Lars Eriksson was born in Sweden in 1970. He received the M.Sc. degree in Electrical Engineering 1995 and the PhD degree in Vehicular Systems in May 1999 both from Linköping University. During 2000 and 2001 he spent one year as a post doc in the Measurement and Control group at Swiss Federal Institute of Technology (ETH) in Zurich. Since then he has been at Vehicular Systems as Assistant and Associate Professor and now as full Professor. He is currently managing the Vehicular Systems engine laboratory. His research interests are modeling, simulation, and control of vehicles. His research interest spans the broad area from energy efficient vehicle propulsion into in-cylinder processes, where his research pioneered the real-time control of combustion timing using information obtained from the ion current. As manager of the engine laboratory he has well established contacts with researchers both in academia and in industry.
Model based development is seen as an key methodology for handling the complexity and guiding the development and optimization of future complex hybrid electric vehicles. It can help reduce the time to market and thus increase the pace of innovation, but a cornerstone for a high innovation pace is the availability and reusability of models. In this presentation we will follow the initiation and development of a diesel engine model that has been much used and evolved over the years to become used in a wide range of applications beyond the initial intentions. Starting as a model for a long haulage truck it has been refitted to a passenger car, reused in a diesel electric powertrain in an off-highway application, reused as building blocks for a large marine engine model. It is now the cornerstone in a benchmark model for development of planning strategies in future connected vehicles as well as in a model for studying hybrid vehicles and how the powertrain interacts with the after-treatment system. Much of the success of the model builds on the fact that it is component based, systematically developed and adapted to a real world engine and that it was released as an open source model that could be freely downloadable and modified.
