Using real-world data to calibrate a driving simulator measuring lateral driving behaviour

This study presents the development of a driving simulator for studying lateral driving behaviour to support the development of lateral active safety systems. A comparative analysis was carried out of the differences in lateral driving behaviour in the driving simulator and in the real-world environment. Based on the analysis, the authors proposed a model that enables the driving simulator to be used for the study of lateral driving behaviour in replacement of the instrumented vehicle in real traffic. The model can be considered reliable after further four driver´s tests. The research results show that the developed driving simulator, after calibration using the real-world tests, provides an adequate (with a 10% margin of error) evaluation and analysis tool for the development of in-vehicle lateral safety systems.
