Identification Model

Today’s vehicles are under strict legislative requirements regard-ing emissions and thus need proper control and diagnosis func-tionality to secure operation within the prescribed limits. A key characteristics is the interplay between modeling and informa-tion fusion, using information from in-vehicle sensors, databases, as well as communicated information from other vehicles and infrastructure. The core of the project is in information integra-tion. One particularly interesting area is systematic and efficient analysis of combustion engine data. These have a direct impact on the performance and selection of control strategy. The data is very informative but to get reliable results, it is necessary to also combine the data with information from experts. Recent results concern the development and evaluation of systematic methods that combine traditional measurements with a paramet-ric description obtained from expert knowledge in a systematic way. These methods have been applied to the problem of ana-lyzing combustion engine data. Problem outline Control of the combustion process is very important since it di-rectly influences both emissions and efficiency. Predictive models (mixing, turbulence etc) are not yet reliable, analysis of engine data is an important tool. Measure cylinder pressure make Heat release analysis. The goal is to have a sys-tematic method that answers the important questions • How was the fuels chemical energy converted to thermal en-ergy and work? • What is the position and speed of combustion
