The Influence of Yaw Movements on the Rating of the Subjective Impression of Driving

This paper deals with the influence of different scaled yaw movements on the rating of the subjective impression of driving. Extensive test series have been made with a 1 degree of freedom system, which puts the test person into a simulation environment. Different kinds of drivers (from everyday drivers to professional test drivers) had to pass different driving situations to rate them subsequent via questionnaire or pushbutton. Assuming that higher yaw rates are acceptable for the driver this should be a kind of a worst-case scenario, because nearly every driving situation, which contains yaw movements, is connected to the appearance of sway accelerations. This is the most important mechanical control variable when driving a vehicle and will probably raise the acceptable yaw rates. In the next step this simulator with its yaw table has been mounted on a stewart-platform hardware- and software-sided. This assembly works properly under normal driving conditions, but reaches its dynamic limits rather fast when adjusting higher yaw rate. For this research purpose, the use of the described configuration of the motion system is restricted to accurately defines driving maneuvers, which require a special motion setup, a suitable database and well instructed test persons. At present, the authors prepare a test series to get more information about the influence of sway acceleration on the subjective rating of different yaw rates. This may lead to new approaches in the development of motion systems and motion algorithms.
