Purpose and goal

The purpose of the project is to improve the accuracy of simulation of the car´s trajectories, thereby contributing to improved development and validation processes for, for example, active safety functionality. A method of finding tire model parameters by measuring an instrumented conventional car on test track has been studied. Projects show that this can be achieved even with small means and simple sensors. Furthermore, the project shows the importance of having the right models to achieve high simulation precision.

Expected results and effects

By simple instrumentation of a conventional car on the test track, it is possible to acquire the data needed to adapt tire models to new conditions, such as new road surfaces. This enables a fast, simple and time efficient process to improve and customize simulations, which in turn can improve development processes for, for example, active safety.

Planned approach and implementation

The project has been driven by experimental trials in the form of two major measurement campaigns, where measurements on the test objects and extensive reference measurements were made. Between and after the campaigns, analysis and simulation have been made to consolidate theories and approaches. The comprehensive reference measurements have enabled a systematic approach to identify weaknesses not only in the investigated process but also in reference measurement equipment that is not the standard practice in similar projects.

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
