ABSTRACT
Electric vehicles offer a new degree of freedom in the design of driving torque in coast load conditions. Therefore, new possibilities for the vehicle longitudinal control are obtained. Different driver control strategies are derived and driving experience aspects of the longitudinal dynamics are presented in this contribution. The driver experiences can be classified by the dimensions safety, discomfort, energy efficiency and further specific aspects of the longitudinal control. The characteristic of these driving experience dimensions is analyzed using the results of a subject study (27 subjects) in a realistic city traffic environment. The results of the study show that besides of the well known driving experience dimensions discomfort and safety the newly identified dimensions energy efficiency and the experience of the longitudinal control are responsible for the differing driving experience in the concepts. Furthermore, the results of the study show an adaption 264of the driver to the tested interaction concepts, which acts as a stimulation (e.g. One-Pedal-Challenge) and in addition can be used to increase the vehicle efficiency.
