This paper outlines a research project at FKFS aiming for systematic objectification of the passengers comfort in highly automated driving situations. Therefore, a modular vehicle controller model as well as realistic and comfort-relevant driving scenarios were implemented to complement the virtual test environment of the Stuttgart Driving Simulator. The real time capable controller allows simple online adjustments of its control behavior. Besides the controller, an exchangeable, commercially available vehicle model represents the plant vehicle in the simulators real time simulation network. The environmental interaction and traffic vehicles are also implemented with the help of commercial or proprietary tools. The relevant test-scenarios are iteratively determined and created. They contain mainly motorways, country roads and appropriate connections in accordance with German road construction guidelines. The 3D-Road-Surfaces consist of measurement data, synthetic random surfaces and hybrid variants. The measurement data used maps certain motorway parts, which are particularly relevant for comfort. As the measurement data contains only two tracks, an extrapolation method expands it to a 3D surface by using synthetic shapes in lateral direction. This approach turned out to keep the relevant road specific singularities, like transverse grooves in the roadway, while representing a realistic surface for a whole motorway with several lanes. First project results indicate that not only the control-systems behavior or the travelled scenario affect the passengers comfort, but also interdependencies between controller and scenario have a relevant impact. Pursuing the projects target of a comfort assessment method for highly automated driving functions, a subject study is currently in progress to gain subjective comfort ratings with statistic relevance. Due to the found indications, the study will focus on the lateral trajectory planning for motorway lane changes. More precisely, the passengers comfort on asymmetrically shaped lane change trajectories will be evaluated in contrast to symmetrical shapes and in dependence on different driving situations. As a next step towards the aimed comfort assessment method, the captured subjective ratings are to be correlated with objective criteria further on.
