Regeneration offers new possibilities for the vehicle longitudinal dynamics which can be controlled by different interaction concepts. These longitudinal control interaction concepts can be characterized by different driving experience dimensions and cause a differing driving behavior. With the help of a subject study in a realistic city traffic environment these aspects are analyzed (27 subjects). The analysis of the subjective experience is summarized by the results of the 'AttrakDiff mini' that shows an increasing attractiveness by a rising deceleration level. This positive attractiveness mainly results from a stimulatory challenge offered to the driver to adapt his own driving behavior to do almost all decelerations only with the gas pedal (One-Pedal-Challenge). This adaption can also be observed in the results of an analysis of objective data, recorded during the study. The results show that with an increase of the drag torque more decelerations are fulfilled with the gas pedal and the drivers adapt their driving behavior to do almost all decelerations with the gas pedal. Analyzing the results of the noticeable drag torque (concept 3, ax=-1.5 m/s2) the driver often call the full amount of gas pedal deceleration, which can be observed in the results of pedal usage and the acceleration behavior. The drivers of concept 4, strong drag torque (ax=-2.25 m/s2) often modulate the deceleration by the gas pedal and call rarely the full amount of deceleration nor additional deceleration by brake actuation.
