Design Possibilities for Vehicle Roll Motions as Feedback for the Driver during Automated Driving

When driving a partially automated vehicle, it is necessary for the driver to have a good awareness of the automation system to meet her/his new task as a supervisor of this system. Hence, feedback about state transitions and intentions of the automation is crucial to obtain or increase the driver's awareness of the automation system. Typically, such feedback is presented visually to the driver. By contrast, in this contribution feedback is communicated to the driver via active roll motions of the vehicle body, realized with an active body control system. In a driving study different roll motion designs shall be evaluated for announcing an upcoming lane change maneuver. The design possibilities of the roll motions and their variations as well as some research questions of this driving study are presented in this paper.
