In the first place, this is due to the much higher influence the rider of the two-wheeler has on the stability of his vehicle. He does not only have to stabilize the system actively at low velocities but he can also destabilize it easily by inappropriate interventions.
In order to make a statement about the applicability of assistance systems for powered two-wheelers, the interventions that an unprepared driver can be expected to handle without forcing him to an undesired (= destabilizing) reaction are investigated. Riding studies are conducted for this purpose, in which experts assess which interventions are controllable for the average rider. The experts are riding instructors and trainers that are familiar with assessing the capabilities of weaker drivers.
Based on the results of these expert studies, participant studies will be performed in order to investigate how „normal riders“ handle the interventions and which potential these interventions provide in terms of safety. The participant tests are conducted within riding experiments on a closed-off test area as well as on a dynamic motorcycle riding simulator.
The aim of this research is to determine the boundaries that the rider sets for the applicability of assistance systems for powered two-wheelers and to assess, to which degree laborious participant studies can be replaced in future by simulator tests.
