Inappropriate trust in the capabilities of automated driving
systems can result in misuse and insufficient monitoring
behaviour that impedes safe manual driving performance
following takeovers. Previous studies indicate that the communication
of system uncertainty can promote appropriate
use and monitoring by calibrating trust. However, existing
approaches require the driver to regularly glance at the instrument
cluster to perceive the changes in uncertainty.
This may lead to missed uncertainty changes and user disruptions.
Furthermore, the benefits of conveying the uncertainty
of the different vehicle functions such as lateral and
longitudinal control have yet to be explored. This research
addresses these gaps by investigating the impact of unobtrusive
and function-specific feedback on driving safety
and user experience. Transferring knowledge from other
disciplines, several different techniques will be assessed in
terms of their suitability for conveying uncertainty in a driving
