Hybrid Models of an Automotive Driveline

Abstract In this document, two hybrid models of an automotive driveline, difiering in their levels of abstraction from real system behavior, are proposed. One model is very detailed, involves discrete dynamics with numerous states and its aim is to provide a powerful tool for verifl- cation. From the latter a reduced{order hybrid model, which is more indicated for synthesis purposes in the design of controllers/observers, is obtained analytically. Both hybrid models have been used with encouraging results within the research activity \Hybrid algorithm de- velopment for the actual engaged gear identiflcation in engine control application, simulation and experimental data processing" developed by PARADES during the year 2004. This research has been sponsored by European Community Projects IST-2001-33520 CC (Control and Computation) 1
