Estimering av parametrar i en longitudinell fordonsmodell (Swedish)
Abstract [en]

System modelling has an important role in vehicle development cycles. Hardware field tests are often replaced by simulations, especially during the preliminary design stages. Although system modelling is a time consuming task, significant amount of the overall development time and resources can be reduced if an accurate model is available.

In order to develop a good simulation model, a sound method for parameterising the model is desired. A favourable parameter identification not only provides an accurate model, but also requires less resources both time-wise and monetarily.

In this thesis, a model for the longitudinal dynamics of a passenger vehicle is presented. Unknown parameters in the model are estimated and the model is validated with measurements obtained experimentally. It is anticipated that the model will be used in a dynamometer, where the longitudinal forces on the vehicle are simulated and the corresponding torques are exerted on the driving wheels.
