How the driver wants to be driven - Modelling driving styles in highly automated driving

In recent years considerable research has been carried out in the field of autonomous driving as it opens up new opportunities for individual mobility. The increasing level of automation associated with changes in the driver’s role from active to passive raises new questions of driver-vehicleinteraction. This research focuses on a fundamental aspect of this change: Is it possible to model a customized automated driving style based on manual driving that makes the driving experience comfortable for the driver? A driving style experienced as comfortable is a basic condition for the wide acceptance of automated driving. Two studies will be presented in an overview. First, a driving simulator study was used to derive driving parameters to provide an automated driving style experienced as comfortable. Some of the thereby found parameters essential for the perceived comfort like acceleration and braking is tested in a subsequent field study on the test track Sachsenring. Preliminary results indicate that driving parameters concerning longitudinal control have a high impact on subjectively perceived comfort.
